While driving up an incline at 25/30 MPH accelerator pedal went all the way to the floor and vehicle accelerated at a high speed. This was caused by the throttle body part sticking in open, per dealership.

An intermittent problem with engine surging and causing sudden acceleration. Vehicle been to the dealer on three occasions, and they were unable to duplicate the problem. Feel free to provide any further information.
There is a random feeling during acceleration and stand-still of which feels like a down-shifting beneath the SUV. I have had it looked at by several different dealers and they all just give me the 'run-around'. I think there is something workng and no one wants to fix it because it might prove costly.
Rotors have warped after about 7000 to 8000 miles resulting in lurching when trying to stop vehicle. Front rotors have been replaced twice and all rotors resurfaced 4 times by dealer, 3 times under warranty and 3 times at my expense. As rotors get bad, stopping distances increase and vehicle is difficult to control when stopping from highway speeds. Vehicle has only been driven in florida, and has not been driven in salt water or off-road. First problem reported to dealer when vehicle was 8 months old and had 9294 miles on odometer. The problem recurred again, each time, approximately 7000 to 9000 miles following the last brake service.
I pulled out of a gas station onto a major busy street and accelerated the car and passed a major busy intersection. As I accelerated the vehicle, I heard a loud boom coming from the front of the car and was startled by the loud boom. As I passed the intersection I noticed that all of a sudden I have no control of the steering wheel whatsoever(it locked up). I tried to pull over to the right passing some parked vehicles on the street & there were a lot of vehicles behind me. I managed to move the car to the right, with my foot on the brake, without hitting a parked car in front of me. My front right tire of the car crashed into the curb and stopped. The car was parked at an angle not parallel to the curb and I was afraid that some other car might hit me from behind because of the way my car was stopped. I was shaken up a lot and when finally got out of the car I saw fluids leaking out from the front of my car onto the street. A couple of people came out of a business storefront and saw the fluids leaking out fast onto the street.one guy said that was oil leaking and could not see anything else. It was already dark (around 5 p.m. Pst).I called my husband and both my husband & my brother came to the location to see what was wrong and both couldn't figure out why oil was leaking. The car could not start and a tow truck was called and towed the car to a jeep dealer (where we normally have the car serviced) in alhambra.the following day the jeep dealer's mechanics examined the vehicle and they said the whole engine was taken out and that apparently there's a hole at the bottom of the engine block. Three days later my cousin (also a mechanic) was able to look at the engine and said that the connecting rod inside the engine broke and thus made a hole on the side of the engine. We also have the car service at a jeep dealer with oil change every 3,000 miles and do all the mfg recommendation. In feb. '01 we had the car serviced for the 20,000 maintainence service.
While at a stop applied brakes, consumer heard a grinding noise. Then, vehicle suddenly surged forward. Consumer kept foot on brake, but could not stop vehicle. He had to shut off engine. Vehicle at dealer at this time. *ak dealer states that there are no problems with the vehicle.
Brakes vibrate at high speed and cause lurching at low speed. Rotors refaced twice and replaced once. Now problem has returned. After reviewing the federal safety agency web site and finding numerous other complaints, it is obvious this is not an isolated incident but a recurring problem on this vehicle. It should be fixed!
Dead battery from overnight flickering of lights. Difficulty with lowering/raising right front passenger window, appears to have no power. Left headlamp appears to be burned out, when ride over bump it goes on. Lights/headlights on dashboard flicker on/off while car is in garage parked. When driving and lights flicker on/off, it appears to get a surge of power and car surges forward.have taken to dealer and they cannot find anything wrong with it.
Vehicle lurches forward in reverse. Dealer took 6 months to find a remedy. Dealer has no remedy for vehicle potintially going in reverse. Problem can't be duplicated.
While driving 35 MPH vehicle suddenly accelerated, consumer applied brakes, but this did not stop vehicle. Consumer kept pushing brake pedal to floor, and after a few seconds, vehicle slowed down. Mileage was 3000. This happened again on 4 aug 2001 while driving about 5 MPH in a parking garage, vehicle accelerated while in reverse. Applied brakes, but there was no braking action. Vehicle came to a stop when it hit another vehicle. Damage to jeep was $5700.00, damage to other vehicle unknown at this time. Both times, no injuries.*ak
While driving vehicle will rev up and accelerate suddenly. Dealer has inspected vehicle. Please provide additional information.
Vehicle lurches forward one gear to next. Vehicle does not engage in gear properly. When in reverse vehicle would delay, and then it will jump back. While driving on the highway all power will go out without warning. *ak
Exiting interstate, approaching stop sign, engine rpms did not decrease after release of foot-feed. . Had to "stand" on brake to keep from going through intersection. Shifted into neutral, then into park. Rpms then returned to normal idle speed for a stopped vehicle.
