I have owned a C for almost 8 months. Happy owner except for clanks that seem to come from front brakes when passing over botts dots or pavement imperfections. It has been that way since day 1. I'm aware a TSB exists for Gen 3 Prius brakes but seems there is nothing for C nor any comment found in Priuschat from othwr C owners. Someone else having this issue? Should I be concerned? I would wait the next scheduled maintenance unless it is a serious issue Sent ?
