I was third in line waiting to pull out of a parking lot in peoria, az in my 2005 buick rainier. my foot was resting on the brake pedal. all of the sudden the car revved up and surged forward (from a standing start) with enough force to crash into the car in front of me and pushing that car in to the one in front of it--all three cars were severely damaged. *tr

Design fault - air pump is mounted low on the frame of 2005 buick rainier. on 10/30/07 it failed and had to be replaced. mileage at that time was 30,947. pump failed again because of water intrusion. since it is mounted low without any shield i would expect rain water to splash up as you drive. pump was replaced a second time on 12/12/08, mileage was 39,994. the second pump only lasted 9,000 miles and gm refuses to pay for replacement ( the warranty is for 12,000 miles or 12 months, your part is 13 months old). *tr
