1 known fault

Seal U DM-i 218 ch (hybride rechargeable)

  1. Multimedia and driver assistance still need refining

    Severity 1/3 · Annoying

    L'argus' road test found a ventilation menu accessible only through the steering-wheel buttons with Android Auto, a speed alert that cannot be switched off, and a semi-autonomous assistant that is sometimes sluggish, with unwanted braking. Car Checker points to software maturity that is still limited, often corrected by a remote update or under warranty.
