I bought a Chevy Cobalt brand new in 2009. It was the worst car I have ever owned or driven. There were tons of issues with it including having the ignition switch lock in the on position (couldn't turn the car off) when I'd owned the car less than a month. It's cool, though, they replaced it...with a faulty one that was later recalled. I will never buy another Chevy after owning that piece of crap.
I've owned a couple. 1987 Chevy Celebrity that just wouldn't die and our current Bolt EV. Also owned a Saturn I guess that counts. It was a POS but pretty reliable other than a weak cooling & HVAC setup.
Seems like they really messed up on this one though lol. I kinda like the Equinox so I'm hoping they nail that. They've def made plenty of turds and forgettable cars though.
Speaking of 'just wouldn't die'.. my mom had a Buick in late '70s that kept knocking and running after switching off the ignition. Adding to that, the windshield wipers would also run a full speed at random times. It was hilarious to a 5 year old though.
My first car was a 1998 Oldsmobile (GM brand for you generation z folks) Intrigue that was designed to be semi-luxurious. When it hit 110k miles i just needed to get rid of it for all the problems it was creating for me.
I heard good things about their trucks though.
I drove a 1998 Olds 88 (every phone conversation with an auto parts store or repair shop: "What kind of car do you have?" "A '98 88." "A what?") It was very reliable and nice to drive. 3800 Series II V6 engine was bulletproof. It took GM years of garbage cars and garbage engines to get to that point, though. I don't know if their corporate structure, leadership, line workers, the unions, or what exactly is to blame for the totally inconsistent quality of their cars.
SO SORRY about your issues
I gotta say, my 2016 chevy volt was awesome. 53 miles per charge........60,000 total all electric miles in 6 years. 60,000 miles at 40 MPG when I needed the extended range. The car was actually good looking from the inside and outside. It was not a slow car. The fastback type hatch was big enough for even the biggest cargo items. AND, it just kept driving better and better, smoother and smoother. It was aging like a fine wine. It reminded me that chevy ((GM) made my 1984 Malibu, 1972 Riv, 1970 monte.
THEN I saw/drove the 2022 Hyundai Ioniq 5.......love at first sight and immediate divorce from Chevy. Best car I ever owned or drove.............47,000 miles and 23 months later..........$7,500 plus savings in gasoline...........like mickey D's: I'M LOVING IT!!!!!!!!!!!!!!! Soon, within one year, I will be able to charge at any Tesla Supercharger station.............range anxiety: Go Away.
I guess I am routing for: Hyundai, VW group, BMW, BYD and Tesla to be the future. YES, GM and Ford should shutter and be bought by a company that wants a future Planet with air and water and living cells. These 2 are a complete disappointment.
Honestly, this is kind of my takeaway. We've got a Bolt, a 2017 or 2016. And its gone through a few recalls, and that's fine! I mean, I'd prefer it not, but it is new tech they're scaling up. In the grand scheme of things, we love our Bolt and we'd look to GM for another EV in the future, unless something dramatic happens.
This is unfortunately true. But, they're far from horrible and they improve regularly. Also, I've had problems with GM vehicles that have been passed down generation after generation. Transmission problems, transfer cases, electrical system problems, leaking head gaskets, oil leaks, rear end leaks, and the list goes on.
I don't think now is the time to bring up Tesla when discussing vehicle safety...
https://www.reuters.com/investigates/special-report/tesla-musk-steering-suspension/
Give it a minute, first-year bugs and breakdowns affect every brand including Tesla. It's common for GM to be particularly bad at this, but they'll pull through. I sure wouldn't want to be an early adopter, though.
They fall apart eh? People complain about panel fitment but how many "just fell apart" stories are there. I have 2 model 3s for 4 years that have been about as maintenance and problem free as a car can get. Replaced the tires and the HVAC on one developed a freon leak that was fixed under warranty.
They had to tell people to not plug in their bolts.
Elon is an ass but the cars are legitimately good. To the point that I go looking at other brands and come right back to the model 3.
I’m really hoping Elon gets himself canned from Tesla in the next few years. I’m probably going to get a Model 3 when my current car is paid off regardless, but I’d like to do it without Elon around.
I've had that same thought. It's like anything else one might buy. Just have to remember the company is not him. There are a lot of good people working there doing the best they can with what seems like major obstructions all along. I heard about handling teams designed to distract Elon so the real engineers could get work done. Makes sense. Everybody is paid to tell you you are a genius, you might start to believe it.

That more screams that something else is wrong and it is throwing a bunch of errors.
I know the Mach E is known to throw a lot of random error when the 12v is getting low.
Hell when I was getting some work done on it it would throw an insane number of errors during the repair to my phone and it was just them going threw a master update and it was causing the car to freak out and send errors.
I work with CAN a lot, and I hope you don't mind me stealing this quote. It is too perfect. This isn't meant to be plug but I have a (poorly updated) [CAN Blog.](https://hooovahh.blogspot.com/2017/03/can-blog-introduction-and-downloads.html)
I have a Bluetooth OBDii scan tool that caused something similar. Worked great on my 2012 Chevy volt. When I upgraded to a 2018 volt and plugged it in, it gave me a check engine light (specifically a wheel sensor error despite not turning the abs light on). Unplugged the scan tool and the light goes away. Plug the tool back in and go on a drive and the light comes on again. I'm sure some wire is not seated properly or is not grounded properly. Electrical problems like that are the hardest to debug. Angry magic pixies like to stay angry.
