2 known faults

TCe 90

  1. Weak 12 V battery and electronic glitches

    Severity 1/3 · Annoying

    A sensitive point according to owners: rapid discharges of the 12 V battery, charging messages, then warning lights and functions that malfunction when the voltage drops (unstable multimedia, black screen). Some owners find the glitches disappear after the battery is replaced or the control unit is updated. Owner accounts only, with no frequency statistics.

    Versions

  2. Rear windows working intermittently

    Severity 1/3 · Annoying

    Several owners report rear windows that work intermittently or not at all, sometimes despite replacement of the electronic module. A weak battery is often cited at the same time.

Read fault codes

An OBD scanner plugged in under the steering wheel shows stored fault codes, even with warning lights off: useful during the test drive.
