Mercedes-Benz has issued a recall on certain versions of its latest 2013 GL Class SUV due to a potential fault with the affected vehicles’ seat belt anchor bolts.

The recall only affects 2013 GL350 BlueTEC, GL450 4MATIC, GL550 4MATIC, and GL63 AMG models built from May 15, 2012 through October 4, 2012.

According to the automaker, there are some 272 vehicles affected by the recall in the U.S. alone.

The reason for the recall is second row seat belt anchor bolts that may have been improperly torqued.

If the bolts are in fact improperly torque, the seat belt anchors may continue to loosen and in the event of a crash the belted occupant may not be properly restrained, increasing the risk of injury.

Mercedes-Benz is is in the process of notifying owners affected by the recall. They will be asked to take their vehicles to one of the automaker's dealerships, which will check and tighten the bolts if necessary, free of charge.
