Visual System

Transport Canada recall 2025399 · manufacturer campaign 5496538

30 July 2025

Transport Canada lists: B 2018–2019

What is wrong

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.

Why it matters

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.

What the dealer will do

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.

Transport Canada recall 2021507 · manufacturer campaign 4694203

11 August 2021

Transport Canada lists: B 2013–2020 · Cla 2013–2020 · Gla 2013–2020

What is wrong

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).

Why it matters

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.

What the dealer will do

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

7 April 2021

Transport Canada lists: B 2017–2020 · Cla 2017–2020 · Gla 2017–2020

What is wrong

On certain vehicles, the universal joint connection on the steering shaft could loosen over time. As a result, there could be noise or a change in steering feel. If a driver continues to operate the vehicle, the bearing could separate from the universal joint and cause a loss of steering control.

Why it matters

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

What the dealer will do

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.

What is wrong

On certain vehicles, a software problem could cause the rearview camera image not to appear on the central display. Canadian regulations require the rearview image to display when the transmission is shifted into reverse gear.

Why it matters

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.

What the dealer will do

Transport Canada lists: B 2012–2018 · C 2012–2018 · Cla 2012–2018 · E 2012–2018 · and 3 more

What is wrong

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.

What the dealer will do

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.
