Example complaints

“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.”
NHTSA complaint #11415441, filed 2021-05, 160 miles“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.”
NHTSA complaint #11394975, filed 2021-02, 7,300 miles“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.”
NHTSA complaint #11633315, filed 2024-12“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. …”
NHTSA complaint #11433212, filed 2021-09“When stopped at a red light & the light turns green & I accelerate, the vehicle does not move. It makes a loud noise and jumps. This happens way too many times. There’s also an issue with the brakes, when you press on them, you can hear something grinding, which should not be happening because I bought the car brand new. Also the brakes have always been super squeaky, which is very frustrating because they should not be with a brand new car once again. The engine light goes on and off randomly and doesn’t say anything.”
