I recently took my RX350 to the dealer for a free 5000 miles/6 month service which was to include oil/filter change and tire rotation. I had only 3000 miles on it, but the 6 months from delivery was up the next day. Upon arrival, I told the service advisor that I was here for the 6 month service. After looking up the vehicle on his computer he said they would check all the fluid levels, do the AC wiring recall mod, and provide a free car wash. I asked about the oil/filter change, etc, and was told I could wait to have it done when I'd put another 2000 miles on it. I said what about the warranty requirement, and he said they would change the oil/filter etc IF I WANTED. Well, I wanted to keep the warranty requirement as well as new oil so I told them to do it. Someone else might have said ok to wait until the odometer read the required miles...BUT, if they had a warranted problem it would be the owners word against the dealer's service advisor. This may be an isolated case, but be advised, especially if you have someone else take your vehicle for service.
