2023 Chevrolet Trailblazer

Shift to Park error message when car is already in park and then difficulty getting car to turn off. This is an ongoing issue. I have seen online this is a common problem. This is a safety issue because if the car doesn't turn off the battery will go dead leaving a driver stranded. This issue began soon after the car was out of warranty.

The Onstar module has went out on my car and while researching the issue I found out that it is a very common problem with Chevrolet/GM vehicles years 2021-2025 and although Chevrolet and GM are wwll aware that there's an issue and that the onstar modules are faulty there's been no recall. Mind you the module doesn't just affect onstar features it also is connected to bluetooth microphone and remote start and now none of them work at all.

Screen in car goes black.no radio,no noise,no back up camera-Apple car play won’t hook up anymore-I see others models around mine having exactly the same issues I am experiencing-I have reset radio/screen multiple times,it works anywhere from a few mins to hours then it blacks out again and there is nothing on screen.i have replaced the battery,key fine battery’s,and fuse.and I am still experiencing this issues.i have made an appointment at a Chevy dealer to have it diagnosed March 2,2026.that is $169.00 out of my pocket.again I am seeing plenty of other checks around my make and model having the same issues being recalled. My incident started about January 30,2026.

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.
