Rear End Noise 
 Overall I am satisified with the car. My gas mileage, having driven 10,320, is44.2mpg which is GREAT. The rear storage is more than adequate for a small car. Handles and ride just fine. Our BIGGEST problem we are having, with no fix available at this time, is an increasing high pitch noice coming from rear. The noise has been increasing in loudness and duration as we add mileage. It now is occurring at times when applying breaks. It is more noticeable when it is damp, but has at times made it when dry. I have had it back to dealer 3 times and this last time was informed Toyato is aware but does not have a fix. So if you are considering proceed with cation! Frustrating for sure!
