My GMC Sierra has the RRAB recall. Vin has already been provided. I asked GMC in a chat (all recorded) if the truck is safe to drive. I explained that I am a disabled veteran. I have numerous issues but one has to do with not having full use of my right hand. I drive with my left and support with my right. I asked them if they though I could safely drive the vehicle knowing that information and they refused to answer uttering that parts are not available and be reassured that when they become available they will call. That truck is my only source of transportation. I need that vehicle to get me to chemotherapy sessions, yes I have cancer too!!! I need to know if the vehicle is safe to drive and if not, what is GMC going to do to fix this issue. I'm sure parts must be available but I doubt that disabled veterans or Joe public are not he priority list. I just want it fixed. …

My son's 2015 GMC Sierra side impact air bags went off while he was driving. He had no impact. He thought he hit a small pot hole but after driving back on the road, it was recently paved so it was not a pot hole. He guessed it was the edge of the road from the recent paving that he hit. He heard a loud noise like a gun shot. His cabin filled up with smoke and the side impact air bags when off. When he took the truck to the GM Dealership, it gave a code for front air bag deployment due to impact. But the side air bags went off and there was no impact. The only damage to the truck is the deployed side airbags and the locked seatbelts. He has a warranty but they kicked it to GM. Warranty stated that if they fixed it, they were worried that it would happen again. We filed a claim with GM. After GM sent three different inspectors out and over 5 weeks later, they denied the claim. …

Attempts to get the part replaced have been met with long delays in gets the parts necessary even though the dealer tells me they show plenty in their warehouse in another state. I first called on 3/29/23 and was told 1-8 weeks. I called again on 6/21/23 and was told they submitted the order again on 5/11/23 and would do so again today. I tried a second dealer in St. Louis and was told the same thing about expecting months of delays on these parts. This recall is from 2022 and if parts are available, why am I not able to get the repairs completed?

NHTSA investigations
Desiccated Air Bag Inflator Rupture
From 2000 through 2017, Takata produced millions of air bag inflators using two types of phase-stabilized ammonium nitrate ("PSAN") propellant -- propellant 2004 and propellant 2004L. After prolonged exposure to high temperature cycles and humidity, inflators using propellant 2004 can degrade, causing the propellant to burn too quickly when ignited.
