Engine coolant flush. Had appointment booked for first thing that morning. Dropped vehicle off at 7:30 am and was advised the work was done between 1:30 and 2:00 pm. that day. This is not to reflect on the service adviser, but rather managements need to do a better job of training and assigning work so some small thing does not take up 3/4 of a customers day. I could have had this done at any lube shop for less money and performed in a timely manner, but chose the dealership instead.
