Chevrolet Suburban Recalls

The Chevrolet Suburban has 34 recalls spanning 2007 through 2024, with the most serious recent issue being a defect in the 6.2L V8 engine on 2021–2024 models where connecting rod or crankshaft components can fail internally, causing sudden engine shutdown while driving.

On 2023 models, rear suspension control arm bolts can fracture, causing rear wheel misalignment. The 2022 model year has two separate transmission-related issues on vehicles with the 10-speed electronic transmission: the transmission control valve can fail and lock up the rear wheels without warning. That same rear wheel lockup risk from a transmission control valve failure also affects 2021 diesel-equipped models. On 2021 models, a software fault in the electric power steering system can cause assist to drop out at startup or while driving, requiring noticeably more effort to steer. Also on 2021 models, the fuel pump control module can cause the pump to fail or run intermittently, stalling the engine unexpectedly. The 2021 driveshaft recall covers a separate issue where the rear driveshaft can fail and cut drive power without warning.

The 2021 model year also carries a cluster of occupant restraint issues: front seat attachment bolts may have been left loose or missing after an assembly repair, third-row outboard seat belts may have been routed incorrectly and damaged, seat belt mounting brackets in the front center position may not be secured to the seat frame, and incorrect bolts may have been used to anchor seat belt assemblies to the body. Third-row seat belt buckle rivets on 2021–2022 models may be deformed and unable to hold the buckle under crash loads. On 2021 models, the airbag warning light can fail to illuminate reliably when there is an actual fault in the airbag system. Daytime running lights on 2021–2023 models can stay on when the headlights are active, creating glare for oncoming drivers.

Going back to 2015–2020 production, a transfer case defect on four-wheel-drive and all-wheel-drive models can cause front or rear wheel lockup. On 2015–2020 models equipped with a 5.3L engine, a 3.08 rear axle ratio, and four-wheel drive, a faulty wheel speed sensor can trigger unintended braking on one side, pulling the vehicle sharply in that direction. The vacuum brake booster pump on 2015–2018 models can lose output over time, reducing brake assist and extending stopping distances. The 2020 model year has a fuel pump that can over-pressurize and crack, leaking fuel with fire risk nearby. Electric power steering on 2015 models can drop out suddenly or cut out and snap back, making the vehicle difficult to control at low speeds. Front airbag inflators and seat belt pretensioners on 2015–2017 models may fail to deploy in a crash. Rear seat belt retractors on 2018–2019 models may not lock when fully extended, preventing child safety seats from being properly secured.

The 2011–2015 model years have two ignition-related recalls: on 2011–2012 models, the ignition lock actuator can bind and then snap from the Start position back to Accessory, cutting engine, steering, and braking power. A narrower version of the same ignition snap-back issue affects certain 2015 models built during a short window in early 2014. The front passenger airbag
