I own a 2007 XK Convertible that has been nothing but trouble. The car fails to start at least twice a month. In the first 10,000 miles I have had 2 battery replacements. I have been afraid to drive it a long distance from my house and really havent gotten much use out of it. The Jaguar service department where I bought the car cannot find the problem. When I complained to corporate headquarters they said they could do nothing for me. In fact when I told Jaguar Credit I was thinking about withholding a lease payment because they could not fix the problem, the response was that they would damage my credit rating. I spent a lot of money for a poor quality vehicle and an organization that simply doesnt care. Has anyone else had this problem?
