ENGINE
The bolts holding the exhaust to the catalytic converter broke while I was driving my car. The car could have flipped, the exhaust could have busted through the vehicle, or I could have caused an accident and died. This comes on the heels of the EXACT SAME THING happening to my wife's Chevy Trailblazer with nearly the same mileage as mine. I have 97K miles and she 96K. This is a KNOWN ISSUE to them and it is NOT THE FIRST time this has occurred. There are thousands of similar instances that have occurred and one can easily find the anecdotes through an online search.

ELECTRICAL SYSTEM, UNKNOWN OR OTHER
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.

POWER TRAIN, SEAT BELTS, FORWARD COLLISION AVOIDANCE: WARNINGS
My family and I was I involved in a hit and run accident. My minor child is still suffering from shoulder/rotator cuff injuries. Hewas in the process to start conditioning for football. The seatbelt on the day of the accident did not lock. GM sent a criminal investigator not a trained engineer for the vehicle. The seatbelts needs to be inspected. The motor/transmission is making a ticking sound.

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.

FORWARD COLLISION AVOIDANCE: AUTOMATIC EMERGENCY BRAKING, FORWARD COLLISION AVOIDANCE: WARNINGS, AIR BAGS
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.

ELECTRICAL SYSTEM, POWER TRAIN
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.

SERVICE BRAKES
I reported my first issue back in late 2024 of the brakes squealing they took my car in and resurface the rotors. It stopped squealing for about a few months and now we are in summer of 2025 and they are squealing again. I took my car to the dealership because they told me that my car would be under warranty for 30,000 miles with the brakes. First started when they told me that the guy that told me I would have a rental car waiting for me did not set me up for a rental car. I live 45 minutes to an hour away from the dealership. When I pulled into the garage, I could hear the squealing of my car. When I went up to the counter the guy told me he couldn’t hear anything. They then tried to tell me that I would have to take my car back home and call back in the morning to talk to the rep I was talking to in the service department as he had already left for the day along with his associate. I was determined that I was not leaving there without a rental car and my car to be looked. I finally went in on my own to find the gentleman who sold me the vehicle who I really do appreciate and have no issues with him(Keith Keys) he’s a very good sales person at Weber Chevrolet. As they were getting me a rental the guy from the service department pulled around with my car and asked me to get in. He then told me that he had fixed the issue by slamming on my brakes a few times and that it was OK for me to take it home. I then let him know that it was staying to be looked at and I was going to take the rental. The next day when I called the service rep, he stated that they were going to replace the front brakes and it would be available the following day to pick up. When I went to go pick up my vehicle and leave the parking lot I didn’t even get out of the parking space and it was still squealing. I went back in and they told me it was normal and I would have to call the service rep the following day I’m still waiting to hear. I have owned many Chevy’s to know breaks don’t do that

The turbo went out on the car for absolutely no reason. Message popped up on dash board saying "Engine power reduced". I have seen this happen to many many many other card across the country. It does not many how many miles are on the car. some Ive seen 25k and some ive seen at 60k. Shouldn't Chevy be recalling and fixing the part? Seems unfair to me as a consumer. Who has thousands of dollars to get that repaired?
