I have a 2012 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 5-stars, but I had to fight to get the oil change for free. When I bought the car I had it negotiated to get 3-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.
