What is your question?
humming / vibration coming from front of vehicle @ 50 mph in 5th gear. Heard that Toyota did issue a TSB on this type of issue concerning the a 'gear' problem in some of its transmissions. Additionally, have had the chance to discuss this with 2 other Highlander owners who do not experience these symptoms.
What makes this problem better or worse?
keeping it below or above 50mph & out of 5th gear
How long has your 2015 Toyota Highlander had this problem?
a few weeks

Hello, I'm not seeing a transmission noise related service bulletin for a 2015 Toyota Highlander. Which engine do you have? Have you checked for possible axle or wheel bearing noise? Hands on evaluation is required. What is the question regarding "dealership service centers covered" -- are you meaning do they go through the same certification process?
