Once again, I leave the service department with a low tire. After I specifically told my service advisor(Greg) that I had a low tire. He told me, "We inspect the tire pressure on every service." I politely informed him that his statement was incorrect and that the last service that I had performed by them was about 3 months prior and my tire pressure was not checked, among other things crucial to the specific service it was in for. I find it disturbing that something as simple as checking the tire pressure is so hard to accomplish for their service techs.
