Certain vehicles were assembled with a right side window curtain airbag that was stitched together improperly. In the event of a crash, this airbag may deflate more quickly than intended, reducing the protection it may provide to vehicle occupants. Mercedes-Benz dealers will replace the right side window curtain air bag on affected vehicles to correct this concern.
These vehicles are equipped with a new type of A/C refrigerant - R1234yf. Testing has determined that escaping R1234yf refrigerant may ignite under specific conditions. A severe frontal crash may rupture one of the air conditioner refrigerant lines, which can result in a gaseous mixture of refrigerant being released into the engine compartment. The resulting fire could spread to additional combustible materials. Dealers will replace the R1234yf refrigerant with R134a (which is the type that had been used previously) along with new refrigerant lines (hoses) designed specifically for R134a.
Mercedes-Benz is recalling certain model year 2011 G550 and G55 (AMG) vehicles manufactured from September 20, 2010, through April 27, 2011. If the front passenger airbag were to deploy, parts of its molding strip could become loose and become a projectile in the passenger compartment. This projectile would increase the risk of personal injury during airbag deployment. Dealers will reinforce the connection between the molding strip and airbag cover flap to correct this concern.
On certain station wagon models, a connecting rod for the load leveling rear suspension system may fail. This could result in reduced vehicle control, increasing the risk of a crash. Dealers will inspect and replace the level control connecting rod as necessary to correct this concern.
The Diesel fuel filter may leak from the area around the heating component. Fuel may leak onto the roadway, increasing the risk of a crash. A fuel leak always increases the risk of a fire. Dealers will replace the Diesel fuel filter to correct this concern.
It has been determined that, under certain circumstances, use of the brake pedal may not disengage the cruise control as expected. All other means of disengaging the cruise control should remain effective. If the driver were to "pump" the brake pedal instead of applying consistent force, the level of force necessary to disengage the cruise control may be unusually high. Dealers will perform the repairs necessary to correct this concern. The recall is expected to begin September of 2011.
Forty-one vehicles may have a front engine pulley that was manufactured with an insufficient adhesive where the inner mass damper ring attaches to the vibration damper. If the inner ring were to separate with the hood open and the engine running, personal injury could result. Dealers will inspect and replace the affected parts to correct this issue. This recall is expected to begin during April of 2011.
Mercedes Benz is recalling 2010 C-Class, model 204; E-Class, model 212; and 2010–2011 E-Class Coupe/Cabriolet, model 207 vehicles due to a loss of power steering fluid that could result in power steering system failure. Owners may not have sufficient control of the vehicle in areas like parking lots, thus increasing the chance of a crash. Dealers will check and re-torque the connection fitting, free of charge.
The o-ring at the fuel filter area may leak Diesel fuel. Dealers will replace the fuel filters free of charge to resolve the problem.
Mercedes-Benz is recalling 2009 550 G-Class models due to fuel line quick connectors that were not properly connected on the assembly line. In case of a frontal crash, the fuel pump may no longer function, which could lead to fuel loss. In the presence of an ignition source, a fuel leak can result in a fire. Dealers will check the connectors and install a new clamp free of charge.
