Chevrolet
Trailblazer

I was in a collision. Traveling a four lane highway during daylight ours with no in-climate weather. The car in front of a line of approximately 4 cars missed their exit and slammed on his breaks to make a right turn from the driving lane. The line of cars in front of me stopped and/or left the roadway to avoid a collision. I was unable to stop in time and had nowhere to go and I rear-ended the car in front of me, which was fully stopped in the lane. According to my dash camera my speed on Impact was approximately 45 mph. No front end collision warning alarms went off. No automatic breaking occurred. No airbag deployed. None of the vehicle safety and anti collision measures performed as I had expected. $10,000 worth of damage to my car alone.

1/ while at the stop site, the car suddenly stopped and went black. Stereo turn off and screen went black. 2/ sometime I can’t unlock the car from inside. The lock works but not the unlock button. While backing or stopping there is a high noise that seems like I have a bad brake , took it to the dealership and they said the brake is good but they can’t figure out where the noise coming from. I took the car to the dealership 3 times in 1 month since the problem started and they still can not fix it.

When I shift my vehicle into park and hit the button to shut it off, a "shift to park" message appears on the DIC screen. I then am required to start my vehicle again, shift into gear, and then put it back into park and attempt to shut the vehicle off again. It has taken me up to 15 minutes to be able to get it to recognize that my vehicle is in park and for the message to not pop up. If I get out of the car while the message is still on the DIC screen, I cannot lock my vehicle and it drains the battery. I contacted my local Chevrolet dealer and they are saying that although this is a known issue which has had more than one GM Service Bulletin on this issue which includes my year and model, there is not an actual recall for this, so I have to pay out of pocket, because my bumper to bumper warranty expired at 36,000 miles and I am currently just shy of 39,000 miles. Of note, there is also a class action lawsuit for this exact issue so I am confused as to why a recall would not have been issued, or why it would not still be covered despite the expired bumper to bumper warranty.

Onstar module that is supposed to working in case of a crash or another emergency stopped working back in November 2024. It also is attached to other operations such as the vehicles microphone. I took it to the dealership Chevrolet said they would pay half of the replacement. My vehicle is not the only one. There is a forum online and other GM vehicles are having the same issue.

at around 42,000 miles my Trailblazer displayed a message that engine power had been reduced and the check engine light came on. I took it to my dealer who diagnosed as a problem with the engine turbo fixed it and returned the car to me. I drove for 2 weeks and the same thing happened. I traded it in on an Equinox after the service manager said the turbo was a know issued. I did not want to be driving on the interstate with reduced power. Also I took a financial hit on the trade.
