02 grand prix gt owners should be getting something from pontiac stating that the cat convertors can fail because something may fall off. They will replace if you have problems or will refund if you have had a new one installed. I personally had to change the c.c the egr valve, and i also changed both o2 sensors. piece of junk. close to 700 bucks for all that
if your c.c. works fine they won't do anything!! it says that it is not a recall notice on my statement i got from pontiac. The address is recall processing center po box 909989 milwaukee wi 53209-9989 and # you could call would be either 18006207668 or reimbursement questions 18002040261.
hope this helps
