I was told the day before that my appointment time would work for me because there were parts available for a recall repair. When I got there the parts were not there, a mistake, but would be. This caused my return of the car to be pushed to much later in the day. No acknowledgement of a mistake or sorry for my inconvenience. I have to believe the work was done correctly, but am disappointed about the delay for me.
