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.

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.

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.

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.
