2021 GMC Yukon: airbag warning light

Filed Jun 16, 2026 · Airbags · NH

1. Component / System Failed: The Supplemental Restraint System (SRS) / Driver’s Inboard Seat Airbag circuit has chronically failed, leaving the vehicle's primary safety restraint systems disabled. The faulty components and the physical service records documenting the failure are fully available for inspection upon request. 2. Safety Risk: The driver's safety and the safety of passengers are put at extreme, immediate risk. Whenever this failure occurs, the "Service Safety Restraint System" warning illuminates, which completely disables the airbag deployment system. Driving a heavy passenger vehicle (2021 GMC Yukon) without active driver-side airbag protection leaves the operator exposed to severe injury or fatality in the event of a collision. 3. Dealer Confirmation / Reproduction: The problem has been reproduced, diagnosed, and confirmed by an authorized dealership (Quirk GMC in Manchester, NH) on five separate occasions spanning from August 2025 to June 2026. 4. Inspections: The component has been repeatedly inspected by the manufacturer’s authorized dealer technicians at Quirk GMC. It has not yet been inspected by police or insurance representatives, as no crash has occurred. 5. Warning Lamps / Symptoms: The failure is preceded by the "Service Safety Restraint System" dashboard warning lamp and message illuminating. This symptom first appeared in August 2025 at 78,472 miles and has continuously reappeared shortly after every subsequent repair attempt made by the dealership, indicating a continuous, unresolved defect in the vehicle's safety manufacturing or a severe failure in the manufacturer's diagnostic repair procedures.

There are apparently a couple of faults affecting the SRS and leading to a periodic airbag light and "Service SRS" warning. GM has issued/revised a few Service Bulletins related to this warning. Some are related to software, some are related to overhead wiring, some are related to the clock spring in the steering wheel, and some are related to the driver's side airbag module. My understanding is that when the SRS warning appears, all airbags are disabled and GM says we drive our vehicles at our own risk. To my knowledge this has affected several models of approximately 2021-2023 GMC (Yukon and Sierra) and Chevrolet (Tahoe, Suburban, Silverado) SUVs and trucks.

I received the car on 9/8/2020, I started noticed a error message on 19sep2020, that stated service safety restraint system with the airbag warning light coming on. This light comes on and off so there is no way to tell for sure if the airbag is working appropriately. The message comes on both if you are in motion or stationary.
