I bought a new Audi A4 4 months ago. When I bought it, the car was fantastic to drive and had no issues. However, a week into driving I felt some vibration through the steering. When I complained, I was asked to bring the car in. Once checked, they said they couldn't feel any vibration and dismissed the claim. After about 2 months I also started hearing a very high pitched noise from the right side of the car. This time the dealership said it's consistent with the other cars for the same model. I went on to complain to Audi Australia. They sent a rep and once checked, they confirmed they could feel the vibration and hear the noise. They kept the car for 3 days and told me the issue was rectified. Once received, I drove the car and it was no different. I was then told they have checked with Audi Germany and this is consistent with the car and there are no issues. I was further told the car is under warranty and so I have nothing to worry about. To me, I think this is a rip off and should receive a full refund and compensation for it under Australian consumer law?
