Air Bag On-off Switch problems of the 2008 GMC Yukon

I bought this SUV from legends auto sale. After I bought it, I notice the engine bay was real rusty like its been in water or driven over lots of water. I didnt get a car fax at time of purchases but did car fax myself , and it appeared that vehicle is from new orleans. With all the dirt and grim coming out of vehicle its diffently from new orleans. So far I replaced new pads and rotors, master cylinder, brake switch, new spark plugs and wires. The problem occurring now is that my trac light and abs light will come on after half hour of driving and car seizes up and I'm unable to accelerate. I would have to shut off engine and let rest for half hour to an hour before lights goes away and I'm able to move again. I'm not sure but it might be due to it being in the flood thus causing corrosion and rusting in all parts of vehicle. I don't have documents on me at this time as I misplaced it but can get it again and upload image.

I've received letters from the GMC dealership that my vehicle needs a recall with a dangerous takata airbag, but there is no part available yet. It has been over 2 years since I was first notified of this issue. I live in a hot and humid area (hawaii), which is supposedly worse for the issue with the airbag. I am concerned for the safety of my family which driving this vehicle. The vehicle is almost 11 years old, I feel the auto maker is trying to buy time until the engine goes out possibly. I plan on keeping this vehicle for another 10 years at least, replacing the engine if need be. I would like some help getting this issue resolved, and in the meantime will try to get approved for an on/off switch for the affected airbag. It also seems strange that only one side would be affected, as the explosive propellant causing the issue would no doubtedly be on both sides.
