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?

Bd2 Lexus is just a higher trim package Toyota. ^^
Tassos ONLY consider CIvics or Corollas, in their segment. NO DAMNED Hyundais, Kias, Nissans or esp Mitsus. Not even a Pretend-BMW Mazda. They may look cute but they SUCK.I always recommend Corollas to friends of mine who are not auto enthusiasts, even tho I never owed one, and owned a Civic Hatch 5 speed 1992 for 25 years. MANY follow my advice and are VERY happy. ALmost all are women.friends who believe they are auto enthusiasts would not listen to me anyway, and would never buy a Toyota. They are damned fools, on both counts.
Tassos since Oct 2016 I drive a 2007 E320 Bluetec and since April 2017 also a 2008 E320 Bluetec.Now I am in my summer palace deep in the Eurozone until end October and drive the 2008.Changing the considerable oils (10 quarts synthetic) twice cost me 80 and 70 euros. Same changes in the US on the 2007 cost me $219 at the dealers and $120 at Firestone.Changing the air filter cost 30 Euros, with labor, and there are two such filters (engine and cabin), and changing the fuel filter only 50 euros, while in the US they asked for... $400. You can safely bet I declined and told them what to do with their gold-plated filter. And when I changed it in Europe, I looked at the old one and it was clean as a whistle.A set of Continentals tires, installed etc, 300 EurosI can't remember anything else for the 2008. For the 2007, a brand new set of manual rec'd tires at Discount Tire with free rotations for life used up the $500 allowance the dealer gave me when I bought it (tires only had 5000 miles left on them then)So, as you can see, I spent less than even if I owned a Lexus instead, and probably less than all these poor devils here that brag about their alleged low cost Datsun-Mitsus and Hyundai-Kias.And that's THETRUTHABOUTCARS. My Cars,
NJRide These are the Q1 Luxury division salesAudi 44,226Acura 30,373BMW 84,475Genesis 14,777Mercedes 66,000Lexus 78,471Infiniti 13,904Volvo 30,000*Tesla (maybe not luxury but relevant): 125,000?Lincoln 24,894Cadillac 35,451So Cadillac is now stuck as a second-tier player with names like Volvo. Even German 3rd wheel Audi is outselling them. Where to gain sales?Surprisingly a decline of Tesla could boost Cadillac EVs. Tesla sort of is now in the old Buick-Mercury upper middle of the market. If lets say the market stays the same, but another 15-20% leave Tesla I could see some going for a Caddy EV or hybrid, but is the division ready to meet them?In terms of the mainstream luxury brands, Lexus is probably a better benchmark than BMW. Lexus is basically doing a modern interpretation of what Cadillac/upscale Olds/Buick used to completely dominate. But Lexus' only downfall is the lack of emotion, something Cadillac at least used to be good at. The Escalade still has far more styling and brand ID than most of Lexus. So match Lexus' quality but out-do them on comfort and styling. Yes a lot of Lexus buyers may be Toyota or import loyal but there are a lot who are former GM buyers who would "come home" for a better product.In fact, that by and large is the Big 3's problem. In the 80s and 90s they would try to win back "import intenders" and this at least slowed the market share erosion. I feel like around 2000 they gave this up and resorted to a ton of gimmicks before the bankruptcies. So they have dropped from 66% to 37% of the market in a quarter century. Sure they have scaled down their presence and for the last 14 years preserved profit. But in the largest, most prosperous market in the world they are not leading. I mean who would think the Koreans could take almost 10% of the market? But they did because they built and structured products people wanted. (I also think the excess reliance on overseas assembly by the Big 3 hurts them vs more import brands building in US). But the domestics should really be at 60% of their home market and the fact that they are not speaks volumes. Cadillac should not be losing 2-1 to Lexus and BMW.
Tassos Not my favorite Eldorados. Too much cowbell (fins), the gauges look poor for such an expensive car, the interior has too many shiny bits but does not scream "flagship luxury", and the white on red leather or whatever is rather loud for this car, while it might work in a Corvette. But do not despair, a couple more years and the exterior designs (at least) will sober up, the cowbells will be more discreet and the long, low and wide 60s designs are not far away. If only the interiors would be fit for the price point, and especially a few acres of real wood that also looked real.
