Front Air Bag Sensor Control problems of the 2007 Dodge Nitro

My airbag sensor will not stop chimming. It worries me because I'm uncertain if it will eject while just driving. That cause an accident oppose to being safe.

For 4 months since purchase of this vehicle 2007 Dodge Nitro it has been in the shop 8 times for issues such as; gas tank loose, stalling, lack of power, esp/bas lights malfunctioning, transmission mis-shifting, air bag malfunctioning. The dealer keep saying they are running updates but the problem still occurs. I am fearful of what could happen to me and my children while driving this vehicle and it malfunctions again.
