Mar 2010 15000 mi	Trunk side panel would not stay latched closed, upon delivery when new. Dealer ordered part and I waited until the 15k service to have it replaced.

Adjusted shift linkage which was out of spec - improved but not good enough yet. HVAC smells like mold or mildew when the AC button is active. Dealer replaced filter as part of 15k service and hoped this would fix. Offered to deodorize the system but not under warranty.
