Visual System

Issue Description

On certain vehicles, a software problem could cause a small part of the rearview camera image to be blocked. Canadian regulations require the full rearview image to display while the transmission is in reverse gear.

Safety Risk

A rearview camera image that doesn't display properly could reduce a driver's ability to see behind the vehicle while backing up. This could increase the risk of a crash.

Corrective Action & Repair

Mercedes-Benz will notify owners by mail and advise you to take your vehicle to a dealership to inspect and, if necessary, update the rearview camera software.

Steering

Issue Description

On certain vehicles, the power steering control unit may corrode. If this happens, moisture could enter the control unit and cause it to fail. This could cause a loss of power steering assist. Note: This is an expansion of Mercedes-Benz recall 4694202 (Transport Canada Recall No. 2020-617). This recall only affects vehicles that were originally sold or ever registered in areas of heavy road salt usage (Ontario, Quebec, New Brunswick, Nova Scotia, Prince Edward Island, and Newfoundland & Labrador).

Safety Risk

A loss of power steering assist would result in a sudden increase in steering effort, especially at low vehicle speeds. This could increase the risk of a crash.

Corrective Action & Repair

Mercedes-Benz will notify owners by mail and instruct you to take your vehicle to a dealer to replace the power steering control unit.

Safety Risk

A loss of steering could create the risk of a crash.

Corrective Action & Repair

Mercedes-Benz will notify owners by mail and instruct you to take your vehicle to a dealer to inspect the steering shaft. It will be replaced, if necessary.

Safety Risk

A rearview camera image that does not display could reduce a driver's ability to see behind the vehicle while backing up. This could increase the risk of a crash.

Corrective Action & Repair

Airbag

Issue Description

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.

Safety Risk

A failure of this component (airbag) may increase the risk of a crash or injury.

Corrective Action & Repair

Authorized dealerships will inspect the vehicle and complete all necessary repairs free of charge (parts and labor).
