The message "Brake Failure - Speed Reduced to 53 MPH – Service Required" was displayed on the instrument panel. The vehicle was taken to a dealer; however, the dealer stated that the vehicle could not be diagnosed because diagnostic tests were available only by appointment. The dealer informed the contact that the computer software needed to be reset to drive the vehicle back to the residence. The vehicle was not diagnosed or repaired. The manufacturer was notified of the failure and provided the contact information about a recall; however, the VIN was not under recall. The failure mileage was approximately 135,884.
Getting error message for shift to park not found when vehicle is in park. Chevy already has a recall for this but my vin is not one showing it is affected. Vehicle is at the dealer now for diagnosis and repair.
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.
I have brought my car into the dealership over the last few years at least 6 times for the same issues. Currently there are two codes coming up as permanent on my car which is for the Evaporative Emission System Flow and Brake Booster Hydraulics performance. I drive my child of three every day and the number of times my check engine light comes on and goes into reduced engine power is not okay nor safe.
The brake pedal goes to the floor and does not want to stop. There is a brake failure meesage on the dash.
Brakes failed and myself and others were in harms way. To my knowledge the car was totaled as the air bags did deploy.
The brakes make squealing sound when coming to a stop. the dealer has acknowledged the problem and said there is nothing they can do about it and that the problem is normal. It is not normal for brakes to squeak every time the car stops.
The brakes squeak and squeal at low vehicle speeds including when in reverse.
The brakes squeal and squeak when in reverse and applying the brake when going forward at low speed. I have been told there is a GM service bulletin that says this is normal for the brakes to make this very loud noise. I have not seen this bulletin and have not been able to find the bulletin online. At any rate this is not normal for a car with 7600 miles to have brakes that squeal all the time. I have taken this to two different dealers and get the same answer but I do not believe it is proper to make a customer deal with this when they spend close to 30k on a car and you will not fix it because it does not cause a safety issue. Bumper-to-bumper warranty coverage should mean just that.
The ABS and stability control systems crash without warning. Randomly on a trip the check engine light randomly comes on without warning and immediately my break system stops being effective. I have to put full force on the brake pedal to start breaking the vehicle and coming to a stop becomes difficult. This puts my life as well as others at risk as I would not be able to break on time. The problem immediately goes away after turning the car off and turning it back on leading me to believe it’s simply a computer problem. The service provider Chevrolet has not reproduced or confirmed the issue to my knowledge. No warning lights come on prior to the issue nor does the check engine line persist after being turned off and on again.
Brakes squeal when in drive. Any amount of pressure on the brakes the car shakes and a loud squeal begins. Bought the car new in May and this issue started in June. Have taken the car to the dealership since June to try and figure out the issue. Dealership states that rotors and brake pads are in perfect condition, thus the issue being the actual brake component. Dealership will not fix despite car being under warranty because there is no bulletin out for car model. I am very concerned for my safety and the safety of others when driving, especially since the dealership knows their is an issue and will not fix it.
STABILITRAK STABILITY CONTROL SERVICE AND SERVICE ANTILOCK BRAKING SYSYTEM 2 TIMES SINCE I HAVE OWNED IT FOR ABOUT 2 MONTHS
THE BRAKES INCLUDING BRAKE ASSIST STOPPED WORKING. PRESSING THE BRAKE PEDAL DID LITTLE TO STOP THE VEHICLE. THERE WAS RECALL FOR THIS SAME ISSUE THAT WAS PREFORMED BY THE DEALERSHIP 3 WEEKS AGO.
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.
