No they shouldn't unless it was VERY serious
Lose of power or ground since all the gauges quit working.

There are many reasons why the leveling system will quit working. The first thing to check would be the brake interlock wires, one may have come loose.
If just one headlight quit working it probably burned out. If both headlights quit working at the same time the fuse probably blew.
I would look for a bad ground if the fuse is good
If the speedometer and odometer both quit I would blame the speed sensor. If only the speedometer quit I would blame the instrument cluster.
Check the fuse.
Blown fuse.
We need more info simply other than your sound quit working
Replaced the battery in the remote.
blown fuse
The best person to talk to would be your doctor.