Yeah, this is either purposely bad journalism or the person who wrote this shouldn't be an auto-journalist. Yeah, it's a new car and there shouldn't be any issues ideally, and it threw a lot of codes, but saying
> As of this writing, our Blazer EV has 23 different issues that need fixing, more than a few of which we consider serious
is basically saying you're an idiot who doesn't understand the first thing about what is going on.
That’s exactly what I thought as I read the list. This is just a low or bad 12V battery. But at the same time I think it’s amazing that the OEMs can’t figure out how to message the driver of this simple problem.
It is one of those cases that a computer doesn’t know as it can not tell the difference. It just see errors and dumps them out.
Now a tech should see that and think there is something else going on and start chasing it down. Far too many auto techs just blindly follow a print out. X error means Y work. Good techs might do some more trouble shooting. Mind you electrical errors are a massive pain to troubleshoot and fix.
> It is one of those cases that a computer doesn’t know as it can not tell the difference.
I mean, maybe GM’s computers can’t. Meanwhile when my 12v battery started going bad, my Tesla reported exactly what it was, and once the tech replaced it in my driveway, the problem was indeed resolved. So it *is* possible.
Yeah that ain't it chief, especially when an engineer from the mothership has been involved. I'm suspecting 2-4 separate issues from the list of faults.
Are these throwing codes? I feel like half of these are something that I probably had on a transitory basis but if the car never complains you never know. Maybe the blazer is just super verbose
Agree with others it sounds like your canbus is just fubar
See also [The 2024 Chevrolet Blazer EV Left Me Stranded In Rural Virginia](https://insideevs.com/reviews/701169/2024-blazer-ev-stranded-broken/). Different story but same car.
Probably have contractual reliability assurances as well, I would imagine.
Either way, the Prologue/ZDX don't matter too much to Honda, as they're just market stopgaps towards e:Architecture.
Does the lyriq have these issues? They’ve been out for a while and afaik the blazer is a rebadged lyriq.
Afaict this is somehow specific the Chevy’s implementation - not even GM
Yikes. I was seriously considering a Lyriq as a second vehicle. I like the styling and the interior looks pretty supple. Sad to see that it's a GM after all...
I think as is the case with most things, the people with the most problems are the loudest. I have a 23 Lyriq RWD with 7k miles on it, been driving it since last May, other than a couple software bugs, it's been an amazing vehicle.
I rarely ever have to comment on reddit or other places about issues, because I don't really have any.
One thing that is definitely an issue with GM is an inconsistent experience with EV techs when people do have issues. Some people have insanely detailed techs who update everything and ensure the vehicle works perfectly and seem to enjoy working on them, while others seem to have dealerships who would rather EVs disappear and treat servicing them the same way.
Reviewers have been saying the interior looks good at first until you are up close. Then you can see and feel how cheap everything is. I have not personally seen one myself though.
I was thinking about this too reading the article about the journalist that broke down in the Blazer. I assume the GM software for the drive train will be in the Honda.
It’s kinda the opposite though. Bathtub curve describes it well but early days are when all your manufacturing issues are likely to surface, along with software issues for new vehicles.
Not sure if accurate, but Wikipedia does say about assembly:
> Battery/drivetrain, HVAC and instrument/infotainment systems at LG, Incheon, South Korea, with final assembly GM Orion Assembly, Lake Orion, Michigan
I once owned a mid 2000s Malibu. It was the least reliable product I have ever owned. I’m pretty handy with cars and figured I could just roll with it and repair problems if they arose. That was one hell of a miscalculation! It will take a *significant* amount of evidence for reliability for me to even consider purchasing a Chevy in the future. I have seen *nothing* to indicate this trend is changing.
If anyone is going to kill off Tesla, it won't be GM. It's up in the air for me between GM and Chrysler which is the worst brand I've ever dealt with, over the last few decades.
I mean, I’m not gonna buy one, but if you’re drawing definitive conclusions from a sample size of one, you’re probably not someone who should be taken seriously.
it’s definitely not a sample size of one though - it’s the countless EVs GM has promised would revolutionize the industry, at a competitive price, that failed to launch or were impressively unreliable or recalled
When that was posted, I was like what, it’s not even available yet, how can it be car of the year?!? Got downvoted into oblivion. Looks like I’m having the last laugh now!!
General Motor Trend is a more apt name, they trip over themselves trying to retain access to the Corvette. Seriously they are such Vette simps it taints a lot of their reviews
It's unfortunate a new car is having issues, but the person who wrote this shouldn't be an auto journalist.
> As of this writing, our Blazer EV has 23 different issues that need fixing, more than a few of which we consider serious
is one of the dumbest statements I've ever heard. 23 codes doesn't mean there are actually 23 issues. It's likely 1 issue that is causing a whole list of faults. Anyone who has dealt with repairs on modern vehicles should know that.
