What can fail
The front passenger air bag inflator may explode due to propellant breakdown after prolonged exposure to high humidity, high heat, and temperature changes.
This page covers 4 recalls, 64 owner complaints and NHTSA crash-test ratings for the 2012 GMC Yukon.
4/5 Overall
NHTSA 5-Star Safety Rating
For the 2012 GMC Yukon, the dominant complaint pattern centers on structural issues, particularly dashboard cracking. Owners frequently describe the dashboard developing cracks that spread across the surface over time, often originating near the airbag cover or instrument cluster area. Several owners specifically note concern that a cracking or separating dashboard could send plastic fragments toward occupants if the airbag deploys. Airbag complaints are the second most-reported named system, with the dashboard cracking pattern tying directly into those concerns. A smaller cluster of complaints involves engine behavior, with owners describing sudden loss of power, misfires, and loud tapping or banging noises sometimes accompanied by warning lights for engine, traction, and braking systems appearing simultaneously. The dashboard cracking issue appears to be the most consistent thread across this complaint set, with multiple owners describing cracks that started small and progressively widened or separated across a significant portion of the dash surface.

By System
The 2012 GMC Yukon has 4 recalls, all involving the front passenger airbag inflator, which can explode with excessive force and send metal fragments into the cabin, with the potential for serious injury or death.
All four recalls address the same fundamental hazard: the passenger-side front airbag inflator can rupture during deployment. Over time, prolonged exposure to heat and humidity degrades the propellant inside the inflator. When the airbag fires in a crash, the inflator can burst apart rather than inflate the bag normally, scattering sharp metal pieces toward anyone in the front passenger seat or nearby. These recalls apply specifically to vehicles originally sold or registered in high-heat, high-humidity regions, including states like Florida, Texas, Hawaii, and Louisiana, as well as U.S. territories such as Puerto Rico and Guam, where the environmental conditions that accelerate propellant breakdown are most pronounced. Multiple recall campaigns cover this defect across overlapping model years and vehicle lines, but the physical risk in every case is the same: a compromised inflator that turns a crash into a secondary fragmentation hazard.

What can fail
Heat and humidity exposure can degrade the propellant in the passenger-front airbag over time, potentially causing it to deploy with excessive force or rupture, sending fragments toward occupants or damaging the airbag assembly.
What the fix does
The dealer will replace the passenger-front airbag inflator as a precaution before any malfunction occurs.
