Coolant was found mixing with engine oil (milky oil), indicating internal engine failure (I was informed it could be oil cooler/housing, thermostat, head gasket, or related components). Vehicle is currently at an authorized Mercedes-Benz dealership and available for inspection. The front left inner lining of my front break pad also \"failed\" inspection and the other 3 front break pads say \"caution\" and I never received a notification or warning about my breaks. Safety Risk: Coolant contamination of engine oil can cause sudden engine failure or loss of power without warning, creating a serious safety risk while driving, especially at highway speeds. There was no indication that engine oil was mixing with coolant, check engine light failed to illuminate/ no diagnostic warning illuminated. The condition was discovered incidentally during routine maintenance, which prevented any opportunity for corrective action prior to the failure. Confirmation: The condition was confirmed by an authorized Mercedes-Benz dealership during routine maintenance. The dealership stated the failure was not caused by owner misuse.Inspection: Vehicle has been inspected by an authorized Mercedes-Benz dealership (manufacturer representative). No police or insurance inspection occurred, as there was no accident or external event. Warnings/Symptoms: No check engine light or diagnostic warning ever illuminated. The issue was discovered incidentally after I received a low battery voltage notification and a routine maintenance reminder indicating service was due in approximately 1,000 miles, which I arranged promptly. The manufacturer will not perform full diagnostic teardown to determine the root cause unless I pay approximately $3,000 out of pocket.
