The contact owns a 2015 Jeep Cherokee. The contact stated that while decelerating in order to come to a stop, the vehicle would experience unintended acceleration and lunge forward. The vehicle was taken to the dealer who diagnosed that the transmission was faulty. The transmission was replaced and the transmission software was updated but the failure continued to occur. The vehicle was taken back to the dealer who replaced the transmission a second time and updated the software but the vehicle continued to experience the failure. The manufacturer was notified of the failures. The failure mileage was 300.

When braking to a stop the vehicle suddenly accelerates launching it forward with the brake applied.the transmission slams into 1rst gear just before coming to a stop after that making the vehicle slide to a stop. The problem continued to get worse. Was told by dealer on 2/10/ 2015 that surge was inherent in these vehicles with this trans missions. There are no check engine lights on or warning lights for this problem.we have been pushed trough intersections in front of logging trucks and narrowly missed getting hit, the last time we hit a snow bank across the road at a 3 way stop and damaged the front spoiler when we bounced off. The 2nd problem is the complete loss of power with the engine running, it will stop going forward at any speed and will not accelerate even to the floor. The engine remains running but there is no go.the only way to get going is to stop, turn off ignition and restart. Then it will only go a few miles and do it again.the service transmission light come on when this happens.we lost power at an off/ entrance ramp on the freeway and could not get out of the way on an overpass with no shoulder as it was banked with snow.again we narrowly missed by large trucks and other vehicles. That was the first time this problem started and found out you have to shut the vehicle off to regain power, but that only last for 10 minutes of driving till it does it again.the vehicle was taken to don's auto clinic in Cadillac Michigan March 2nd, they called and did a computer recall up date and took it for a test drive and it launched the tech through an intersection also. There were no codes for the incident and they have contacted Chrysler about the problem. I told the vehicle is dangerous and can not be drove safely. The last incident happened on 3/1/2015.

2015 Jeep Cherokee 2.4L. Jeep has less than 200 miles. Car was brought in for service due to sudden acceleration while decelerating at approximately 25 mph. Car would slightly accelerate and the RPM's would jump from around 1400 to 2000 without my foot on the gas pedal. Dealer service department had the car for 1.5 days and said that I had the most recent "flash" after driving off the lot the issue still exists. Car will lunge/accelerate and RPM's jump while decelerating and foot is off the gas pedal.

It appears I've gotten the transmission bug that seems to be going around. One month old 2015 trailhawk V6 automatic with 738 miles on it. Started the car(2-7-2015) and notification came on dashboard that read, "service transmission, " "4WD deactivated, " "remote start deactivated, ' "and put car into park then shift to desired gear." I managed to get the Jeep rolling and drove directly to dealership. I talked to the service rep this morning(2-9-2015), and before he could say anything, I told him it was the tcm. He actually laughed because I knew every problem. I guess best case scenario is that the reset works. If not I'm sure there will be a tcm replacement. Worst case scenario is the transmission needs to be replaced, and at that point, they can keep it.

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.

2015 Cherokee latitude 4 cyl. Have had vehicle for 2 months, during this time the transmission has had a mind of its own. Accelerating during braking, which in and of itself is extremely dangerous as it has happened while slowing to make a turn, if you need to turn at 10 mph and the car accelerates past 25 you are looking at an accident waiting to happen. Lag in downshift while trying to accelerate, loud un explained clunk while placing into park, numerous engine warning light activations. Called local dealer and was informed that I needed to wait a few days to see if warning light resets itself before bringing in. The transmission never seems to actually shift into 9th gear, which inturn hampers the fwy mileage claims associated with this vehicle. Ive noticed the transmission temperature exceed 240 degrees on numerous times, this cannot be good. I will be taking vehicle to dealer, hopefully in an effort to get this resolved. With all of the reviews and problem, will it take an unfortunate fatality for Chrysler to actually resolve this, as in the case of the Toyota acceleration problems?

