After parking on an incline, in cold weather, with the emergency break on, then starting up the car and driving slowly, the rear tires make a grinding noise. I have taken the car in to the dealer twice to address the issue, and they have completely replaced all the break equipment and still the issue continues. They have suggested that I don't need to use my emergency break when parking the car.
