Front Air Bag Sensor Control problems of the 2013 Dodge Dart

I am having problems with body control module and this damaging all my vehicles sensors as the sensors are damaged the actual system which is the engine and the mechanical system is damaged and car won't start it stopped in the middle of the road and then after few trials I some how started it and then it stalls but this stalling is really dangerous because the bcm is sending wrong signals to the accelerator and it accelerates even I have eased the gas so if anything happens later or now I would blame Dodge for making such a worst car and also the NHTSA for giving Dodge the permission.

The sensor light came on while I was driving with my father in the passenger side , and indicating that the seat belt is not buckled but it was , and the warning on the dash says air bag service deployed but the nothing came out , but I never hit anything , also the noise for the seat belt keeps going off as if the seat belt is not buckled when it is , I never had problem before with car its creepy and scared for my wife and father who sit iin the seat , please help me.
