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.

  • 28-Cars-Later Used Teslas are getting very cheap, but buying one can be risky - Ars Technica Teslas are very connected cars, and many of their convenience features are accessed via smartphone apps. But that requires that Tesla's database shows you as the car's owner, and there are plenty of reports online that transferring ownership from Hertz can take time.Unfortunately, this also leaves the car stuck in Chill driving mode (which restricts power, acceleration, and top speed) and places some car settings outside of the new owner's level of access. You also won't be able to use Tesla Superchargers while the car still shows up as belonging to Hertz. Based on forum reports, contacting Tesla directly is the way to resolve this, but it can take several days to process; longer if there's a paperwork mismatch.Once you've transferred ownership to Tesla's satisfaction, it's time to do a software reset on the car to remove the fleet version.So apparently the state maintains title but so does Tesla in a way, and they cripple some features until they feel satisfied in unlocking them to you. How long till they brick it by satellite because, reasons? But yes, rah! rah! BEV! - its not a tool of tyranny at all, honest. Edit: Comment from the Ars forum: Happy MediumArs Tribunus Militum 19y When I got to the section that stated that THE CAR WILL BE FUNCTIONALLY CRIPPLED unless you get Tesla's acceptance of you buying the car, I got incredibly infuriated. How in the hell is this going to work going forwards? Is Tesla literally going to be approving every single resale of its cars from now until the car is totaled? Jeezus, connected is one thing, but having final ownership authority in the hands of the manufacturer and not the seller/purchaser seems horrible. 28's thoughts to Happy Medium.
  • Tane94 Subie has a cult-like devotion to its products, so it can do no wrong by being a late adopter in offering EVs. Mazda has rebranded itself from zoom zoom to affordable near luxury, with success. Toyota is most vulnerable to losing sales from not having EVs. The hybrid early adopters who made Prius their high-visibility flag bearer now have to look to another brand for a distinctive EV to righteously show themselves off.
  • Jrhurren The EV haters would keep complaining until prices hit $0, at which point they would proceed to complain some more.
  • Kwik_Shift_Pro4X Remember the Mitsubishi Pajero? 😆
  • Macca Judging by the atrocious reliability record and general lemony snicket nature of the ICE Wagoneer and GC, this makes about as much sense as the electrically-challenged Brit marques going EV. Upper trim interiors on the GW & GC are a case of 'nice at 10 paces' (or glammed up press photos). In person there are low-rent plastics throughout at critical touch points (center tunnel, seat & mirror controls on the door panel, for instance) where there is unnerving flex akin to a toy. Adding more screens when the main Uconnect screen is already flaky doesn't bode well.
