Service interval is fluid change every 30k miles. I'd go show that to the dealer. Did a bunch of fluid gush out when you pulled the plug? That almost looks like the diff was dry. Also, any burnouts/donuts, etc?
FYI, there is no 'rear diff temp light' nor OEM active cooling system for the rear diff. For $1000 you can install a diff cooler pump and core.
