I drive a 2007 Toyota 4runner sr5 and believe it has the same issue with brakes as the Toyota prius. When I try to brake on a bumpy road, the brakes do not properly work when I have to stop going more than approximately 25 miles per hour. The car makes a beeping noise then the car's brakes fail, then they overcorrect by becoming extra sensitive once off the bumpy section of road. This has happened on numerous occasions - I was just not sure it warranted a complaint - I was not sure if that was normal. I do not feel safe driving my car on bumpy roads as it is not safe.