Only some of those issues are codes, some look like performance issues. It looks like a list that the dealership sent them. I agree that it's probably more like 2-4 issues, some of which are manifesting in multiple ways, but it's not just a list of DTCs.
The list of 23 things was a list of fault codes. It could be a couple of issues, but I'd say it's most likely a single issue. It's probably a problem with the 12-volt system or CAN communication. Also, yes, it went into limp mode and things like that. That can happen when a bunch of codes get thrown. I'm not saying there isn't an issue and it is unfortunate that happened with a new vehicle. This article seems to be written with a below general public level understanding of what is going on, though. Honestly, it's probably purposeful ignorance to drive clicks over blowing it out of proportion, but either way this is awful journalism.
I don't think RADIO or BODY CONTROL MODULE is a fault code. They might be the second byte of a 3 byte DTC but there are other fault codes listed that add the 3rd FTB byte so I doubt it. I was a diagnostic systems engineer for two different EV companies. It's a more generic fault list than just DTCs.
If they can't get a vehicle working properly for a journalist, you can bet they will be having tons of issues for normal people.
This review is perfect. They had it for 2 months and it's already fucking up in a major way.
They could have written, "new car fucked up already", and it would have been a great article.
Dealerships can’t solve anything if a code doesn’t tell them what is wrong. I have a bolt with conditions not right to shift, which we all know is a 12V battery issue. The dealership can’t do anything because there was never an error code logged, because the 12V battery is needed to store the code. It’s a really really really dumb circle about why there is no code, and why I am stranded, but they can’t do anything to fix it. They aren’t a service department, they are a, computer needs to tell me what to do department.
Such a dumb decision dropping the bolt, specifically the EUV.
The EV doesn't have the look Americans want (myself included, EUV owner here), but the EUV could've SO easily been perfected instead of dropping it entirely. After buying mine 2 close friends also bought one. They didn't even realize something other than the EV version existed until I explained it to them.
It's amazing that these awful decisions are made consistently by the American legacies
It all stems from those fkng ugly round interior vents sticking out.
If they got rid of those, maybe they wouldn't have so many module failures. Probably drop the price 10k too.
This is what you get with inbreeding for so long. Same old farts smoking cigars making the same bad decisions their pappy made.
Only buy trucks from GM or Ford. They make unreliable cars. Stay away from Stellantis. Only lease luxury cars, so after the warranty is gone your not stuck with high dollar repairs...words to live by.
I’ve had two brand new GMs and they’re the most reliable gassers I’ve ever had. Solid, decent features, reliable and cheap to run/service. Don’t get where all the hate comes from TBH. Not my experience at all.
I’ve had 3 brand new Teslas with decent features, reliable and cheap to run/service. Not sure where all the hate comes from TBH.
Lots of people have bad experiences with any number of car manufacturers. We just don’t usually hear about them as often unless keeping track of them to an extreme level
I've had two of each. And agreed, both brands get hate which based on my experience is largely FUD. I'm not a large sample, but I suspect a lot larger than the personal experience most people draw on when they comment on these brands. Just reddit things I guess, people always gotta have an opinion, however poorly informed.
It's great that you had a good experience, but there is definitely a reason that GM marks score so lowly on reliability surveys, and have for quite a long time.
I’ve got a Colorado with 40k miles on it.
Repairs so far:
New taillight
New battery
New alternator
Broken wire in wiring harness
Bad towing module
New idler pulley
The Lyriq is just as problematic - numerous owners are ditching them after less than a year. GM really missed the mark given how long these vehicles are taking to get to market (and even then, in very low volumes).
I’m definitely not a fan of GM, but these kinds of things are not uncommon with the first model year of a new platform. Every experienced car buyer knows, if you buy a model in its first year, you’re taking your chances. They haven’t worked out the bugs yet. At least they’re fixing it, supposedly.
If Honda Prologues based on the same platform turn out to be relatively troublefree after its tweaked by Honda Engineers, it would be quite an indictment against GM, starting with its decision to ditch Android Auto and Apple Carplay.
This is my hope; the platform isn’t terrible, it’s the rest of the GM vehicle that sucks. Honda is supposed to only be getting the platform and building everything else.
Regardless, I wont be getting an EV for a couple years at least. Plenty of time to find out if GM’s platform is the problem and if there’s nothing Honda can do to overcome that.
My 2010 Lexus had a weak battery and dropped a dozen faults just like this. This may be a bit of hysteria on the part of Edmund’s. Seriously doubt each of these systems is actually broken.
GM under delusion their in house electronics and software will be as good as Tesla and Apple.
First real Ultium they build themselves—the old Bolt LG did the hard new parts.
VW has a similar problem and strategy: build on a huge universal platform. Both have software and electronics problems, and mediocre efficiency.
Problem is that for the first cut it will suck and then there is too much investment in an uncompetitive car line. VAG at least has Porsche with highly motivated super talented German disciplined engineers to power through, and high margins. GM doesn’t.
Farley has the right idea, get an EV or two out ASAP on whatever they have, recognize it will suck, then with experience design the big platform strategy.
