General Motors will be asking the owners of certain Chevrolet and GMC trucks to return to their dealerships because of a problem affecting the front seat belt pretensioners.
According to the defect report filed with the NHTSA, during a crash that requires the seat belt pretensioners to deploy, the exhaust from the deployment may be diverted trough an opening in the pretensioner bracket which could ignite the cotton fibers in the carpet around it. (This opening was intended as a locator hole for assembly but was never used.) Following a crash that deploys the seat belt pretensioners, drivers may notice smoke or a burning odor from the area at the base of the B-pillar before a fire is visible.
The vehicles affected by this recall include:
Dealers will correct the problem by closing off the opening in the pretensioner bracket with a plug.
