Summary
Propeller Shaft Mercedes-Benz AG (“MBAG”), the manufacturer of Mercedes-Benz vans, has determined that on certain Metris vehicles from platform 447 (VS20), the propeller shaft may not be attached to the intermediate bearing according to the specification. If the propeller shaft is improperly attached to the intermediate bearing, over time damage to the propeller shaft joint could occur. The rotational imbalance of the shaft could lead to vibrations to the underbody of the vehicle, and to inaccurate signals to the airbag control unit. If improper signals are sent to the airbag control unit, the frontal airbags could inadvertently deploy, increasing the risk of injury to front occupants and increasing the risk of a crash.
