    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.

    Official DVSA recall text
    Component
    ELECTRICAL FAULT COULD ALLOW VEHICLE TO ROLL AWAY WHEN LEFT PARKED
    Defect
    On certain vehicles fitted with 9 speed transmission the back up battery may not connect during main battery failure. This may prevent selection of Park on the transmission or operation of the electronic parking brake.
    Remedy
    On affected vehicles adapt harness to manufacturer's specification and recode the system.

  24. Ignition switch backup power may be disconnected

    Reported April 13, 2016Model years 2016NHTSA campaign 16V211000223 vehicles affected

    If the main battery loses power while driving, a poorly connected backup supply may prevent shifting to Park or applying the electric parking brake. The vehicle may roll when the driver exits, increasing injury risk. Dealers will correct the wiring and update the software, free of charge.

    Official NHTSA recall text
    Component
    ELECTRICAL SYSTEM:WIRING
    Defect
    Mercedes-Benz USA, LLC (MBUSA) is recalling certain model year 2016 SLK300 vehicles manufactured June 2, 2015 to July 14, 2015 and equipped with a nine-speed automatic transmission. The backup power supply for the ignition switch in the affected vehicles may not have been properly connected. As a result, if the vehicle is being driven and there is a loss of power from the main vehicle battery, the transmission cannot be shifted to "Park" nor can the electric parking brake be applied.
    Consequence
    In this situation, without the backup power supply, the only way to keep the vehicle from moving is to press the brake pedal. As soon as the driver attempts to exit the vehicle, the vehicle may roll, increasing the risk of injury.
    Remedy
    MBUSA will notify owners, and dealers will correct the ignition switch wiring and perform a software update, free of charge. The recall began on May 9, 2016. Owners may contact MBUSA customer service at 1-800-367-6372.
