When the gas pedal is depressed fully, the gas pedal sticks the car continues accelerating. The problem began with initial complete depression of gas pedal to cause some acceleration and depressing brake allowed vehicle to return to normal driving. The problem has worsened over time to the point where both feet depressing on the brake pedal did not affect acceleration and caused smoke to emit from both front brake pads, and the passenger front brake pad flamed up from the heat. The car was driven into a parking lot with the brake depressed the entire time, and turned off. So far, this has only happened when the gas pedal is fully depressed. The dealer told me the mat caused this even though the mat is cut around the gas pedal with plenty of room to not obstruct pedal. The mat also does not slide or move about the area. The GMC dealer told me they took the mat out and did not notice any auto acceleration, and they told me they were unable to depress the gas pedal full to attempt to recreate the problem, to not compromise the safety of the other cars nearby.
On repeated occasions (from 2015 to 2019) I have experienced sudden acceleration at low speeds and sudden jerking motions. The transmission and speed controls are unpredictable and dangerous. This is hazardous and may result in a loss of control. I have also experienced numerous issues with the brakes including a stuck caliper at approximately 42,000 miles. I reported these issues and numerous other issues to GMC corporate, tustin Buick GMC only to be told that it was a software issue and things are satisfactory and safe. GMC contends that the vehicle is fine and declines to assist with issues. This is an ongoing issue. The date below is approximate. The mileage is approximate on all entries.
My GMC youkon denali has brake lights that are known to dealers to fail. Yet there is not a recall. I looked on the inter net and saw that there has been this problem since 2015 to 2018. Because of a joint that was soldered instead of a wire. I know why when I brought it in for recall that the service man looked at my stop lights.
