• Recall R/2017/124 [UK]: Faulty control unit may cause vehicle to perform outside specification
  Where a control unit coding was updated in a workshop between 3 december 2016 and 5 december 2016 the coding may not correspond to the specification and may trigger unplanned action in the vehicle. The safety and emissions systems may not react as design intent.
  recall the vehicles that are likely to be affected and update the software in the corresponding control units.

• Recall R/2017/282 [UK]: Electrical wiring in steering assembly may be insufficiently grounded
  The steering column clock spring may break. This will cause warning messages to illuminate in the instrument cluster but in extreme instances it may cause the driver's airbag to deploy.
  affected vehicles will be recalled to establish sufficient grounding of the steering components.

• Recall R/2018/098 [UK]: Steering components may be insufficiently grounded
  It has been determined that the steering airbag electrical components are insufficiently grounded. Failure of the steering column module clock spring could result in an inadvertent deployment of the driver airbag which may cause risk of injury to the driver and an increased risk of a potential collision.
  on affected vehicles the manufacturer will fit a contact bridge to the outer race of the steering column top bearing which will provide correct grounding.

• Recall 2021514 [Canada]: Airbag
  Issue: on certain vehicles, an incorrect passenger-front airbag may have been installed during a previous repair. As a result, the airbag may not inflate properly in a crash. Safety risk: an airbag that does not inflate properly can increase the risk of injury in a crash. Corrective action: mercedes-benz will notify owners by mail and instruct you to bring your vehicle to a dealer to replace the passenger-front airbag.

• Recall 2018741 [Canada]: Airbag
  On certain vehicles, long-term exposure to high absolute humidity and temperature, combined with high temperature cycling, could eventually degrade the propellant contained in the passenger frontal airbag. This could cause the airbag to deploy with more force than normal. As a result, if the vehicle were involved in a collision that warrants airbag deployment, fragments could be propelled toward vehicle occupants, and the airbag assembly could be damaged, preventing proper function. These issues could increase the risk of injury. Correction: dealers will replace the passenger frontal airbag module. Note: canadian climate results in the propellant degrading slowly. The recall is being conducted as a precaution to address future risk, and is expected to replace airbag inflators before their function would be affected.

• Recall 2018724 [Canada]: Steering
  On certain vehicles originally sold or currently registered in areas of heavy road salt usage during winter months (quebec, new brunswick, nova scotia, prince edward island, and newfoundland & labrador), the bolts that attach the electric power steering assist motor to the steering gear housing may corrode and break. This could cause a loss of power steering assist. The resulting increase in steering effort could create the risk of a crash causing injury and/or damage to property. Correction: dealers will replace the mounting bolts and apply a corrosion protection coating to the gear housing and bolts. If the bolts bolt cannot be removed, a replacement steering gear will be installed.

• Recall 2017490 [Canada]: Airbag
  On certain vehicles, electrostatic discharge, when combined with a broken clock spring and insufficient grounding of the steering components, could lead to an inadvertent deployment of the driver's frontal airbag. Unintended airbag deployment, in a non-warranted (non-impact) situation, could startle the driver, which could result in a crash causing injury and/or property damage. In some instances, inadvertent deployment could cause minor injuries to vehicle occupants. Correction: dealers will add sufficient grounding to the steering components. Note: a broken clock spring would result in a driver airbag warning message appearing in the instrument cluster, as well as a red airbag warning lamp illuminating.

• Recall 2017145 [Canada]: Airbag
  On certain vehicles, an update provided between de 3rd and 5th of december 2016 to the vehicle control unit may have been incorrectly applied. This could affect the proper function of various safety systems such as airbag deployment sequence, seatbelts recognition status, speed limiter setting and others. These conditions could increase the risk of injury to the occupants in the event of a crash. Correction: dealers will update the affected control units.

• Recall 2012213 [Canada]: Lights and instruments
  Certain c63 amg coupe vehicles fail to conform to canada motor vehicle safety standard 108 – lighting system and retroreflective devices. These vehicles were inadvertently programmed with incorrect calibration software during vehicle assembly. As a result, the daytime running lamp (drl) system was not activated. A lack of drl illumination could render the vehicle less visible to other motorists and to pedestrians during daylight hours, possibly resulting in a crash causing property damage and/or personal injury. Correction: dealers will reprogram the body control module.
