text: I have a ZDX The car has run excellent and I love all the features A few days ago the car computer reported that it was time for an oil change I called the service center and they made it very easy to set up my appointment I was kept well informed throughout the process of my service I would have given them stars but I had to fight to get the oil change for free When I bought the car I had it negotiated to get years of free oil changes I felt that they should have documented in my file about the oil change instead of putting it on me to prove that they has made me that promise
