This particular model of Audi Q3 has poor quality break pads and rotors, if you live near the ocean like me in miami beach, the breakes get damaged at only 8,000 miles intervals and they can fail causing an accident. I reported the issue to dealer and manufacturer, and they have fully washed their hands. They are aware of the issue, and have not issued a recall. I am in the process of retaining class action counsel to pursue class action litigation.