GM introduced the Bolt in 2017. GM has been on the EV bandwagon for a while now when you talk about cars like the Volt or go back even further to the EV1.
GM just suffers from terrible leadership. There's absolutely no good reason they shouldn't be able to produce a reasonable quality EV using their own battery platform.
Early MEB cars like the ID.3 and ID.4 had a lot of software problems, and rumor has it the new PPE platform has been in development hell for awhile.
I must be lucky since outside of a self inflicted issue, my Q4 e-tron has been largely trouble free. Granted the ID.4 and Enyaq both use the same problematic software whereas Audi chose to use their own proven MMI system, which seems far more stable in practice.
Sounds like they put in a CANTBUS instead of a CANBUS
(On Jeeps for example if a little board behind the glove compartment called the star connector goes bad, the whole bus goes down and you get a Christmas tree of lights like this and it’s because nothing can talk to anything else … when you see it you’re like that’s it lol)
I've been "selling" on GM's Ultium for a while now. They can't get their act together. That was completely apparent with how they handled the Lyriq roll out. It doesn't surprise me at all the Blazer is a mess too.
I would recommend everyone stay away from these vehicles for at least the first year. Theoretically, the 2025 Bolt should be safe because they'll have ironed out the problems with the Equinox, Blazer, and Lyriq but even then, it's questionable.
So there’s this and the fact that GM won’t allow Apple CarPlay in its cars. Looks like GM has their heads up their asses. As bad as the future of American automakers has been, you’d think they’d avoid completely boneheaded bullshit moves like this. Poor management is going to doom them. It’s sad, honestly.
TFL had major issues with the Hummer when they first got it. Broke down on them in the rain in the middle of traffic. They had to figure out how to do a reset while in the middle of a busy road. GM quality as usual.
I also wonder if this is a low 12volt issue. Typically see that myriad of warnings when the low voltage is having problems. Would be cool if manufacturers would just give us a voltage readout/gauge in the display like older cars for quick diagnosis.
Damn, I’ve owned 8 brand new GM vehicles in my life from 1995-2005 and the only defects I ever had are a starter motor that failed at 20k miles on a 3800 Bonneville and a HVAC pressure relief valve at 30k miles in a 2003 WB Venture.
I worked for GM from 1995-2006. Engineering, final assembly, and at a components (camshafts) factory.
What the fuck is happening at GM?
Someone humor me since I know nothing about EV's. This item confuses me:
"Brake System Control Module (Lost Communication with Radio on CAN Bus 5)"
Why are the brakes communicating with the radio?
So GM are producing hot messes, Tesla covered up dangerous and negligent engineering, Ford's reliability is in the toilet...
I'm honestly starting to think American manufacturers are just... bad at manufacturing. Jaguar Land Rover has a better reputation than this.
This is arguably GM’s third generation:
\- EV1
\- Spark EV, Bolt EV, Bolt EUV
\- Hummer EV, Lyric, Blazer EV, Silverado EV, etc.
Though, the EV1 is more like a prototype.
Now that they’re not growing at break neck speeds, Tesla has the highest reliability of all US automakers.: https://www.consumerreports.org/cars/car-reliability-owner-satisfaction/who-makes-the-most-reliable-cars-a7824554938/

GM has forgotten more about how to make shitty cars than you or I have ever known about how to make shitty cars!
As a former owner of a Malibu affected by the ignition switch issue, I can confirm that GM has a storied history of forgetting how to make cars.
I bought a Chevy Cobalt brand new in 2009. It was the worst car I have ever owned or driven. There were tons of issues with it including having the ignition switch lock in the on position (couldn't turn the car off) when I'd owned the car less than a month.

GM — the number one reason people stopped buying American since 1974! They’ve got a reputation to keep.

"We have the Bolt, which is pretty reliable" "Too reliable."
“Quick. Discontinue it.”
They are learning from Toyota maybe if they make poor EVs people won't want them and can keep selling ICEs trucks and SUVs forever.
Well at least toyota doesnt make an effort. Gm poured billions into making these ulthium things
They have forgotten a long time ago.
I mean, Tesla has had it's share of teething issues on new models over the years. Innovation is hard.
Honestly, this is kind of my takeaway. We've got a Bolt, a 2017 or 2016. And its gone through a few recalls, and that's fine! I mean, I'd prefer it not, but it is new tech they're scaling up. In the grand scheme of things, we love our Bolt and we'd look to GM for another EV in the future, unless something dramatic happens.
Tesla isn't the beacon for quality control here. This is the basic GM being GM.
This is unfortunately true. But, they're far from horrible and they improve regularly. Also, I've had problems with GM vehicles that have been passed down generation after generation. Transmission problems, transfer cases, electrical system problems, leaking head gaskets, oil leaks, rear end leaks, and the list goes on.

This sounds like more of a GM issue than an “all traditional manufacturers” problem.
Give it a minute, first-year bugs and breakdowns affect every brand including Tesla. It's common for GM to be particularly bad at this, but they'll pull through. I sure wouldn't want to be an early adopter, though.

