Also please check out the statistics and reliability analysis of Jeep Grand Cherokee based on all problems reported for the Grand Cherokee.
Transmission locks up after starting, unable to shift into any gear, and malfunction indicator light "mil" is illuminated. In order to get the vehicle to move it must be shut off and on, sometimes more than one time. After 4 incidents, Jeep gc was brought to local service dept. Where several flash updates were preformed to vehicles computer and valve body pump box was ordered. Jeep was returned for service 3 weeks later where transmission pump box was replaced and transmission re-trained. Since then the issue has continued to occur on 3 separate occasions. Additionally, now the diesel exhaust regeneration comes on every 30-40 miles where the car must continue to be run until regen has completed, no changes had been made to driving habits and prior to transmission work regen had never needed to come on. It is unknown if the Jeep gc can move when the mil and locked shifter occur as the issue has occurred only in flat areas (mostly home garage), however this could be a deadly issue if parked on hill and if vehicle transmission is not locking gears and can move forward or back. It does not appear that this is the case but can not be ruled out. Vehicle is going back in for service and transmission replacement. Based on research online it would appear transmission issues with the 2014 Jeep gc are widespread and even after repairs are preformed the vehicle never drives properly or as it did previously and usually hesitates, shifts hard or jerks forward which is also very dangerous as it seems to be sporadic and unpredictable for drivers.
