Most likely the o-ring seal between the torque converter and the transmission is going bad. Get that transmission rebuilt pronto before serious damage is done! But first, have a mechanic drop the transmission pan and look for signs of a very thin silvery film coating the inside of the pan. If found, then the transmission definitely will have to be rebuilt, and the torque converter will also have to be replaced since embedded metallic particles in the old torque converter will eventually come loose, due to wear of the clutch plates within the torque converter, and eat up the rebuilt transmission. Now, here is the deal once the transmission has been rebuilt:

Change the transmission fluid and filter once a year -- no matter what! If you do this, then you should never have any more problems with the transmission.

SOURCE: PROGRAM KEYFOB FOR HYUNDAI SANTA FE

This is from the factory service manual of your car:
There is no onboard programming procedure for this vehicle. This vehicle requires special equipment be connected to the vehicle to program the keyless remote. Translation you need the dealer to do this.

The vehicle will run fine for a while until that cat goes out all the way, the only thing that might get you away cheaper than $1,000 is a wrecking yard cat, but then you still take risks. If the cat is bad its bad nothing to do but replace it.
