Reliability
4.5/5

2 known faults

i-MiEV 16 kWh

  1. Brake servo vacuum pump

    Manufacturer recall

    The vacuum pump that powers the brake servo has been the subject of several recall campaigns covering the i-MiEV, iOn and C-Zero trio. If it fails, the brake assistance is lost and stopping distances increase. In France, a letter from October 2020 warned of a pump that may not conform; in the United States, water could enter the pump and corrode it (2020 recall). Have the VIN checked with the dealer network.

    Fixed free of charge by a dealer and not counted in the reliability score: ask for proof the work was done (invoice, or a VIN check at a dealer).

  2. Battery: faulty cell and loss of range

    Severity 2/3 · Costly

    On the C-Zero twin, battery failures have been documented, in one case requiring the replacement of a faulty cell (cell transplant). Citroën put the cost of replacing the complete pack at 13,000 euros excluding VAT, excluding labour, for a C-Zero, with no pack in stock. A thorough diagnosis is worthwhile: in another case the fault was in the contactor rather than the battery.
