We bought the new XJF this summer and it's been in the shop three times because of the computer. The last time they had our car for five days and when my husband picked it up it was dirty and before he made it out of the service drive the radio stopped working. He pulled back in and spoke the the service manager who refused to take the car back and said he could do nothing and that we should call Jaguar of North America. Mind you this is not a cheap car yet when we get it serviced we get Ford's as loaners instead of a comparable car. All though the Ford did work and had way more functioning bells and whistles then the Jag. We also purchased a service that would take any dings out of the rims. We have asked on all three visits to have the rims repaired and guess what they have not been. When taking our other cars in for service at Mercedes we literally get FIVE star service which is what we expected from Jaguar but have yet to see it. I did call Jaguar of North America and they were shocked at the poor customer service coming from this dealership. The service people all are comedians and make rude condescending remarks about their lack of loaner cars and the respected issues with the computers. They should invest their time in fixing the problem. Looking forward to hearing a resolution from JNA since the dealership cannot preform.
