general problems of the 2004 Hyundai Elantra

I have contacted customer care and was told it's standard to remove a front seat and give the car back until they get parts for the recall I feel this could cause air bag systems not to be active and also without the seat the cars ability to hold up in a crash is reduced due to missing components that provide some structural support all I have requested was a rental car for the time it takes to perform my recall as I do not feel safe driving a car without a front seat I have had the dealer decline my request and said if I want it done the seat will be removed and the car given back to me is this a safe practice for a dealer to remove a seat that has one of the side air bags in it and advise the owner to drive the car as normal? any assistance with this company will be much appreciated and to be clear there is a active air bag light on with a code the relates to occupancy detection for passanger front and side air bags.
