GMC Sierra 1500 Recalls

The GMC Sierra 1500 has 48 recalls spanning 2007 through 2026, with the most serious recent issue being a defect on 2021–2024 models equipped with the 6.2L V8 engine where connecting rod or crankshaft components can fail internally, causing sudden engine failure and loss of propulsion while driving.

On the newest end of the production run, 2026 models with four-wheel or all-wheel drive have a transfer case defect that can lock the front or rear wheels unexpectedly. The 2023 model year has a brake control module software error that fails to illuminate a warning light when brake fluid is low, meaning the driver may not know stopping performance is degraded. On 2022–2023 models, the daytime running lights can stay on when the headlights are activated, creating glare for oncoming traffic. The 2022 model year also has a grille deflector attachment that can fracture and shed the deflector onto the road, and an accessory sport bar brake light that may not function while also blocking the factory high-mounted brake light.

The 2020–2022 model years with diesel engines have a transmission control valve that can fail and lock the rear wheels. An earlier repair attempt for this issue did not fully resolve it on some 2020–2022 vehicles. On 2019–2021 models, the front-row center seat belt bracket may not be secured to the seat frame, reducing restraint effectiveness in a crash, and certain accessory wheel and spare tire combinations can interfere with anti-lock brake function. The 2020 model year has several concentrated issues: brake caliper bolts that can break and reduce stopping power or jam wheel rotation, a fuel pump missing a pressure regulator that can crack under over-pressurization and leak fuel near ignition sources, and a driveshaft weld that can let the shaft separate while moving. On 2019–2020 models, a battery cable with excess adhesive can cause an intermittent connection to the alternator and stall the engine, and front seat belt pretensioners on carpet-equipped vehicles can vent hot gas that ignites the flooring. The 2019 model year alone has two brake-related software issues: one that can disable electronic brake assist, and another that can disable both anti-lock brakes and stability control simultaneously. There is also a 2019 Crew Cab recall where the passenger frontal airbag module may have been damaged during assembly and could fail to inflate properly in a crash.

The 2018 model year has a vacuum pump that can weaken over time on 5.3L and 6.2L V8 models, requiring noticeably more pedal effort to stop. Roof-rail airbag inflators on 2018 models can rupture or shed their end caps into the cabin. The 2015–2016 model years share a similar roof-rail airbag defect where the inflator end cap can detach and be propelled into the occupant space. On 2014–2018 models, the vacuum brake assist pump can gradually lose output, extending stopping distances. The 2014–2017 model years have two related recalls where front airbags or seat belt pretensioners may fail to deploy in a crash. On 2014–2015 models, the driver's seat belt tensioner cable can fatigue and separate if the driver slides over it while entering, and a separate recall covers vehicles that received an incorrect replacement tensioner cable during a prior repair. The 2014 model year has an electric power steering system that can momentarily drop assist and then
