Driving at a speed of 60mph - all my instrument panel lights started flashing, the car loss all power and turned itself off. I was able to muscle car to shoulder. Put back in park and 2007 Jeep Grand Cherokee drove the rest of the trip (10 miles) with no other issues. Very dangerous situation! thankful there was not much traffic when this occurred.

I just recently purchased this 2006 Jeep Grand Cherokee 5.7 hemi with approx. 118,000 miles. Driving about 10mph in a parking lot, I stepped on the brake for a stop sign. When I went to go I got across the intersection then the vehicle engine revved up and I lost all propulsion power. I had roll to a stop, turn the vehicle off and then start up again to get things working correctly while in drive. It has happened again 2 other times at various speeds. Very dangerous when you lose your propulsion.

Speed control acceleration. Driving on interstate returning from vacation, cruise was set at 70mph. When approaching a slower vehicle, cruise was deactivated and reactivated when pass was completed. When reactivated the cruise control would not stop accelerating. This has happened 3 years ago and ever since I test the cruise control the problem of out of control acceleration persists. The out of control acceleration can be stopped by stepping on the brakes or manually turning off the cruise control. I had a mechanic look at it and they cannot determine what the cause is. I cannot even disable the cruise control without effecting other electronics. I am afraid to allow anyone else to drive this vehicle in the event they would unknowing use the cruise control and get into a serious accident.

"takata recall" when I click the cruise control it speeds up uncontrollably and I have to hit the brakes several times to disconnect it. It does not set a control at all and continues to climb in speed.

The check engine light would come on and the car would jerk at high speeds on the freeway, it even powered down completely on the freeway after reaching a high of 65pmh. The car would make strange grinding noises and lose power steering also. The vehicle was brought to the Jeep dealership and diagnosed finally after 2 visits as a faulty shifter module/control module or the cars "computer".

While driving and speeding up to switch lanes, the accelerator pedal was floored alone and the car took off speeding. I attempted to tap on the accelerator pedal but that did not work so I then pumped the brakes a few times before it slowed down. I was driving about 25 mph before attempting to switch lanes and when the pedal got stuck the speed went up to 60 mph.

Speed control accelerates out of control when set. Happens consistently when cruise is turned on and set button is pressed. The engine will rev to 6000 RPM +. must depress brake or turn off cruise switch in order to stop the acceleration. Started happening while traveling on an interstate highway and speed control was set to posted speed. Vehicle suddenly accelerated on open stretch of highway and could only be slowed down by turning off the speed control. This could have a disaster if it happened in heavier traffic.

Prior to the incident, my Jeep felt as if it were having trouble switching between gears. It felt jerky, if you will. While traveling along I-95 on the East coast of Florida, my Jeep (twice) slipped gear and appeared to have gone into neutral. If you know the area, it's not the ideal place for this to happen. Since returning to the West coast of Florida, it has happened once. I've taken to a shop for a tune-up and to check on that problem. Needless to say, the 'fix' did not fix it and I'm still experiencing jerky shifts and gear failure. I've read a number of similar complaints regarding the same type of incidents on the NHTSA website, but have not located a fix for the problem. Without hesitation, I'll say I'm terrified.

The contact owns a 2006 Jeep Grand Cherokee. While driving at an unknown speed, the vehicle stalled without warning. The vehicle was taken to an independent mechanic. The technician stated that the vehicle was operating as designed. However, the failure recurred. The vehicle was taken back to an independent mechanic, who confirmed that the alternator needed to be replaced. The vehicle was repaired, but the failure persisted. In addition, the contact stated that the engine revved without depressing the accelerator pedal and the check engine warning light illuminated. The vehicle was taken to an inspection station. The technician diagnosed the vehicle, but failed to specify the repairs that were made. The vehicle was not repaired. The contact received notification of NHTSA campaign number: 14V438000 (electrical system); however, the part for the recall repair was unavailable.

Incident happened multiple times. Engine, shut down briefly. When I stepped on brake it vibrated severely. The instrument panel lit up, was unable to steer. Received notice from NHTSA tried to have fixed several timesand part is still unavailable. It is happening more often and I am afraid to drive it. Very disappointed. I believe Jeep should furnish me with a safe vehicle.

Grand Cherokee 6-cyl

  • 40,000 miles
While driving on a highway, I noticed my car slowed down and even after applying the gas pedal, it didn't help. After pressing the brakes and pushing the gas pedal again, then it started accelerating. The engine light would blink and lately it stays on. The check engine light stays on and off but once I noticed that when I started the car again, the check engine light was off but I lost one front headlight. I was told by the dealership that I needed to replace a spark plug which cost me almost $300. Now the check engine light is on again and I suspect as other owners have shared it in the forum that it's the ignition switch that's faulty. I just wish NHTSA would do something about this asap. The letter came the mail stating there is a recall on my car but nothing is being done to correct the problem. Are you waiting for severe accidents to happen before you really force Jeep to correct this issue"?? do people have to lose their lives before you act on this problem"

I bought the Jeep in Feb. 2013 and shortly thereafter, while driving on the interstate, the car just shut itself off and everything went dead. This has happened about 2 dozen times since, sometimes going fast and sometimes going slow or pulling into an intersection. There doesn't seem to be a factor that causes it to happen and the mechanic cannot find anything wrong but it is very dangerous.

Random incidents while driving the dashboard will light up with all indicators and gauges go to zero value. I recorded on my cell phone one incident. I had one case that Jeep stalled at same time of incident, and I was able to coast to side of road, shut engine off and restart. I discussed this with local dealer and they could not obtain any error code. I called Chrysler on one incident and they said they had no known problems reported on my vehicle. Dealer said to return next time it happens but I am always not in a convenient place and the dashboard will return to normal status after some time while driving.

While turning right into a parking lot at low speed, my knee brushed the key chain/key and ignition turned off while still in drive. Has happened once more in the last month in a similar circumstance, both luckily at low speed in empty parking lots. Had to shift to park and restart engine to regain power/control.
