Transport Canada lists: C 2014–2020 · Cla 2014–2020 · Gla 2014–2020 · GLC 2014–2020

What is wrong

Why it matters

A panel that detaches from a moving vehicle could create a road hazard for others and 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 replace the front roof panel.

16 August 2021

Transport Canada lists: C 2010–2017 · E 2010–2017

What is wrong

Why it matters

An airbag that does not inflate properly can increase the risk of injury in a crash.

What the dealer will do

Mercedes-Benz will notify owners by mail and instruct you to bring your vehicle to a dealer to replace the passenger-front airbag.

Seats And Restraints

Transport Canada recall 2021045 · manufacturer campaign 9190309

3 February 2021

Transport Canada lists: C 2017–2020

What is wrong

On certain C-Class cabriolet models equipped with the PRE-SAFE system, the front seat belts may not retract completely to their storage position. Canadian regulations require seat belts to retract fully when not in use.

Why it matters

If the seat belt does not fully retract, the occupant may find the operation of the seat belt inconvenient and not wear it. This could increase the risk of injury in 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 function of the front seat belt retractors and adjust the dampening foam, if necessary.

Transport Canada recall 2019091

26 February 2019

Transport Canada lists: C 2017–2018 · E 2017–2018

What is wrong

On certain coupe and cabriolet models, the front seatbacks may not fully lock on the right side. In a crash, a seatback that is not properly locked could allow unsecured objects from the rear seats to move forward.

Why it matters

A seatback that is not properly locked could increase the risk of injury in a crash.

What the dealer will do

The company will notify owners by mail. Owners will be instructed to take their vehicle to a dealer to inspect front seatbacks and replace them as necessary. Note: This is an expansion of Recall 2018-161.

Transport Canada lists: C 2011–2017 · CLS 2011–2017 · E 2011–2017 · GLC 2011–2017 · and 4 more

What is wrong

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.

What the dealer will do

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.

9 July 2018

Transport Canada lists: C 2017–2018

What is wrong

On certain cabriolet models, the rear beltline body trim could separate from the vehicle. If this occurs while the vehicle is in motion, it could create a potential road hazard that could increase the risk of injury for other road users or bystanders.

What the dealer will do

Dealers will check the rear beltline trim and replace it, if necessary.

Airbag

Transport Canada recall 2017557

15 November 2017

Transport Canada lists: C 2017

What is wrong

Certain vehicles may not comply with Canada Motor Vehicle Safety Standard 208 - Occupant Protection in Frontal Impacts. The airbag control module may have been programmed with incorrect software. This could affect how the passenger airbag and seat belt force limiter are deployed in a crash, affecting compliance to the standard and increasing the risk of injury and/or damage to property.

What the dealer will do

Dealers will reprogram the airbag module. Note: This recall affects C-Class coupe models only.

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.

Transport Canada recall 2017205

11 April 2017

Transport Canada lists: C 2017 · GLC 2017 · S 2017

What is wrong

Certain vehicles may have been equipped with front seat belt pretensioner igniters that do not meet specifications. This could cause the affected pretentioners to fail to deploy properly in the event of a crash (where deployment is warranted), which could increase the risk of injury to vehicle occupants.

What the dealer will do

Dealers will replace the affected front seat belt pretentioners.

Engine

Transport Canada recall 2017062

Transport Canada lists: B 2015–2017 · C 2015–2017 · Cla 2015–2017 · E 2015–2017 · and 2 more

What is wrong

On certain vehicles, the starting current limiter could be overloaded under certain conditions. In the event the starter is blocked, a very high electric current could flow through the starting current limiter during repeated engine starting attempts. The high electric draw could cause the starting current limiter to overheat causing the surrounding components to melt which would increase the risk of fire causing injury and/or damage to property.

What the dealer will do

Dealers will install an additional fuse in the electrical line to the starter.

Transport Canada lists: C 2017–2018 · E 2017–2018

What is wrong

On certain vehicles, the seatbacks of the front seats may not fully lock on the right-hand side of the respective seat.

What the dealer will do
