2015 MERCEDES-BENZ C300 Complaints

THERE IS A FUEL HOSE (PARTS NUMBER: 274 070 3500) CONNECT TO THE HIGH PRESSURE PUMP IN FRONT ENGINE AREA. THE FUEL HOSE WAS FASTENED BY A CLAMP (NOT SURE THE PARTS NUMBER) . BECAUSE OF THE DESIGN FLAW, THIS CLAMP WILL LOOSE SINCE IT'S A SNAP JOINT ASSEMBLIES NOT TIGHTEN BY SCREWS. UNDER THIS SITUATION, THE FUEL HOSE WILL LOOSE AND AFFECTED BY THERMAL EXPANSION, THIS PROBLEM WILL CAUSE FUEL LEAK/SEEPING. WE CAN SMELL FUEL NEAR THE PUMP BEFORE WE START CAR IN COLD IN THE MORNING AND THIS SMELL CAN BE SMELLED UNTIL THE ENGINE WORKING INTO THE NORMAL OPERATING TEMPERATURE OR WHEN WE TURN ON THE AC OR HEATER . FUEL IS A VERY CRITICAL SAFETY PROBLEM AND USUALLY WE CANNOT TAKE NOTICE OF THIS POTENTIAL PROBLEM.THIS IS BEEN HAPPENING SINCE 11/19/2019 THE DATE WHEN I BOUGHT THE CAR TILL NOW

TL* THE CONTACT OWNS A 2015 MERCEDES-BENZ C300. THE CONTACT STATED THAT THE CHECK ENGINE WARNING LIGHT WAS ILLUMINATED. THE VEHICLE WAS TAKEN TO THE LOCAL DEALER MERCEDES-BENZ OF LOS ANGELES (1801 S FIGUEROA ST, LOS ANGELES, CA 90015, (213)425-3100) AND THE MECHANIC WAS UNABLE TO DUPLICATE THE FAILURE. THE VEHICLE HAD NOT BEEN REPAIRED AS OF YET. THE MANUFACTURER HAD BEEN INFORMED OF THE FAILURE. THE FAILURE MILEAGE WAS APPROXIMATELY 78,000.

THERE IS A MAJOR ISSUE WITH THE 2015 M274 MERCEDES ENGINE REGARDING THE WRIST PINS. MERCEDES HAS ISSUED NUMEROUS INTERNAL SERVICE BULLETINS ABOUT THE ISSUE. THE ENGINES WERE MANUFACTURED WITH WRIST PINS WITH TOO MUCH TOLERANCE THAT SLAP AGAINST THE PISTON WHEN OPERATING THAT COULD LEAD TO PREMATURE ENGINE FAILURES. THERE ARE HUNDREDS OF COMPLAINTS ON ONLINE FORUMS OF PREMATURE ENGINE FAILURES (PRE 100K MILES). I CONTACTED MERCEDES AND THEY REFUSE TO DO ANYTHING TO FIX THIS PROBLEM THE REPAIR IS WELL OVER $8,000 AND THE AVERAGE PERSON JUST CAN NOT AFFORD IT. YOU DIAGNOSE THE PROBLEM BASED ON CHATTER DURING DECELERATION. PLEASE MAKE MERCEDES MAKE THIS RIGHT AND FIX THE AFFECTED CARS THE RIGHT WAY. I JUST BOUGHT THIS CAR AND I AM NOW IN THE HOLE OVER $20,000

EVERY TIME I START MY CAR IT SMELLS LIKE GAS AND IT'S SO STRONG TO THE POINT WHERE IT GIVES ME HEADACHES. ALSO I WAS ON THE FREEWAY AND THE ROADS WERE WET FROM PREVIOUS RAIN AND I ALMOST DIED AND HYDROPLANED ON THE FREEWAY. EVEN IF IT'S A SMALL BIT OF RAIN MY CAR STARTS SHAKING AS IF I DON'T HAVE CONTROL. I DO NOT FEEL SAFE IN THIS CAR AND I JUST GOT THE CAR A MONTH AGO.

INTERMITTENT FUEL LEAK. REAL BAD GAS SMELL IN CABIN COMING THROUGH THE VENTS. DRIVER SIDE, IN BACK, DOWN BETWEEN THE ENGINE AND BODY. THE FUEL LINES ARE PRESSURIZED, SO IT MIGHT ONLY LEAK WHEN THE PRESSURE BUILDS UP. I KEPT GETTING A STRONG GAS SMELL THE GARAGE AFTER PARKING FOR LONG PERIODS.

I HAVE THE SAME PROBLEM ABOUT STEERING HARDER WHEN ON LOWER SPEED, EVERY OIL LEVEL LOOKS TO BE PERFECT.

WHILE DRIVING ON THE HIGHWAY MY MY MERCEDES BENZ C300 2015 WITH 37000 MILES ,ENGINE BROKE, AND YOU ARE NOT EXPECTING THAT WHEN YOU ARE DRIVING AT 65 MPH. THE MECHANIC IS SAYING IT IS A WRIST PIN AND A CRACKED #1 PISTON AND IT IS A VERY COMMON ISSUE ON THAT CAR AND MERCEDES REFUSES TO RECALL OR FIX THE PROBLEM IM GOING TO LEAVE A LINK WITH ONE OF THE MANY WEBPAGES WITH AL LOT OF PEOPLE COMPLAINING ABOUT THAT PROBLEM.

GAS LEAK IN FUEL LINE, WHILE RECEIVING AN OIL CHANGE FROM A LICENSED MECHANIC, HE BROUGHT TO MY ATTENTION THAT, THERE WAS FUEL LEAKING FROM THE FUEL LINE AND SHOWED (FUEL LINE SOAKED WITH GASOLINE DIRECTLY UNDER THE ENGINE), I ALSO NOTICED THAT WHEN USING THE AC THE STRONG SMELL OF GASOLINE COMES THROUGH THE VENTS.

THIS CAR LEFT ME STRANDED ON THE SIDE OF THE ROAD. THE CAR WAS ON WORKING FINE DRIVING ALONG THEN ALL OF A SUDDEN PUSHING THE GAS PEDAL DID NOTHING AND THE CAR WOULD NOT MOVE. THE ENGINE SHUT OFF COMPLETELY. THE ENGINE WAS NOT GETTING GAS. THE ELECTRICAL AND EVERYTHING ELSE WAS ON IN THE CAR EXCEPT THE ENGINE. THE SYSTEM IN THIS CAR HAS A DOUBLE FUEL TANK THAT ONLY WORKS ON ONE SIDE. THE ENTIRE FUEL SYSTEM IS FAULTY. THE MANAGER AT MERCEDES TOLD ME HIMSELF THAT THIS IS A DESIGN FLAW IN THIS CAR. THERE IS NO REASON WHY A CAR WITH 24,000 MILES SHOULD HAVE BROKEN DOWN ON THE SIDE OF THE ROAD BECAUSE THE ENTIRE FUEL SYSTEM DOES NOT WORK. FAULTY AND HORRIBLE WORKMANSHIP ON A SUPPOSED LUXURY VEHICLE.
