My wife and I were driving our 2015 Chevrolet Traverse on the interstate traveling at 80mph. When I took my foot off the accelerator the accelerator stayed in the down position and continued to accelerate the vehicle. We were up to 90 mph. I put my feet on the brakes and was able to slow the vehicle to 70mph. The accelerator was still stuck in the floored position and fighting the brakes. I was able to manipulate my foot behind the accelerator and after several attempts to pull the accelerator up it released. There was a loud clunk and we were able to pull the car off the interstate. When the car was placed in park, all the warning lights went on and the engine shut off. The vehicle would no longer start. Chevrolet towed the vehicle to the dealership where it was discovered the accelerator sensor and module went 'bad' per the dealer. The sensor malfunction caused the accelerator to stick per the dealership.
