We have a 2003 Santa Fe and heard a loud pop and the front end of the car looks like it dropped down and it would not run is there an air bag ride on these cars that the air bag could have blown?

The 2003 Hyundai Santa Fe does not have air suspension; instead, it typically uses traditional coil springs or struts for the front end. A loud pop and the front end dropping could indicate a broken spring, strut, or other suspension component failure. It's important to have the vehicle inspected by a qualified mechanic to determine the exact cause and ensure safety before driving it again.
