Two separate defects have led to the recall of half a million Audi vehicles in the United States.
Some A5 and Q5 SUV engines may have an electric coolant pump that could get blocked with debris.

If that happens, Audi says the pump can overheat and cause a fire.
In a separate issue identified by Audi, the sunroof drainage system in the Q5 could allow water to soak into the foam surrounding the side air bag inflators.
If that happens, the inflator could rupture and spew metal fragments into the vehicle.
If you own one of these vehicles, you can check the VIN number to see if it is part of the recall on the Audi website.
