Daimler AG's Mercedes-Benz unit is issuing its second recall in the last two year to address leaking fuel filters in diesel vehicles.

The company said in documents posted on the National Highway Traffic Safety Administration that it is recalling 6,872 vehicles, according to The Detroit News.

The new recall includes diesel versions of the 2011 E-Class, 2012 S-Class, 2011 R-Class, 2011 ML-Class and 2011 GL-Class.

The diesel fuel filter has an a seal that can leak around the heating component.

In October, Daimler recalled 2,297 2011 diesel vehicles for the same problem. Daimler made a change in the production process in June after it received a number of field reports in Europe of leaking fuel.

But after the recall, Daimler continued to receive a number of further complaints - and made another production change.

The recall will begin next month and dealers will replace the diesel fuel filter if necessary. The company estimates less than 1 percent of recalled vehicles will need to be fixed.
