My wife has a 13 Prius persona. There is a rattling/banging sound coming from the front end on drivers side only. Car has not been in any accident. Toyota dealer has looked at it twice. First time could not hear noise. Second, he heard it. They looked at everything and then stated that it was the ABS Brakes testing. Has anyone heard this before? It sounds like something is loose- that is the best way to describe the noise. It happens fairly often, too. Never happened with my 2012 Prius model two when we had it. Any thoughts?
It actually happens all the time- off & on, but not neccessarily when going fast or slow, stopping or anything. It could just be driving straight. Its all directions, all kinds of driving.
The brake backing plate is known to bang against something on bumps. Sounds like something is loose. Could that be it?
