Five problems related to accelerator stuck have been reported for the 1997 Jeep Grand Cherokee. The most recently reported issues are listed below.
While travelling about 65-70mph vehicle suddenly surged forward, accelerated to around 78 mph. Engine revved, accelerator pedal stuck to floor, consumer could not slow vehicle down, finally shut off ignition. Chrysler said that a vehicle with that many miles that could happen.
The accelerator sticks when driving. The problem occurs when the vehicle is on a downhill grade while using a lower gear to limit downhill speed. While driving downhill the throttle sticks when a small amount of power is added to maintain a given speed. When driving under this condition if I add braking, the throttle (rpm) continues to stay at approximently 3000 rpm. At this point if I put the transmission into neutral the throttle stays at high rpm as I continue to coast downhill and doesn't reduce rpm until the vehicle has slowed to a stop. It's interesting how when in neutral that the vehicle recognizes the speed, or lack of, then reduces rpm once the vehicle has slowed to a stop. When driving the vehicle while in gear the same problem occurs. While in gear, if I brake, the throttle (rpm) continues to stick until the vehicle slows to a stop and then the rpm lowers to idle speed. (kinda hard on the breaks too!) I demonstrated this exact problem to a Chrysler rep. (bob hardy). Later I found out he had stated that the throttle sticking was "normal". After I had demonstrated the throttle sticking, I was told there was nothing that should be done because they had determined that the throttle sticking was "driver induced". What a ridicules statement! a catch 22! here, I finally get the opportunity to demonstrate the throttle sticking and it is used as their defense saying that I induced my vehicle to have a stuck throttle! I guess that's the price "I" pay when I demonstrate a serious defect and the manufacture wants to ignore it! I have complained about this defect for over two years, while it was still under warranty and nothing related to this defect was corrected. I must add, it took some time to realize that the throttle was sticking due to the circumstances involved, which made it difficult to recognize immediately.

The accelerator sticks when driving. The problem occurs when the vehicle is on a downhill grade in a lower gear while using the lower gear to limit downhill speed. While driving downhill the throttle sticks when a small amount of power is added to maintain a given speed. While driving under these conditions I can add brakes and the throttle (rpm) continues to stay at approximently 3000 rpm. At this point if I put the transmission into neutral but throttle stays at high rpm as I continue to coast downhill and doesn't reduce rpm until the car has slowed to a stop. It's interesting, how when in neutral that the vehicle recognizes the speed, then reduces the rpm to idle speed once it has slowed to a stop. If I keep the car in gear while breaking to a stop, it also eventually drops rpm to idle speed. I demonstrated this exact problem to a Chrysler rep. (bob hardy). Later I found out he felt this was "normal" and after I demonstrated the problem and was I told there was nothing that could be done and that they said it was "driver induced". I guess that's the price you pay when you demonstrate a very serious problem and the manufacture wants to ignor it! I have complained about this problem for over 2 1/2 years while still under warranty and nothing related to this problem was corrected. I must add that it took some time for me to realize that this was happening because you can break while the throttle is sticking and then when stopped it drops rpm. This can tend to mask recognizing the problem immediately.
The accelerator is sticking while the vehicle is on a downhill grade and a lower gear is being used to limit the speed, the throttle sticks when a small amount of power is added to maintian speed, when the consumer brakes, the rpm continues to stick, the dealer informed the consumer that the throttle sticking is normal.
