   Issue: On certain vehicles, water could leak into the rear of the vehicle and build up in the spare tire wheel well. If this happens, the fuel pump control unit could short circuit and cause the engine to stall. Note: This problem could cause a check engine light to turn on, a damp carpet in the cargo area and/or the sound of water moving in the spare wheel well while driving. Safety Risk: A sudden loss of power to the wheels could increase the risk of a crash. Corrective Actions: Mercedes-Benz will notify owners by mail and instruct you to take your vehicle to a dealership to inspect for water leaks and install a drain plug in the spare wheel well. The fuel pump control unit will be replaced, if necessary. To reduce the safety risk, you should regularly check for moisture in the cargo area and spare wheel well.

   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.

   On certain vehicles equipped with the Active Curve System (ACS), the oil in the ACS’s reservoir could start foaming under certain dynamic driving situations in combination with an oil level below minimum. The oil foam could leak out of the oil reservoir through the vent holes in the sealing cap and spray onto hot surface components of the exhaust system. This could increase the risk of fire causing injury and/or damage to property. Correction: Dealers will inspect the ACS reservoir for proper oil level and replace the sealing cap with an updated part.

   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.

   On certain vehicles, the axle bolts on the front and/or rear axle may not have been correctly assembled. This could cause the bolts to fracture, which could affect vehicle handling and stability, increasing the risk of a crash causing injury and/or damage to property.

   On certain vehicles, the fastener that attaches the rear seat belt might have been improperly assembled. If this condition were present, in the event of a vehicle crash with high loads on the belt attachment, the seat belt end fitting could separate and fail to properly restrain the occupant. This would increase the risk of injury. Correction: Dealers will inspect the seat belt fastener and repair if necessary.
