| Description of the problem | Sudden acceleration! Happened approximately 6 months ago and again on may 10th. Going slowly towards a stop sign while braking to stop, the car suddenly accelerates and lunges forward. Stepped on the brake but car keeps going. Put shift lever in neutral with engine racing and after about 2 seconds the engine slowly drops to idle. No accidents caused because no one was in front of me. Very dangerous situation! Took car to the dealer on may 15th and they could find no codes present and said the vehicle was operating as designed. |
