I had free oil changes with my Tacoma when I purchased it for like 2 years I think, so I would take it to the dealer to take advantage of that. No loaner vehicle at the dealer, so I would take their courtesy shuttle back to my house...only a few miles.
I took my truck in on a Saturday morning, figuring they would have the truck for a few hours at most, took the courtesy shuttle back to my crib and went back to sleep.
Called around Noon, still not done.
Long and short of it, they had the truck for like 8 or 9 hours for an oil change. I didn't get the call until around 4:30 in the Afternoon that it was done.
Pissed me off something fierce, and never went back again. Toyota can stick my remaining two oil changes up their ass.
