Without any warning, after driving brand new car for only 15000 miles, the brakes had a catastrophic failure (right rear wheel). luckily i was in a service road otherwise this would have been catastrophic. i got the car serviced 2 months ago and everything was fine (just some rusting on the brakes) so the audi authorized dealership let me drive saying we should look at it next year. the car is right now at that same dealership and i also worry they would tamper with it or have some other issue in it.
