I had to have the left front (driver's) seat replaced in my 2005 Prius. A coworker noticed that the internal metal part of the seat back was poking against the back of the seat (he was in the back seat). I took it to the dealer that evening and while the service rep was looking at the seat, I sat in the front seat. When I got out of the car, the broken spring poked through the seat covering. The dealer then ordered a new seat. I waited about a week for the seat to arrive at the dealer. It was then replaced. Good as new.
