Left my car there to be repaired they gave me a rental told me the part was not in stock then 4 hours later got a call my car was ready. I told I would pick it up on Saturday I asked them to do an oil change since winter coming in and they already had my car and told them multiple time to please replace the battery in my key . I have had this car since March Dislike everything about this car Drives with no power but they can not seem to find a problem oil leak they changed the pan and the gasket. Then the car smelled awful it had a bag underneath the car it was not from me Since March I have driven my car a total 15 hours a week. So the last 6 weeks had to drive around 45 minute on Parkway all of the sudden I noticed a leak.and they told me that it is a one time service gesture so I'm assuming it was my fault. My car was delivered all dirty on seats and When the sales person was bringing the car to me I checked car fax the car was in an accident front and back immediately I called him told him I no longer wanted the car he tild me he was on his way and the car had warranty any issue. Well I'm stuck with a Lemon and it's sad for a working woman with kids got stuck with this car.And if I want to get another car first thing is money down.
