Tl* the contact owns a 2005 jeep grand cherokee. While the cruise control was engaged at approximately 70 MPH, the vehicle erroneously accelerated to speeds above 90 MPH. The vehicle slowed down after applying the brakes. When the brake pedal was released, the vehicle experienced unintended acceleration again. The driver forced the transmission into the park position to stop the vehicle. The vehicle was towed to an independent mechanic. The cause of the failure was not determined. The local dealer and manufacturer were not notified of the failure. The failure mileage was 245,247.

Air bag light is constantly flashing and rendering cruise control useless. Everything work as necessary, then one day when attempting to get on highway, I pressed cruise control only for it to flash in the dash panel, then disappear. Once off the highway to my destination, I turned the grand cherokee off. When I got back in the vehicle, the airbag light stayed on for at least 15 minutes then shut off. During the time of the air bag light on, I was able to press the cruise control and have it stay on the dash panel, but I still had no use of it. Once the air bag light shut off, I then pressed cruise control again just for it to flash on then back off. Now the passenger airbag light is flashing or stays illuminated when the vehicle is being used. My jeep just passed 125,000 miles. This shouldn't happen to sucha low mileage vehicle for the age.. Who will fix this mess?

A few weeks/months after the purchase of my jeep about 2 years ago, I noticed that my cruise control had stopped working and the ABS light had come. I checked my fuses and relays and they were ok. Then a day or so later I was driving on the interstate and my check engine light and my brake lights came on. My jeep then seemed to downshifted itself. It felt as if the transmission had locked up, it slowed to about 30mph and would not shift onto another gear. I pulled over killed the motor. After a few attempts to drive it, I turned the key over and noticed the break and engine lights were off so I attempted to drive home and was sucessfull. This started to happen more and more often. I noticed that it mainly happened when either I was running my AC or it was wet/raining outside. I then started researching jeep problems and recalls. I came across the daminoncrysler recall no. 13. The recall had described the issue I was having, so I researched my VIN and it staled that the recall no. 13 has already been completed on jeep. Now my jeep is stuck in limp mode and will not reset. It will not shift and the ABS, brake and engine lights stay on. Is there a way to find out exactly what service did they did when it was recalled in 2005 (if any)? I dont know what to do

In my 2005 jeep grand cherokee, while traveling on a congested road, approx. 25 MPH, I took my foot off the gas to slow down. All of a sudden, the vehicle accelerated on its own. Luckily, foot was on the brake hard. I attempted to tap gas pedal with other foot several times while trying to fight through traffic without crashing. I attempted to ease up on brake pedal while trying to pull car over, tapping on cruise control button, making sure that was off. In a state of shock, I actually turned the ignition key off, but the vehicle remained going. Soon after, I was able to reach the side of the road with the vehicle still wanting to accelerate and foot still on brake. This terrorizing episode lasted for under a minute before it ended as suddenly as it started. Due to the shock, I didn't realize I should have put the car in neutral. After a few minutes, I drove the car home very slow and cautiously, still shaking. I did not notice gauges on dashboard at time of the incident. The next morning, the car was towed to dealership. Diagnostic testing, test driving. No codes, no incident replicated. Throttle system checked and cleaned. No diagnosis found, suggest to change floor mats. I have driven vehicle for four years, no complaints. This is the first incident which scared the heck out of me. Vehicle has 37,500 miles on it. Having to pay for diagnostics and towing, we still do not know if it will happen again. My wife and I are both scared! Hopefully, it won;t repeat itself.

We have a safety issue with the adjustable gas pedal in our company car a 2005 jeep. The problem is that the pedal adjustment has no indicator that lets you know that the pedal has been moved by another employee. Recently we had an event were an employee drove the car a long distance and did not know that the jeep had an adjustable pedal. The employee complained that his foot cramped during the 300 mile trip and he did not know why. He was not aware of the adjustable pedal feature of the jeep since there was no indicator light or gauge to let him know that the pedal had been set for a much shorter person. The employee also complained that during this trip he found himself driving faster than the speed limit and had to use cruise control to maintain his speed...again he was not aware that the pedal had been moved closer to the driver and his normal position of his foot pushed the pedal down more then normal.

The automatic transmission of my 2005 jeep grand cherokee ,began acting unusual in mid november 2005. The transmission would clunk when put into drive , the vehicle seemed to hesitate before moving, also on 2 occasions the vehicle would down shift to first gear and then back to drive on its own while in motion. On december 18, 2005 I told the jeep dealer service manger of the problem when I took the vehicle in , I had received from daimler-chrysler a recall notice concerning the transmission , as far as I know the dealership performed the recall repair. The vehicle seemed fine until december 30, 2005 when while traveling on the expressway at 55 miles per hour with the cruise control engaged the vehicle again downshifted to first gear momentarily , all the warning lights came on then shifted back to drive the engine revved up and speed up unexpectedly . I then lost control of the vehicle spinning out and hitting the concrete divider wall of the expressway. The vehicle sustained over $10,000 in damage, luckily there were no injuries to me or my passenger. I have notified chrysler and my insurance company of problem, at this point I have not authorized any collision repairs to this vehicle. Chrysler said they would inspect the vehicle, I await to see what they will do. I don't intend to repair or drive this vehicle again or any jeep cherokee ,for that matter as to its unsafe transmission .
