Vehicle accelerated when put into reverse. Chrysler sent an "independant" inspector, but they will not share the report. In fact, chrysler lied about conducting the inspection. They told me the inspector could not do an evaluation because the vehicle was "disassembled". The dealer tells me the inspector spent two hours with a service technician and test drove the vehicle. I always get suspicious when someone lies to me. This requires follow up to make sure they are not hiding an unsafe defect in their vehicle.
2008 Jeep Grand Cherokee transmission complaints
Page 4 of 4: complaints 71 to 77 of 77, newest first, as owners wrote them.
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 !
Vibration at 45 miles per hour and above..
Tl*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.
