    Reported June 14, 2017Model years 2015–2017DVSA recall R/2017/15712,920 vehicles affected

    Faulty stability control software may leave residual hydraulic pressure, causing the brakes to apply and heat up. This could further increase brake heat, affect the fluid and cause a fire in the wheel housing. The software will be updated.

    Official DVSA recall text
    Component
    BRAKES MAY OVERHEAT CREATING A RISK OF SMOKE AND/OR FIRE
    Defect
    The software for the Electronic Stability Program (ESP) is faulty. The fault could lead to a low residual pressure in the hydraulic system so the brakes are applied and gain heat. This increased heat will apply the brakes further and could adversely affect the brake fluid. Fire in the wheel housing cannot be ruled out.
    Remedy
    Recall the vehicles that are likely to be affected and update the software for the ESP.

  8. Stability control software may keep brakes applied
