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.

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.


Price seems reasonable.

Just to give you some pricing. This is in Canada.


Oil change that I supplied the parts for, oil filter and oil. The labour came out to $72

Brake fluid flush was $130

So to get all those services done for $500 IMO is a good price

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.

Ugh, too late. Am currently posting this from a coffee shop because I was evicted.

$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.

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.

I would have done all that by 30,000 miles on the 3.7

Brake fluid every year.

wouldn't you have to get it to the dealer before the "miles remaining" goes to 0 or every 10,000 miles for warranty records?

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.

The maintenance manual only says inspect every 10,000 miles. It says to replace transfer and differential fluids at 20,000 miles or 24 months if using a car top carrier or driving on rough or muddy roads or what they call severe driving conditions.

But I agree that those fluids should be changed on a routine basis and not just inspected periodically for 120,000 miles as the maintenance schedule indicates for normal driving.

Aye I had the section screen captured when I posted but it didn't attach the image apparently.

Problem with that is the manual doesn't define what a "Rough" road is, it could be as simple as uneven pavement with minor elevation changes
or potholes every 5 feet and your teeth getting knocked out.

The run flats ride bad enough that anything but the most recently paved roads can feel pretty harsh,
besides you said "Factory maintenance schedule makes no recommendations for changing these fluid".

Which would be false as it does make recommendations for changes.

Good point. I should have said "Factory maintenance schedule makes no recommendations for changing these fluids during normal (non-severe) service conditions."

Severe service conditions usually include conditions that most of us don't experience, such as regular use of a car-top carrier or regular use on muddy roads - you should have bought a pick-up. The rough road inclusion puzzles me. I take it to mean gravel or dirt roads as it is kind of grouped together with muddy. If they mean the normally accepted irregularities encountered on paved roads, then they should just make the fluid changes a regularly required maintenance item.

So does sloshing about in the case cause these fluids to foam, or are the fluids degraded from the gear teeth being slammed together as road bumps are transferred to the half shafts?

Hah it's all good I was mostly just nit-picking, I'd probably agree that any road where slower speeds are advised is probably a good rule of thumb for "Rough roads"
The wording even includes a "roof-top carrier" as a scenario where the fluids would need to be changed, which is odd considering at worst it hurts your MPG
due to wind-resistance and drag on the car.

Very much sounds like they should have just made it a regular maintenance item. Hah

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."
