Mercedes-Benz is recalling four high-tech diesel models from the company's 2014 and 2015 lineups. The recall is meant to repair a potential oil leak that could start a fire in the vehicles' engine compartment and make roads hazardous for other drivers.
The problem with these vehicles -- all of which belong to Mercedes-Benz's reduced-emissions BlueTec diesel family -- stems from a loose chain tensioner gasket. According to a letter from the National Highway Traffic Safety Administration (PDF), the seal on the gasket may permit oil to leak onto a vehicle's engine. Not only does that increase the risk of a fire, but if the oil drips onto the road, it can also make driving conditions hazardous for other vehicles. The fix involves a replacement of the gasket, which will be carried out free of charge.
The recall affects the following models:
- 2014-2015 E250 BlueTec
- 2014-2015 E250 BlueTec 4Matic
- 2014-2015 GLK250 4Matic BlueTec
- 2015 ML250 4Matic BlueTec
The recall is limited to vehicles manufactured between February 28, 2014 and November 10, 2014. Mercedes estimates that 4,871 vehicles registered in the U.S. are affected.
Mercedes-Benz says that it began mailing notifications to owners last week, so if your vehicle is included in the recall, you should've received something by now. If you haven't (or if you're worried that you threw it out in a fistful of holiday cards and junk mail), you should call Mercedes-Benz customer service at 800-367-6372 and ask about recall #2014120002. Or, if you prefer, you can contact NHSTA at 888-327-4236 and ask about safety campaign #14V762000.
