He’s probably not wrong. My 09 failed at 95k but Nissan replaced it under extended warranty. The dealer tested the fluid at 60k and said it was “fine” and I knew no better. Since then I’ve been diligent on annual spill and fills. Heat breaks the fluid down and there’s the issue. My wife’s new 24 cvt temp runs about 40 degrees warmer than my 18 and 21. I went straight back to the dealer with many questions about this and the tech got the factory service manager on the line to verify my findings. The reasoning was to burn off any condensation that may accumulate and that the cvts on the newer ones have been beefed up to compensate. I can’t say that gives me the warm and fuzzies, so I’ll be doing 20k services on this at most. A scanguage or any tool that shows tft, 4qts of ns3 and an extra half hour while doing an. Oil change for piece of mind. For reference, my 18 rogue and 21 Altima run 170-185 depending, while the 24 runs 205-220 no matter the weather or terrain.
