 I have a 2017 Q7 and the brakes squeal. This sound has been present since we purchased it as a new vehicle. We have called Audi USA multiple times and they claim fault and have been absolutely useless to help us resolve this issue!! This is my second Audi (A8) and given the performance I was expecting, this has been very disappointing. With this type of service of a new vehicle, be careful making an Audi purchase!! I sense Audi is just waiting for the brakes to wear out and charge us for new brakes. Anyone having a similar problem?
