I'm having the same issue (have been since 12k miles). The dealer has not been able to figure it out. Is there an easy way to check the strut top hat w/out complete disassembly? Cars still MDer warranty & they have an open PUMA case for it, so I'm not too concerned, but I'd like to get it remedied sooner than later, especially since I have the itch to start modding the suspension bits.
