Purchased an Audi Q5 2019 with only 14k miles on it from sales rep Kit. 3 days after buying the car the Check engine light came on. Contacted Kit at first but he did nothing to help. Then tried to contact the General Manager but nobody returned my call. It is now a month since my purchase and still dealing with the same issue. Took the car to the Mount Vernon Service center who are now trying to assist me. My thing is If I purchased a new car I should not be dealing with these issues and I m pretty sure if I was a white person who just purchased a $45k car the service would ve been different and I would ve been provided with a solution right away!
