Not representative, but my mom has had two CVT Audis across at least 10-12 years now, maybe more, and not so much as a hiccup. She follows the schedule in the owners manual and the local dealership does the work.
Attitudes and assumptions towards car maintenance are lagging far behind the industry/technology.
