GMC Air Bag Recalls Cover Inflator Ruptures and Deployment Problems
Roof-rail inflator failures recur most often in these GMC notices, particularly for the 2018 Sierra 1500 and 2019 Sierra 2500 and 3500. The October 2024 notice also includes 2018 Sierra 2500 and 3500 trucks. Those notices describe inflator end-cap detachment or sidewall rupture; the July 2020 notice instead describes diffuser separation on 2020 Acadia and Sierra models. Other problems include an inoperative crash-sensing module in the 2018 Terrain, an unactivated module in the 2022 Acadia, passenger classification errors in the 2023 Terrain, incorrect deployment software in 2024-2026 Canyon AT4X AEV vehicles, and inconsistent air bag warning-light illumination in 2021 Yukon and Yukon XL vehicles.
Warning signs to watch for
- June 10, 2021 Yukon/Yukon XL recall: The air bag malfunction indicator light may illuminate inconsistently and fail to warn of an air bag problem.
Can you keep driving? What the notices say
None of the listed GMC air bag notices instructs owners to stop driving or park outside. This includes the May and December 2018 notices, July 2020 notice, June and September 2021 notices, and December 2022 notice: they do not tell owners to stop driving. The October 2024, June 2025, December 2025, March 2026 and May 2026 notices likewise do not tell owners to stop driving. These statements report the driving instructions in the supplied notices.
What the free repair involves
Free remedies include SDM software updates for the 2018 Terrain and Canyon AT4X AEV, air bag module replacements for specified Sierra recalls, and passenger presence system replacement for the 2023 Terrain. Yukon/Yukon XL gateway software receives a free dealer or OTA update. The 2022 Acadia notice specifies assembly-plant SDM activation for vehicles still in dealer inventory, without stating a charge.
