Reliability
4.5/5

2 known faults

500e 95 ch (24 kWh)

  1. 12 V battery discharging (car no longer starts)

    Severity 1/3 · Annoying

    Several sources report rapid discharges of the 500e's 12 V battery, often linked to electronic modules waking up: the car may then fail to start or unlock. Owners cite a software update carried out as a recall that solved the problem, or a faulty component (Uconnect unit battery, 12 V monitoring sensor). Remedies mentioned: updating the body control module, or a replacement AGM battery.

    Versions
    500e 95 ch (24 kWh), 500e 118 ch (42 kWh)

  2. Electronic and software bugs (error messages, disabled systems)

    Severity 1/3 · Annoying

    Owners report intermittent error messages, disabled functions and problems with the Uconnect multimedia system; these are usually dealt with by software updates at dealerships, though they do not always disappear (resets reported to have no effect). A review on Fiches-auto describes a car immobilised at 18,000 km despite several updates. Carverif notes the electrical systems as the car's weak point.
