While parallel parking, with my right foot on the brake pedal, I shifted the automatic transmission out of reverse. Immediately the engine rapidly revved up and lurched forward. I pressed more firmly on the brake, causing the car (a 2004 Jeep Grand Cherokee) and motor to pause, then the motor rapidly revved up again, overcoming braking. Horrified, and unable to stop the car, I watched as the car raced into the vehicle ahead of me. Immediately after the impact, the engine returned to normal idle. I then checked the car: cruise control was off, my hands were still gripping the steering wheel in order to provide additional leverage for my foot on the brake pedal, my right foot was still firmly in the middle of the brake pedal and not near the accelerator pedal, and the gear shift lever was in neutral. The vehicle ahead of me sustained damage to its bumper and tailgate. This is the 4th time this has happened with this vehicle, the first two of which were reported to you earlier. In all three earlier cases, I was able to barely avoid an accident, but not this time. As noted earlier, the Jeep mechanic was not able to find any causative problem.

My 2004 Jeep Grand Cherokee limited has either a hole in one of the pistons or a broken connecting rod. This just happened one day as I left work. The vehicle would not accelerate properly and ran very rough.
The contact owns a 2004 Jeep Grand Cherokee. While making a left turn at 45 mph, the vehicle accelerated without warning. The vehicle would not stop when the brakes were depressed. The contact was finally able to decelerate and turned the vehicle off. The failure was due to the throttle cable becoming stuck. The vehicle operated normally once the throttle cable was released. The vehicle was driven to a repair shop where it is currently being diagnosed. The purchase date was unknown. The current and failure mileages were 33,010.
Since purchased in 3/06, 2004 gc v8 while idling, repeatedly dies, or nearly dies but recovers only to cause a lurching forward if in gear. Will die in gear or in park and I am able to start it again right away. Dealer, after three tries cannot find anything wrong. May go two weeks without happening, may happen twice in one day.
1 month after buying my Jeep it died out at a stoplight. Dealer could not find anything wrong with car. A month after getting it back, it died 2 more times at stoplights. I took it back to the dealer who said the computer needs to be replaced. Now waiting for the new computer which will take a week to get here. Hopefully this will correct the problem, but I've seen many of the same complaints from other people on this site.
Engine would stop running at idle. The dealer placed a CO-pilot on the computer, however it shorted out, consequently the dealer had no idea as how to fix the problem. The gas mileage on the vehicle was poor.
