“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.”

“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.”

“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.”

“I purchased a 2023 trailblazer in February. And had noticed that the doors hold water in the front of the doors. After a rain or car washing the doors will drain when opened. But after a rain or washing and you leave the doors closed even a couple days later then open the doors water will drain out of each front hole on each door. I took it back to the dealership and the washed it and said that the doors drain while they are open. So I contacted Chevrolet main office and they asked me to take it back to the dealership. …”
