I purchased a 2012 Genesis V-6 w/tech package last July. About 3 weeks later I went through a car wash. A few minutes later I lost all sound. Turned car off and back on - no luck. After getting home and letting car sit overnite the sound worked next morning. Dealer could find nothing wrong. No problem for several months. Yesterday the same thing happened after going through car wash. Again, sound returned after sitting overnite. Anyone else have this problem? or have any ideas? Obviously water must be getting in somewhere and causing the problem.
