2005 sport V6 For anyone that still has the seat problem and not had it fixed I just had mine done. After suffering for over 20k miles and complaining to Toyota and not getting anywhere its done And thanks to this great forum I picked up the TSB on the seat and armed with it went to the stealer and they acknowleged it and said they would order the new seat rails and call me. I was doubtful that just seat rails would fix this problem...it boings and bongs and all kinds of noise comes from it but it seams to have done the trick so far. Its been a week and no noise. What a relief...but you got to go to them with TSB ...don't no the no. but its here in the forum. Thanks to all who posted and pestered the stealers and Toyota...worked for me.
