GMC Sierra Recalls

The GMC Sierra has 121 recalls spanning 1990 through the 2026 model year; the most serious recent issue affects 2024 Sierra EV trucks, where insufficiently insulated wires in the rear electric drive unit can contact each other and cause a sudden loss of drive power while moving.

The 2024-2025 Sierra EV also has a recall where the bolt securing the rear center seat belt to the seat structure may not be properly tightened, which can allow the belt to detach in a crash. On 2024 Sierra EV models, the front turn signals and parking lights can be too similar in brightness, making the turn signals hard for other drivers to see. The 2026 Sierra EV has a software issue where, after an electronic stability control malfunction, the ESC warning light may not illuminate on the next key cycle, leaving the driver unaware the system is inactive.

The 2022 model year has two lower-severity issues: an accessory sport bar whose high-mounted brake light may not activate and also blocks the truck's existing lamp, and a chrome front grille deflector that can detach while driving. The 2023 model has a power-locking tailgate that can unlatch while parked if water enters the exterior switch, dropping the gate and potentially spilling unsecured cargo onto the road.

The 2019-2020 generation carries a cluster of recalls. On 2020 models, brake caliper bolts can fracture under load, allowing a caliper to detach and severely reduce braking. On 2019 trucks, the positive battery cable nut at the alternator can loosen, causing an engine stall or electrical arcing that may ignite surrounding materials; a driveshaft weld can fail and cut power to the wheels; and ABS and electronic stability control can silently disable due to a software error. Several 2019 recalls also address tri-fold tonneau covers that can detach at highway speed and become road hazards, with prior repair attempts on some of these requiring a second fix. A spare tire size mismatch on certain 2019 models with 18-, 20-, or 22-inch wheels can cause ABS to behave incorrectly when the spare is on a rear position. On 2019 models, Continental tires with specific date codes can develop cracked sidewalls or tread separation, leading to sudden pressure loss.

The 2014-2018 era has the densest recall concentration. On 2018 trucks, defective side curtain airbag inflators can deploy without a crash and propel parts toward occupants. The 2015 model year has rear axle shafts that can fracture and separate a rear wheel, diesel fuel line fittings that can leak near ignition sources, a vent line hose clamp that can allow fuel to leak, power steering hose clamps that can let fluid escape, exhaust overheating that can melt nearby plastic components and start a fire, and side curtain airbag inflators that can fail and send metal fragments into the cabin. A 2015 power steering recall covers a sudden loss of electric assist. The 2014 model year has an ignition lock that can snap from "Start" back to "Accessory" and kill engine, steering, and brake power; a transfer case that can silently drop into neutral; a tie rod that can loosen and separate from the steering rack; overheating wiring near a power sliding rear window that can cause smoke or fire; a brake vacuum pump that can weaken and require harder pedal force; and multiple airbag module issues where the sensing and diagnostic module can
