I'm on my second Honda Fit. I can't say it it's the most exciting car to drive but both have had zero trouble with the CVT at 110,000+ miles. The first one died a violent death (totaled twice in a year) and the second is going strong. All the major systems performed flawlessly, though there were some struggles with the hatchback handle and the tire pressure monitoring system.

I do remember renting a Dodge Caliber year back when the CVT performed terribly going up hills as automatic but it wasn't bad at all if you used the paddle shifters. I did read reviews of people who bought the things, drove 20,000 miles and complained bitterly about performance and never figured out about the paddle shifters though.
