So this has been happening for a while now and I can't remember if it has since I bought it but everytime I brake from a high speed and about halfway into the stop I can hear this noise which I can describe as a grind/buzz. It doesn't do it when I brake in traffic or whatnot but only when coming to a stop from say 30mph or above. The car brakes fine but the sound is just troubling to me. Anyone else have this? I'm wondering if it's the transmission downshifting or just the hybrid braking system. I've never had a hybrid before so I'm not sure. Thanks!
