I am having an issue with my 2006 HiHy.

I have noticed off/on this issue, though it is more prominent now. Whenever the car gets wet--car wash or rain--the radio and NAV screen will stay on even after I shut the car off and take out the key. At first, it would only be a few seconds or so.

Recently, I returned from Chicago to find my car dead at the airport. It was jumped and ran fine, but was dead again the AM. I took it to the dealer and they found nothing. I took it back the next day for the same issue. They kept the car for 3 days and found nothing. Of course, by then it was all dry.

Today, it poured over here in the NYC area and again the car in not shutting off. I have left it overnight in my garage with the hood up. I need the car for the next few days so I can't bring it to the dealer. I plan to bring it back later this week.

Anyone else seen this problem? Any ideas?
