Low oil level in crankcase? Check that out since hard braking will cause the fluid to move to one end and perhaps give a low false reading.

The switch you speak of , as far as I remember was for accidents where cars rollover. This was to prevent fire. I believe in your case because of the area ,side front of car, your problem lies with your crankshaft sensor. Sometimes all it takes is a jolt and these sensors give up there life. This sensor on your car is located on the front left side of your engine, in the immediate area of your accident.
If you can , try to get some body to pull up the codes from your computer. These codes will tell you what the problem is with your car. Please let me know how you make out. GOOD LUCK.

Hello! Was the car in a collision? Your vehicle is equipped with an "Inertia Switch"...It trips when the auto is in an accident to shut off fuel flow...It is located in either the drivers or passenger kick panel...It has a Red button that needs to be reset...See picture of part below...Guru...saailer

Of course this is only the cartridge, you have to transfer the spring, and the top mount of the existing strut. You need a pair of coil spring compressor to do the job. The basic procedure to replace a strut is:
Remove the top nuts that secure the strut assembly to the frame mount inside the engine compartment. Do not remove the center nut.
Mark the lower strut mounting location on the hub for installation reference. The alignment will be close if the new strut is installed in the same position.
Remove the bolts that hold the strut assembly to the hub.
Remove the strut assembly from the vehicle.
Mark the top mount for installation reference. Using a side mounted spring compressor, compress the spring and remove the top nut and retaining washer. Pull strut assembly out from the bottom of spring.
Slide the new strut assembly up into the spring and reposition the top mount onto the spring in the same position that it was removed. Install the retaining washer and top nut.
Tighten the top nut to the manufacturer's specifications and carefully remove the spring compressor.
Place the strut assembly back into the vehicle.

could be the driver side master window switch... if the driver side window switch assembly is broken then the windows will not work... try using a test light to see if you got power to the with and and ohm meter to check all four switches on the drivers side

Try running a ground wire from the rad support to either the engine block or directly to the negative post of the battery.Check your harness to see if any loose ground wires didn't get hooked back up during the repair as well.

Since you\'re looking for FREE information, we can\'t diagnose your problem without first PHYSICALLY looking at it.. .ya think? Take/tow the vehicle into a Hyundai Service Center (dealership), pay the diagnostic fee. They will tell you EXACTLY what the problem is and what\'s needed to fix it (parts, labor, tax, time-frame, etc.).

The problem is in the starter system circuit(s). Check/inspect the condition of the battery cables & connections to the starter & grounds - replace/repair/correct as needed. Next, inspect/check the starter clutch pedal position switch - repair/replace as needed. Next, starter relay operation and connections. Of course, inspect/check all wiring connections. The burglar alarm relay is 'normally closed' contacts unless the alarm is activated - in which case the alarm must be 'reset' (deactivated) to re-close those contacts. You mentioned front end collision damage - definitely inspect all wiring there - repair/replace as needed.
