Sorry. I don't know. Best to call the place where you purchased your vehicle & ask them.
I would think that they would .
If it's an OEM radio and you purchased the car new-with-warranty, it likely is covered. Hyundai warranties are pretty great. Phone the dealer and talk to them to be certain though. If you've made any changes to the radio yourself or damaged it through your OWN acts, it may not be covered. It sounds to me like a quick fix, honestly. Like a connection just needs to be tightened.
