Mine didn't do it before, even on trails... But on a recent drive to Kentucky from Virginia, it happened. Eventually, the power steering quit working and my electrical system went a little wild. Fog lamps and dash lights started to flicker and I got a charge system red indicator light too.
The dealership initially thought it was a faulty power steering pump so they replaced it. The problems continued... Turned out to be my alternator. Apparently It was kicking out too much juice and messed things up.
They just replaced it and are telling me it's good to go now. I guess I will find out shortly.
