2023 CHEVROLET TRAILBLAZER

ENGINE

Coolant Vavle malfunction Engine could overheat Yes Manufacturer No warning lights..check engine light came and I had the car diagnosed

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.

ENGINE

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.

FORWARD COLLISION AVOIDANCE: ADAPTIVE CRUISE CONTROL

The contact owns a 2023 Chevrolet Trailblazer. The contact stated that on several occasions, while the Forward Collision Avoidance: Adaptive Cruise Control was activated, and the brakes were inadvertently activated. The vehicle was taken to a dealer, and it was determined that three software updates needed to be completed. The vehicle was not yet repaired. The manufacturer was notified of the failure, and a complaint was filed. The failure mileage was unknown.

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

ENGINE

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?

My car key keeps getting stuck in the ignition and won’t come out until we unhook the negative on the battery.

Engine failure. “Low engine power” mechanic read code as turbo failure.

ENGINE

The ABS system in this vehicle flashes warnings at quick restarts and while holding the brake down, it has no “sponge” when this happens. The brakes squeal constantly. I’ve had them inspected at every single maintenance and there can be no flaw found. When driving on the interstate, the engine is very “jerky” almost like the transmission can’t keep up with the speed of 70-80mph (not always, but it is noticeable when it happens). At first I didn’t think much of it but with the mass recall of chevys identified, I believe it needs to go on record - particularly about the brakes.

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
