— Mercedes-Benz is recalling over 4,800 cars that can leak oil from a faulty gasket seal. Mercedes-Benz says the recalled cars include the 2014-2015 E250 BlueTec, E250 BlueTec 4Matic, GLK250 4Matic BlueTec and 2015 ML250 4Matic BlueTec.
Mercedes-Benz engineers found instances of chain tensioner leakage in cars located outside the U.S. Mercedes said the problem was traced to a chain tensioner not properly torqued in the engine block. Further investigation showed there were variations in the tolerances of the gasket material.
The gaskets can have a settling behavior that interferes with the pretensioning force, a problem that can cause a faulty gasket seal to leak engine oil. That leaking oil could trigger a fire if the oil contacts an ignition source, it can leave an oil slick on the road or cause the engine to die from a lack of oil.
Mercedes says the recalled cars were manufactured February 28, 2014, to November 10, 2014.
The recall is expected to begin December 26, 2014. Mercedes-Benz will notify owners and dealers will replace the chain tensioner gasket.
Owners of the 2014-2015 E250 BlueTec, E250 BlueTec 4Matic, GLK250 4Matic BlueTec, and 2015 ML250 4Matic BlueTec can contact Mercedes at 800-367-6372 and refer to recall number 2014120002.
