Problem with engine revving while vehicle in or out of gear
1997 Jeep Grand Cherokee acceleration complaints
Page 2 of 2: complaints 11 to 36 of 36, newest first, as owners wrote them.
While driving 5 MPH and applying brakes vehicle suddenly accelerated to 35-40 MPH uphill. Consumer put gear in neutral to slow vehicle down. Dealer claimed accelerator pedal linkage was bend and caused acceleration.
Consumer accelerated after a stop and vehicle began to go backwards. Consumer applied brakes and accelerated again, vehicle repeated itself. Consumer put vehicle in park and back to drive, it was normal. Manufacturer is aware of problem, but nothng could be done until a recall is issued.*ak consumer also stated that vehicle has had 2 sets of brakes at 22,000 miles.
Would be driving vehicle and it would hesitate. Would rev up as if in neutral. Would suddenly kick in, and then accelerate. Have taken to dealership, and was informed by mechanic problem was low transmission fluid. After changing fluid in transmission was driving again, an d problem still occurred.
Rpm's to 4000, MPH 30; dealer claims problems with other customers with same problem. Diagnosed as "valve body and governor censor" replacement. Engine check light has been an ongoing problem since vehicle was purchase. Sometimes it goes off prior to the dealer, other times dealer claims its a minor problem. Warranty applied most times, now I am being nit picked everytime the engine light goes on, but this time it is serious.
We were on oour way home on the freeway, it was stop and go traffic, we were not going more than 3mphand my foot applied on the brake when the jeep lurched forward and struck a boat and the outdrive causing $5000 to my vehicle and the boat is still in repair.
Transmission locked in park, only way to get it out was to press hard on gas pedal, this caused vehicle to dash forward, consumer felt this was very unsafe because consumer didn'y know when it was going to dash forward. *ak
When applying gas pedal vehicle feels as if it is pulling in reverse. This happens at highway speeds. Dealer has not seen vehicle. *ak consumer states vehicle bucks and pulls back while driving.
At 07:45am husband parked vehicle, placed drive selector in "park', engaged emergency brakes, left engine idling. Wife, jo, entered vehicle. As she was engaging safety belt the car suddenly accelerated to a very high RPM and , simultaneously, jumped into reverse gear. The jeep struck a parked sedan and apparently the im[pact switched the gear into forward. Wife was unable to control and the jeep struck a house . Husband opened door and turned off engine w/ ignition key. Engine stopped.. Emergency brakes remained engaged throughout. Police report confirms "not the driver's fault".investigation by insurance adjuster/repair shop ongoing.
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.
Engine speed continues after gas pedal is released at speeds between 35 and 60mph. Speed continues unless driver shifts to neutral. Engine speed increases to 2500rpm while in neutral and remains at 2500rpm until car is braked to less than 20mph. This failure to decelerate occurs every time the vehicle is operated over 35mph. The brake repair and differential replacement occurred before taking delivery of the used vehicle. Maybe the brake and differential failure are related to the failure to delerate without the use of the braking system. Naperville jeep and koller dodge both recognized the issue and replaced the throttle motor and throttle body but the failure to decelerate continues. Chrysler's star hotline says this failure to decelerate is normal. I have test driven other 1997 5.2l jeeps with trailer packages and those vehicles decelerated normally, in a manner similar to all of my other 45 years of driving experiences. The jeep dealer claimed that mass produced vehicles normally have this variablility in behavior. They even suggested the deceleration problem was my fault because I bought the car.
The transmission was slow to connect and the RPM's were going up and no movement was occurring.
While vehicle was in park with the motor running, it jumped into reverse. Took off and hit a pole. Vehicle was taken to the dealership and repaired. *ak
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.
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.

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.
Have repeatedly (eight of more times) over the past +2 1/2 years, while under warranty complained of throttle sticking to dealer and manufacturer. As of march 24, 2000, after defect was indisputably deminstrated to chrysler factory rep. I was told "there is nothing abnormal occurring" and no repair were necessary. They also said after the defect was demonstrated to them it was caused by "inducement".
After exiting car wash with the gear still in neutral, there was a sudden acceleration which caused the car to crash into a concrete enbankment
Consumer was traveling in light snow and doing 5-10mph with foot on the brake and ABS engaged. Vehicle suddenly accelerated, causing him to rearend vehicle in front. No one was hurt, but the airbags didn't deploy.
Constant RPM fluctuation, hesitation under load, shifting from overdrive to drive during freeway speeds, chronic.
I was parallel parking the car on my residential street. I was in reverse and proceeded to back into the parking space. The cars both in front and behind me were some distance away. Suddenly the engine reved to a very high RPM and the car shot forward and crashed into the car in front of me. The car was still in reverse when I turned off the ignition. Several persons witnessed the incident. They heard the high rev of the engine, and also noted that the backup lites were on when I hit the car in front of me. I have owned 3 jeep cherokees and have driven them for the past ten years so I am very experienced in driving this vehicle. I am positive that this car was in reverse when the sudden acceleration occurred.
When owner got out of vehicle to unlock house door with the ignition running, not sure if vehicle was in the parked position, the vehicle remained in a still position for a few moments, then proceeded to roll forward, picked up speed and went throught the garage door. Continued to build up more speed going through the back of the back of garage until stopping. With the vehicle showing the drive position. Chrysler could not find a problem with vehicle.
Vehicle experienced sudden acceleration, causing a collision.
While driving with cruise set at 70mph, suddenly cruise control accelerated to over 90mph, brake action seemed ineffective to stop, brakes only slowed vehicle to 40mph, placed vehicle into neutral, then turned off ignition to stop.
