NHTSA Complaint #10327627 — 2004 MERCEDES BENZ C230

THE CAM SENSORS ON THE MERCEDES M271 ENGINE LEAK OIL WHICH SPREADS TO OTHER COMPONENTS VIA THE WIRE HARNESSES CONNECTED TO CAM SENSORS. OIL CONTAMINATION WILL DAMAGE OTHER ELECTRICAL COMPONENTS (NAMELY THE ECU AND EXHAUST OXYGEN SENSORS) IF THE CAM SENSORS AND WIRE HARNESSES ARE NOT REPLACED. A NEW CAM SENSOR AND WIRE HARNESS HAS BEEN DESIGNED AS THE CORRECTIVE ACTION. THE DEFECTIVE CAM SENSOR AND WIRE HARNESS WERE USED ON THE PREVIOUS ENGINE DESIGN (M111). THERE IS A TECHNICAL SERVICE BULLETIN FOR M111 ENGINE BUT NOT THE M271 ENGINE. MERCEDES REFUSES TO RECALL THIS DEFECTIVE DESIGN ON THE M271 ENGINE CAUSING OWNERS TO PAY FOR THE $900 PREVENTATIVE MAINTENANCE. WITHOUT THIS REPAIR THE ECU (PART COST $2000) AND OXYGEN SENSORS (QTY 2 @ $250 EA) WILL BE EVENTUALLY DAMAGED AND WILL NEED TO BE REMOVED AND REPLACED. *TR
