I double checked to make sure the cruise control function was off and the vehicle continued to accelerate on its own at a high speed, up to 55mph.when I drive, I am constantly hitting the brakes to keep from colliding with other vehicles. When I put the car in park, the rpms reach 30,000 and the engine sounds like it's accelerating. This is a safety issue. …”
