The contact owns a 2008 Jeep Grand Cherokee. While stopped at a red light, the vehicle began to shake and lose power. The vehicle was taken to the dealer to have the pcm programmed. The pcm did not stop the shaking; however, the vehicle no longer jerked forward. The vehicle has been at the dealer five times for the shaking issue, but they cannot remedy the failure. The contact feels that this is a safety issue because the shaking and jerking almost caused a crash. The current mileage is 11,700 and failure mileage was 5,514. Updated 6/4/09 the rear view mirror was out of frame, the engine had a rough idle and it felt as though it was going to stall. Updated 06/09/09. The consumer she and her husband were displeased with the arbitration boards' decision. The consumer stated the vehicle would surge forward and vibrate when at a stop and would feel as though the vehicle would stall, even more without the air condition turned on. The explanation the consumer was given that the air condition will cycle on at the same time the cooling fans which was said to cause the problem. Updated 11/02/09.
2008 Grand Cherokee 4x4 4. 7l flexfuel stalling at various highway speeds. Throttle lagging, harsh up/down shifting, hesitation on torque demand, fuel mileage reduced by 20%. After the first two stalling occurrences, the dealership replaced the fcm (front control module) since the serial number of the installed one-337- matched the February 2008 recall, although Chrysler database VIN recall search came back empty??!! the third and fourth stalling events were followed up by the replacement of the pcm (powertrain control module) since a "soft fault"-"torque request denied" was found stored within the controller. However, after six hundred miles, a fifth stalling occurred. This time a hard fault related to the map sensor (intake manifold absolute pressure) was found. The replacement was scheduled in 48 hours. There were six dealership appointments(only two documented though ??!!) and it was invariably either "we have to order the part" or "there is nothing wrong we could point at". The almost new vehicle is not safe to be driven on public roads. Yet Chrysler never provided a temporary replacement until the safety hazard could be located and eliminated. After every attempt of solving the problem, the customer is sent away to try his (her) good luck with a vehicle which might be okay. I don't think this a professional approach for both Chrysler and the dealership servicing the vehicle. Guessing and safety does not belong within the same sentence !.
