2011 MERCEDES-BENZ C300 Complaints

THE PASSENGER SIDE OF THE CAR GOT FLOODED WITH WATER. THE DEALERSHIP FOUND THAT THE LEAK WAS FROM THE RIGHT SIDE SUNROOF DRAIN AND THAT THEY WOULD HAVE TO REMOVE THE HEADLINER AND PASSENGER SIDE INTERIOR CARPETING TO ACCESS THE AFFECTED AREAS. THE $795 ESTIMATE BALLOONED TO $1600 WHEN THEY SAID THAT THE SEATING WOULD HAVE TO BE REMOVED TO REMOVE THE ENTIRE CARPET BECAUSE THERE WAS MORE WATER THAT HAD GOTTEN INTO THE CAR THAN THEY ORIGINALLY THOUGHT! THIS SOUNDS LIKE A DESIGN DEFECT IN THIS VEHICLE! THIS COULD BE DANGEROUS WITH THE ELECTRIC POWER AND HEATED SEATS! *TR

I RECEIVED A SAFETY RECALL LETTER ON JUNE 2014 FOR TAIL LIGHT PROBLEM. I CALL THE DEALER IMMEDIATELY AND IT'S GOING TO BE DECEMBER AND THEY HAVE NOT DO ANYTHING. *TR

TL* THE CONTACT OWNS A 2011 MERCEDES BENZ C300. THE CONTACT STATED THAT THE DRIVER'S SIDE AIR BAGS DEPLOYED ON SEVERAL OCCASIONS. ON ONE OCCASION, THE CONTACT WAS ATTEMPTING TO EXIT A HIGHWAY AND THE HEAD RESTRAINT AIR BAG DEPLOYED CAUSING THE CONTACT TO BECOME UNCONSCIOUS. THE CONTACT SUSTAINED A HEAD CONCUSSION AND NECK INJURIES THAT REQUIRED MEDICAL ATTENTION. THE VEHICLE WAS NOT DIAGNOSED OR REPAIRED. THE MANUFACTURER WAS NOTIFIED OF THE FAILURE. THE APPROXIMATE FAILURE MILEAGE WAS 36,442.

WHEN COMING TO A STOP OR LETTING OFF THE ACCELERATOR PEDAL IT FEELS AS IF THE VEHICLE WAS REAR ENDED BY ANOTHER VEHICLE. I SUSPECT IT'S EITHER COMING FROM THE DRIVE SHAFT OR TRANSMISSION. I HAVE TAKEN THE VEHICLE TO THE DEALERSHIP A NUMBER OF TIMES BUT CAN NOT DUPLICATE AFTER IT HAPPENED GOING ON A TEST DRIVE WITH A TECHNICIAN. *TR

I BOUGHT THIS CAR NEW IN 2011. AFTER A COUPLE OF MONTHS, STARTED NOTICING A ROTTEN EGG ODOR COMING FROM MY CAR. THE SMELL SEEMS TO COME FROM UNDERNEATH THE CAR. USUALLY OCCURS WHEN I'M GOING 45MPH OR MORE GOING UP A HILL ON A HIGHWAY. TOOK IT TO THE DEALER TO CHECK, SO THEY TOOK THE CAR FOR A TEST DRIVE AND SAID THEY FOUND NO ODORS WHICH I DON'T UNDERSTAND WHY? THEY SAID IT MIGHT BE THE TYPE OF FUEL I USE FOR THE CAR MAY AFFECT IT, BUT I USE PREMIUM GAS ONLY FROM CHEVRON. MERCEDES REALLY NEED TO LOOK INTO THIS, BECAUSE THE SMELL IS HORRIBLE! I'VE BEEN DEALING WITH THIS SMELL FOR ALMOST THREE YRS. NOW. *TR

SUN ROOF AND LIGHTS INSIDE THE CAR STOPPED WORKING SUDDENLY CAUSING COMPLETE DARKNESS INSIDE THE CAR AT NIGHT TIME. *TR

PURCHASED THIS CAR BRAND NEW IN AUGUST OF 2011. SINCE THEN THE CAR HAS DIED 3 TIMES. THE FIRST TIME THEY THOUGHT IT WAS THE IGNITION. THE SECOND TIME, JUST 6 WEEKS AGO, THEY COULD NOT FIGURE OUT WHAT WAS WRONG SO AFTER 8 DAYS, THEY GAVE THE CAR BACK TO ME. OF COURSE WHILE THEY HAVE IT, IT STARTS RIGHT UP. WHAT HAS HAPPENED IS THAT I WOULD GET IN THE CAR AND IT SIMPLY WOULD NOT START, WON'T LOCK OR UNLOCK AND TRUNK WOULD NOT OPEN. NOT EVEN WHEN I TRIED THE KEY MANUALLY. IT SOUNDS ELECTRICAL TO ME. THE FIRST TIME IT HAPPENED, ONE OF THE MECHANICS TOLD ME HE HAD NOT SEEN THIS PROBLEM WITH MB IN 25 YEARS. I AM EXTREMELY UNHAPPY AND WILL NOT PURCHASE ANOTHER MB EVER AGAIN. *TR

AT ONLY 5000 CLUTCH AND FLYWHEEL "EXPLODED" ACCORDING TO DIAGNOSTIC AT PRINCETON DEALERSHIP. QEC CENTER IN JACKSONVILLE PROMISED TO PROVIDE RESULTS OF ANALYSIS TO DETERMINE CAUSE. ON 7/10/2013 I LEARNED UPON INQUIRY THAT QEC ADVISED PRINCETON DEALERSHIP TO DISPOSE OF PARTS WITHOUT GIVING ME THE OPPORTUNITY TO KEEP THOSE PARTS. I WISH TO KNOW WHY THIS HAPPENED; HOW COMMON IS THIS OCCURRENCE; AND WHAT IS MY RECOURSE IF THIS HAPPENS AGAIN. *TR

REPEATEDLY, VEHICLE REFUSES TO START ON FIRST TRY. INSERT KEY, STEERING WHEEL UNLOCKS. TURN IT, ALL LIGHTS COME ON. TURN TO START AND NOTHING HAPPENS. TURN SWITCH ALL THE WAY OFF AND THEN TRY AGAIN AND IT STARTS. *TR

LEFT SIDE TAIL LIGHT ASSEMBELY MELTED AND CAUGHT THE TRUNK ON FIRE. I HAVE 10 OF THESE C300S THAT ARE AFFECTED WITH THE SAME PROBLEM. I HAVE SPOKE WITH MERCEDES ON THIS ISSUE AND THEY ARE DECLINING TO DO THE REPAIR AT NO COST. THIS IS A SAFETY ISSUE AND SHOULD BE COVERED NO MATTER WHAT..I HAVE FOUND THAT THIS IS A COMMON PROBLEM WITH THESE CARS AND YET THERE IS NO RECALLS OR TSBS ON THIS ISSUE. ANY HELP ON THIS WOULD BE APPRECIATED.. *TR
