Well I just wanted to go on the record saying I officially have my first rattle in the prius. It has about 1000 miles on it. I was driving to the store today and decided to turn my radio off and just listen to the car. Thats when I noticed a rattle coming from the front passeneger side, possibly the door. Now that I know about it, it is driving me crazy! Its all I hear now. Unfortunatly I cannot pinpoint it, whether it is the door or part of the dash. If I were to bring it in does anyone know how toyota would go about pinpointing it and fixing it? How much would it cost? Anyone had similar problems? Thanks for any advice/input. (Edit) I also wanted to mention the rattle is only noticeable on rough roads.
