“My car shut off two times while driving. When you google the issue, it auto populates meaning that this is a very common issue with GM. It starts back to 2015 searches as well. GM needs to recall their suburbans for their cars turning off while driving which caused me to lose power steering, power brakes and anything that requires electrical.”
NHTSA complaint #11522047, filed 2023-05“Total Brake failure without warning, DTC, or messages. Coming out of a parking lot applied the brakes and the brake pedal went to the floor and was not able to stop. I tried pumping the brakes which pedal to return to the correct position but went back down to the floor. Had the vehicle towed to the dealer which confirmed the truck needed a new master cylinder, brake booster, and vacuum pump.”
NHTSA complaint #11459164, filed 2022-03“Have had starter problems since we purchased the vehicle. Starter intermittently loudly grinds when pressed 2-3 times a week and won’t start. Dealership could repeat problem once, but never fixed it. Took vehicle in at least half a dozen times. Never fixed. Car also makes an odd humming when gas is applied. This week, car started and died after driving a foot. Then car wouldn’t start at all. Brakes stiffened up and wouldn’t compress without substantial effort. Everything resolved on its own within 30 minutes. …”
