Arrived for my 10a appt for oil change and tire rotation (service B) for our Odyssey and was asked to take a seat at waiting room. Service advisor must have been busy as he never showed up.
2.5 hours later I had to ask another service advisor the status and he said it would be ready shortly. I wasn t charged for oil change (buy 3 get 4th free) but tire rotation was not done. Therefore, oil change took over 2 hours (w appt).
