Mine only started in February-March with 10k miles. Only when wet or there's moisture and whatnot but sometimes when it's dry. I was told I can have my pads or discs replaced within a year or 18k miles so that's happening. Anyone else's sound like this?
I would go to a different dealership or speak to someone else in service because if you feel anything is wrong with the car and the vehicle is under warranty there is no fee
