Car Will Not Start problems of the 2006 Nissan Titan

Air bag warning light started blinking. Diagnostic gave code of crash zone sensor communication error. Researched issue on line and see that there is a recall for snow belt states which maine is included but not the Titan. Contacted Nissan regarding issue and was told that they would not cover because we are outside of warrantee? find it odd that some vehicles are being covered but not this one. Previously to the airbag light issue my husband was driving on the interstate doing approximately 70 mph when the vehicle abruptly lost all power. Thankfully no vehicle behind him. He pulled over into breakdown lane tried to restart vehicle wouldn't start initially but after 10 minutes did start. No codes to be read not sure if this is related to the airbag issue but obviously not safe to have your vehicle abruptly shut down at 70 mph.

My vehicle impacted another vehicle from the rear and air bags did not deploy. The air bag light has been on. Several electrical problems; steering wheel buttons stopped working in 2008, abs light remains on, backup sensor went out 11-17 and most recently I started my vehicle one morning and speakers started popping really loud and immediately smelled of burned wires and just two days later vehicle would not start, battery was completely drained. After charging worked fine for a couple of days but just repeated the same situation. This vehicle has gave me so many electrical problems starting a year after purchase. Also noticed that one of the a frames welded joints is cracked. I am a certified welding inspector and can say that it is a manufacturer discontinuity. The catalytic converters went out years after purchase in 2006. I have had to replace the engine because of the catalytic converters. I am the one and only owner and purchased it new with only 17 miles on it. This vehicle has had so many electrical/mechanical issues that im starting to think I should apply under lemon law but I dont know how to do that.