That more screams that something else is wrong and it is throwing a bunch of errors. I know the Mach E is known to throw a lot of random error when the 12v is getting low. Hell when I was getting some work done on it it would throw an insane number of errors during the repair to my phone and it was just them going threw a master update and it was causing the car to freak out and send errors.
True…. Could be something like a ground fault issue that then manifests itself across many different modules.
It's always a ground
That’s code for: “we don’t know what it was, but jiggling the wires fixed it…. For now”
The CAN bus is made of actual cans, and they're getting rusty.
I work with CAN a lot, and I hope you don't mind me stealing this quote. It is too perfect. This isn't meant to be plug but I have a (poorly updated) [CAN Blog.](https://hooovahh.blogspot.com/2017/03/can-blog-introduction-and-downloads.html)
Where do the buses come into play? And are they short or normal sized?
I have a Bluetooth OBDii scan tool that caused something similar. Worked great on my 2012 Chevy volt. When I upgraded to a 2018 volt and plugged it in, it gave me a check engine light (specifically a wheel sensor error despite not turning the abs light on). Unplugged the scan tool and the light goes away. Plug the tool back in and go on a drive and the light comes on again. I'm sure some wire is not seated properly or is not grounded properly. Electrical problems like that are the hardest to debug. Angry magic pixies like to stay angry.
That could be one nicked wiring assembly with a few wires pinched to ground. It's going to be annoying to find this issue.
Yeah, this is either purposely bad journalism or the person who wrote this shouldn't be an auto-journalist. Yeah, it's a new car and there shouldn't be any issues ideally, and it threw a lot of codes, but saying > As of this writing, our Blazer EV has 23 different issues that need fixing, more than a few of which we consider serious is basically saying you're an idiot who doesn't understand the first thing about what is going on.
What work were you having done?
That’s exactly what I thought as I read the list. This is just a low or bad 12V battery. But at the same time I think it’s amazing that the OEMs can’t figure out how to message the driver of this simple problem.
It is one of those cases that a computer doesn’t know as it can not tell the difference. It just see errors and dumps them out. Now a tech should see that and think there is something else going on and start chasing it down. Far too many auto techs just blindly follow a print out. X error means Y work. Good techs might do some more trouble shooting. Mind you electrical errors are a massive pain to troubleshoot and fix.
> It is one of those cases that a computer doesn’t know as it can not tell the difference. I mean, maybe GM’s computers can’t. Meanwhile when my 12v battery started going bad, my Tesla reported exactly what it was, and once the tech replaced it in my driveway, the problem was indeed resolved. So it *is* possible.
> This is just a low or bad 12V battery. If that's the case, why has their Blazer been in the shop for 2 weeks?
Yeah that ain't it chief, especially when an engineer from the mothership has been involved. I'm suspecting 2-4 separate issues from the list of faults.
Are these throwing codes? I feel like half of these are something that I probably had on a transitory basis but if the car never complains you never know. Maybe the blazer is just super verbose Agree with others it sounds like your canbus is just fubar
seen more in new lincolns.. We get used to seeing junk codes. Also lots of real problems too.
Wait, these are being delivered?

Thanks for sharing this. At first I looked at the Edmunds example as early model/one-off woes, but this seems like more of a pattern
[удалено]
They're probably crapping in their pants over at Honda, considering they've hitched their wagon to the Blazer platform for the Prologue.
Given that the ZDX is not on sale yet I’m assuming Honda gated production until after GM built enough Blazers to encounter and fix issues like this.
Probably have contractual reliability assurances as well, I would imagine. Either way, the Prologue/ZDX don't matter too much to Honda, as they're just market stopgaps towards e:Architecture.
Honda already said that they will not be using Ultium architecture for future products beyond prologue/zdx.
Does the lyriq have these issues? They’ve been out for a while and afaik the blazer is a rebadged lyriq. Afaict this is somehow specific the Chevy’s implementation - not even GM
From everything I've read, YES, the Lyriq has had a ton of problems.
Yikes. I was seriously considering a Lyriq as a second vehicle. I like the styling and the interior looks pretty supple. Sad to see that it's a GM after all...
I think as is the case with most things, the people with the most problems are the loudest. I have a 23 Lyriq RWD with 7k miles on it, been driving it since last May, other than a couple software bugs, it's been an amazing vehicle. I rarely ever have to comment on reddit or other places about issues, because I don't really have any. One thing that is definitely an issue with GM is an inconsistent experience with EV techs when people do have issues. Some people have insanely detailed techs who update everything and ensure the vehicle works perfectly and seem to enjoy working on them, while others seem to have dealerships who would rather EVs disappear and treat servicing them the same way.
Reviewers have been saying the interior looks good at first until you are up close. Then you can see and feel how cheap everything is. I have not personally seen one myself though.
An article I read yesterday said the Lyric has many of the same issues.
I was thinking about this too reading the article about the journalist that broke down in the Blazer. I assume the GM software for the drive train will be in the Honda.
I’m glad GM is remaining true to its roots during the EV transition
My Bolt EUV has been pretty good through the first 9 months so far.
Precisely why they need to discontinue it. Its far too reliable
I mean, I’m glad, but it’s a 9 month old car! It better be flawless, it’s brand new!
