The recall only affects 2014 S550 models manufactured from April 11, 2013 through October 14, 2013. There are believed to be 290 cars affected by the recall in the U.S.
According to the automaker, the front seat belt anchors in the affected cars may not have been installed correctly, allowing them to come loose in a crash. If the seat belt anchor were to come loose, in the event of a crash, a passenger wearing the belt may not be properly secured, increasing the risk of injury.
Mercedes is in the process of notifying the owners of the affected cars. Dealerships will inspect and correct the front seat belt anchor fitting, as necessary, free of charge.
