“This is not connected with a specific crash in this vehicle. It is a defect with all vehicles with this seat. There is known common defect with the stitching on the side of the front seats covering the airbag. The stitching is designed to come apart if an airbag is deployed. The defective stitching deteriorates and falls apart. This exposes the airbag system in the seat. This occurs on all GM vehicles with the same leather seats. Models include Suburbans, Yukons, and pickup trucks. In this Suburban the stiching started to come apart about 6 years ago with a few loose threads. The entire side of the seat has now come apart. The rest of the seat is in relatively good repair without any holes, rips or torn stitching. GM claims this is cosmetic and not covered. The safety issues caused by this includes the potential deterioration of the airbag system interfering with deployment in a crash. Another safety issue is the potential for foreign objects to get lodged in this space and injuring someone if the airbag goes off. The third safety issue is the potential of a person, or child, to access the airbag and cause it to go off without warning.”
