Advanced corrosion could weaken the screws, leading to potential breakage during manoeuvring or parking. If all fixing screws fail, the power-assisted steering could detach, resulting in a loss of power steering and an increased risk of an accident.

If a gas generator ruptures, the airbag would then have no restraining function and loose parts from the gas generator could reach the vehicle interior. This would increase the risk of injury for passengers.

EU Safety GateThe steering column is not sufficiently earthed.As a result, in the event of an electrostatic discharge, the driver's airbag may be triggered when not required. This could cause an accident.
Measures: Type of economic operator taking notified measure(s): Manufacturer; Category of measure(s): Recall of the product from end users; Date of entry into force: Unknown
EU Safety GateThe steering coupling might not have been screwed to the correct torque specification.As a consequence, the steering coupling can become detached from the steering wheel axle and it would become impossible to steer the vehicle.

My concern is the repeated failure of the front wheel speed sensors rendering the ABS system and Traction Control System inoperable. The Speed Sensors failed as follows: 1.) 2015 at 9,474 Miles 2.) 2020 at 26,293 Miles 3.) 2022 at 30,281 Miles The vehicle has extremely low miles for the repeated failures to have occurred. If you research various Mercedes Benz Blogs online, you will see a trend of repeated speed sensors failures in all models of Mercedes cars & Mercedes Vans.
