2023 Chevrolet Trailblazer

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.

Exhaust fell off under normal operating conditions. Dealership (Dekalb Sycamore Chevrolet- Sycamore Illinois) stated this has been a common issue with this year group of Chevrolet Trailblazer SUVs. Dealership stated the bolts/exhaust pipe junction between the catalytic converter and pipe that goes to the muffler rusts through and the entire exhaust system from the cat back falls out of the undercarriage of the vehicle, which is what happened here.

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.

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 sunroof fabric roll came off of the track when attempting to open the sunroof. Yes it is still off the track I have yet to get it fixed due to time restraints. It poses a risk because of the loud noise it makes until you stop the opening of the sunroof. As many individuals open their sunroof while driving it poses a risk of being a major distraction if and when this happens. I have not taken it to get repaired yet but I did report it to the customer service via the my Chevrolet app. It did not give off any warnings or lights prior to the failure .. it was a sudden failure that shocked me when it occurred as I couldn’t figure out how to stop it to begin with

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. So I did while I was walking to the door a salesman came out and I asked him to open the doors on a 2023 trailblazer setting in front of the store. It had rained earlier that day and we watched water leaking out of all the doors. So I asked him to get a couple more trailblazer keys to other ones on the lot and they all leaked water out of the doors. I spoke to the customer service person and he said another owner of the 2023 trailblazer had came in with the same complaint. I spoke again to the main office of Chevrolet and he told me to come here and file a complaint. Since this is a engineering flaw design. So I am hoping to find out what can be done to fix this issue? And what do I do now?
