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.

  • Peter Buying an EV from Toyota is like buying a Bible from Donald Trump. Don’t be surprised if some very important parts are left out.
  • Sheila I have a 2016 Kia Sorento that just threw a rod out of the engine case. Filed a claim for new engine and was denied…..due to a loop hole that was included in the Class Action Engine Settlement so Hyundai and Kia would be able to deny a large percentage of cars with prematurely failed engines. It’s called the KSDS Improvement Campaign. Ever hear of such a thing? It’s not even a Recall, although they know these engines are very dangerous. As unknowing consumers load themselves and kids in them everyday. Are their any new Class Action Lawsuits that anyone knows of?
  • Alan Well, it will take 30 years to fix Nissan up after the Renault Alliance reduced Nissan to a paltry mess.I think Nissan will eventually improve.
  • Alan This will be overpriced for what it offers.I think the "Western" auto manufacturers rip off the consumer with the Thai and Chinese made vehicles.A Chinese made Model 3 in Australia is over $70k AUD(for 1995 $45k USD) which is far more expensive than a similar Chinesium EV of equal or better quality and loaded with goodies.Chinese pickups are $20k to $30k cheaper than Thai built pickups from Ford and the Japanese brands. Who's ripping who off?
  • Alan Years ago Jack Baruth held a "competition" for a piece from the B&B on the oddest pickup story (or something like that). I think 5 people were awarded the prizes.I never received mine, something about being in Australia. If TTAC is global how do you offer prizes to those overseas or are we omitted on the sly from competing?In the end I lost significant respect for Baruth.
