I recently took my 2015 Q50 AWD (73k miles) to my trusted Japanese specialist mechanic for an oil/filter change.
In addition to the oil/filter, they recommended a transfer case fluid flush, differential fluid flush, and brake fluid flush. Total came to $500.
I agreed to the services because I trust the shop, and I'll likely keep the car a few more years, so it felt like a good investment in the longevity of those components.
But, are these services worthwhile? How about the pricing?
Factory maintenance schedule makes no recommendations for changing these fluids (at least for my 2018). I don't think you can go wrong having it done (unless the shop uses the wrong fluid). In my opinion I don't think you overpaid for those five services lumped together, but then again I am used to dealership prices. A good independent shouldn't be all that far behind on hourly labor rates though.
You should give your manual another read Transfer-case & Differential fluid inspections are recommended every 10,000 miles and changes required every 20,000 miles in most scenarios.
It may not be a required maintenance item but it's something you want to keep up on
if you plan to drive your car past warranty.
With those miles I think that was a good thing. I had mine done at about 30K miles. Got those initial wear particles out. I'm probably good for a long time now.
Brake fluid flush/replacement should be done every 2-3 years. Since the brake fluid absorbs moisture, replacing the fluid prevents corrosion of the wetted parts and maintains brake performance.
The differential service (+ front diff & transfer case for AWDs) is a good preventative step after a suitable break-in period, as the metal bits from the gears meshing will attached to the plug's magnet and be held until the fluid is changed.
If you track your Q, getting the transmission fluid changed is also a good preventative step - when @JohnInNH had his fluid changed as part of the Level10 Upgrade, the fluid after 20k miles showed signs of overheating.
I do my own oil changes every 6k. I just bring it in to dealership every 16K scheduled so its on file that an oil change was done for warranty records.
Pricing varies so dramatically from place to place, you really have to compare it to other shops in your area. It never hurts to get fluids replaced. Unless you didn't pay your rent to have this service done I think you're fine.
$500 is about right, my local Nissan Dealership charges $109, brake fluid, Transfer case $300, oil change $59. djrise $72 for oil change labour, I would do it myself. LOL.

I don't know if it was the fluid that showed signs of overheating, it may have been something else? Like some mechanical parts. Pat just said; "I found signs your transmission was overheating.", "So I replaced the pump with one that has a higher output, that will keep your temps down."
