Vehicle will stall without warning. Has occurred at least six times over the past three months. The stall as occurred at speeds as high as 45 miles and hour. The vehicle has been taken to the dealer four times in the past six weeks for the same problem. The dealer has given us push back when we schedule another appointment because they cannot diagnose the problem. Our last appointment scheduled January 31,2009 they never even looked at the vehicle. The car stalled again at 45 mph almost causing my wife and seven month old to get rear ended.

I have been having a stalling problem for a couple months now. When I am at a stop sign or red light, my car will start to idle very low and then completely die. It will restart when I put it in park and turn the key again. The next time I try to start my car after it stalls, it usually takes about 10 seconds for it to start when turning the key. My car has done this 5 times now. It happens about once a week. My car also idles very low, very often when I am stopped. It does not stall everytime though. Everytime it happens I take it directly to the dealership. The dealership keeps telling me nothing is wrong with my vehicle, and they don't know why it would be dying when stopped.

I am driving a 2007 Jeep Grand Cherokee with the 3.0 L diesel engine. Complaint: When I was driving on the highway in the left lane my Jeep stalled and as I was trying to change lanes I almost got hit. I lost power and it was hard to steer the car and ended up having to push the car with some help to the curbside. I was not able to restart the car. I know the Jeep has a Mercedes Benz engine just like other Mercedes that now I have also heard 2007 Mercedes benzes with the same exact diesel engine have already been recalled. Please note that Jeep, with the same engine is having same engine problem and please recall so that people are not in danger. It was a very scary day, I could have been injured or lost my life or my childs life or another family. This was very dangerous and I am not feeling good about this engine on the road. Thank you for addressing this issue.

2007 Jeep Grand Cherokee, new, 6,000 miles, stalled at stop light.

- Naples, FL, USA

I purchased the car from a 5 star dealership in antioch at an auction. After driving the car for about a month it would refuse to start. There would be times when I would stop and turn my car off and then the engine would not work. Sometimes I would be put in an unsafe situation and it has happened about 8 times. Each time it happens I call the 800 number and have Jeep tow my car, which is still under warranty, to the nearest Jeep dealership. Each time it has been there they have changed module in the engine and within the transmission. The engine has been taken apart and still the problem persists. My car is currently in the repair shop again and it has been extremely frustrating. I brought up lemon law, however, they tell me that since I am the second owner this clause does not apply.

Without warning while driving 2007 Jeep Grand Cherokee with crd (common rail diesel) engine with about 4,000 miles on odometer under light load in light traffic with about 3/4 tank of fuel on a hilly rural highway at about 50 mph the mil ("check engine light") turned on and within a second or so, if not simultaneously, the red error light indicating malfunction in the electronic throttle control system illuminated and began flashing. Driver immediately slowed to 30 to 35 mph, activated emergency flashers, and changed route to return vehicle home, at that point about a 15 mile trip on a combination of hilly rural highways and Suburban arterial roads. About 10 miles later while climbing a hill in a blind curve on a rural highway with no shoulder in moderate traffic at about 35 mph the engine stalled bringing vehicle to halt. In the shoulderless blind curve there was neither visibility nor room for following traffic to pass, thus creating an extremely dangerous condition. Driver was able to restart vehicle but it then seemed to operate in "limp home mode" and did not seem able to move faster than about 20 to 25 mph before stalling again. Vehicle then stalled repeatedly in the last 5 or so miles back to home on hilly rural highway in moderate traffic, and restarting attempts became progressively more difficult. By the time vehicle was returned to owner's property the engine would not start except to run for a few seconds before shutting off, and vehicle having become completely undriveable then had to be pushed to a safe place to await tow to selling dealer for service. Driver contacted selling dealers service department to report problem, and service appointment and tow to selling dealer are pending.

The day after I bought the brand new 2007 Jeep Grand Cherokee diesel, I unlocked the doors with the key fob, opened a couple of the doors and loaded my luggage, then I did the key sequence on the keyfob (lock+panic) to turn off the beep when you lock the car. After all this I tried to start it (correct starting procedure - wait for glow light to go out) and the starter cranked the engine with no firing at all. I repeat and wait 5 times over about 5 minutes, it failed to start each time. Finally after I have waited about 2 more minutes, I tried again and it fired right up like it is supposed to. I am concerned the car could fail to start again. Updated 01-16-08.
