“I have been noticing an increasing small leak in engine oil on my garage floor. Recently I saw a very large puddle while parked at a lot and had the car taken to nearest dealer. Dealership advised replacing oil cooler and associated system parts. I believe if I had not noticed leak/puddle, engine may have seized while driving. Also, on many mb forums, the oil cooler is implicated as the culprit for a large oil leak.”
NHTSA complaint #10546126, filed 2013-09, 46,213 miles“After a long trip with the 2010 mercedes GL350 bluetec, I noticed fresh oil on the garage floor. I took the GL350 to a local mechanic for an oil change the day after, and the mechanic noted that there is significant oil under the engine. Few days after, check engine light came on, and I took the GL350 in for a check, and another mechanic confirmed that the engine oil cooler seal is broken causing the oil leak. It seems that this is a very common fault with mercedes om642 engine in my GL350.”
