Sonic 4-cyl

  • 55,200 miles
My mother stated that she was sitting still at a red light waiting for it to turn green when out of no where the engine revved up and the car lunged forward causing her to strike the car that was in front of her. She managed to steering around that car and bring the car to a stop. She and my sister told me this is not the first time this has happened. Both times the car was standing still and her feet were on the brakes.updated 06/03/14
