I have a TSB summary list somewhere from last year, but TSB does not guarantee any response unless the problem is verifiably reproduced at the dealer. Dealers reputedly don't like owners showing up waiving TSBs around requesting phantom fixes by neurotic or demanding owners, or so I'm told.

CPO is now fairly valueless -- the new owners downgraded the program recently to only 1 year, so check more.
