Hi and welcome to FixYa,

Offhand, definitely an electrical issue. Some ideas to check, consider and/or explore:

• IGN switch - check for loose, corroded or heating connections. To test, under normal usage of the vehicle, should feel warm but not overly hot. If so, then possibly loose connection;
• fuse/relay box - check for loose, corroded or burned terminals, holders, clips and connectors/pins. Use an electrical contact cleaner and spray. It may also be necessary to scrape to remove burnt marks/corrosion;
• fusible link - the battery would have 2 wires connected to the + terminal. The big wire goes to the starter, the smaller of the two is the electrical systems main wire. This normally goes to the fuse/relay box. Check for frayed ends, loose connection, corroded terminals. In some instances instead of being at the battery's + terminal, it is connected to the end of the big cable down at the starter motor.
• ALL connectors with big wires - these carry the main +12 either as always ON, ACC or IGN. If a connector has a wire bigger than the others, check them. It may be necessary to disconnect to enable you access to the inside pins/terminals. Scrape them clean.

you need to go to the Hyundai service center they can reset the radio I believe this is a security feature, you may be able to call the service center to find out the procedure to reset the radio, it is the original right ?

SOURCE: ESP & ABS light comming on all the time

you should have the ESC/ABS module scanned for DTC's.

here are the 2 most likely causes.

1. low brake fluid
2. sticking/siezing brake lamp switch

at the dealership i see the brake lamp switches go bad left & right on a lot of the newer hyundai's. are your brake lights working?

Sounds like you have a bad ground. If it is not that you must have a gremlin.