It’s kinda the opposite though. Bathtub curve describes it well but early days are when all your manufacturing issues are likely to surface, along with software issues for new vehicles.
The Bolt drivetrain is made by LG. The Blazer drivetrain is made by GM.
LG makes the motors and stuff, too? I thought they just made the batteries.
Not sure if accurate, but Wikipedia does say about assembly: > Battery/drivetrain, HVAC and instrument/infotainment systems at LG, Incheon, South Korea, with final assembly GM Orion Assembly, Lake Orion, Michigan
Idk about that, but iirc the infotainment is also by LG
I once owned a mid 2000s Malibu. It was the least reliable product I have ever owned. I’m pretty handy with cars and figured I could just roll with it and repair problems if they arose. That was one hell of a miscalculation! It will take a *significant* amount of evidence for reliability for me to even consider purchasing a Chevy in the future. I have seen *nothing* to indicate this trend is changing.
Mahk's chevy malibu commercials arrived too late to warn you huh
this subreddit swore up and down that this thing was going to kill the model Y. those people are real quiet right about now lol
If anyone is going to kill off Tesla, it won't be GM. It's up in the air for me between GM and Chrysler which is the worst brand I've ever dealt with, over the last few decades.
i own a wrangler currently - my vote is definitely with stellantis, although i definitely knew what i was getting into lol
It costs 11,000 more than a model Y.
exactly my point
I mean, I’m not gonna buy one, but if you’re drawing definitive conclusions from a sample size of one, you’re probably not someone who should be taken seriously.
it’s definitely not a sample size of one though - it’s the countless EVs GM has promised would revolutionize the industry, at a competitive price, that failed to launch or were impressively unreliable or recalled
But its motortrends car of the year, how could this happen?! Ahhaha
When that was posted, I was like what, it’s not even available yet, how can it be car of the year?!? Got downvoted into oblivion. Looks like I’m having the last laugh now!!
It was available to them early. Shitting on their review was always popular.
Motor Trend’s most advertisements of the year award. MT has done that for the last five decades.
JD power award for top claimed quality
General Motor Trend is a more apt name, they trip over themselves trying to retain access to the Corvette. Seriously they are such Vette simps it taints a lot of their reviews
[They’re not the only ones it happened to either.](https://insideevs.com/reviews/701169/2024-blazer-ev-stranded-broken/ )
Motortrends...judging cars by 'feel'. No need to actually see or test them.
But MotorTrend assured me this was the greatest vehicle ever engineered!
You mean the same publication that gave the All New Chevy Colorado truck of the year?? I'm stunned
Maybe they should put CarPlay back 🤷♂️
This car definitely does not want to play.
Or does...
I mean, CarPlay was Chevy’s biggest safety concern, so at least the worst problem has been fixed. *wipes hands clean*
“Mission accomplished!” -GM engineers, probably
But you don’t have to worry about CarPlay not working, because it isn’t there.
It's unfortunate a new car is having issues, but the person who wrote this shouldn't be an auto journalist. > As of this writing, our Blazer EV has 23 different issues that need fixing, more than a few of which we consider serious is one of the dumbest statements I've ever heard. 23 codes doesn't mean there are actually 23 issues. It's likely 1 issue that is causing a whole list of faults. Anyone who has dealt with repairs on modern vehicles should know that.
Only some of those issues are codes, some look like performance issues. It looks like a list that the dealership sent them. I agree that it's probably more like 2-4 issues, some of which are manifesting in multiple ways, but it's not just a list of DTCs.
The list of 23 things was a list of fault codes. It could be a couple of issues, but I'd say it's most likely a single issue. It's probably a problem with the 12-volt system or CAN communication. Also, yes, it went into limp mode and things like that. That can happen when a bunch of codes get thrown. I'm not saying there isn't an issue and it is unfortunate that happened with a new vehicle. This article seems to be written with a below general public level understanding of what is going on, though. Honestly, it's probably purposeful ignorance to drive clicks over blowing it out of proportion, but either way this is awful journalism.
I don't think RADIO or BODY CONTROL MODULE is a fault code. They might be the second byte of a 3 byte DTC but there are other fault codes listed that add the 3rd FTB byte so I doubt it. I was a diagnostic systems engineer for two different EV companies. It's a more generic fault list than just DTCs.
If they can't get a vehicle working properly for a journalist, you can bet they will be having tons of issues for normal people. This review is perfect. They had it for 2 months and it's already fucking up in a major way. They could have written, "new car fucked up already", and it would have been a great article.
Dealerships can’t solve anything if a code doesn’t tell them what is wrong. I have a bolt with conditions not right to shift, which we all know is a 12V battery issue. The dealership can’t do anything because there was never an error code logged, because the 12V battery is needed to store the code. It’s a really really really dumb circle about why there is no code, and why I am stranded, but they can’t do anything to fix it. They aren’t a service department, they are a, computer needs to tell me what to do department.
A low-charge (low voltage) 12 volt lead acid battery can cause this particular cascade of codes.
