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.
Fuel/propulsion system, Oct 5, 2020
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.

SUNROOF NO LONGER CLOSED SHAKES AND RATTLES, SEEMS LIKE A SAFETY ISSUE DURING A POSSIBLE ROLLOVER
Steering, Air bags, Service brakes, Sep 9, 2020, crash
WHILE DRIVING MY 2015 C250 COUPE, I HAD TO BRAKE HARD AS I WAS TRYING TO AVERT STOPPED HEAVY TRAFFIC. WHEN I SLAMMED ON THE BREAKS, THE STEERING WHEEL, COLUMN AND ENTIRE VEHICLE LOCKED UP. I WAS UNABLE TO TURN THE WHEEL ENTIRELY. AS A RESULT, MY VEHICLE SLIDE INTO ANOTHER VEHICLE FROM BEHIND. BECAUSE BOTH THE STEERING AND BRAKES LOCKING, I WAS UNABLE TO MANEUVER THE VEHICLE TO AVOID THE STOPPED TRAFFIC. THE AIRBAGS ALSO DID NOT DEPLOY AS THEY SHOULD HAVE.
Fuel/propulsion system, Sep 4, 2020
I 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. FUEL IS A VERY CRITICAL SAFETY PROBLEM AND USUALLY WE CANNOT TAKE NOTICE OF THIS POTENTIAL PROBLEM.

I TOOK MY CAR IN FOR A MULTI POINT INSPECTION AT THE END OF NOVEMBER 2019 TO MERCEDES OF BELLEVUE. I BEGUN SMELLING GASOLINE FROM THE INSIDE CABIN OF MY CAR A FEW DAYS AFTER THE SERVICE AND HAD TO TAKE THE CAR BACK TO THE DEALERSHIP. THEY FOUND THAT FUEL HOSES GOING TO THE HIGH PRESSURE FUEL PUMP TO BE LEAKING FUEL. WITH THIS BEING A POTENTIAL FIRE HAZARD AND A SAFETY ISSUE, I ARGUED WITH THE DEALER THAT IT SHOULD BE COVERED UNDER WARRANTY, WHICH I STILL HAD A CPO WARRANTY FROM PURCHASING THE VEHICLE FROM THIS SPECIFIC DEALERSHIP. I DID SOME RESEARCH ONLINE AND FOUND THAT, THIS IS A VERY COMMON ISSUE WITH MY VEHICLE MODEL, 2015 MERCEDES BENZ C300. I AM UNSURE WHY THIS ISSUE IS NOT YET RECALLED BY THE MANUFACTURER OR WHY THE DEALERSHIP DID NOT HONOR THIS ISSUE TTO BE COVERED UNDER WARRANTY.. AS A CONCERNED CUSTOMER OF THE HAZARDOUS POSSIBILITIES A FUEL LEAK COULD CAUSE, I STILL MOVED FORWARD WITH PAYING FOR THE REPAIR OUT OF POCKET VERSUS CONTINUING TO DEBATE WITH THE FINANCE AND SERVICE PERSONNEL THAT IT SHOULD BE COVERED UNDER WARRANTY THAT I STILL HAD AT THE TIME.

I STARTED EXPERIENCING LOUD WIND NOISE COMING FROM THE TOP OF MY CAR NEAR MY WINDSHIELD WHEN DRIVING OVER 40MPH. I PULLED OVER AND EXAMINED THE AREA AND FOUND THAT THE TOP LEFT GLASS PANEL IN FRONT OF THE SUNROOF ON MY 2015 MERCEDES BENZ C300 WAS SLIGHTLY PROPPED UP. IT SEEMED TO BE A POSSIBLE SEAL OR GLUE ISSUE CAUSING THE GLASS PANEL TO BE SLIGHTLY LOOSE AND ALLOWING AIR IN. I CALLED MERCEDES AND MADE THE NEXT AVAILABLE APPOINTMENT FOR SERVICE A FEW DAYS OUT. WHILE DRIVING ON THE FREEWAY, I BEGUN TO HEAR THE WIND NOISE AGAIN BUT FOLLOWED BY A LOUD RIP FROM THE ROOF OF MY CAR THIS TIME BUT DID NOT SEE ANYTHING IN SIGHT. WHEN I PULLED OVER, THE GLASS PANEL WAS COMPLETELY MISSING AND WENT FLYING SOMEWHERE ON THE HIGHWAY, CAUSING A ROAD HAZARD. IT WAS TORN OFF THE CAR AND THE ROOF OF THE CAR IS NOW EXPOSED.

THE VEHICLE WAS THANKFULLY NOY IN MPTION WHEN MY PANARAMA SUNROOF AND THE SHADES FAILED. THE SHADES I UNDERSTAND ITS NOT A SAFETY PROBLEM, BUT THE SUNROOF NOT BEING ABLE TO HOLD IN PLACE AS IT OPENS IS DIFFERENT. WHEN THE SUNROOF OPENED, THE REAR OF THE ROOF WAS NOT IN PLACE AND SHAKY. WHEN I TRIED TO CLOSE, IT HAD NOT LOCKED ITSELF RIGHT BACK IN PLACE, WHERE I HAD TO TAKE IT TO A MECHANIC JUST TO HAVE IT SHUT TO AVOID THE RAINSTORM YESTERDAY. I RECENTLY DID SOME RESEARCH AND READ THROUGH SOME ARTICLES, HAD A FRIEND OF MINE TAKE A LOOK AT IT AND IT SEEMS TO BE VERY SIMILAR, ALMOST THE SAME AS THE RECALL THEY HAVE DONE ON OTHER YEAR MAKE FOR THE PANARAMA ROOF.

ON JULY 19, 2020, I WAS DRIVING MY MB C300, ON HIGHWAY 301 IN BRADENTON FLORIDA. SUDDENLY, I HEARD WHAT SOUNDED LIKE A GUNSHOT. I WAS TERRIFIED. ONCE, I CALMED DOWN AND WAS ABLE TO GET TO A SAFE LOCATION, UPON EXAMINATION, I DISCOVERED THAT MY SUNROOF HAD SPONTANEOUSLY SHATTERED. THERE WAS ABSOLUTELY NO EVIDENCE OF ANY TYPE OF FOREIGN OBJECT CAUSING THE SUNROOM TO SHATTER. FORTUNATELY, WHEN THE LOUD BANG OCCURRED, I HAD THE PRESENCE OF MIND TO NOT LOSE CONTROL OF MY CAR IN WHAT COULD HAVE CAUSED AN ACCIDENT. ALSO, IF THE SUNROOF HAD BEEN PARTIALLY OPENED THE GLASS CHARDS COULD HAVE CAUSED SIGNIFICANT INJURY. THIS IS COMPLETELY AND UTTERLY UNACCEPTABLE. MERCEDES BENZ IS A LUXURY CAR MANUFACTURER, KNOWN FOR SUPERIOR ENGINEERING. THIS SHOULD NOT HAVE HAPPENED, UNDER ANY CIRCUMSTANCES.
