Air Bag Light On problems of the 2005 GMC Canyon

I got a safety bulletin from GMC #14609 stating that there is a problem with my air bag light,. It can go on due to wires in the rear door breaking, the air bag can go off also. This is a safety issue with the air bags, I have the problem with the air bag light on. They said they would fix it or reimburse me if I paid in the past to have it fixed. Well they said I was off of warranty 1-15 . This is a safety issue, the dealer will not fix it for free. Why did they send me this bulletin with my VIN number attached? I have had nothing but problems with this GMC truck, you name it it has had a problem. Mostly electrical system failure. The air bag issue should be fixed by GMC free of charge which they state in the letter, there telling me I am a few months past the 10 year dead line. That is a disgrace this is a safety issue and should be covered by GMC if it is a design problem like all the other problems I am having. They are getting away with this and the air bag can go off while driving and cause an accident. I am holding them liable for this problem. What can I do about this they are not helping me with this safety issue. Thanks, tom.

After getting my truck washed the airbag light came on and would not go out. I took the vehicle to GMC today, may 8, 2012, and they found a wire under the carpet in the rear passenger area broken. This vehicle has never been in an accident and very seldom has passengers in the rear seat area.

The contact owns a 2005 GMC Canyon. The contact stated that the air bag light would illuminate upon starting the vehicle. The vehicle was not taken to have the failure diagnosed or repaired. The manufacturer was not made aware of the failure. The failure mileage was 55,500.
