1999 Jeep Grand Cherokee acceleration complaints
Page 3 of 3: complaints 41 to 57 of 57, newest first, as owners wrote them.
While switching the vehicle from neutral to drive owner put foot on gas pedal and the vehicle took off. Owner applied brakes and vehicle kept going until stopping on its own will. Engine still revved while being stopped with the brakes. Dealer said there was no problem.
Vehicle has suffered from warped rotors which were replaced twice on the front and once on the rear. No problems since 12998 miles. But I consider this to be due to poor quality. Main issue reoccurring ,stalling problems while stopped in drive. Vehicle has been in three times for checks to throttle body (cleaned and once replaced), software revisions and other settings, but stalling continued to manifest itself. Has stalled 3 times in the last 3 weeks. Contacted daimler chrysler who kept referring me to the dealer. But after multiple visits I have no confidence in their ability to address this problem.
Brakes: front end shakes when braking, rotors turned by dealer, but problem continues - dangerous. Differential/transfercase: loud clunking noise from rear, 'roaring' noise at speeds of 30-40mph and 65-75mph. Engine: stalls(dies out) when idling in gear and when putting gear from park to reverse, delear doesn't know how to fix. Vehicle lunges forward when coming to a stop, almost hit vehicle in front - dangerous. Idles roughly, rpms go up and down at stops, stalls. Steering: pulls to right, dealer says alignment is fine. Noise from steering column when turning. Ac: lots of water condensed inside of vehicle at passengers feet when AC on, dealer says normal.
The vehicle has many defects which have been noted by many owners ; the car stalls or the rpms fluctuate wildly when stopped and idling. There is also a lunge or jolt once the vehicle comes to stop.
While applying brakes vehicle suddenly accelerated out of control, resulting in a collision. Dealer has inspected and repaired vehicle.
While attempting to fill gas tank, gas frequently spills out when tank is full without kicking off auto-shutoff feature of nozzle. On one occassion, with the tank nearly empty and the nozzle properly inserted into tank, gasoline immediately flowed out of tank and onto ground when pumping began. Again without shutting off auto-shutoff feature of nozzle. On numerous other occasions, when inserting nozzle into tank, before beginning to pump, gasoline from the tank would spew out when nozzle was inserted. In all occasions, I was sprayed with gasoline.
Repeated problems with AC/heat being erratic, will take vehicle in for 4th time. Vehicle shuddered, fixed by changing fluid. Weather seal fell off. Brake shudder fixed by replacement of rotors, etc. Engine stalled fixed, but the rev up and lurch at stop is not yet. Setting another appointment with service.
Vehicle lunges forward slightly when stopped at a stop-light or when vehicle is in gear but not in motion when brake pedal is depressed.
After stopping and releasing the brake pedal, vehicle lurches forward as if it has been rear-ended
When taking off from a complete stop, accelerator locked up, causing the vehicle to accelerate to a high rate of speed. After colliding with a couple of vehicles and a fire hydrant, vehicle slowed down. After applying the parking brake, vehicle came to a stop. The manufacturer has been notifed about the problem. Report given by liza delcampo at state farm insurance. Tsb# 18-40-98
While slowing down to stop at a red light, the vehicle downshifted (auto) properly. At approx. 15 - 20 MPH while the brake was depressed the engine revved up as if to take off. I shifted to neutral and the tachometer almost red lined. (similar to the audi 5000 problem early 80's.) the second time this happened was after making a u-turn on a dead-end street and proceeding to stop at a stop sign. Both feet were on the brake pedal. The vehicle has been towed back to the dealer on 07/06 with 116 miles on the odometer. Outcome still pending.
4 attempts have been made to fix this problem. When engine check light comes on, gas mileage drops severely and engine rides rough. Vehicle has been out of service 29 days and problem still persists.
When speed control is engaged, at any speed, throtle surges ahead 2-7 MPH. Very dangerous in traffic! Chrysler shop manual confirms this problem on all jeeps. Chrysler refuses to fix problem.
Vehicle experiences backfires, jumps forward when stopping and RPM's fluctuate continually, replacement of transmission did not rectify problems.
Idle goes up and down at stop. Idle goes up and jeep will gain speed without foot on gas. Idle goes up and jeep will gain speed in reverse. Idle "burps" at stop and jeep jumps like it was hit from behind. Rear end whines while traveling and get louder till 75mph then mostly subsides. Transmission was replaced ( for no reason we could tell) to stop whine. Whine continues in the rear end. Dealer states "normal". Steering wheel shakes on extreme left or right turns forward or reverse until transmission was replaced. Dealer stated shaking was normal. Jeep has 2000 miles.
As my husband shifted from park to reverse, our new jeep lurched or accelerated so quickly that the tires squealed and smoked. We aren't sure if it "jumped" out of park or if as it went into reverse it was accelerated or floored. I was thrown from the vehicle, severe concussion, dislocated jaw, etc... Manufacturer and dealer have inspected and find the vehicle "mechanically sound". We are afraid to drive it ever again.