Due to transmission ,vehcle will lurch forward when idling at a stop or at random, and driving at approximately 20mph with foot off accelerator. Vehicle will clunk very hard lifting consumer off seat. Vehicle was taken to dealer 6 times, but dealer could not find cause, and consumer felt dealer was in denial.*ak consumer states the transmission seems to be a problem, it experiences rough shifting, bumping, and clunking.
First, brake related problems: mileage 2341 complaint pulsatting when stopping 20-55 MPH , front brake rotors were resurfaced , complaint 2 mileage 16040 brakes pulsatting when stopping also shimmy in steering 45-55 MPH, front brake rotors were replaced reason warpage due to overheating design flaw? / complaint 3 mileage 17000, brakes pulsatting , vibaration in vehicle and steering wheel shimmy when brake are applied. Have not rportedto dealer at this time will schedule for week of 07/16/01. Secondly, transmission shift problems: started when vehicle was brand new when stopping it felt like someone was hitting you in the rear end. First repair ,mileage 4428 consisted of tsb0300799 and replacement of rear driveshaft,also rear axle carrier and pinion bearings were replaced.second transmission repair mileage 10453 due to harsh shiffting @ 20 MPH and again when stopping it felt like someone ran into the rear of the vehicle, this time the transmission yoke was replaced and another transmission update per tsb21-09-00,also during this service the front driveshaft was replaced due to a howling noise which started around 55-60 MPH, complaint three mileage 10818 vehicle still has whining noise coming from drive train. In addittion, transmission problems continue with harsh shifting at times at 20 MPH and 50-55mph,these shift points worsen as other problems were being corrected,dealer claims that thhis is adaptive memory and their nothing that will be done to correct it. According to casey jeep service manager daimlerchrysler does not see this as a problem only an issue. Fourth complaint mileage 16040 transmission continues to shift hard at times @ 20 MPH and 50-55 MPH. At this time dealer show no concern in correcting this problem . In summary, brake and drive train problems with this vehicle starting at 2341 miles, and they continue be on-going. I now question the safety of this vehicle.
Vehicle has been to dealer 5 times now for very rough idle, engine sag, idle undershoot, etc. Pcm has been reprogrammed with current software, etc. Dealer called chrysler and was told no fix is available for this condition. Vehicle shakes and tries to die. Very unsafe to drive as may die when trying to pull out. Dealer basically says chrysler knows of the problem but won't fix it properly.
On both failures the jeep was in park, with the brake on and the engine idling. The car literally took off in reverse and both times was only stopped by fences. Both times the vehicle was on flat ground. I reported the first incidence to the dealer and they said that if I couldn't prove it, they weren't responsible and therefore I would have to pay for the damage. I did not report the second incidence, but I have also not fixed the damage. I am terrified to drive the vehicle. Scc ***dimsii ivoq entry posted after 12/12/02 cut-over to artemis****747979
When using cruise control and driving uphill, vehicle will downshift to first gear, causing driver to be thrown forward. Dealer stated this was a known problem, and chrysler did not have a remedy. *ak
Sudden acceleration upon backing into a poll, engine commenced to accelerate out of control with both foots on brake and shifted into park. Vehicle was force into a concrete wall at 35 MPH. Also, both air bags did not deploy. Manufacturer notified and informed of a representative would be sent out to inspect vehicle. Please feel free to provide any further details on this matter.
Sudden acceleration when applying brakes, intermittently. Dealer notified, and made some repairs, but problem still reoccurring. Please feel free to provide any further details on this matter
When slowing down at a red light with foot applied to brake pedal vehicle suddenly accelerated, cause unknown. Dealer cannot identify the probelm.
Due to a defective rear differential in the transmission which been replaced once, while driving vehicle lunged forward, which may have caused a crash. Also, in reverse position there is a loud noise. Problem still exists.
The car was in neutral:the air conditioner was on: my foot was on the brake. With my foot on the brake, the car was placed into drive. The wheels spun and left rubber tracks as long as 24" on the pavment although my foot was not on the accelerator. With the car careening forward, I depressed the brake pedal with as much force as possible, but the car did not respond and continued forward.the vehicle stopped only when it went through the wall of my garage.the air bag did not deploy. My foot was never on the accelerator. As soon as the car stopped, I checked the location of my feet and I confirmed that the accelerator was not being depressed. I had the police come and prepare an acident report which recorded the acceleration marks that remained on my driveway as a result of the sudden and high acceleration which was incurred.
Intermittent engine idle problem. Occurs when engine is fully warmed up and in gear and at a full stop. Engine idle speed will fluctuate between 300 & 600 RPM . When this happens, engine roughness is very noticable and on occassion it will stall. On the first visit to the dealer, the computer was reprogrammed as per a tsb. This did not solve the problem. Second visit, chrysler advised the dealer to replace throttle position sensor. Again the problem still exists. The dealer has notified chrysler and is still waiting for an answer.
Dealer examined and replaced the control unit twice. No help. Idle speed is too low (400mph)! I want jeep to do something. It's a lemon!
