The new 8 speed transmission is awesome but had an issue with hard/jerky downshifts. Dealer did a software update per TSB# 21-017-14 and it shifts perfectly now. No problems since the TSB was performed
Replace rear axle due to electrical wire holder breaking and allowing the cable to drag on the axle boot. Caused a grease leak and ruined the joint.

Jeep would not go into gear, have to move back and forth to get it in gear. Performed BCM flash per RRT 14-050 18-19-02-P9 Module , body control reprogrammed.
Service 4WD light and warning indicator. Dealer found problem is actuator and motor (?) faults/failures, and needed to order replacement parts. Parts (hopefully) received to complete repair of 4WD actuator/motor issue.
Transmission overheats when towing an RV weighing less than 3,500 lb. Vehicle is rated to tow 6,000 lb. Updated software.

Transmission reflash. Still needs work

Updated "flash" on 8 speed transmission. TSB repairs: updated flash on transmission,replace overhead map light, install moisture protection boot on master brake power unit.
Wife received Service 4WD Message. Dealer replaced 4WD transfer case control module. Tested another 160-170 miles and returned car to us as fixed, safe. Service 4WD Light on again. Car stereo/Nav was cutting out while driving back to dealer -- this is what happened when car first died. Car is still at dealer at this point, we are filing for Lemon buyback.
Dealer replaced Transfer Case and selector switch - something about clutches being too tight as determined by Chrysler STAR engineers. Vehicle has been as designed since then, but was in shop for a LONG time with this one.
Transmission shifting rough at times, felt like it was slipping at others. There is now a TSB out for this, but since Chrysler was buying it back and the dealer was 25 miles away, we just dealt with it until turn-in.
Under warranty, Jeep replaced the transmission's valve body.
The transmission would only work in third gear. Under Jeep warranty, a Jeep dealer replaced the original transmission, which had been repaired in April, with a remanufactured transmission, but failed after 2,000 miles for the same problem.
Flashed TCM and updated software
Transmission was shifting hard when going from 8 to 7 and 6 gears. Dealer reflashed TCM, performed quicklearn. Issue seems to have gone.
delayed down shifts and up shifts intermitantly
have had thump on start up which they didn't find however they did several flash "Upgrades", now the doors don't unlock properly and the alarm goes off if I unlatch at the tail gate.
CEL lit up on a cold dark night. Went to the dealer the next day. They said the transmission valve body needed to be replaced. Got car back 4 days later. Shifts much smoother. But transmission drain pan is leaking so I have to go back.
