After filling the gas tank of my 2005 Jeep Grand Cherokee 5.7 liter hemi I accelerated onto the interstate and the car began to decelerate and all the information lights came on and began to flicker on and off as well as the headlights. Vehicle then proceeded to drive normally with check engine light on but not pulsating. Dealer next day could not look at it as I did not have an appointment. After several stops and turning engine off the check engine light went out. Several days late the information gauge lights flashed and received a code message to service electric brake system. Then they recycled and has been clear since.

Local carwash employee entered into a 2005 Jeep Grand Cherokee. When ignition was turned on, the vehicle redlined and accelerated off of conveyor. Employee hit the break with no response. The vehicle collided with another vehicle and went through a towel cabinet and a brick wall. Four employees and myself were nearly killed. I took the driver out of the vehicle and while no one was in it, it was still trying to drive through the wall on it's own. (nothing was touching the accelerator).

I have a 2005 Jeep Grand Cherokee Laredo on 2 different occasions my engine sounds like it is revving at full throttle but I have no power. The RPM does not reflect this. Both incidents have been first thing in the morning and there is no warning. Fortunately I have had enough power to get the vehicle off the road. I estimate my speed to be approximately 5-10 mph. I am hoping that if you have had similar complaints that you can advise me what was done to fix the problem. I have had the Jeep to the shop on two different occasions but they advise me since they cannot replicate the problem they cannot fix it. Thank you for any assistance you can give me.

: the contact stated while changing the gear from drive to reverse there was a clicking noise. This occurred intermittently. While attempting to apply pressure to the accelerator pedal the engine made a roaring noise and the vehicle failed to pick up speed. The dealership rebuilt the transmission, however no other repairs have been made. The manufacturer has been alerted. Updated 6/27/2006 - the vehicle battery would not hold a charge. The headliner had to be replaced because it was unraveling.. the sunroof motor had to be replaced. The transmission was rebuilt on 2-27-06 with on 90000 miles. The memory seat did not move back at times when the key was removed from the ignition. The tire pressure monitoring system was inoperative. The power steering pump was binding and had to be replaced. The air bag light illuminated on the dash. The rear windshield wipers were not flush with the windshield.

The contact stated on three separate occasions the vehicle accelerated when the brake pedal was pressed. To stop the vehicle he put it in neutral, waited for the rpms to come back down. He took the vehicle to the dealership each time, and they were unable to diagnose the cause of the problem. Therefore, the contact sold the vehicle back to the dealership. The consumer stated he was injured. Updated 01/11/06.

Grand Cherokee 4WD 8-cyl

  • Automatic transmission
  • 11,567 miles
Repeated accident's of my vehicle going from idle (1000 RPM) to 1500-2000 RPM while vehicle stopped and in gear. Requires significant effort to prevent vehicle from surging ahead. Has occurred when vehicle is entering street from driveway, at a pedestrian crosswalk and at a traffic light. Local dealer placed monitor in car and it recorded four instances in a month. Damiler-Chrysler engineering claims no vehicle problem, driver is supposedly stepping on both accelerator and brake. This is not correct, both driver in our family have experienced problem. Car is unsafe.

I have a 2005 Grand Cherokee Laredo under 3000 miles. My engine light has come on less than 10 times, and my car has stalled when come to stop light or complete stop about 5 times. I have made 5 trips to the dealer and the first few times they could not find anything wrong with it. Then they determined it was related to the remote start which they had installed. I got it back and they said it was fixed and it stalled out when I pulled into my driveway that very day. Engine light came on again exactly 1 week later. Engine light is still on now. This will be my 7th trip to the dealer for this problem. I would also like to say that I have also hit the key in the ignition twice which made the car shut off and my car has also revved up with the brake on just as the other complaints on this site. I am also only getting 12 miles per gallon!
