My parents purchased a brand new 2008 jeep grand cherokee limited. I was driving the vehicle on july 11, 2008 in my neighborhood to pick up some food with my 8 months pregnant sister in law. As I drove the vehicle it accelerated without me pressing on the gas and I lost control and the vehicle hit approximately 3-4 parked cars, I landed in the trunk of another vehicle, on top of it. If it wasn't for the vehicles parked, I don't think the jeep would have stopped. Luckily no one was hurt badly and the airbags were not even deployed. This incident has really affected me and the way I drive. I do not even like to be a passenger in jeep vehicles anymore. In january, 2010 my mother dropped her car off at a garage to have it parked. She was called from the garage that the vehicle had been in an accident. The vehicle once again accelerated in reverse and there was damage to the vehicle as well as the garage. Jeep cherokee's are extremely faulty, always in the dealership with some issue. This is not a coincidence. This needs to be taken seriously. People can lose their lives if these vehicles are not recalled.

While sitting at a stoplight, on two (2) occasions my 2008 jeep grand cherokee 4x4 suddenly accelerated on its own while my foot was on the brake and revved up (throttle surge), then the tach went back to normal, and the engine went back to idling. Took it to the dealer I bought it from, they checked the on-board computer and no incident showed; they told me they called chrysler but no one has reported this before and no technical bulletin has been issued regarding throttle surge issues. Have only had the vehicle 11 months. Now at times, while stopped and idling, the engine will act like it's going to cut off as the idle drops for a few seconds. Dealer also did not find an issue in the computer with this problem when I took it in a second time.

Sudden acceleration/ loss of brakes. Vehicle accelerated to full throttle while entering from freeway onramp. The driver took foot off accelerator and vehicles accelerator pedal continued to move downward to full throttle and would not decelerate after an attempt to "pump" the accelerator pedal to try and get the pedal to release. The automobile was then put in neutral and the engine would not slow down in" RPM's". The brakes were applied and an attempt was made to stop the vehicle and the brakes were not functioning properly with the automobile coming to a very long and slow stop white trying to maneuver the automobile to the side of the road. Once the vehicle was brought to a stop the motor was still at an extreme "RPM" level. The motor was turned off at the ignition switch and the engine finally stopped running. After sitting at the side of the road for sometime the vehicle was restarted and driven to a safe location where the driver let the vehicle sit for an hour or two and restarted for the final drive home(about five miles). The vehicle was taken to the dealers service department the next business day. The dealer ran a scan on the vehicle and diagnosed that the event occurred as stated. The dealer consulted chrysler service center and were recommended to replace the throttle and brake modules for the sudden acceleration and braking problems. The vehicle parts are at the dealer with the vehicle. The vehicle was test driven by the dealer and the customer was told the vehicle was ready. When the customer asked if the vehicle was repaired and safe the service department representative said "we installed the recommended parts by chrysler service" and would not say if the vehicle was repaired properly or safe from the sudden acceleration/brake problem. The vehicle as of today 12-24-2008 remains at the dealer.
