2021 Chevrolet Trailblazer Complaint Log

On June 10, 2021 I was driving home at a speed of approx 65 miles an hour from the grocery store on Interstate 255 when all my side airbags suddenly exploded. My 2021 Chevy Trailblazer RS was 3 months old and had 3500 miles on the car. After exiting the vehicle, I found the rear passenger tire was flat. Upon changing the tire, we discovered that the wheel had split apart. There is no damage to the body or underneath the vehicle. There was no large potholes or debris anywhere in the area. Upon starting the investigation with GM regarding the incident, they reported that the air bags acted as they should and they would not take liability. When both myself and the service manager of the dealership questioned why the report had not one single mention of the tire/wheel which caused the deployment of the airbags in the entire investigative report, we were both told "the airbags acted as they should" and the decision was final. The service manager was in shock and has stated repeatedly that based on the facts gathered and condition of the tire/wheel, there was some sort of defect in the wheel which caused it to explode. There is absolutely no evidence to make him think that I hit anything or caused the incident. GM will not discuss the case any further and told me to turn it over to my insurance. The fact that they did not investigate the cause (the exploding of a wheel for no apparent reason) makes me believe they are trying to cover up a potential issue that could impact the safety of other 2021 Trailblazer owners. The air bag replacements are on backorder and are predicted to take months. I am currently without a vehicle.

I WAS DRIVING MY BRAND NEW 2021 TRAILBLAZER (ONLY 160 MILES) AND STEPPED ON THE BRAKE TO STOP AT THE END OF A STREET. SUDDENLY, I GOT ALERTS THAT MY BRAKE SYSTEM HAD FAILED AND RIGHT AFTER THAT, ANOTHER ONE, SAYING THAT THE POWER STEERING NEEDED TO BE SERVICED. AT THAT POINT, IT REQUIRED MUCH MORE PRESSURE ON THE BRAKE TO STOP, AND THE BRAKES DIDN'T SEEM VERY RESPONSIVE. LATER I SHUT OFF THE ENGINE, AND WHEN I STARTED IT AGAIN, THE CHECK ENGINE LIGHT WAS STILL ON, BUT I THINK THE BRAKES WERE WORKING AGAIN. I'M NOT SURE BECAUSE I DIDN'T WANT TO DRIVE IT, JUST IN CASE.

TWO TIMES I HAVE HEARD A LOUD POP NOISE COMING THROUGH MY STEREO SPEAKERS. I NOTICED IT WHEN APPLYING THE BRAKES. I WENT ON A TRAILBLAZER FORUM AND A FEW OTHERS HAD REPORTED THE SAME THING. I HEARD THE POP TODAY WHEN I WAS PULLING INTO A PARKING SPOT AND APPLYING THE BRAKES.

The contact owns a 2021 Chevrolet Trailblazer. The contact stated that while driving at various speeds, the vehicle made an abnormal popping sound before the power steering and brakes failed. Additionally, the brake pedal became extremely sensitive while gently being depressed causing the vehicle to abruptly stop. The contact had to restart the vehicle to correct the failure. The failure was intermittent. The vehicle was taken to the dealer however, the dealer could not duplicate the failure. The vehicle was taken to another dealer, Frontier Motors Incorporated (31406 US-18, Winner, SD 57580) on numerous occasions and diagnosed with electrical system failure. The dealer reprogrammed the power steering angle sensor and rear differential clutch sensor; however, the failure recurred. The vehicle was not repaired and remained at the dealer. The manufacturer was made aware of the failure. A case was being processed by the Better Business Bureau under the Lemon Law and was awaiting final repair notice from the dealer. The failure mileage was 1,574.

WHEN PARKING OR ABOUT TO MOVE AND YOU PUT FOOT ON BRAKE AND GET INTO A GEAR A LOUD AUDIBLE POPPING NOISE COMES THROUGH THE STEREO SYSTEM. IT IS VERY LOUD AND NOT BASED ON HOW LOW OR HIGH THE VOLUME OF THE STEREO IS SET. THERE IS A THREAD ON TRAILBLAZERTALK.COM ABOUT IT NOW.

We purchased this 2021 Chevrolet Trailblazer RS new from the dealership and we noticed on the second day of owership that the brakes were "squealing". The dealership initially inspected the vehicle asap and without having to go through the service department. However, the problem not only continued, it persists to this day. Additionally, we just purchased a used 2023 Chevrolet Trailblazer RS (with under 10,000 miles) and are experiencing the identical issues with the brakes squealing.

BRAKES REQUIRED EXTREME PRESSURE TO STOP THE VEHICLE. ACCIDENT BARELY AVOIDED DURING RUSH HOUR TRAFFIC ON BUSY SURFACE ROAD.

WHEN IT IS DARK OUTSIDE AND YOU PUT THE VEHICLE IN REVERSE, THE LIGHTS NEXT TO THE BACK UP CAMERA CAUSES THE SCREEN INSIDE THE CAR TO SHOW BRIGHT WHITE. THERE IS NO WAY TO SHUT THE SCREEN OFF WHEN IN REVERSE. I HAVE TURNED THE BRIGHTNESS ALL THE WAY DOWN BUT IT IS STILL VERY BRIGHT MAKING IT IMPOSSIBLE TO SEE YOUR SURROUNDINGS SAFELY. I HAVE ALMOST HIT A TREE AND DROVE INTO A DITCH TRYING TO REVERSE AT DARK. THIS IS VERY DANGEROUS AND NEEDS TO BE FIXED.

BREAKS SQUEAKING

After putting vehicle into park and shutting off the engine, the warning appears “shift to park” and will not allow the vehicle to completely shut off. For the past few months I have been able to maneuver the shifter and the car recognize it is in park, however this past weekend nothing would work and the vehicle stayed in accessory mode until the battery died. I have spoken to two local dealerships and they are aware of the problem. I am currently awaiting a local repair shop to research the issue and get back to me if they can repair it and what the cost will be. This began in September, I am unsure the exact date. Upon researching this, there are hundreds of vehicles that have had or are having this issue going back as far as 2018 at least. General Motors has been aware since then and only issued an inquiry to dealerships last November. This is clearly a defect in manufacturing that should have been recalled and remedied long before now. I am without a vehicle and out of pocket for a repair that should not have occurred.

The rear hatch interior trim that seals the hatch from exterior elements and sounds continuously comes off, even after having dealership to repair/replace. The trim will not remain in place and is a distraction while driving and hearing out of vechile noise. And the winter weather causes car not to maintain a constant heat temp
