2007 Jeep Commander 4x4: adaptive cruise control problems

Filed Mar 23, 2015 · Engine · 92,000 miles · CA

I have owned this vehicle since new and have been experiencing infrequent and usually momentary engine stalls while driving at highway speeds for years. Each time there was a slight clunk sound and lurch forward - as if the cruise control had just disconnected, and within a second or so everything would be back to normal. But on a recent trip I had three incidents over two days which were much worse, perhaps because they all occurred at temperatures around 0 degrees f.or below. In two incidents, while driving on an interstate at a steady 75mph, instead of the engine immediately recovering, it took long enough that the vehicle had slowed down to 30-35mph before the engine restarted itself. In one incident also while driving at a steady 75mph on an interstate the engine did not recover and I had to pull off onto the shoulder and come to a complete stop with no power. I turned the ignition off and then on again and the engine restarted immediately. I had no loss of electrical power during these incidents, and I have nothing dangling from nor could I have bumped the ignition key. I have always maintained the vehicle according to the service schedule and have had all recalls performed, with the exception of the latest one for which the dealer still has not received the parts from jeep. I took the vehicle into a jeep dealership the same day as the second and third incidents and they said they could find nothing wrong. I asked them if possibly the power controller module recall needed to be done a second time, and they responded that jeep would not permit that.

Cruise control still does not operate. Single touch power window function no longer works on driver and passenger windows. While commuting to work on the toll road, rpms registered between 2500-3500 going at a speed of 75. The majority of the time, it was between 3000-3500. I did not have the air conditional running. I was not accelerating and was not going up or down inclines to cause the higher rpms. After exiting the toll road, I turned and while accelerating to around 40mph, the engine stalled and the check engine light came on. As I was on an inside lane, I had to slow down to allow a semi to pass on the outside lane in order to be able to pull over to the side of the road. I had to place in park, turn off the ignition switch, and turn it back on. Check engine light remained on. My average mpg was 13.9, lower than it should be. Leaving for my commute home, when I turned on the jeep, the check engine light was no longer lit. I noticed during the commute that the rpms were not as high as in the morning, and also my mpg increased by almost a mile per gallon, and that was running at the same speed and I also was running the air conditioning. Upon exiting the toll road, the vehicle jerked heavily while downshifting from overdrive. A jerky motion continued for the remainder of my commute (ranging from 30-55 MPH). Please note that I do now take photos after the engine stalls to reflect the mileage and that the light is lit. I also now take pictures when the check engine light goes off.

While idling in a driveway, the check engine and esp/bas lights came on. The vehicle did not stall. Shortly afterward, when driving about 55-60 MPH, I realized the cruise control no longer works. I tried multiple times to turn it on, but it does not come on any longer. The esp/bas light went off about 10 miles later, after I stopped to fuel up the vehicle. The check engine light remained on. About an hour later and another 35 miles later, after making a stop, the check engine light did not come back on when restarting the vehicle. Later in the afternoon, while it was in the neutral gear and going through an automatic carwash, the vehicle stalled twice. The rpms were constantly up and down between 500 and 1500 rpms.

I purchased the 2007 jeep commander with the 5.7 hemi in spring 2013 and a few months later coming to a stop it just shut off. At first I thought maybe some water had gotten into the engine compartment since it was raining and shorted something. Started back up and thought all was fine. Well recently it has been happening more often, whether it is wet or dry out and at any speed or whether the cruise control is on or off. It also seems to try to shut down while feathering the gas pedal at highway speeds from accelerating to coast. On one occasion this summer at highway speed pulling our camper it shut down and I had to coast to a stop along the side of the highway to restart. Something has to be done. I have children, as I am sure many here with the same complaint do.

Tl*the contact owns a 2007 jeep commander 4x4. On september 10, 2007, while driving 70 MPH, the vehicle shut off without warning. The cruise control was engaged at the time of the failure. The contact stated that she was decelerating and the wheels and brakes locked up simultaneously. The vehicle restarted approximately 15 minutes later. Another failure occurred when she placed the vehicle in reverse. She stated that the vehicle failed to move while the gear was in reverse. She took the vehicle to the dealer and they stated that the fuel pump failed. The vehicle is currently being repaired at the dealer. The contact only had the vehicle for thirty days before the failures began. The current and failure mileages were 2,436. Updated 09/26/07
