“An incident with the vehicle occurred sometime around christmas 2011. The motor surged while I was fully stopped at a street light. The motor was running, the car was in drive gear, and my foot was on the brake. I was able to quickly bring the car under control. A second event occurred in 2012, may 15th, at 11:00 p.m. While I was fully stopped at a drive through window. Again the motor surged, this time with a loud screeching sound. I applied maximum brake pressure but the car continued to surge forward, approximately six feet. …”
