Air Bag Not Deploy problems of the 2010 Nissan Titan

I recently had air bag light start flashing. I took in to Nissan dealer to get checked and they said the "spiral cable" was bad, this is also known as clock spring. Nissan reset and said bring back if occurs again. It did and I took to another shop for second opinion and same result. I agreed to get part to fix the truck. After being told part was on back order no eta on delivery of parts from Nissan. After 4 weeks I checked and found out the same dealer has 6 other "spiral cables" on back order. As I stand now, according to Nissan my trucks driver side air bag will not deploy if needed, and no eta on parts.

The contact owns a 2010 Nissan Titan. The contact was driving 30 mph when the vehicle crashed into another vehicle’s rear end and the air bags failed to deploy. The crash caused two individuals to suffer injuries to the neck, back, arm and chest. The police were notified and a police report was on file. The vehicle was towed to a private repair shop. The manufacturer was notified. The vehicle was not repaired. The failure and current mileages were 22,000. The VIN was unknown.
