Why is this still so controversial? Fluids in any vehicle should be changed at some point.

It’s required in other countries, and the CVT is a weak spot for long-term reliability.

Agreed, it’s surprising this isn’t standard in North America. I know several mechanics who are confused about why this isn’t recommended here.

It’s all about EPA ratings. If CVT fluid needs to be replaced every xx thousand miles, it counts toward the vehicle’s ‘lifetime’ emissions, affecting EPA scores.
