2021 GENESIS GV80 Unknown Or Other Problems

I have genesis GV 80 3.5 AWD. They gave 3 year connected service feature then after we have to pay every year.

We took the vehicle immediately to the dealer where they proceeded to tell us there is nothing wrong because the diagnostics came back fine. But now this exact same thing has happened on 7 different occasions after driving a little over 1,000 miles. This has happened on the freeway, on busy intersections and feel unsafe to drive. On one occasion, we were almost hit from behind because we stalled making a left at a buy intersection. I took it back to a Genesis dealer and one week in their...
