I have had numerous problems with the car since I bought it. The dealer that I bought the car from said he had fixed the problems, but hadn't. I asked for my money back because I haven't had the car for 20 days yet, and he refused. The car has been broken down ever since I bought the car. The dealer will not do anymore for me. He did not tell me there was anything wrong with the car when I bought it. No safety defect listed in the summary. *Ak
