Summary
The GMC Sierra 1500 has 8 recalls across the 2014-2022 model years, with the most serious being a brake caliper bolt defect on 2020 models where the bolts can break under load, reducing braking performance or locking up wheel rotation.
On 2020 models, the roof-rail curtain airbag inflator can have a diffuser that was not properly crimped, causing it to separate during deployment and reduce the airbag's ability to protect occupants in a crash. Also on 2020 models, a 2019-2020 electrical issue carries over: the battery positive cable can have excess adhesive that causes an intermittent connection to the alternator, allowing the engine to stall unexpectedly while driving. The 2019 model year has two additional concerns. Certain tires fitted at the factory were over-cured during production, which can cause a sidewall crack or tread separation at highway speeds. There is also a software error in the electronic brake control module that can disable the electronic brake assist function, leaving the driver with reduced stopping capability. On 2014-2017 models, the front airbag and seatbelt pretensioner system has a wiring issue that can prevent both from deploying in a crash, leaving the driver and front passenger without full restraint protection. The 2022 model year has two lower-severity issues: vehicles equipped with an accessory sport bar may have a non-functional high-mounted brake light that also blocks the factory brake light, making the vehicle harder for following drivers to see when stopping, and trucks fitted with chrome front grille deflectors can lose the clips holding the deflectors in place, sending the piece into traffic.
