The contact owns a 2011 Jeep Liberty. The contact stated that the accelerator pedal would become stuck and unresponsive, causing the vehicle to accelerate independently. The vehicle was taken to the dealer at least five times where they replaced the throttle body sensor but the problem persisted. The manufacturer was notified of the failure who informed the contact to take the vehicle back to the dealer for further repairs. A claim was also filed with the manufacturer. The failure mileage was 4,622. Updated 11/14/11 the consumer stated when the failure occurred, the engine would surge to 2600 RPM's and continue until the vehicle was shut off. The accelerator pedal was inoperable. The consumer had to slam on the brakes and put the gear in neutral. Updated 11/18/11 the consumer stated the vehicle would not accelerate over 40 mph, as the accelerator pedal was completely unresponsive. On a separate occasion, while stopped at a red light, the vehicle suddenly lurched forward through the red light into the intersection. The consumer stopped the vehicle from going any further by slamming on the brakes and throwing the transmission into neutral. The throttle position sensor was replaced, as well as the main computer. However, the consumer continued to experience problems. Updated 12/28/11
