Actaully the really crappy CVT's were Subaru Justys and Honda's. Not sure who is making them besides Jatco which is a subsidiary (wholly owned) of Nissan. All are based on the Van Dorn belt drive of the 50s. It took belt technology and development to get them reliable. Nissan gave us a 10 year 120k warranty on our Murano, which was rated to tow 3500 pounds.
Modern CVTs are "push belts" with 400+ steel segments that push against each other instead of the traditional pull we think of in belts.
