I own a 2013 3.8 genesis with full tech package. Car has been flawless for 135000 miles. Yesterday come out of gym, open door, no chimes, no genesis emblem, no nothing. fob cant open or lock door. trunk doesnt open etc. Battery is 2 years old. I go through a bunch of stuff, then I push gas cap release button, car powers up, drives and starts numerous times without issue. This am, starts up like nothing is wrong. I go on about my day, bunch of driving cycles without issue. Then again same thing occurs, no power to car at all, like it has a dead switch. So first thing I do is push gas cap release button, car powers up. Thoughts?
