- the contact owns a 2004 Jeep Cherokee. The contacts vehicle accelerated without warning. The contact was unable to engage the brakes, which almost caused a collision on the highway. No matter how hard he applied the brakes the vehicle would not stop immediately. This failure occurred on two occasions. The contact drove the vehicle to the dealer, who stated that the gas pedal and brake pedal were too close together and he was engaging both at one time. The contact stated that the failure was due to the vehicle speed control:accelerator pedal. The contact had spoken to several owners and they are experienced the same failure. The failure occurs occasionally in the morning. Updated 08/13/07

When breaking to come to a stop at a stop light, slowly rolling at about 5 mph, the car suddenly accelerated on its own and lurched forward. I had to press down on the break pedal very hard to stop the car, the same time it was accelerating. This lasted about 2 seconds, and then the acceleration stopped. When I returned home I took the car into the dealer and the dealer said that it would probably not be able to diagnose the problem unless it did it again when I took it in. It has not happened again since. The auto is a 2004 Jeep Grand Cherokee with a V-8 engine.

Soon after startup, moving slowly forward or in reverse, as when entering a roadway or backing out of the garage, and after removing foot from accelerator while braking vehicle resists this action and the engine rpms speeds up to 1300 rpms +. very high braking force was required to overcome the problem. There have been at least 5 instances of this. The local dealer was unable to offer any plausible explanation or help, although he put a recording instrument on the car for a while. My passenger has witnessed this problem at least two occasions. It was an accident threatening situation in at least two instances. Vehicle cannot be trusted.

Vehicle experienced sudden acceleration. After coming to a complete stop and idling. The rpms suddenly revved up, then went back down, followed by sudden acceleration. When this occurred excessive force had to be applied to the brake pedal to stop the acceleration. This resulted in consumer's vehicle almost running a red light and hitting a pedestrian. Dealership had done several diagnostic tests, but was unable to determine the cause of the failure.