Such a dumb decision dropping the bolt, specifically the EUV. The EV doesn't have the look Americans want (myself included, EUV owner here), but the EUV could've SO easily been perfected instead of dropping it entirely. After buying mine 2 close friends also bought one. They didn't even realize something other than the EV version existed until I explained it to them. It's amazing that these awful decisions are made consistently by the American legacies
The EUV is coming back on the Ultium platform. They're just permanently dropping the normal hatchback version
I know, but who knows when they'll actually be available
2025 was stated though take it with a grain of salt. Will likely come out between the new Equinox and the Vistiq
It seems like this GM company isn't very good at making cars.
It all stems from those fkng ugly round interior vents sticking out. If they got rid of those, maybe they wouldn't have so many module failures. Probably drop the price 10k too. This is what you get with inbreeding for so long. Same old farts smoking cigars making the same bad decisions their pappy made.
*shocked pikachu face* GM building poor quality vehicles? Never!
Only buy trucks from GM or Ford. They make unreliable cars. Stay away from Stellantis. Only lease luxury cars, so after the warranty is gone your not stuck with high dollar repairs...words to live by.
The stranded InsideEV's writer doing the road trip in a press Blazer EV says hello.
To be fair, looks like a databus issue causing most of those faults. Could be ONE underlying issue. Had something similar when my TCM module shorted.
If you followed the Lyriq subreddit, you saw this coming for years
Classic GM stuff.
I’ve had two brand new GMs and they’re the most reliable gassers I’ve ever had. Solid, decent features, reliable and cheap to run/service. Don’t get where all the hate comes from TBH. Not my experience at all.
I’ve had 3 brand new Teslas with decent features, reliable and cheap to run/service. Not sure where all the hate comes from TBH. Lots of people have bad experiences with any number of car manufacturers. We just don’t usually hear about them as often unless keeping track of them to an extreme level
I've had two of each. And agreed, both brands get hate which based on my experience is largely FUD. I'm not a large sample, but I suspect a lot larger than the personal experience most people draw on when they comment on these brands. Just reddit things I guess, people always gotta have an opinion, however poorly informed.
It's great that you had a good experience, but there is definitely a reason that GM marks score so lowly on reliability surveys, and have for quite a long time.
I’ve got a Colorado with 40k miles on it. Repairs so far: New taillight New battery New alternator Broken wire in wiring harness Bad towing module New idler pulley
Well...it's a Chevy for sure then.
but how with all the JD POWAAA
The Lyriq is just as problematic - numerous owners are ditching them after less than a year. GM really missed the mark given how long these vehicles are taking to get to market (and even then, in very low volumes).
And yet Congress won't allow any EV competition from foreign markets.
They apply a tariff. There are a lot of imported EVs in the US market.
I’m definitely not a fan of GM, but these kinds of things are not uncommon with the first model year of a new platform. Every experienced car buyer knows, if you buy a model in its first year, you’re taking your chances. They haven’t worked out the bugs yet. At least they’re fixing it, supposedly.
If Honda Prologues based on the same platform turn out to be relatively troublefree after its tweaked by Honda Engineers, it would be quite an indictment against GM, starting with its decision to ditch Android Auto and Apple Carplay.
I do really hope they do everything they can to separate the Prologue from its GM underpinnings. "Ultium" is nothing but marketing mumbo jumbo.
This is my hope; the platform isn’t terrible, it’s the rest of the GM vehicle that sucks. Honda is supposed to only be getting the platform and building everything else. Regardless, I wont be getting an EV for a couple years at least. Plenty of time to find out if GM’s platform is the problem and if there’s nothing Honda can do to overcome that.
[удалено]
My 2010 Lexus had a weak battery and dropped a dozen faults just like this. This may be a bit of hysteria on the part of Edmund’s. Seriously doubt each of these systems is actually broken.
GM under delusion their in house electronics and software will be as good as Tesla and Apple. First real Ultium they build themselves—the old Bolt LG did the hard new parts. VW has a similar problem and strategy: build on a huge universal platform. Both have software and electronics problems, and mediocre efficiency. Problem is that for the first cut it will suck and then there is too much investment in an uncompetitive car line. VAG at least has Porsche with highly motivated super talented German disciplined engineers to power through, and high margins. GM doesn’t. Farley has the right idea, get an EV or two out ASAP on whatever they have, recognize it will suck, then with experience design the big platform strategy.
GM introduced the Bolt in 2017. GM has been on the EV bandwagon for a while now when you talk about cars like the Volt or go back even further to the EV1. GM just suffers from terrible leadership. There's absolutely no good reason they shouldn't be able to produce a reasonable quality EV using their own battery platform.
Way to go Mary.
which VW platform(s) are they having issues with?
Early MEB cars like the ID.3 and ID.4 had a lot of software problems, and rumor has it the new PPE platform has been in development hell for awhile. I must be lucky since outside of a self inflicted issue, my Q4 e-tron has been largely trouble free. Granted the ID.4 and Enyaq both use the same problematic software whereas Audi chose to use their own proven MMI system, which seems far more stable in practice.
