Happened today. Backing up the driveway at my parents house. They live on a cauldisac. I was turned around backing in to the driveway. Then felt a weird shake in the steering wheel. Like I ran something over. But there was nothing in the driveway. Later on I felt it again on a right turn. When I started to straighten the wheel when coming out of the turn. When I was parked I turned the steering wheel. It was kinda loose to a point. Then got tight. Wonder if I have problem with the steering assist.
Mine is an 08 2.4 with about 4600 miles.

Certainly sounds like something the dealer should check out....I would say there is gremlin in the steering assist.
