A loud popping noise heard through the radio when light pressure applied to brakes. Noise loud enough to scare the hell out of all the occupants in the car. Brakes squeaked when car was in reverse. Tried to slow down on wet pavement. Car started to veer to the right. Forward collision warning nor automatic emergency braking worked. Pushed brake all the way to the floor and the car did not slow. Rear ended another car. No airbags deployed. My passenger was okay. I got diagnosed with a concussion. Do not know if the occupants in the other car were injured.
Brakes failed and myself and others were in harms way. To my knowledge the car was totaled as the air bags did deploy.

The contact owns a 2021 Chevrolet Trailblazer. The contact stated while driving 65 MPH the contact struck a deer on the front passenger side causing minor damages to the vehicle. No one was injured. The contact was able to stop on the side of the road. The contact smelled a burning odor and noticed that smoke was coming from the floor of the vehicle on the front passenger side near the seat belt assembly. The contact and the passenger were able to exit the vehicle, but after exiting the vehicle burst out in flames. The fire department was able to extinguish the fire. A police report was filed.

Was in the middle of a 3 car collision. After about 5 min engine started smoking and a fire started. Fire slowly escalated and fully engulfed the entire car.
Driving vehicle and noticed smoke coming from front end. Pulled over and entire vehicle caught fire. No check engine light, no temp gauge changes. Just smoke and then fire.
While traveling down the road at approximatly 35-40 mph with my two minor children, the steering was not responding properly and the car kept attempting to veer to the right. I let off the gas to slow down since the brakes were also not seeming to respond well. Upon attempting to brake and execute a left hand turn, the car would not turn at all despite the steering wheel being as turned as far to the left as possible, the lights began flashing on the dashboard for "PowerSteering" ESC warning. We ended up going through the intersection without stopping and narrowly missed another car in intersection and went completely off the road into a snowbank. Fortunately we were not injured. We drove the vehicle back home (approximately one mile) by overpowering the steering and manually forcing the car to stay on the road. Throughout the lane assist kept attempting to autocorrect and drive us off the road. The car was damaged by the impact and the mechanic said that the tie rod is bent and has no idea what could have caused this to happen. I am somehow now responsible for the situation. I have asked what caused the power steering to fail, and Chevy claims that they have no record of any power steering issues (which research has shown to be untrue) and in order to determine IF it failed and/or why, they need to make the repair and then run additional tests to re-create the issue. This car only has 21,000 miles on it, and has never been in an accident before this.
Someone pulled out in front of me going 45 mph and totaled my car when they smashed into the front drivers side of my vehicle. My airbags didn’t deploy and no warning notifications or emergency braking ever occurred. This is dangerous and was severe enough to total my vehicle. My airbags should have deployed. No warning lights or any other issues when it occurred. It was inspected by insurance and determined a total loss.
Dear Chevy, I am reaching out to you again because I am desperately requesting immediate assistance with my vehicle, which has now become an extremely serious and dangerous safety concern. On Friday, [XXX], I had my vehicle towed to the dealership because of the ongoing mechanical issues I have been experiencing. I was advised that the repairs would cost 877, which included a battery replacement and new sensors. I paid for these repairs and picked up my vehicle on Wednesday, September 2, 2026, believing that the issues had finally been addressed. Unfortunately, within approximately one hour of leaving the dealership, my check engine light came back on. When I arrived home, the key became stuck in the ignition. I immediately contacted the dealership and requested to speak with a Service Manager. I made this request approximately five separate times, yet I was unable to speak with a Service Manager until Friday, September 4, 2026, when I finally spoke with Matt. The situation has now escalated into an extremely dangerous and potentially life-threatening safety issue. On Sunday, [XXX], while driving on the [XXX] in Chicago, my vehicle completely shut off twice while I was actively driving. There were no warning sounds, no dashboard warning codes, and no indication that the vehicle was about to shut off. My vehicle suddenly lost power while I was on a busy expressway, creating an extremely dangerous situation and nearly causing a major accident/pileup. I genuinely feared for my life. A vehicle that unexpectedly shuts off while traveling at highway speeds is not something I can safely continue driving. After this occurred, I had the vehicle towed to my home. I later attempted to start it, and the vehicle did start; however, the key became stuck in the ignition again. This problem has been ongoing for over a year, and I have repeatedly and desperately asked for these issues to be properly diagnosed and repaired. I have already INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)
Original Owner of 2021 Chevy Trailblazer LT. Purchased new in April 2021. Vehicle has a history of major powertrain issues, starting with Check Engine light during its first year of ownership, culminating in a complete turbocharger replacement in December 2025. This only as a result of my research, after many visits to dealership trying to diagnose the issue. The check engine was consistently illuminated in the vehicle 2021-2025. 9 days ago while traveling the vehicle, experienced sudden oil pressure loss, and stalling risks, displayed a hard warning “ENGINE OIL PRESSURE LOW. STOP ENGINE”. On Star provided me with a diagnostic code of P0521, pointing to an engine oil pressure sensor malfunction. Apparently another widely known issue with this engine, there are TSBs stating after repair the code will return and Software Update required. Extended warranty has expired, dealership as well as GM corporate unwilling to provide any assistance with cost of diag, repairs, etc, leaving myself and disabled dependent stranded. Vehicle since purchase has been exclusively serviced through the purchasing dealerships service center. Maintenance regularly maintained. Service management has admitted knowledge of this issue with this engine, still reluctant to provide any additional assistance, informed me I’m on a waitlist for a possible loaner vehicle 4-6 weeks from now. There are several TSBs on this engine surrounding this issue. Apparently there is a known defect with the engine oil pump, cam shaft, evap purge pump. Strong possibility could be a result of the Turbo replacement, debris from that failing turbo could have blocked the oil system, causing starvation.
My timing belt snapped prematurely, causing a total loss of engine power while driving on the highway, which is a severe safety hazard
I am submitting this report regarding my 2021 Chevrolet Trailblazer because it has been experiencing the "Shift to Park" issue described in the GM bulletin 19-NA-206. Even when the vehicle is shifted into Park, it intermittently displays a "Shift to Park" message and does not recognize that the transmission is in Park. This issue has been ongoing and has not resolved despite normal use of the vehicle. It is frustrating to deal with on a regular basis, and it appears to be the same condition addressed by GM in Technical Service Bulletin 19-NA-206 that is available to view on the NHTSA website. I believe the NHTSA should push General Motors to issue a recall for this problem rather than relying on a Technical Service Bulletin. The issue appears to affect many GM vehicles, and owners should not have to bear the burden of repeated repairs or diagnosis for a known defect. I respectfully request that the NHTSA investigate this issue further and require GM to provide a permanent remedy through a recall.
"shift to park" issue on a 21 traiblazer causing your car to not being able to shutdown entirely meanwhile the shift is perfectly on Park.
Vehicle displays Shift to Park when vehicle is in park & you push the ignition button & audible chime occurs. Apparently this is a known issue for Chevrolet Trailblazers & Buick Encore GX vehicles model year 2021 & newer. You have to either wiggle the gear shifter several times & depress/wiggle the shift lever button in order to turn off the vehicle. Sometimes it takes 5 minutes to get it to work.
