Yeah, I just had my 10,000 mile free oil-change/checkup on my 2014 Platinum yesterday. The dealer was not happy that I had non factory floor mats that could not be anchored down on those special locking pins. This check is actually in their list of to-do's, and so I was duly warned and notes entered into the records. I understand since the big lawsuits regarding jamming gas pedals, and Toyota found cases of floor mats moving up and causing gas pedal jams they have to protect themselves now.
