There is an Inertia Switch, but that only activates if you crash at speed.

It is most likely the fuel pump relay. Lots of information in the link

..

the sender is bad in the tank or wires go it wrecked.
no year car told nor what country it is.
no engine told size.
Hyundai Santa Fe, real name. , year 2001 to now USA< is it USA?
not told.
parts on cars are not the same on all engines used..
FWD or AWD version, or post the VIN.
22 years made with over 40 engine world wide, gas and diesel.
yes newer cars cut fuel with AIR BAGS deployed.
no year told at all, must we guess what you drive?
it runs so why ask for" I'm curious if there's an inertia switch."
those all cut fuel dead ending crash and burn, even lost spark cuts fuel dead PCM logic.
focus on the fuel sender.
and fuses..
or scan the PCM, omg it says sender is dead, I BET IT DOES.

is fuel pump coming on -----start checking to see if pump is working and that it and or wiring not damaged

it does not have one. Ford is the only manufacturer that uses one.

Bad connection in the dimmer control between hi and low beam. Replace the dimmer switch electrics.

What you want to do is look for this:

Also, in the attached diagram you are looking for item #16. If things get stuck for you, specifically you are looking for the location of the FV-7 valve. Go to the attached diagram first. Find that relay and see if there is something there!

IS LOCATED ON SWITCH WHERE YOU TURN ON HEADLAMPS GRAB THE END OF THAT SWITCK AND PULL OUTWARD.

If you have a reset button on your car (some do and some do not) it is located in the rear, usually on the passenger side behind a small panel....in the Sonata it would be in the trunk. These buttons normally only trip after a rear end collision.

The relay will be in your fuse panel. Also check the fuel pump fuse. The fuse panel should have a map on the inside cover to guide you to the right components.

The most common problem, however, is a bad fuel pump. After you eliminate the fuse and relay, that will be your next check. You can use a voltmeter to see if the fuel pump is getting power (key turned to ON position)- read across the fuel pump power connector- commonly under the passenger seat.

first try a new light ,maybe both of your low beams are bad ,check fuses.maybe your dimmer switch is bad
