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.

  • El scotto No rag-top, no rag-top(s) = not a prestigious car brand. Think it through. All of the high-end Germans and Lexus have rag-tops. Corvette is really its own brand.World-leading engines. AMG, M, S and well Lexus is third-world tough. GM makes one of the best V-8s in the world in Bowling Green. But nooooo, noooo, we're GM only Corvettes get Corvette engines. Balderdash! I say. Put Corvette engines in the top-tier Cadillacs. I know GM could make a world-class 3.5 liter V-6 but they don't or won't. In the interior everything that gets touched, including your butt, has to feel good. No exceptions.Some think that those who pay above MSRP and brag about it are idiots. Go the opposite direction, and offer an extended 10-year 100,000-mile factory warranty. At a reasonable price. That's Acura's current business model.
  • Carrera 2014 Toyota Corolla with 192,000 miles bought new. Oil changes every 5,000 miles, 1 coolant flush, and a bunch of air filters and in cabin air filters, and wipers. On my 4th set of tires.Original brake pads ( manual transmission), original spark plugs. Nothing else...it's a Toyota. Did most of oil changes either free at Toyota or myself. Also 3 batteries.2022 Acura TLX A-Spec AWD 13,000 miles now but bought new.Two oil changes...2006 Hyundai Elantra gifted from a colleague with 318,000 when I got it, and 335,000 now. It needed some TLC. A set of cheap Chinese tires ($275), AC compressor, evaporator, expansion valve package ( $290) , two TYC headlights $120, one battery ( $95), two oil changes, air filters, Denso alternator ( $185), coolant, and labor for AC job ( $200).
  • Mike-NB2 This is a mostly uninformed vote, but I'll go with the Mazda 3 too.I haven't driven a new Civic, so I can't say anything about it, but two weeks ago I had a 2023 Corolla as a rental. While I can understand why so many people buy these, I was surprised at how bad the CVT is. Many rentals I've driven have a CVT and while I know it has one and can tell, they aren't usually too bad. I'd never own a car with a CVT, but I can live with one as a rental. But the Corolla's CVT was terrible. It was like it screamed "CVT!" the whole time. On the highway with cruise control on, I could feel it adjusting to track the set speed. Passing on the highway (two-lane) was risky. The engine isn't under-powered, but the CVT makes it seem that way.A minor complaint is about the steering. It's waaaay over-assisted. At low speeds, it's like a 70s LTD with one-finger effort. Maybe that's deliberate though, given the Corolla's demographic.
  • Mike-NB2 2019 Ranger - 30,000 miles / 50,000 km. Nothing but oil changes. Original tires are being replaced a week from Wednesday. (Not all that mileage is on the original A/S tires. I put dedicated winter rims/tires on it every winter.)2024 - Golf R - 1700 miles / 2800 km. Not really broken in yet. Nothing but gas in the tank.
  • SaulTigh I've got a 2014 F150 with 87K on the clock and have spent exactly $4,180.77 in maintenance and repairs in that time. That's pretty hard to beat.Hard to say on my 2019 Mercedes, because I prepaid for three years of service (B,A,B) and am getting the last of those at the end of the month. Did just drop $1,700 on new Michelins for it at Tire Rack. Tires for the F150 late last year were under $700, so I'd say the Benz is roughly 2 to 3 times as pricy for anything over the Ford.I have the F150 serviced at a large independent shop, the Benz at the dealership.
