WASHINGTON — Mercedes-Benz USA is expanding a December 2014 recall to include another 814 2015 Mercedes-Benz E250 Bluetec and E250 Bluetec 4Matic vehicles because an oil leak may increase the risk of a fire, according to the National Highway Traffic Safety Administration.
"In the affected vehicles, oil may leak from around the chain tensioner gasket area," said NHTSA in its recall summary. "Leaking oil may drip onto a hot engine surface, increasing the risk of a fire. Additionally, the leaking oil may be a road hazard for other vehicles, increasing the risk of a crash."
The automaker told federal safety regulators the engine might stall as a consequence of the defect.
The affected 2015 E250 Bluetec vehicles were built from November 3, 2014 to December 15, 2014. The affected 2015 E250 Bluetec 4Matic vehicles were built from November 4, 2014 to December 17, 2014.
A Mercedes-Benz spokeswoman did not respond immediately to a query from Edmunds asking if there are any fires, injuries, crashes or fatalities linked to the recall.
Mercedes-Benz dealers will replace the chain tensioner gasket. Owners are expected to be notified one or two weeks after the launch of the recall on June 19. Owners can contact Mercedes-Benz customer service at 1-800-367-6372.
Edmunds says: If you own one of these vehicles, plan on scheduling a service appointment with your dealer in July.
