NHTSA complaint #11098186, filed 2018-05, 1 miles“I've attached my final repair notice to GM and it has all of the details. I have since taken my car back to the dealership to have the final repair done. They still say nothing is wrong with it. I am terrified to drive my car. I asked GM to take the car back and they say they are not willing to do anything at all to help me. The transmission is jerky and the brakes barely work. Please investigate. Its like GM would like to wait until there is a huge accident and loss of life before doing anything.”
