I know a few of you have posted about your driver's side seat squeaking, How about your Passenger's side?

Ever since I went down to the Tail of the Dragon meet in NC in my car, I've been hearing it from time to time.

I took it to the dealership today (Lexus of Bridgewater) and I thought it was Driver's seat and they couldn't duplicate the problem, greased up the tracks and released my car.

I thought everything was good and dandy until I picked up my cousin for some lunch and the very first turn I made, SQUEAK!

I'll be returning to the dealer as soon as possible and update but back to my question, Have any of you had your passenger seat squeak?
