Nissan has had some CVT failures, but not an alarming number, and nowhere as many as the infamous Honda V6 5-speed automatics from the 2000-2003 era.
Most of the issues were with the Muranos, and a number of the CVT failures were not due to the CVT itself, but rather due to the transfer case failing which caused the CVT to failure eventually due to leaks.
I was bashing based on my years back in the hybrid car research (late 90s) and the belt based CVT Jatco (Nissan) transmission. It is fundamentally fragile as soon as it slipped, and it is very picky about the pulley pressure that drives the belt.
It works fine in a constant torque environment. If you put any shock load on it, it won't handle it well like a gear based transmission. Transfer case issue on a gear based transmission will not be that big of a deal as long as the gear can mesh together. On a belt/pulley based CVT, a crack in the transfer case means the pressure isn't the same anymore, and then the belt slip, and then the failure.
BTW, Honda V6 auto transmissions are junk too, not just Nissan.
