NHTSA Complaint #11104245 — 2014 MERCEDES-BENZ GL550

DAIMLER AG, (DAG) THE MANUFACTURER OF MERCEDES-BENZ VEHICLES, HAS DETERMINED THAT ON CERTAIN GLE, GLS AND GLE COUP VEHICLES (166, 292 PLATFORM) WITH THE ACTIVE CURVE SYSTEM (ACS), THE OIL IN THE ACS'S OIL RESERVOIR COULD START FOAMING UNDER DYNAMIC DRIVING SITUATIONS IN COMBINATION WITH AN OIL LEVEL BELOW MINIMUM. THE OIL FOAM MIGHT LEAK OUT OF THE OIL RESERVOIR THROUGH THE VENT HOLES IN THE SEALING CAP. DEPENDING ON THE ORIENTATION OF THE VENT HOLES IN THE SEALING CAP, LEAKING OIL COULD SPRAY ONTO HOT SURFACE COMPONENTS OF THE EXHAUST SYSTEM. IN SUCH A CASE THE RISK OF A FIRE CANNOT BE RULED OUT. AS A PRECAUTIONARY MEASURE AN AUTHORIZED MERCEDES-BENZ DEALERSHIP, WILL CORRECT THE OIL LEVEL IF NECESSARY AND REPLACE THE SEALING CAP OF THE OIL RESERVOIR WITH AN OPTIMIZED SEALING CAP TO PREVENT OIL FOAM LEAKAGE. SAFETY RISK: DEPENDING ON THE ORIENTATION OF THE VENT HOLES IN THE SEALING CAP, LEAKING OIL COULD SPRAY ONTO HOT SURFACE COMPONENTS OF THE EXHAUST SYSTEM. IN SUCH A CASE THE RISK OF A FIRE CANNOT BE RULED OUT.
