Consumer Description

There were numerous Engine Oil Leak Recalls by Mercedes-Benz. There was a recent recalls announced in 2023, however, my vehicle 2014 GL450 with now about 50K miles, was not included in the list. Since there have been engine oil leaks problem reported and recalls, I'd like to report my car engine oil leaks problem too. It seems that the engine oil leaks problem is a "design" issue and across many car models and years made by Mercedes-Benz. With that said, it make safety sense to have the recalls extended to those cars with engine oil leaks problem reported. Below is information from dealer diagnostic report on engine oil leaks problem, "Valve Cover Re-seal: FRONT TIMING COVERS RECOMMENDED RESEAL SIPING OIL BOTH SIDES Item Description During a vale cover reseal, the valve cover is scraped and cleaned of any old residue, before a layer of silicone sealant is applied to the cover and then reattached to the head of the engine. Reason If not resealed or replaced, the valve cover will leak oil resulting in a burning smell coming from the vehicle’s engine. A loss of oil over time can result in harmful damage of the engine's internal components."
