The driverÂ’s and front passengerÂ’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.
