2024 Chevrolet Trailblazer

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.

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. They are not sure what is causing the issue, but on 05/24/2025 I was attempting to get ready to get gas and needed to pull up slightly a little bit more and when I shifted to drive my car jolted forward and hit another vehicle. No damage was done to the other vehicle or mine, and the gentleman was nice and said it caused no damage for either of us but my car cannot keep doing this. Sometime is not right with it to be constantly jolting forward as soon as I shift to drive and take my foot off the break peddle to go. This could have been a lot worse had a human been in front of me and I do not want that to ever happen.

My daughter was stopped at a stoplight and the auto-stop engaged. The light turned green and she began to accelerate when all of the error lights on the dash lit up, then the dash info system and infotainment system went out followed by the engine turning off and not restarting. While all of this happened, the vehicle behind me struck my daughter’s car. Luckily it was at a low rate of speed and no one was injured. I took the car to the dealer and after nearly a week of testing they found nothing wrong and found no error codes in the system. They ere not able to replicate the problem. However, once we got the vehicle back a similar instance happed again, except just the dash info system and infotainment system went out and the car was still drivable. Once restarted the electronics came back on as normal. It has not happened again at this point. Had the first incident happened at a higher rate of speed a severe injury or fatality could have occurred.

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. I was able to contact AAA, and after a "jump", it started. However, because of my proximity to the highway, I opted to have it towed to the dealer where I bought it....they ran service on it and can find nothing wrong with it...as you can imagine, I am nervous to drive on the highway (which I do 5 days a week normally)...

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.
