Stop-Sale Issued for 2024 Chevy Blazer EV

General Motors has issued a stop-sale order for the all-electric Chevrolet Blazer. As previously reported, the model has been criticized for presenting reviewers with electrical problems. That’s not what you want to see from any vehicle and absolutely intolerable on an EV. Even worse is the fact that the Blazer EV uses the Ultium platform GM claims is about to underpin its future lineup.


The automaker is telling dealers to pause sales so it can address problems with charging and the infotainment system. However, the solution seems to be the obligatory “software update” every company leads off with when it’s looking like recall time.


As of yet, no formal recall has been announced. But General Motors claims it has teams working 24/7 to address the issue. It’s also trying to downplay the problems as much as possible, referencing concerns as limited in number and suggesting they have nothing to do with the new Ultium battery platform or the infotainment system's built-in Google tech.


Considering how much GM has invested into Ultium as it pivots toward all-electric powertrains, this isn’t surprising. It also needs to be said that businesses trying to pioneer any new technology tends to come with some unpleasant growing pains. But General Motors is already putting these vehicles on the road and reviewers have noticed Ultium products suffering more than usual. The Fast Lane Truck noted electrical problems with the GMC Hummer that made it un-drivable, requiring help from the dealership and a software flash. Meanwhile, both Edmunds and InsideEVs recounted similar problems with the Chevy Blazer EV.


Automotive News reported the stop-sale order was issued late on Friday, when people would be preoccupied with the holiday weekend. "We're aware that a limited number of customers have experienced software-related quality issues with their Blazer EV. Customer satisfaction is our priority and as such, we will take a brief pause on new deliveries,” stated Global VP of Chevrolet Scott Bell.


Those “quality issues” included repeat crashing of infotainment systems and problems charging. InsideEVs said it received feedback from readers claiming that they had likewise endured issues with Ultium-based products — including the Chevrolet Blazer EV, GMC Hummer, and Cadillac Lyriq.

“[Three days later,] we took it to the dealer. No one seemed to know what to do," wrote Andrew Kozar, who noticed his Blazer EV acting up after just five days of ownership. "After two weeks a tech was finally able to reproduce the issue (after some insistent prodding from myself with picture proof I was not making it up.) They decided to do a software update that bricked both the infotainment system AND gauge cluster rendering it useless. Because no speedometer means to driving. We are currently waiting on a replacement module and on week three of the dealer having my car. I was lucky enough to drive it five days issue-free."


Considering how reliant modern vehicles are on touchscreens, having one go out typically means that’s it until the vehicle can be repaired. But the Blazer EVs were said to be throwing out all sorts of codes indicating that various on-board systems were having trouble communicating with one another. Mr. Kozar even stated that the radio module his dealership installed as part of the infotainment fix wouldn’t interface with the rest of the vehicle, leaving technicians bewildered.


Charging errors have also been reported when customers have attempted DC fast charging, with InsideEVs noting that GM and Electrify America are both still working on figuring out what happened with its Blazer test vehicle. Nobody seems to have any answers yet, with some customers suggesting that dealerships don’t seem to know what to do with the vehicles. Many of the fixes have also resulted in Ultium vehicles simply charging extremely slowly, regardless of what they’re plugged into.


As of now, there are only a few thousand Ultium products on the road and most appear to be fully functional. However, it would be untrue to say that the frequency of the above problems isn’t a little alarming. You don’t normally see multiple reviewers have cars unravel like this during testing. While your author has been in situations where an infotainment screens become suddenly unresponsive or a surprise warning light appears, those instances are incredibly rare and never result in the vehicle becoming totally un-drivable.


General Motors seems to believe that the Blazer EV just needs some new code. But it apparently cannot do this via over-the-air (OTA) updates. Customers will have to bring their electric vehicle to dealer service centers for the hands-on approach.

    And this is the reason that no matter how much technology progresses, the adage “never buy the first model year of anything unless you’re willing to deal with issues” will never change.

    How's the resale value on a 7 year old LG?

  • Theflyersfan I used to love the 7-series. One of those aspirational luxury cars. And then I parked right next to one of the new ones just over the weekend. And that love went away. Honestly, if this is what the Chinese market thinks is luxury, let them have it. Because, and I'll be reserved here, this is one butt-ugly, mutha f'n, unholy trainwreck of a design. There has to be an excellent car under all of the grotesque and overdone bodywork. What were they thinking? Luxury is a feeling. It's the soft leather seats. It's the solid door thunk. It's groundbreaking engineering (that hopefully holds up.) It's a presence that oozes "I have arrived," not screaming "LOOK AT ME EVERYONE!!!" The latter is the yahoo who just won $1,000,000 off of a scratch-off and blows it on extra chrome and a dozen light bars on a new F150. It isn't six feet of screens, a dozen suspension settings that don't feel right, and no steering feel. It also isn't a design that is going to be so dated looking in five years that no one is going to want to touch it. Didn't BMW learn anything from the Bangle-butt backlash of 2002?
  • Theflyersfan Honda, Toyota, Nissan, Hyundai, and Kia still don't seem to have a problem moving sedans off of the lot. I also see more than a few new 3-series, C-classes and A4s as well showing the Germans can sell the expensive ones. Sales might be down compared to 10-15 years ago, but hundreds of thousands of sales in the US alone isn't anything to sneeze at. What we've had is the thinning of the herd. The crap sedans have exited stage left. And GM has let the Malibu sit and rot on the vine for so long that this was bound to happen. And it bears repeating - auto trends go in cycles. Many times the cars purchased by the next generation aren't the ones their parents and grandparents bought. Who's to say that in 10 years, CUVs are going to be seen at that generation's minivans and no one wants to touch them? The Japanese and Koreans will welcome those buyers back to their full lineups while GM, Ford, and whatever remains of what was Chrysler/Dodge will be back in front of Congress pleading poverty.

  • Turbo Is Black Magic My wife had one of these back in 06, did a ton of work to it… supercharger, full exhaust, full suspension.. it was a blast to drive even though it was still hilariously slow. Great for drive in nights, open the hatch fold the seats flat and just relax.Also this thing is a great example of how far we have come in crash safety even since just 2005… go look at these old crash tests now and I cringe at what a modern electric tank would do to this thing.
  • MaintenanceCosts Whenever the topic of the xB comes up…Me: "The style is fun. The combination of the box shape and the aggressive detailing is very JDM."Wife: "Those are ghetto."Me: "They're smaller than a Corolla outside and have the space of a RAV4 inside."Wife: "Those are ghetto."Me: "They're kind of fun to drive with a stick."Wife: "Those are ghetto."It's one of a few cars (including its fellow box, the Ford Flex) on which we will just never see eye to eye.
