Does anyone know if there's some kind of blinker problem with the hyundai sonotoa's?

I was coming back from lunch and saw 2 of them with their blinkers going all over. First the right for a few then the left then right again for a few then the left for a few then it would goto the right one for one and then the left for a few more, back and forth. People weren't turning, they weren't going unusually slow... other than mechanical failure I can't see what would have caused that. The 2 cars were seen at 2 diffrent times from the time from the restruant to the parking lot of work. :thinking:
