I purchased my 2016 Elantra last week and it had zero issues. I took it back to the dealer so they could install a hub cap, got my car back and the clock doesn't come on, the trip/mpg/mph resets every time I turn off my car, the key stopped working, and the interior lights do not come on when the door opens. Does anyone know what could be the issue? I tried to have the dealership look at it before I left but the mechanics all went home and they don't open up until Monday. Btw, the memory fuse is switched on.

 

I would have been at the dealership 1st thing Monday morning.What did you wind up doing and what was the issue?
