Shortly after changing the spark plugs in my wife's 2007 Grand Cherokee overland the vehicle would stall on deceleration. I thought it might be an isolated incident, but the stalling continued frequently. The engine completely shuts down and the vehicle must be stopped or put in neutral while coasting to be restarted. After conducting some internet research I found this to be a common problem with the 2007 Grand Cherokee with hemi's. I was amazed at the number of occurrences of this happening among this vehicle. There are Jeep forums (www.jeepforum.com/forum/F67/2007-Jeep-grand-Cherokee-overland-stalling-problem-1147825/) that discuss this issue in depth. The vehicle stalls less frequently than it did when I first changed the spark plugs, but it still happens. The most recent occurrence was on November 1, 2013 when my wife was picking my son up from school. Chrysler corporation fails to take a stance on the problem denying that the problem exist. I have spoke to my local dealer's service department about the problem and they denied any knowledge of it. I would sale the vehicle, but in good conscience I could not do that to another individual. Several dealerships have replaced the upper and lower wiring harnesses on several vehicles and this seems to have resolved the problem. Again to restate the problem it seems to occur after the spark plugs are changed in the vehicles. This would lead one to believe that disturbing the position of the wiring harness effects the vehicle. Chrysler no longer manufacturers that wiring harness, as they are on the third version of it. This in itself would lead you to believe that Chrysler has some knowledge of a problem, but will not issue a recall or take any official position. My main concern is for my wife and children's safety while riding in this vehicle. I ask that you please take an in-depth look into this situation.

Driving at night, doing 50 mph when vehicle engine cut off - could not pull off road, apply brakes or steer.towed in. "repaired by dealership" only to occur again in 6 days when engine would not start at all. Again, sent for repair, five days in shop. Occurred again the very next day - would not start. Has been at dealership another week and they still have no solution to problem. Husband is totally disabled and we must have a dependable vehicle. We bought it used with only 37,000 miles on it so we thought it would be almost new. Cannot take a chance of the engine cutting off while on a busy highway!

The contact owns a 2007 Jeep Grand Cherokee. The contact was driving approximately 30 mph when the vehicle would no longer accelerate and came to a stop. The check engine light was illuminated and the steering wheel became abnormally stiff. The contact was able to move the vehicle to the side of the road and turned the ignition off. When the contact restarted the vehicle, the vehicle jerked but the contact was able to drive the vehicle to his residence. The failure persisted at least sx times and the vehicle was taken to the dealer where the technician advised that the transmission module control would need replacing. The manufacturer was contacted and advised they would work with the dealer in assisting with repairs. The vehicle was not repaired. The approximate failure mileage was 27,600.

Car will decelerate, and will not respond to depressing of the accelerator pedal. Occurs at various speeds and traffic conditions. Contacted dealership, began to describe issue, without describing the make and model, and the repair-shop was able to then tell me the make and model of my vehicle without me previously disclosing. (already had gear shift module replaced once before, and since the issue occurred 14 months later, dealership refuses to cover expense of replacement.) this is a very dangerous issue, and as stated before, occurs at various times and traffic conditions, and there are no preceding warnings or other indicators that foreshadow the occurrence. Car is now at 42,000 miles, yet it is in need of a 3rd shift module, seems highly unlikely. Dealership needs to declare a recall or when the customer has the problem, they fix it without further expense to the consumer. I bought this Jeep new, and its my 4th one, however, I am extremely disappointed with their customer service, and the quality of vehicle they are producing, and will not ever purchase their vehicles again.

Funny noise making right turn like wheel rubbing. Thumping noise at low speeds from brakes.

- Norcross, GA, USA

The contact owns a 2007 Jeep Grand Cherokee. When the contact turns the steering wheel all the way to the right, the inside of the tire would rub against the stabilizer bar. He could hear a growling noise, which alerted him to the failure. The dealer could not find any failures; however, they advised him not to turn the steering wheel all the way. The contact believed that this could not be avoided. The manufacturer informed him to get his vehicle inspected again. He took the vehicle to another dealer and they stated that the front carriage was off center. The dealer adjusted the centering and realigned the front end. After a few days, he turned the wheel again and heard the growling noise. The current mileage was approximately 22,900 and failure mileage was approximately 20,000. Updated 12/11/08. The manufacturer told the dealer to replace the stabilizer bar. Updated 12/11/08.
