Hennessy Lexus of Gwinnett

I purchased a car from Hennessy Lexus on Monday, 9/12/2016. Jack Ross was my salesman. Before we closed the deal, we took the car on a short test drive (Maybe a few blocks). At the time, I did not notice anything wrong with the car. Once I got on the interstate, heading home, going about 60mph, I noticed a winding sound, the steering wheel had some vibration, and the car was pulling to the right. I woke up the next morning and drove all the way back to the dealership. Mind you, I live a hour away from the dealership.. As soon as I arrived to the dealership, I ran into my salesman Jack Ross. I told him what was going on and he suggested we take it for a ride so he can see what's going on. We test drove the car, he confirmed he heard and seen everything I said was wrong. When we got back to the dealership, Jack Ross said he was going speak with a manager to see what they can do. He came back a few mins later and stated that the manager said they are not going to fix the issues because they gave me a good deal. A "good deal" has absolutely nothing to do with selling a person a car that has mechanical problems. I asked Jack Ross to get the manager he spoke with to come speak with me. He left for a few minutes and came back without the manager and stated that the manager said he will not fix it and that they can take the car back if I did not want to fix the issues myself. He said the issues will cost me only about $500. I told him I don't want to give the car back, I want them to fix the problems that should have been fixed before they put the car up for sale. They refused. I was really surprised getting this kind of service at a big professional dealership like Lexus. I am very unhappy with the customer service. I did not want to argue, so I left with the car. When I got back home I called several times leaving several messages to the managers and no one returned my call. I emailed them Friday 9/16/2016 and the manager Brad Zeller responded Saturday morning 9/17/2016. He stated the car was sold as is and that they will not fix it. This is unprofessional and unacceptable. I filed a complaint with the Better Business Bureau and the Consumer Complaint Center. Currently waiting for a response.
