Overall
Sentiment is mixed and heavily dependent on powertrain and maintenance history. The vehicle is praised for its practical interior space, comfortable seating, and charming design, with some owners reporting reliable service over high mileage. However, significant and recurrent criticisms focus on major mechanical failures, particularly concerning the automatic transmission and engine, as well as expensive and complex repairs for issues like air conditioning.

Insufficient owner data available to identify a consensus "best" trim or model year. Feedback is centered on powertrain choice rather than trim levels.

Overall
Mixed to negative sentiment overall, heavily dependent on model year and powertrain. The vehicle is praised by a subset of owners for its unique, quirky styling, surprisingly spacious interior for its compact footprint, good headroom, decent fuel economy (reports of 30-34 MPG with the 1.4L turbo), and genuine off-road capability in Trailhawk trim. It is frequently described as a fun, characterful vehicle that is easy to park and capable in winter conditions with proper tires.
Best version to buy
Trailhawk trim is frequently mentioned for maximizing off-road capability with features like increased ground clearance, skid plates, and a locking rear differential. For later model years (post-2019), the 1.3L turbo engine is strongly recommended over the older 2.4L naturally aspirated engine.
