Toyota has dismissed this issue with the Prius V 2012. In the mornings the car will make a noise from the back wheels on and off. The noise started about 20,000 miles in the car but every time we will take it to the dealer they could not reproduce the noise and never found anything wrong with the car. Now the car has around 40,000 miles and the noise is more consistent and getting louder.

This time we researched in the internet to see if people were having the same problem. We found out it is very common. We went back to Toyota dealer, which they try to do the same thing they have been doing so far "we don't find the problem.. there is nothing wrong. The brakes look fine.." But this time we left the car overnight, after talking to several mechanics, one of them said, "yes there is an issue, I know what it is and we can fixed it", but it is not cover by the warranty. They need to change the rotors and the calipers. We have extended warranty which does not cover the rotor!!!

This issue should be a RECALL from TOYOTA and we should not be force to pay for a problem with their design. This is just unacceptable.

Purchased vehicle March 15 of 2012 and was happy till the end of May when a noise became noticeable from the rear of the vehicle. Made an appointment with dealer for the 15000 mile service and to have the noise looked into. The service was done but I was told after the dealer ship having the vehicle for 2 days they could not hear the noise. I then took the vehicle in early for the 20000 mile service and to have the noise looked into as it had became louder and more often. The dealer had the car for 3 days and never contacted me about its status. When I called I was told they found that a rear brake rotors had abnormal markings in them from improper machining and the brake pad friction material glazed. They found the rear rotors were warped causing the noise. The rotors and brake pads were replaced and it seemed the noise was gone. 4 days after getting the vehicle back the noise was back. Took the vehicle back to dealer ship and was told that the noise was something which Toyota has been looking into for months but have no solution has been developed. When I said brakes is a safety concern and that if something should happen and someone was to be hurt or killed there would be a lawsuit the tech said that would be the case, but that Toyota did not feel it was a safety problem of major concern. I was told that I would be called when Toyota found a solution. I am now driving a vehicle which I do not fell good about, nor do I have any faith in the dealership I purchased the vehicle from.
