This is crazy, just picked up this 2002 Santa Fe... The radio suddenly turns on by itself while driving and i can assure you that it was shutoff prior to driving.....

It's inside the radio... replace radio with a "float" unit from dealer.. may have to order for you.

First one I had, I thought it was unusual,, tech assist said yes, replace the radio.. I have seen a couple in Sonata do it also.
