I just hit 90 k and I honestly don't trust the whole "lifetime" fluid thing. I did a drain and fill on mine, that fluid was DIRTY. It helped a little on the lag and the kind of bogging feel the tranny has been giving me, but it still does it and is now seeming to get worse. I LOVE the car, but I cannot lie it's scary. I don't have the 4-7k to replace the CVT in this dang thing if something happens.
The only thing I can notice is the bogging feeling, it's kind of like the feeling when you drive a manual and you let the clutch out early without enough gas. That sort of bounce . It's mainly at slower speeds like in traffic.
My fingers are crossed. I read that the earlier generations of theCVT have an issue with one of the valves inside the CVT sticking and causing the exact issue I am having, but it's not a recall -_- #Irritating. They are aware of the issue, but are not going to fix the ones that are experiencing the problem? grrrr/ lol
