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 !

2008 jeep grand cherokee diesel 4x4. Power loss, hesitation, mostly happens at low speeds and gets progressively worse. The vehicle idles fine, then when you step on the accelerator to move out into traffic it sputters and doesn't proceed as expected. Very serious safety issue especially since the computer sees no codes so the dealer doesn't know where to start looking. It doesn't do it all the time and it's impossible to determine when it will do it.
