   Issue: On certain vehicles, the plastic panel located between the windshield and the panoramic sunroof may not have been attached correctly during a prior service repair. Over time, the panel could loosen and separate from the vehicle. Note: This is an expansion of Transport Canada recall 2021-170. Safety Risk: A panel that detaches from a moving vehicle could create a road hazard for others and increase the risk of a crash. Corrective Actions: Mercedes-Benz will notify owners by mail and advise you to take your vehicle to a dealership to replace the front roof panel.

   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.

   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, 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.
