Example complaints
Selected from NHTSA records; personal details are removed. They are consumer reports, not findings.
“Almost every time I shift from park to drive and take my foot off the brake my car jolts forward a couple feet/inches to take off by itself in a manner that it should not. This has been going on since I got the car brand new and have had it just over a little over a year. I try to be as careful as I can with it and mentioned it to the Chevrolet dealership that does all my maintenance on my car. …”
NHTSA complaint #11662986, filed 2025-05“My 2024 Chevrolet Trailblazer ACTIV with 26,000 experienced complete engine failure while driving. Palm Chevrolet said my Trailblazer had “internal engine failure” and needs to be replaced.”
NHTSA complaint #11662994, filed 2025-05“My 2024 trailblazer lt's engine light came on about a month ago. I took it to a local dealership and they said it was caused by CCND. Diagnosed code P0128 in pass/fail status. They test drove it to get light to come on and it was unable to duplicate it. They cleared the codes. A month later it came back on. I took it to my dealership and they said they have to take the entire front end off to replace the engine coolant bypass valve. They said that the electronic component was going bad. This car isn't even 2 yrs old. This should not be happening.”
NHTSA complaint #11711444, filed 2026-01“I was driving my 1 week old vehicle, on a city street, foot still on the gas, and the vehicle COMPLETELY shut down; no power at all. it wasn't the auto start/stop technology, but rather a complete power down. no lights, no hazard lights, no dash, nothing worked. The car came to an abrupt stop. The gear shift could not be moved into neutral, nothing. Luckily I was on a city street with not a lot of traffic. If I had been on a highway it could have caused a SERIOUS accident; if I had been driving across railroad tracks and it stops - very dangerous. …”
NHTSA complaint #11619009, filed 2024-10“While in traffic, brand new 2024 Chevy Trailblazer vehicle has stalled on us a few times now and doesn't start right back up. It appears to happen when the vehicle is going from the fuel saving start-stop mode and we've found ourselves in a precarious situtations in traffic. I can foresee this happening at a very dangerous time causing a bad wreck. We just dropped the vehicle off with the dealer as we've had other issues with safety deterrent system going off for no reason and other pop ups on the instrument panel. However, the stalling in the middle of traffic is my worst concern.”
