1999 PORSCHE BOXSTER User Comment / Complaint

I have had a reoccuring airbag light coming on, the dealer has had it on 5 occasions, and the previous owner had it to two different dealers ons 4 occasions. i thought that the dealer had it repaired in january of 2003, then it came back on again in jan of 2004. the dealer states that the repair is the seat belt buckles. they have replaced them 3 times, i dont know what the prevoius repairs were prior to my owning the vehicle. this time when i took the vehicle in for repair, it was no longer under warranty, and i was given a goodwill by the manufacturer for 50% of the repair bill. what is going to happen in a year when this comes on again? what would happen if i had an accident when the light was on because of this? the thing that stikes me the most is that the dealer has had the parts in stock every time and they have stated that this is a common problem, should there nt be a safety recall if this is the case?
