NHTSA Complaint #11056762 — 2012 MERCEDES-BENZ C250

WHEN STARTING UP THE VEHICLE MAKE A TERRIBLE NOISE THAT LAST FOR 3-4 SECONDS BEFORE IT GOES AWAY. THE VEHICLE WAS VERIFIED BY A MERCEDES TECHNICIAN AND THE DIAGNOSTICS CAME BACK STATING AN ISSUE WITH THE "CAMSHAFT ADJUSTERS (INTERNAL FAULT)". I WAS TOLD THIS CONDITION WILL GET WORSE AND FINALLY ENGINE WILL STALL AND MAJOR DAMAGES WILL HAPPEN. WORST SCENARIO COULD PRODUCE BENT VALVES AND WILL REQUIRE A MAJOR ENGINE OVERHAUL WITH JUST 48,304 MILES ON IT. APPARENTLY, C250S ARE HAVING THIS ISSUE AND CUSTOMER ARE PAYING THE CONSEQUENCES FOR A DEFECTIVE PRODUCT. BY THE WAY, ENGINE HAS BEEN PERFECTLY MAINTAINED WITH MOBIL 1 (OW-40) AND ORIGINAL FILTER EVERY 5,000 MILES INSTEAD OF THE 10,000 MILES INTERVAL RECOMMENDED BY THE MANUFACTURER. THIS CONDITION COULD LEAD TO A MAJOR FAILURE WHILE DRIVING THE VEHICLE THAT COULD END UP INTO AN ACCIDENT.
