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

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.
SERVICE SHIFTER message appeared. Vehicle ran rough and could not shift into park. Left me stranded on the side of the road late at night. Towed to dealer for valve body replacement -- the second time this part was replaced.
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.

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.
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.
Transmission jerking from acceleration and deceleration.
Transmission shifted rough, lagged, hesitated, slammed gears. TSB performed. 100% different vehicle after update. Corrected all issues.
