• Electrical#2019424August 22, 2019

  195 units affected

  Issue: On certain vehicles equipped with a 6-cylinder gasoline engine, the wiring to the engine coolant pump could contact and become damaged by the engine fan. If this occurs, it could cause the engine coolant pump to stop working and the engine to overheat and stall. This could also cause the 48V on-board electrical system to deactivate while the engine is running. Under this condition the vehicle could be continued to be driven, however, the engine could not be restarted after it is switched off by the ECO start/stop function or the glide mode. Safety Risk: A loss of engine power and/or a loss of power to electrical systems could increase the risk of a crash. Corrective Actions: Mercedes-Benz will notify owners by mail. Owners will be instructed to take their vehicle to a dealer to inspect, and if necessary, replace the wiring to the coolant pump. Dealers will also re-route the wiring to prevent contact with the engine fan.

• Brakes#2019357July 23, 2019

  755 units affected

  Issue: On certain vehicles equipped with the Driver Assistance Package, a software problem may cause the Active Brake Assist feature not to work properly. This could affect the feature’s ability to help reduce or avoid a crash. While the system will still provide audible and visual warnings, the autonomous braking might not occur. Safety Risk: If the brake assist system does not function properly, there could be an increased risk of a crash. Corrective Actions: Mercedes-Benz will notify owners by mail and instruct them to take their vehicle to a dealer to update the radar sensor control unit software.

• Lights And Instruments#2018727December 20, 2018

  126 units affected

  Certain vehicles may not comply with the requirements of Canada Motor Vehicle Safety Standard (CMVSS) 108 - Lighting System and Retroreflective Devices. Vehicles may have been assembled with headlamps that allow for horizontal adjustment, which is contrary to the requirements of the standard. This could reduce vehicle visibility, or could adversely affect the vision of oncoming drivers during low-light and night-time conditions, which could increase the risk of a crash causing injury and/or damage to property. Correction: Dealers will install sealing caps on the headlamps to seal the adjustment screws.
