The New Chevy Blazer EV Has Stumbled Twice in Recent Tests - Hard

the new chevy blazer ev has stumbled twice in recent tests hard

General Motors’ fortunes are tied heavily to its new Ultium EV technology. It underpins several existing and upcoming models and is the basis of the automaker’s EV efforts, costing billions of dollars and years of development. A few Ultium-based models have already gone on sale without too many issues, including the GMC Hummer EV and Cadillac Lyriq, but the most recent release hasn’t gone so smoothly. The Chevrolet Blazer EV has recently failed in two high-profile tests by automotive publications, raising questions about its electrical system and software.

Kevin Williams at InsideEVs experienced several issues on his road trip from Ohio to North Carolina, leaving him stranded at a rural charging station. Now, Edmunds is reporting a similar experience, with its almost-new long-term Blazer EV test vehicle recording dozens of errors and weeks in the dealer repair department.

While Williams’ road trip ended with a stranded journalist and a vehicle that couldn’t complete its intended journey, Edmunds’ at least ended in its home area in Southern California. The publication saw eight warning lights during its trip between Los Angeles and San Diego.

Unlike Williams, Edmunds got a 12-volt system error, but both experienced issues charging. Both experiences also unraveled over a short period, but Edmunds recorded 23 issues requiring fixes. The publication sent its SUV to the dealer, where it’s been for more than two weeks so far, requiring support from a GM technician and surrounding stores.

The list of faults is long and won’t be all that interesting for many readers, but there are a few issues to address. The body and drive motor control modules malfunctioned, leaving “lost communication” messages with some windows, while the head-up display experienced a “general electrical malfunction.”

To be fair, this is not only a brand-new vehicle but a brand-new vehicle in a somewhat untested format for GM. People often advise against buying first-generation mobile phones and electronic devices because of the complexity involved with developing an all-new product, so, hopefully, General Motors and Chevy can address these issues with an over-the-air software update to smooth the landing a bit.

This is just in. GM is delaying the Blazer EV due to software issues. We probably won't see the Blazer EV in showrooms until the spring. GM is making Tesla look like Toyota when it comes to reliability. Toyota is getting the last laugh at GM's expense.

Read the new release below.

Nice looking car, too bad. They should have held it back longer and worked all the bugs out. It looks so good I would actually consider one, but...

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.
