Since April (2 months after having vehicle serviced and yearly inspection) a loud grinding noise when I brake. Sounds like it's coming from the rear. Took it in to dealer and they could not replicate the noise, of course. Said they put it up on the rack and looked at the brakes and said the brakes are at 75% so they're sure it's not the brakes. As soon as I got it home the next day the noise came back. It's so loud that other drivers in a car next to me can hear it because I get weird looks sometimes. This is really annoying but also scary not knowing if your brakes are going to go out at any minute.