Transmission down shifts on downhill at times. RPM increases and vehicle speeds up before completing the down shift. The trans. Should not be down shifting on its own in this situation. This will be dangerous in snowy conditions, as the shift is unexpected. The trans. Is inconsistent on level driving. Sometimes it picks gear 7, other times it picks gear 8. this affects gas mileage and cannot be over ridden by using the manual shift mode. I am at the mercy of the transmission. The manual shift override is virtually useless. I cannot override the gear selected. The indicator show only shows the shifter actions. I does not indicate the gear you are actually in. The trans. Does not respond to manual shifting preferences. It will be dangerous in winter weather when you cannot depend on a manual downshift to maintain control of the vehicle. I am used to other manufacturers transmissions that lock in and hold the manual gear selected. I suspect that there will be Cherokee accidents in winter weather due to loss of control, because the transmission either has a mind of its own which is inconsistent, or because manual transmission control is ineffective, and nonresponsive.

When idling after a 20 minute drive, the "service transmission" warning and the "check engine lamp" came on and wouldn't turn off. I managed to drive slowly home - it was about 20F and snowing - in a deserted area. Very bad situation.

This 2015 Jeep Cherokee limited, with V6 engine and 9 speed automatic transmission, operated smoothly for 750 miles, but then suddenly the transmission began to downshift very roughly when coasting to a stop or braking to a stop. The problem appears to be with the shifts below fifth gear. When coasting, as the downshift to either 4th or 3rd gear occurs, the engine revs and the car actually accelerates briefly (for 1 or 2 seconds) on its own. In heavy traffic, that makes quickly applying the brakes mandatory to avoid getting too close to (or hitting) the car in front of you as the vehicle accelerates.

- Kirkwood, MO, 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.)

When driving the vehicle, dash lights would flash and check engine light would come on. Messages would state the there was a failure with the start/stop or 4X4 or transmission. Vehicle would not engage any gears, D (drive) indicate would be flashing, and I could only rev the engine. Vehicle would not advance and would not engage any gears. Had to shut off engine and turn it back on several times to get the transmission to engage. Check engine light is still on. Taken in for service four times now, update firmware, replace PCM, and now they are going to replace the wiring harness. Vehicle purchased on 12/31 and has been in for service with major failures with the transmission since 1/13/2015.

- Livermore, CA, USA

2015 Jeep Cherokee latitude. When coming to a stop, at about 25 mph, the tachometer reads 1250 RPM then the transmission drops out of gear which makes the vehicle speed up, making me brake harder, then the transmission downshifts and the engine revs up to 2000 RPM making the car lurch forward. This is dangerous and has made me feel like I may rear end a car on several occasions.

As I was getting off the freeway, the vehicle was down shifting, and as it got to the lower gears, started getting very jumpy. When it got to first gear, it seemed that it downshifted all the way into neutral. When starting from a dead stop, the vehicle would jump into first gear and was jumpy shifting up gears. I took the vehicle to the dealer, and they told me the transmission needed to be replaced. They also said it was still drivable. I was out of town at the time so I just planned to take it to my local dealer when I got home, as they said it would be about a week before a new transmission was available. I left the dealership and didn't make it more than a mile before I lost all use of the transmission, and had to be towed back to the dealership. They have since replaced the transmission.

When coasting or coming to a stop, Jeep will accelerate/jump forward while in 4th gear. This is very dangerous on icy roads.

Loud noise from the engine/transmission then the car completely shuts down and comes to a complete stop in the road. The car will then restart all systems with check engine light on. Has happened and been taken to the dealership for repairs on 10/20/2014, 12/1/2014, 12/3/2014,12/12/2014,12/22/2014. Dealership nor Chrysler know what is causing the issue and will not do anything except try to repair. I have concerns that if this issue happens at higher speeds on interstate what would happen.

- Kingsport, TN, 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.

Have had two times the vehicle transmission warning came on to "service transmission" with no response from depressing the accelerator. At these two times the vehicle was at a full stop and the dash was full of warning lights for different things. When the transmission was shifted from drive to park, there was a loud and violent jerking by the transmission. This transmission has had it's software updated many times, which has not helped. Dealer tech was able to observe this condition and replaced the transmission valve body. After replacing the valve body and after driving about 50 miles on a interstate highway, the service transmission warning came on. Took the next exit and stopped at a traffic stoplight, the car would lunge and jerk violently trying to go. Shut the engine off and let the car reset itself. Will not drive the vehicle again and will ask Chrysler to supply a rental vehicle at their expense until they have replaced my vehicle. This makes three times the vehicle has been in the shop for transmission problems. This transmission issue as far I am concerned is a major safety issue.
