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.

  • Jalop1991 Our MaintenanceCosts has been a smug know-it-all.
  • MaintenanceCosts If I were shopping in this segment it would be for one of two reasons, each of which would drive a specific answer.Door 1: I all of a sudden have both a megacommute and a big salary cut and need to absolutely minimize TCO. Answer: base Corolla Hybrid. (Although in this scenario the cheapest thing would probably be to keep our already-paid-for Bolt and somehow live with one car.)Door 2: I need to use my toy car to commute, because we move somewhere where I can't do it on the bike, and don't want to rely on an old BMW every morning or pay the ensuing maintenance costs™. Answer: Civic Si. (Although if this scenario really happened to me it would probably be an up-trimmed Civic Si, aka a base manual Acura Integra.)
  • El scotto Mobile homes are built using a great deal of industrial grade glues. As a former trailer-lord I know they can out gas for years. Mobile homes and leased Kias/Sentras may be responsible for some of the responses in here.
  • El scotto Bah to all the worrywarts. A perfect used car for a young lady living near the ocean. "Atlantic Avenue" and "twisty's" are rarely used in the same sentence. Better than the Jeep she really wants.
  • 3-On-The-Tree I’ll take a naturally aspirated car because turbos are potential maintenance headaches. Expensive to fix and extra wear, heat, pressure on the engine. Currently have a 2010 Corolla and it is easy to work on, just changed the alternator an it didn’t require any special tools an lots of room.
