The short answer

Overall
Sentiment is sharply divided by transmission type and generation. For models equipped with the manual transmission, owner feedback is overwhelmingly positive, describing them as reliable, fun to drive, economical, and a great value. This is particularly true for the final generation (2012-2018) with a manual gearbox.
Best version to buy
Manual Transmission Models (any trim, 2012-2018 generation): There is a very strong, repeated consensus that the manual transmission is the defining factor for a good ownership experience. The manual is described as "rock solid," "easy to drive," and the solution to avoiding the pervasive automatic transmission problems.
Known issues
Overall
Sentiment is polarized, with a strong divide between owners who cherish the vehicle's unique character and practicality and those who have faced significant mechanical failures. A dedicated group of owners expresses deep affection for the Cube's boxy design, excellent visibility, easy ingress/egress, surprising interior space, and utility as an economical urban commuter. Many report trouble-free ownership with high mileage (over 150,000 miles/241,000 km).
Best version to buy
Manual Transmission Models (any year): Unequivocally recommended over CVT-equipped models due to pervasive and severe reliability concerns with the automatic transmission. The 6-speed manual is specifically praised for making the car feel more responsive ("a blast") and for eliminating the primary failure point.
