Air Bag Not Deploy problems of the 2014 Chevrolet Suburban

Would get intermittent air bag warning light. Took it to one dealership and found no codes. Later I figured out it would only be on with a passenger in the seat and took it to another dealership where it was found to be the passenger presence module. With the light on the airbag will not deploy. Filed the complaint with gm warranty department as the truck is a 2014 model and only 54,000 miles, gm will not warranty or pay for the fix. Had to pay out of pocket to correct this safety feature.
