Any Prius owner experience this clanking sound coming from under the carriage? Like a metal rod tapping the concrete floor or similar? Ihear this when I pull the car in to a covered parking garage. When I look under the car, I couldn't see anything suspicious of making that noise. Could it be a loose tie rod? (I don't feel any steering wheel problem either). Car is under 10k mile, Going to take to the dealer to figure it out.
