Service bulletin 17367-01

A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it. The summary is NHTSA's. The document is the manufacturer's: read it at NHTSA. A bulletin is not a recall, and listing a model year does not mean every vehicle of it is concerned.

NHTSA's summary

The driver’s and front passenger’s seat belt retractors in certain 2017-2018 model year Chevrolet Silverado Heavy Duty (2500 and 3500 Series) and GMC Sierra Heavy Duty (2500 and 3500 Series) vehicles may have been built with different torsion bars than were used in testing the vehicles for the Government 5-Star Safety Ratings listed on the window sticker. While these vehicles comply with all applicable government safety standards, this condition may affect the Government 5-Star Safety Ratings listed on the window sticker. Correction Customers have the choice of whether to have this replacement performed. If the customer chooses to have it completed, dealers are to replace the driver and front passenger-side seat belt retractor assemblies with assemblies containing the correct torsion bar.
