Maintenance whats right and wrong, Dealer service trust?

We have a 2018 Nissan Rogue SV AWD. It has 30K miles and went in to dealer for service. I was not available today, so they convenience my wife into services that I am questioning if they should have been required at 30K?

1: Flushing brake fluid; Brake fluid exchange using Valvoline protection brake fluid system
brake fluid dot 4 48 oz

2: Automatic transmission service Flushvalvoline transmission system (includes CVT)

  • Recommended in the near future
  • Differential or transfer case service
  • Rear differential service
    Looking at the official 2018 Nissan Rogue manual, it does not show if fluids should be changed only that they are looked at for color etc…

The Manufacture use to have millage recommended service interval with detail as to what should be checked, and replaced etc. Now it seems they leave the maintenance vague and leave it up to dealers! How ethical are they? I look at some dealers websites that have a nice detailed maintenance that show no fluid changes expect Oil at 30K up to changing brakes, transmission, like my dealer did? How does an owner understand what is the correct thing to do to maintain their pride, joy and blood and sweet in an expensive $30K vehicle? Yes 30K is a lot to us!

As long as the procedure is done properly replacing brake fluid and transmission fluid at 30K is a good idea imo. It should pay dividends in fewer repairs later. The differential and xfer case fluid replacement is a good idea too. I can’t speak to how often those should be changed though. In my 4WD truck I would sometimes replace both front and rear differential fluids daily, if I was crossing creeks.

If the vehicle is still under the manufacturer warranty, listen to the dealer.


I follow the owner manual scheduled maintenance and ignore the upsell BS.

The Nissan maintenance guide can be confusing, there is a separate chart for “Chassis and Body Maintenance”.

It shows to replace the brake fluid every 2 years.

Replace the cabin air filter every 15,000 miles.

Replace the key battery every 30,000 miles.

Inspect the CVT fluid every 10,000 miles and replace if necessary. At 30,000 how does the CVT fluid look?

Inspect the transfer and differential fluids every 10,000 miles and replace if necessary.
