Early Nissan CVT had problems. Don't know about more recent. That's probably what the GP post was referring to?

Looks like CVT introdueced in 2014 for the Pathfinder. So if you're buying newer than that, you're getting one.

I'd advise you to do research on Nissan reliability before buying. Maybe something as simple as joining cr.org
