Mercedes-Benz C300 recalls
Risk: A detached roof panel can become a road hazard, increasing the risk of a crash.
Risk: Various system failures, such as loss of drive power, reduced exterior lighting, or loss of dynamic control functions including stability and traction control, can increase the risk of a crash.
Risk: A fuel leak in the presence of an ignition source, such as hot engine or exhaust components, can increase the risk of a fire.
Risk: The adhesive bonding of the front panel might deteriorate, possibly causing the front panel to detach from the vehicle and become a road hazard, increasing the risk of a crash.
Risk: Failure of the eCall system may result in emergency responders being dispatched to the wrong location, increasing the risk of injury following a crash.
Risk: An incorrect passenger air bag may not provide adequate protection, increasing the risk of injury in the event of a crash.
Risk: An inaccurate vehicle location may delay emergency responders, increasing the risk of injury.
Risk: An inflator explosion may result in sharp metal fragments striking the passenger or other occupants resulting in serious injury or death.
Risk: A car that cannot be properly steered has an increased risk of a crash.
Risk: An inflator explosion may result in sharp metal fragments striking the driver or other occupants resulting in serious injury or death.
Risk: If the driver air bag inadvertently deploys, it can increase the risk of injury and a crash.
Risk: A loss of steering can increase the risk of a crash.
Risk: A loss of electrical contact will cause the electric power steering assist to deactivate, increasing the risk of a crash.
Risk: If the air bags do not deploy as intended in the event of a crash, there would be an increased risk of injury in the event of a crash.
Risk: If the starting current limiter overheats, the surrounding components can melt, increasing the risk of a fire.
Risk: An inflator rupture may result in metal fragments striking the vehicle occupants resulting in serious injury or death.
Risk: A damaged ESP control unit may inadvertently activate the stability control altering the vehicle's path. Additionally, the electronic parking brake may not function. Either condition may increase the risk of a crash.
Risk: If the vehicle experiences a loss of power steering assist, extra steering effort will be required at lower speeds, increasing the risk of a vehicle crash.

Risk: The malfunctioning air bag control unit may cause the air bags to unexpectedly deploy increasing the risk of injury and the possibility of a vehicle crash. Alternatively, the air bag control unit malfunction may cause the air bags to not deploy in the event of a crash necessitating air bag deployment, increasing the risk of occupant injury.
Risk: If the locking plate is not properly secured to the fuel delivery module it may become loose, and leak fuel, increasing the risk of a fire. If the electrical wires are pinched, the fuel pump may stop working, resulting in a stall, thereby increasing the risk of a crash.
