Going down hill, the car accelerated 8 to 12 miles an hour faster than the cruise was set for. Car keeps accelerating until you hit the brake. Does not hold the set cruise speed limit. I brought it to the dealer and after 1 1/2 hours they told me my Cherokee limited was not equipped with an adaptive cruise control with stop and go. I was told by the service writer I just have to hit the brake until the decline is over and then hit resume on the panel. I know this is incorrect so is there a fix for this? we are taking a long drive trip to Pennsylvania and I will need the cruise to enjoy my trip. The consumer stated the issue was the transmission.

Transmission failed at 1,000 miles. Dealer replaced with a redesigned version. I started to get a wobble in the front end while I was accelerating. I brought it back and they said that it was a known issue and they were redesigning the front axles but the fix wasn't out yet. A few weeks later the metal frame in my sunroof broke and the weather stripping fell out and I couldn't close the shade. They informed me that the entire sunroof assembly had to be replaced because the frame was defective. The wobble continued to get worse and the car was shifting rougher than ever. I kept telling the dealership that there was something wrong, and they said "that's how the new 9 speed trans behave". when I brought the car in for the sunroof replacement I asked them to look at the wobble and trans again, and they informed me that the front axle was indeed bad. They put in the redesigned axles, and replaced the entire sunroof. I continue to have serious transmission issues and they put in a new valve body and updated the software. It's worse than ever. I kept complaining to Jeep and all they said was "the dealership can't replicate your problem." I actually had the service manager in the car with me and he verified that the car does not drive properly- and when Jeep called me, they told me that I had to go to another dealership. This car is not safe. It hesitates when you step on the gas, then it jerks very hard into second gear, it will accelerate on it's own because it can't find a gear to downshift, and the engine will spontaneously rev on it's own if I am descending a hill and its trying to downshift. The car will leap forward and accelerate until I press the brake hard enough to slow it down and it will finally shift. The rpms will go up for several seconds after I've applied the brake. The vehicle also rolls several inches after I put it in park now.

Less than 90 days after buying a new Jeep Cherokee I watched it towed away B/C it was un-driveable. It began in the morning when the gears were not shifting appropriately. Then a few hours later, the engine would rev, and car would speed up, even though I wasn't pushing gas pedal. Then reverse failed. Then the parking brake light came on. Finally, it stopped shifting up -- I had to floor it to go 5 miles an hour. I ultimately had to coast home.....updated 11/02/15 updated 11/02/2017

2015 Jeep Cherokee sport was purchased in October of 2014. Around end May 2015 experienced problems with braking. While coming to a stop sign brake would be pressed down but vehicles RPM's would rev up and vehicle would start accelerating forward. Vehicle was brought to shop after finally being able to make an appointment on 06/16/15. Mechanic was able to experience the problem and reset module on vehicle. But check engine light came on. Dealership gave vehicle back to us and we drove it for two more days and the problem still persisted. On 06/18/2015 a deer had entered highway and while braking vehicle again accelerated and hit the deer causing front end damage. Problem could of been 100 times worse because there were also bicyclists on road as well as tractor trailer traveling behind. Vehicle was brought to dealership via tow truck. Tow truck driver even stated there is something severely wrong with the vehicle. When driver took vehicle off flat bed he put the vehicle in reverse and the vehicle went forward instead of reverse plus the emergency brake came on by itself. Chrysler was contacted and they are doing an investigation on vehicle because of the severity. My wife and I just want them to take the vehicle back because we do not feel safe in it one bit.

My transmission keeps slipping on our brand new Cherokee we saved up for! engine light keeps coming on and it jerks a lot when trying to slow down. Getting into to car dealer asap! I'm so upset and scared to drive my two little kids in this car now that I think I know what the issue is. Whether they fix this or not. I don't trust this car now.

While driving 55mph check engine lite along with stop/start lite came on and vehicle rapidly decelerated from 55mph to 30mph causing transmission to over heat which ultimately lead to transmission replacement on a new 2015 Jeep,

Two incidents Jeep Cherokee was on automatic cruise control come to almost stop when front car took a right turn and this caused almost rear collision. I was like 30 feet away from the front car. Another incident: There was nobody around me and car applied brakes by itself and causes almost panic among the family members in the car and reduced the speed to 45mph.

Vehicle has extreme hesitation when accelerating from anything than a complete stop to the point in may stand you in between lanes of oncoming traffic, when the transmission shifts it will do so violently causing tire spin and loss of traction/control. Use extreme caution when driving. Jeep has been unresponsive to even admitting this is an issue.

- Spokane, WA, USA

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.
