The contact owns a 2015 Jeep Cherokee. While driving at approximately 65 mph with the cruise control engaged, the vehicle accelerated without the accelerator pedal being depressed. The failure occurred while traveling downhill and recurred numerous times. The vehicle was taken to a dealer where the failure was unable to be determined. The manufacturer was made aware of the failure. The failure mileage was approximately 100. Updated 8/10/15

I was turning into my driveway and slowed down before hitting the slope, when I pressed the gas pedal to go up the driveway the engine revved up but the car didn't accelerate. After about a second the car jerked and sped up faster than normal to where I had to slam on my breaks to avoid hitting the garage door.

I purchased a 2015 Cherokee sport in October 2014. Since then I have noted several recurring problems. Having never owned a brand new I thought perhaps there was some early mile growing pains but these problems persist. The screen malfunctions at will; sometime the rear camera is engaged when driving forward, the screen locks on the disclosure/acceptance page. Voice recognition/command has never worked. Unintended acceleration when at a complete stop (reminds me of an unruly dog on a leash trying to leap forward). Delayed acceleration when the gas pedal is depressed causing it to suddenly leap into motion risking hitting a car in front of you in city traffic (I live in los angeles ? this is particularly concerning) or a wall behind you (I back into my parking space). When parallel parking or in a 3 point scenario (D-R-D) the car, although clearly placed in the reverse the car will roll forward before reversing. Often putting the car in reverse, waiting several seconds (4 to 5) before releasing the break will do the trick but just as often, it makes no difference. Gear transitions are sloppy. This car does not shift it lunges. I'm surprised the [xxx] thing doesn't bite although it tries. I thought these were my pet peeves but it appears I am not alone. I wish I had read these earlier complaints. I would have returned it to post haste. I hate this car but am not in the financial position to buy another. Purchased from a dealer 50 miles away (best price) has made it difficult to take into the dealership. I have finally scheduled 2-days off from work to take it in. I wish I was in the position to not just drop it off but leave it there. If I had the money I would not hesitate.

I bought my Jeep one month ago. Recently I noticed that engine revs up and accelerates by itself as I am trying to stop. I have to control this by pressing the break a little harder. I am afraid I will rear end another car. I had no idea this problem was so common. Now I wish I hadn't purchased this vehicle.

My vehicle instantaneously picked up speed while I was coming to a stop; my foot was not on the gas pedal. A quick jerking motion of the steering wheel happened quickly with the acceleration. This caused me to press much harder on my brakes to stop my vehicle from hitting a car in front of me. This is a dangerous and very scary problem and I am grateful to not have caused harm to anyone. My gas consumption varies because of the required pedal pressure sometimes needed to accelerate since the gears seem not to switch over as they should. Also, my radio has been blacking out, turning off and on, and failing to work at all. Have an appointment with the dealer tomorrow for what was explained to me as a needed "software update." This is a new truck. My Jeep has not yet made it to the required miles for its first oil change. (sigh).

Car lunges forward when decelerating. Need to press hard on brake to control speed.

- Beachwood, OH, USA

The check engine light goes on and the car does not downshift properly. The engine revs up over 2500 rpms and the vehicle accelerates on its own when applying the brakes and trying to slow down. (last night the car revved up to 3200 rpms when coming to a stop.)

- Newtown, CT, USA

While braking at 24 miles per hour the car abruptly downshifts and causes the vehicle to accelerate. I have noticed the longer I drive the vehicle, it will happen while I am slowing down at higher speeds at well. I have taken the Jeep to the dealership and they have flashed and updated my transmission but they said it was fixed but it was not. It is acting up more than it was before. It is incredibly dangerous to drive this car especially when trying to brake around a curve because it will speed up by itself.

- Smiths Station, AL, USA

Vehicle was traveling on interstate highway when service transmission light came on in the stored messages, then the malfunction indicator light and service engine light came on. Within minutes, driveability issues became apparent with no acceleration and slipping gears/unable to shift into gears. Once the car slowed/stopped, the vehicle was unable to shift into lower gears to move. The vehicle had received the P56 recall to update the computer software to the transmission control module one month prior to this incident.

The vehicle was taken to the dealer who did not determine the cause of the failure. The manufacturer was notified but not solution was offered. The VIN was not available. The failure mileage was 23.
