Air Bag Not Deploy problems of the 2008 Nissan Maxima

Air bag warning light came on. I took same to Nissan dealership service center and had a diagnostic test done on it which cost me $98. 00 and the advised me that the air bag spring is weak, air bag has never been deploy and then the tell me if in an accident it may/may not deploy. (also if hit a hard enough bump it may cause it to) this has to be a defect why would a steering wheel air bag spring just go weak and there is not wear and tear to it. This sounds like a defect to me. I have known a guy that had to replace his. So I am probably not the only one with this problem going on. When this happen I checked for recalls by it stated none had been reported.

The contact owns a 2008 Nissan Maxima. The contact was sitting idle at a traffic stop when a vehicle crashed into the rear of his vehicle at approximately 35 mph, which caused the vehicle to front end an eighteen wheel truck. The contacts airbags did not deploy. The contact sustained neck and muscle injuries. A passenger sustained injuries to the lower back. The vehicle was destroyed. A police report was filed. The current and failure mileage was approximately 38,000.
