I have a brand new 2014 hyundai santa fe sport turbo AWD, it has 5,000 miles and randomly over the last 2 months I have owned it, the electronic dash will say "goodbye" and go black while I am driving then turn on a few minutes later and say it's doing a system check. It happened to me 3 times today within 20 minutes. It is scary to me since I keep thinking the vehicle is going to just shut off. Most of the time I am driving on the highway. I brought it to the dealer about a month ago when it first started happening and they looked at me like I had 3 heads. They kept the vehicle for the day and said they couldn't get the problem to duplicate and when they called the hyundai tech line they were told they have never heard of this problem. It's just very frustrating that I have my first brand new vehicle that I paid a good amount for and it is having these problems already. Any tips would be helpful as I'm sure when I go to the dealership again tomorrow they will be able to do nothing to help me.
