Sounds like it could be a ground issue.

Is it in backwards?

Huyndai's are netorious for transmissions doing funny things if the Throttle Possition Sensor is bad. Not an expensive part that you could probably change yourself. It is an inexpensive try, if it does not remedy the situation. Also, the computers regulate shift patterns. You might unhook the battery and leave it unhooked for 30 min. or so, and see if it will re-learn shift points.

raise and support the rear of vehicle, then disconnect all fuel, vacuum lines, electrical wires that go to the fuel tank. disconnect the fuel filler neck from gas tank, support the fuel tank with a jack, disconnect the fuel tank support straps and lower tank looking for anything that you may have overlooked to disconnect.

You have a bad ground. Most are behind the side kick panels.

somethings wrong w the module that controls that area--a shop manual can xplain it-library has them-or bring it to a private shop w some experience

the same is happening to the out side but they dont recall it if they dont have to! lose too much money!

it might not have some windshield fluid...add some water in the reservoir for the windshield and see if that works...
Good Luck!

Only Ford products use a cutoff switch for the fuel system.

Do you have electronic door locks? If so, check your fuses-simplest place to start. Next I would take the lock out on the inside, it could be a bad ground wire. Good Luck.
