I went to the dealership to get the oil change at 6:30am this morning. I had an appointment for 7am time and was the 5 car in line before it opened up. I was there for 2 1/2 hrs and noticed people arriving after me was already done with there oil change. I got with the employee that done my paperwork when I arrived ,he went in the back and seemed to not be able to find where my paperwork was to see if and when the work is done.he came back and told me the oil has not been changed yet . I was told the car was not sent to the Express lanes because it revved up when that turned the car on , they never even told me they were looking at this until I asked why it wasn't done yet. He said it will only be 20 to 30 mins more ,guess what i didn't get out of there till 1 hr later. If i didn't have free oil changes and a warranty on the entire car for life i would never go here. SORRY.
