What owners say

Mixed to positive sentiment overall, with a strong consensus that it is an excellent vehicle for its intended purpose.

  • Very frequentICCU (Integrated Charging Control Unit) failure

    Causes vehicle breakdowns and recurrent 12V battery drain. Replacement is covered under warranty but requires dealership service.

  • RecurrentReduced winter range

    Real-world highway range can drop significantly in cold temperatures, with one report of approximately 265 km (165 miles) from a rated 435 km (270 miles) in extreme cold (-20°C / -4°F).

  • RecurrentMissing convenience features

    Lack of Homelink/garage door opener, laminated glass for sound insulation, and a dedicated "dog mode" or easy climate-keep function are noted as omissions compared to competitors like Tesla.

  • RecurrentDealership service variability

    Service department quality is inconsistent; some are described as incompetent or difficult, while others are efficient. This impacts the repair experience for known issues like the ICCU.

  • IsolatedSoftware limitations

    Limited number of climate-control timers (only two), no location-based timers, and a cumbersome process to use utility mode as a substitute for dog mode.
