See attached document for complaint
Pushed accelerator to floor. When I took my foot off the accelerator car continued to accelerate at full throttle for about 15 -20 seconds. Uncontrolled acceleration stopped when I pumped the accelerator. Chevrolet dealer found no fault codes due to a problem with the fly by wire. It appears that when the accelerator was pushed all the way down it somehow got caught and held in the full throttle position by the GM rubber floormat even though the floormat was held in place and attached to the carpet by the fasteners that GM supplies. I had the car and mats for about 2 years before this very dangerous event took place. The local GM dealer cut and removed part of the mat by the accelerator to prevent possible mat contact with the accelerator. However, the dealer could not confirm the floor mat was responsible for the incident.
This is third occurrence. When doing hard acceleration (to merge onto road or pass vehicle) the vehicle would not stop acceleration. Hard braking did not disengage acceleration. Placed car in neutral and applied brakes. When placed back in drive continued hard acceleration. Placed vehicle in neutral and came to stop. Placed in Park and then drive continued hard acceleration. Had to bring to stop and power vehicle off.. Dealer will triage to see if error codes available. They want me to continue driving since no loaners available
