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.
Accessory all season floor mats purchased and installed may restrict accelerator pedal operation, resulting in a sticking pedal. Dealers will replace the floor mats free of charge to resolve the concern.
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.
The rear leaf springs may not have been manufactured correctly. As a result, the spring may crack and fail at the mounting eye. A failed leaf spring would increase the risk of a crash. Dealers will replace the rear springs as necessary free of charge to correct this concern.
