There are multiple class action lawsuits and settlements with Nissan over their CVTs. My Versa with a CVT started dying around 70k miles. It had all its scheduled service. I brought it to a Nissan dealer, and paid for a transmission inspection, and they said it was totally fine, even though I regularly experienced it failing to shift (or slide, I guess) between gears while accelerating. Around 90k miles it stopped switching out of 1st gear while I was 400 miles from home. I brought it to a family friend mechanic, who showed me that the transmission fluid plug was covered in metal shavings.
CVTs, at least from Nissan are a black box. You can change the fluid, you can hook it up to a computer, but that's about it. There's no fixing them. When it's done you have to replace the entire transmission. I limped the car another 50 miles to a dealer and traded it in for a Chevy Cruze. I looked it up, and I was the only year model not to have a class action yet. Later there was, and I think they settled for a 500 dollar voucher towards a new Nissan. No thanks.
