Typical seat belt symptoms owners report

  • Owners report the seat belt tensioner cable or cover detaching or loosening, most often on the back center seat, sometimes recurring after a dealer repair.
  • Some drivers say the tensioner-related recall repair (campaign 16V209000) was delayed because replacement parts were unavailable.
  • Several complaints describe the seat belt anchor point fracturing or the lower buckle assembly snapping apart at the floorboard, making the belt inoperable.
  • Other owners note the visible cosmetic damage left by the recall fix on used vehicles, which they say discouraged some from completing the repair.
  • A few complaints mention the seat belt warning chime failing to sound, tied to a separate electrical system issue some owners linked to an earlier recall that GM said did not apply to their VIN.

Seat Belts recalls for the 2015 GMC Sierra 1500

  1. NHTSA 21V245000Apr 8, 2021Seat Belts2,568 vehicles

    Seat belts:front

    General Motors, LLC (GM) is recalling certain 2014-2016 Chevrolet Silverado 1500, 2015-2016 Chevrolet Tahoe, and 2014-2015 GMC Sierra 1500 vehicles that may have received an incorrect replacement tensioner cable assembly as part of a previous recall remedy or a subsequent repair. The flexible steel cable connecting the driver's seat belt to the outboard side of the seat may be repeatedly bent over the seat side shield as the driver enters and exits the vehicle causing the cable to fatigue and separate.

    Risk: A broken pretensioner cable reduces the effectiveness of the driver's seat belt, increasing the risk of injury.

    Remedy: GM will notify owners, and dealers will replace the driver seat belt lap pretensioner, free of charge. The recall began on May 5, 2021. Owners may contact Chevrolet customer service at 1-800-222-1020, and GMC customer service at 1-800-462-8782. GM's number for this recall is N212330040.

    Seat belts:pretensioner

    General Motors LLC (GM) is recalling certain model year 2014-2016 Buick Lacrosse and Chevrolet Spark EV, Caprice PPV and SS vehicles, 2014-2017 Buick Encore and Chevrolet Corvette, Silverado 1500 and GMC Sierra 1500 vehicles, 2015-2016 Cadillac Escalade and Escalade ESV, Chevrolet Tahoe, Trax, Suburban and Silverado 2500 and 3500 and GMC Yukon and Yukon XL vehicles, and 2015-2017 GMC Sierra HD 2500 and 3500 vehicles. While being previously remedied for recall 16V-651, the affected vehicles may not have received the complete software update necessary to remedy the recall condition. Without the update, certain driving conditions may cause the air bag sensing and diagnostic module (SDM) software to activate a diagnostic test. During this test, deployment of the frontal air bags and the seat belt pretensioners would not occur in the event of a crash.

    Risk: A failure of the front air bags or seat belt pretensioners to deploy in the event of a crash necessitating deployment increases the risk of injury to the driver and front passenger.

    Remedy: GM will notify owners, and dealers will reflash the SDM software. Vehicles that have had a previous air bag deployment will have the SDM replaced. These repairs will be performed free of charge. The recall began on August 4, 2017. Owners may contact Buick customer service at 1-800-521-7300, Cadillac customer service at 1-800-458-8006, Chevrolet customer service at 1-800-222-1020, or GMC customer service at 1-800-462-8782. GM's number for this recall is 17287.

    Seat belts

    General Motors LLC (GM) is recalling certain model year 2014-2015 Chevrolet Silverado 1500 and GMC Sierra 1500 trucks manufactured January 29, 2013, to January 21, 2015. While entering the vehicle, the seat belt tensioner cable may be positioned such that the driver slides over it. This movement may result in the fatigue and separation of the cable.

    Risk: If the tensioner cable separates, the driver may not be properly restrained in the event of a crash, increasing their risk of injury.

    Remedy: GM will notify owners, and dealers will modify the vehicles to prevent the tensioner from being damaged. Any tensioner that has already been damaged will be replaced, free of charge. The recall began on August 11, 2016. Owners may contact Chevrolet customer service at 1-800-222-1020 or GMC customer service at 1-800-462-8782. GM's number for this recall is 15822.
