GMC Sierra 3500 Recalls

The GMC Sierra 3500 has 39 recalls spanning 2007 through 2026, with the most serious recent issue being a 2024 model year steering gear shaft that can fracture and disconnect from the steering arm, causing a total loss of steering control.

On the fuel system side, 2025-2026 models with gasoline engines and dual fuel tanks can experience a rear fuel pump that fails to transfer fuel to the front tank, stalling the engine while driving. The 2026 model year also has a compliance recall for a missing owner's manual in the vehicle's digital system. On 2020-2024 models equipped with power-unlatching tailgates, water intrusion can short-circuit the electronic release switch and cause the tailgate to open on its own, dropping cargo onto the road.

The 2021-2022 model years have a brake pressure modulator valve that may not be properly sealed, allowing water inside and raising the risk of an electrical fire. On 2020-2022 diesel-equipped models, the transmission control valve can fail and lock up the rear wheels without warning. The 2020 model year has several additional concerns: the front tank on dual-tank trucks can overfill and expand into the driveshaft, the hood latch striker wires can fracture and let the hood fly open while driving, seatbelt pretensioners can vent hot gas onto the carpet and start a fire inside the cabin, and a roof-rail airbag diffuser can separate during deployment and reduce curtain airbag protection. Seat belt anchor bolts on 2020-2021 models may be incorrect or unsecured at the front center position, leaving that occupant without proper restraint in a crash.

The 2019 model year has roof-rail airbag inflators on Crew Cab trucks where the end cap or inflator sidewall can rupture and send fragments into the cabin. The 2018-2019 model years share that same roof-rail inflator defect. On 2017-2019 models equipped with the Duramax 6.6-liter diesel and an optional block heater cord, an electrical short in the heater cable can start an engine fire. Those same years with dual fuel tanks can also experience a collapsing rear tank that stalls the engine. Seat belt retractors on 2017-2018 models were built with the wrong torsion bar and may not perform correctly in a crash. The 2015-2017 model years have a separate issue where front airbags and seatbelt pretensioners may fail to deploy in a crash due to a wiring fault. On 2015-2016 models, the brake pedal pivot nut can loosen until the pedal becomes inoperative and can catch on the accelerator, and roof-rail airbag inflators carry the same end-cap separation risk described above.

Going further back, the 2011-2015 dual-tank models have a sticking fuel level sensor that can cause the front tank to overfill and contact the driveshaft. The 2009-2014 model years have a passenger frontal airbag inflator that can explode and send metal fragments into the cabin, a defect tied to the broader Takata recall campaign affecting vehicles sold or registered in high-humidity states and territories. That same inflator explosion risk extends through the 2012 and 2013 model years under separate filings. The 2009-2014 models also have a fire extinguisher that may fail to function in an emergency. The 2007-2011
