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.

  • Ras815 It's a travesty that this is even allowed to carry the same 7er identity that the E23, E32 and E38 established.
  • V16 It's hard to believe that GM or Ford in 2024 can't or won't design a truly class leading sedan for the North American market.To cede the entire mainstream market to Japan and Korea is an embarrassment.
  • 1995 SC I don't know what the answer is, but out Germaning the Germans hasn't been it. Look at what works and do that (Escalade?). Maybe the world is ready for an option that just sort of shuts the world out at the end of the day and gives the driver a nice, supple ride home and is suited to the world that most people drive in.They won't though. The Journos will hate it and cry about ring times and at the end of the day that and dealers are who the cars are built for...not you. And Cadillac will likely fail sadly.
  • Daniel I couldn't agree more! As someone who is literally 100% brand agnostic, Cadillac is right up there with Lincoln for (relatively) very nice American brand designs and powetrains (OK, their sedans are getting a little stale with the same pointy, CyberTruck angles, but I digress) but their interiors really are absolutely lacking almost *any* differentiation from the "solid for what it is" Chevy parts bin and deserves better!
  • Fred Do what GM wants, cut costs. Pull out of racing hyper cars, defund the F1 program. Finally make more SUVs.
