If your Honda driver-side airbag is defective and the repair is delayed (parts not available or scheduling), then your Honda dealer is supposed to either give you a loaner or pay for a rental for you (from Enterprise) until your car can be repaired. The rental may not be offered up front to you so be aware that you may need to request it.
If it is only the front passenger-side airbag then you’ll likely be told to just not have anyone sit there, though you can request a review for a rental if you regularly have several people in the car.

Should there be any wait for the replacement of driver’s airbag inflator, our dealers are prepared to provide alternative transportation in the form of a loaner or rental vehicle, free of charge, until your own vehicle is repaired. Honda will directly review loaner vehicle requests from Honda and Acura owners of vehicles requiring only replacement of the passenger front airbag inflator through its Automobile Customer Service office at (888) 234-2138.
