Two problems related to brake grinding noise have been reported for the 2008 Toyota Prius. The most recently reported issues are listed below.
I have a 2008 Toyota Prius and my problem is with the braking and the anti skid coming on even on dry pavement. I have also a noise that comes from braking when the car is stopped. When you press on the brake it makes a clicking and grinding noise even when the car is not going. I have had it in about 4-5 times for these 2 problems and 3 times they bled the brakes and 2 times they changed the actuator. This problem started about 3-4 months after I purchased my 2008 Prius.
Every time we step on and off the brake there is a grinding noise. I have visited 2 dealerships to help identify the problem at least 7 Toyota people have verified the noise but are unable to determine the cause. The local rep originally said I hear it, don't know what it is and therefore cannot fix it. After I contacted their corporate hqs in CA he now says it is a normal noise. Without explaining cause. This is a 2008 Prius vehicle. Friends who have 2005,2007 and 2009 Prius' do not have this noise. It is a life threatening problem until the cause is determined. Since it involves the brakes. I have a detailed list of all the actions I have taken, which individuals verified the noise and the individuals I have spoken to concerning this problem. Is it a faulty electric motor or controller between gas and electric motor? this vehicle uses the electric motor as part of the braking system. Did the vehicle design put a noise in 2008 and take it out in 2009? please help me have Toyota examine the vehicle and determine the cause of the noise and fix it. Please help before someone gets hurt. Fred zivitofsky.
