2008 Jeep Grand Cherokee Owner Comments

problem #1

Jan 282012

Grand Cherokee 4WD 8-cyl

  • 50,200 miles


I started the Jeep and traveled normally for about a third of a mile on local streets. The problem started when I turned onto a collector street from a local street applying full throttle. When I lifted my foot off the throttle pedal the Jeep kept accelerating. The electronic throttle control warning light went on. I stopped the car by applying the brake and putting the transmission in neutral. The engine continued to rev at about 4000 RPM with the Jeep stopped. I turned off the Jeep and checked the position of the carpet protector to make sure it was not interfering with the accelerator. It was not in a position where it could overlap the throttle. I also checked the accelerator pedal and found it operating normally in terms of position and action. I turned the engine back on and the Jeep reacted normally for the remainder of the trip. Dealer not able to replicated but reported error message that both brakes and accelerator were both depressed. Also reported that carpet was not involved.
