Air Bag Light On problems of the 2012 Chevrolet Colorado

About 3 months ago, the airbag light come on, I've checked the codes it gives me and it b0065, b0066, I've checked all the wires and they are in perfect condition, don't know what to do now.

Shortly after I bought this truck with 33000 mile on it in June of 2018 the airbag light came on for no apparent reason and has continued to remain lit since that time. Since the vehicle is no longer under warrranty, I have been unable to get it repaired.

2012 chev Colorado extended cab (purchased new in 2012). Air bag light is on. 1st incident Aug 2015 (32,000 miles). Dealership ran diag scan and pulled code b0092 and repaired wires under passenger seat and cleared code. 2nd incident less than 4 months later (34,000 miles) ¿ dealership cleared code. 3rd incident Apr. 2016 (37,000 miles). Dealership found b0092 set in sdm. An inspection found three wires broken. Repaired wiring under passenger seat and cleared code. Nothing is being put under the seat. The seat occasionally gets moved forward and backward and the rear passenger door gets open and closed. An internet search reveals same problem in older models. This is definitely a safety issue. The air bag will not inflate if there is an accident. There is obviously a problem with the wires (poor quality or too short causing tension and wear & tear?). A recall should be issued and proper wiring and/or connections corrected. Also seems that the cost of repairs ($120 - $140 per incident) should be covered under warranty.
