Locally, the Honda CVTs (on the 2003-2008 City / Jazz) are known to have problems with the start clutch after a few years. That said, ours has been fine so far, after 9 years and nearly 80,000 km.
That torque converter must take some load off that start clutch. Mitsu has already used this setup with the Lancer, I believe, though the Mirage is the first one to have a planetary gearset on it as well.
