I will make sure to look into these two when I am looking at vehicles.
To elaborate: replacing fuel tank involves disassembling drivetrain and I don't want this, so I just live with it. It is not noticeable on the highway, only in stop-and-go traffic.
I heard mosquito noise from AC a couple times. Will test it again soon and will probably get it fixed wile it is still on factory warranty.
Other problems experienced by some people that aren't specific to '11 and haven't been fixed:
1) Problems with QL suspension (nitrogen leaks, difficult to diagnose/repair)
2) Leaks/rattles from pano moonroof
3) Shudder with HEMI engine.
I don't have any of these options of my Laredo X, so can't personally comment.
IMPORTANT: as someone else mentioned above there were reported problems with V6 engine that required engine head replacement. Chrysler never officially announced what vehicles are affected and what exactly the problem is.
Note that if your car is under 36,000 miles and under 36 months old you can still buy Chrysler extended warranty for it (but double-check mileage/age numbers, this is what they used to be a while ago, may be they were changed).
