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.

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.

When downshifting there is and abrupt shift in the 18-22 mph range. With icy roads this could cause the driver to lose control of the vehicle and cause serious personal injury.

- Kalamazoo, MI, USA

The contact owns a 2015 Jeep Cherokee. While driving at a low speed, the accelerator pedal was depressed but the vehicle failed to accelerate. The malfunction light and service transmission light remained illuminated. The vehicle was taken to the dealer on two separate occasions. The technician diagnosed that the transmission computer needed to be re-reprogrammed. The vehicle was repaired; however, the failure persisted. The vehicle was taken to a dealer a third time where it was diagnosed that the valve body needed to be replaced, but it was not repaired. The manufacturer was notified of the failure. The failure mileage was 930.

- Staten Island, NY, 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.

- Janesville, WI, USA

The contact owns a 2015 Jeep Cherokee latitude. The contact stated that the traction control system would erroneously activate each time the driver's foot was taken off the accelerator pedal, followed by a warning chime. When the failure would occur, the transmission could not be used in reverse. The contact also indicated that while stopped at a red light on a slight incline and secured in drive, the vehicle would roll in reverse. The failure recurred also on a flat road surface and while the vehicle was stationary. The vehicle was taken to the dealer but no information regarding the cause of the failure was made available to the contact. The manufacturer was not notified of the failure. The VIN was not available. The failure mileage was 450. Mailed out 01/13/15

I am filing this complaint about my 2015 Cherokee latitude because the vehicle was repeatedly shifting itself out of drive into neutral while the SUV was in motion. I had the vehicle for 12 days before this happened. I was compelled to file this complaint for two reasons. First, in doing minor internet research about this problem, I discovered this was an ongoing issue with the new 9 speed automatic transmission that Chrysler was aware of way back in October 2013 and was "supposed? to fix with the 2014 model & subsequent models after that. I have a brand new 2015 model and this issue has not been properly addressed & fixed at all. It"S obvious that the proper amount of qa was not done if this is still happening. Secondly, the main reason I wanted to file this complaint it because this issue of shifting out of gear while driving is a critical one. I am extremely lucky that I was not involved in a collision with a vehicle driving behind me when my SUV suddenly & repeatedly stopped moving. My concern is that other drivers with these new 9 speed transmissions may not be so lucky. This issue could easily result in injuries or death if not properly addressed.
