Just picked up my 2014 GC after it being in the shop for 2 days. Complaints were: Collision Avoidance not working, iPhone will not stay connected longer than 20 minutes, rattle in right rear door when closing, rear hatch handle loose, chrome around left taillight loose, loud clunk when shifting back into drive after towing in neutral, both mirror warning lights illuminated at the same time for approximately 15 minutes without any vehicles being in close proximity.
Collision Avoidance still not working, iPhone not even recognized now, rattle still in the door, latch still loose, chrome around left taillight tightened.
The following updates/solutions were performed that were supposed to fix the problems:
N55 recall to fix Collision Avoidance issue. Doesnt seem to have worked.
RRT 13-071 for the iPhone connection. Did not work.
Dealer did not want to start work on door rattle due to up coming holiday (Thanksgiving) as it would take quite some time to complete. Had to order a new rear hatch handle. Waiting on parts for that.
Was told that the "clunk" sound was normal when shifting back into gear from neutral.
No codes or updates were found in the blind spot mirror system.
So far, not very impressed with "the fix".
