“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.”

“When I start my car my car play will not connect. When I start my car and put my car in reverse to use the back up camera and then put in drive the back up camera will remain on. The speakers are static sometimes. The screen will not work and it will be slow or shut off completely. I have pulled over and shut off my car and opened my door to shut off screen and it remains on for a couple mins playing music even when I shut it off.”

“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. …”
