My '05 ltd. has apprx. trouble free 65,000 on it. My biggest problems have been:

The seat heater on the drivers' side quit working.
The cupholder - had to remove the spring to keep it from popping up.
The headlights - UV attacks them, fogging them up so they need constant attention - (like a lot of women I know)
The ashtray - won't stay closed.

Every problem listed with the possible exception of the ashtray, have solutions detailed out on this forum. Do some searching and enjoy!
