2018 Audi Q5 recalled - update

Audi Australia has recalled two 2018 Q5s, over concerns their rear brake pistons are incorrectly coated. UPDATE, 08/08/2018: Audi has added another car to the recall. An updated VIN list is attached here.  According to the company, the issue could cause a long brake pedal travel and reduced overall braking effectiveness. Less effective brakes, obviously, pose a hazard to the driver and other road users.
