“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 ca…”

“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.”

“My vehicle was struck on the left front drivers side while traveling 55 mph. My car flipped multiple times, but when it came to a rest on the drivers side, my head was trapped between the driver's window and the side curtain airbag. I couldn't move the airbag, so I had to move my seat back and bend my neck/head back and down out to get free. My face/head/neck/upper shoulder suffered bruising on the RIGHT SIDE of my body from impact of the airbag. This shouldn't have been the case - the deployment should have impacted the left side of my face. I am in belief that the deployment of this side…”

Fuel/Propulsion System 3

“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.”

“My 2023 Chevrolet Trailblazer is about 3 months old and it’s been making squeaky noises when I break.
