Service airbag light and warning indicator came on when car is started. Took to GM certified dealership for service. Was advised code B0058- right front pretensioner defective on passenger seat belt buckle. The dealership advised that this part is no longer available from GM and therefore they wouldn't be able to make repairs. Also advised that the air bags are disabled and will not deploy. Was told to contact GM customer service. After 3 weeks of lengthy telephone conversations, still no help from GM. Searched every online website and this part is not available. Please advise what if anything can be done to stress the importance of this issue with GM.

The driver's seatbelt twisted on this '04 caddy Cts with 70K miles. The local repair shop told us to take it to the dealer. The dealer wanted hrs of labor guestimated at $170 to take it apart. Isn't it essential that a safety feature holds up. The car is mostly driven by a light weight woman who is very careful. I thought the manufacturer should warranty the seatbelt design longer! this is the first time this is happened in the 20 cars we have owned since seatbelts were standard. Are there any other such complaints?> these front belts come from the top of the seat.

Consumer has concern with the safety belt. The safety belt does not utilize a ratcheting style safety belt harness. The consumer had a professional install his child's safety seat but the belt would only hold temporarily. Any wiggling of the seat caused inches of slack.
