New JGC L owner Limited trim (as of 10/9) with 507 miles on it - like the vehicle with some exceptions so far. First day encountered rough shifts from first to second (shudder that can clearly be felt in the passenger cabin) Then noticeable downshifts from higher gears when coming to a stop. Noticed the rough shifting occurs when transmission temp is above 170 degrees F. Other issues have popped up including USB ports not charging consistently, Carplay glitches, noticeable wind noise coming into the sunroof, and a vibrating brake pedal after brake pedal is depressed for more than 6 seconds at a stop light. Front facing camera also got hit with a small rock on a highway and is cracked.
Dealer initially did a software update to try to address trans issues, which did not resolve issues. Dealer is now looking into transmission issues with Chrysler tech engaged after being able to replicate rough shifting. Initial diagnosis is a new transmission valve body is required to remedy the shifting issues, but no ETA on part as the part is backordered.
