I got a recall letter in the mail about a week ago concerning this, yes if you had it replaced they should reimburse you for it, does anyone need info? Not a real recall but they say if you are affected by this they will repair it. I am the original owner (2005) so maybe I was easier to track down. Probably a bit more proactive in this with the ignition switch fiasco on the Cobalt, etc.
Waiting for all you Guinea Pigs to make GM get them sorted out before I buy.
