Well, they're addressing all the issues, even if it means recalling almost all the Ascents in the early years.
That's something ZF-9 transmission owners aren't getting. Instead, Honda, Acura and the likes switched to a new transmission for the new model year and aren't addressing the issues with the ZF-9HF. I'd rather a company that goes through the effort than pretend (a few of the ZF-9HF using companies, who did a
recall for "programming" that didn't really fix the issue) or do nothing (all of them after the initial "recall").
Here's the full list: Acura TLX, Acura MDX, Chrysler 200, Chrysler Pacifica (2017– gas versions only), Fiat Doblò, Fiat 500X, Honda Pilot, Honda Odyssey, Honda Passport, Honda Civic (201

, Honda CR-V (diesel 2015-) Jeep Cherokee (KL), Jeep Renegade, Ram ProMaster City, Range Rover Evoque, Land Rover Discovery Sport, Jaguar E-Pace.
Most importantly though, you need to do what makes you feel comfortable, and drive what you enjoy driving. Wishing you much enjoyment in your new Highlander!!!
