The only service I had done was at the dealer about a month ago for the 2 recalls and a couple of TSB's. But none of them would require a wheel to be pulled. But who knows, the vehicle was out of my sight so maybe the tech thought he would check for wear on the disc brake pads. But with only 4,600 miles on the vehicle, I doubt they would waste the time to do that.