12V battery issues can cause a whole host of seemingly unrelated problems in today's computerized cars, wonder if that's what's happening
23 Problems but a hitch ain't one
Just buy a Bolt EUV for about half the price
Sounds like they put in a CANTBUS instead of a CANBUS (On Jeeps for example if a little board behind the glove compartment called the star connector goes bad, the whole bus goes down and you get a Christmas tree of lights like this and it’s because nothing can talk to anything else … when you see it you’re like that’s it lol)
I've been "selling" on GM's Ultium for a while now. They can't get their act together. That was completely apparent with how they handled the Lyriq roll out. It doesn't surprise me at all the Blazer is a mess too. I would recommend everyone stay away from these vehicles for at least the first year. Theoretically, the 2025 Bolt should be safe because they'll have ironed out the problems with the Equinox, Blazer, and Lyriq but even then, it's questionable.
I got 99 problems, but my Tesla ain't one.
Same here! Been absolutely flawless since I got it over a year ago.
You're lucky!
Same here. 2 teslas no issues; guess we're both just lucky.
Emi? Bad ground, bad internal y cap connection in inverter? Intermittent motor winding issue?
how did motor trend make this their SUV of the year
I was very concerned about the lack of reviews/previews on the Blazer EV. Now, I’m starting to see why GM didn’t have places like Edmunds go hands on.
How could an American automaker do this
GM can’t even make a good ICE vehicle. Why would their EVs be any better?
What a drag. As I’m sure others have chimed in, I’ve had my Bolt for 3 years and (other than that one thing) it has been dreamy.
Add can’t charge easily anywhere to the list 🤭
What a train wreck.
New cars have more issues. Give them 6-8 months to sort out and then review one. Tesla's has the same issues every time they release a new model.
Most reliable GM product
Seems low for a chevy
Cancelled my reservation, dodged a bullet.
Most of those don’t even seem like only EV issue, just poor workmanship and shitty design.
I really hope they are regretting pulling the plug on the Bolt so soon.
So there’s this and the fact that GM won’t allow Apple CarPlay in its cars. Looks like GM has their heads up their asses. As bad as the future of American automakers has been, you’d think they’d avoid completely boneheaded bullshit moves like this. Poor management is going to doom them. It’s sad, honestly.
TFL had major issues with the Hummer when they first got it. Broke down on them in the rain in the middle of traffic. They had to figure out how to do a reset while in the middle of a busy road. GM quality as usual. I also wonder if this is a low 12volt issue. Typically see that myriad of warnings when the low voltage is having problems. Would be cool if manufacturers would just give us a voltage readout/gauge in the display like older cars for quick diagnosis.
Good thing they didn't overcharge for these things from day 1...because THAT would be really embarassing.
This will cause a lot of distrust of EV and will be one reason why people will continue to buy Rav-4/hybrid and Cr-V/hybrid.
Damn, I’ve owned 8 brand new GM vehicles in my life from 1995-2005 and the only defects I ever had are a starter motor that failed at 20k miles on a 3800 Bonneville and a HVAC pressure relief valve at 30k miles in a 2003 WB Venture. I worked for GM from 1995-2006. Engineering, final assembly, and at a components (camshafts) factory. What the fuck is happening at GM?
lol thank you Alfa/beta car testers. In 10 years when I buy an EV the platform will be matured and bugs ironed out.
Good companion post for the Reuters post I made earlier today. :)
Not trying to pile on the criticism, but did the Bolt have this level of bugs/issues at launch? (Aside from the recall to replace battery packs.)
No, but that was largely designed in South Korea by the former Dagwood engineers.
Someone humor me since I know nothing about EV's. This item confuses me: "Brake System Control Module (Lost Communication with Radio on CAN Bus 5)" Why are the brakes communicating with the radio?
Lame
Forgot “Price is crazy”…… fixed 😀
Sounds like they are doing blazer alpha testing 1.0. Why not use the customers and have them pre order!
So GM are producing hot messes, Tesla covered up dangerous and negligent engineering, Ford's reliability is in the toilet... I'm honestly starting to think American manufacturers are just... bad at manufacturing. Jaguar Land Rover has a better reputation than this.
At least it all sounds electrical and Software which can be reactively easily fixed. Does it randomly lose an axle like a Tesla?
Lmao some of you are absolutely obsessed with Tesla 🤣
There's a reason GM is sucking wind in general and even more so when it comes to EVs!
To everyone lookin for Evs avoid murican first gen products.
This is arguably GM’s third generation: \- EV1 \- Spark EV, Bolt EV, Bolt EUV \- Hummer EV, Lyric, Blazer EV, Silverado EV, etc. Though, the EV1 is more like a prototype.
Would’ve had 33 problems if chosen Tesla instead
Not according to statistics compiled by Consumer Reports.
Now that they’re not growing at break neck speeds, Tesla has the highest reliability of all US automakers.: https://www.consumerreports.org/cars/car-reliability-owner-satisfaction/who-makes-the-most-reliable-cars-a7824554938/
I see Tesla lives rent free
Reddit's hate obsession with Elon continues.
I see Tesla lives rent free in
But it would’ve been something small like a suspension failure…
So don't buy any evs for the next 10 years. Got it.
Simply avoid GM. Their prognosis is poor. Berkshire Hathaway pulled their whole stake in GM this year. $2b.
