While turning left at a major intersection, car lurched forward and gained speed/momentum while at same time steering wheel became stiff and very difficult to turn & driver could not control the car. Car did not complete the left turn but rather continued driving as if all on its own and crashed into a high curb on right side of car. Air bags did not deploy; front car parts simply crumbled and fell off; suspension was ruined; car tire was punctured along with the tire rim being cracked clear through in a couple of areas. Driver was injured with head injury, cracked rib, and broken rt. Forearm. Car was totaled out by the insurance company.

I noticed this problem not long after getting car when stopped in drive going from brake to gas car seems to act like its on oil slick then catches on with a sudden jerk. It will also when going from gas to brake even on incline will lunge forward it also will just suddenly speed up with out any acceleration its like the car is in cruise control. I have had car in several times and always they cant tell me anything I'm not the only person who notices this anyone who is in car asks what was that or what just happened.

Sudden and unexpected acceleration during a low speed (<5 mph) tight left hand turn. First incident resulted in crash against house wall, damage to vehicle. Vehicle repaired below insurance deductible, no damage to structure. Second incident in a parking lot, on or about May 16, 2012, able to stop vehicle with no crash. Third incident occurred at neighbors house June 26, 2012, causing crash. Damage to vehicle and garage door. All incidents occurred when lifting from accelerator prior to stepping on the brake to shift into reverse (vehicle still in drive, no braking). After 3rd incident vehicle was drivable but was towed to the selling/servicing Buick dealer. Vehicle is still being investigated by dealer. Condition does not occur every time in the same tight left hand turn. Type of turn is 90 degrees in driveways to side loading garages and into parking spaces.
