2009 MERCEDES-BENZ C300 Complaints

PASSENGER SEAT AIRBAG SENSOR NOT WORKING WHEN SOMEONE SITS ON THE SEAT ALSO PASSENGER SIDE ELECTRICAL SYSTEM NOT WORKING AND CAUSING THE PASSENGER SIDE LIGHTS TO STAY ON WHEN VEHICLE IS OFF AND MERCEDES DOES NOT WANT TO DO ANYTHING ABOUT AND SAYS IT IS OUT OF WARRANTY AND I NEED TO PAY TO HAVE THE WHOLE SYSTEM REPLACED

ON MY 2009 MERCEDES C300, THE VEHICLE PULLED SIGNIFICANTLY WHEN THE BRAKES WERE APPLIED. THE REPAIR SHOP I USE CHECKED THE BRAKING SYSTEM AND FOUND NO ISSUES. THEY THEN DISCOVERED A REAR SUB-FRAME ISSUE. THE ENTIRE REAR SUB-FRAME WAS ROTTED OUT ON MY 2009 MERCEDES C300.THE VEHICLE HAD LESS THAN 79K MILES ON IT, DID NOT GOT OUT IN BAD WEATHER AND WAS GARAGED. I CONTACTED MY LOCAL MERCEDES DEALER AND THEY SHOWED NO INTEREST IN ADDRESSING THE PROBLEM UNDER ANY TYPE OF DEFECT RESOLUTION ISSUE. THE REPAIR SHOP I USE ORDERED A NEW SUB-FRAME FROM MERCEDES, WHICH NOW HAS A DIFFERENT DESIGN WHICH I ASSUME IS TO ADDRESS THE ISSUE ON THE ORIGINAL SUB-FRAME. WHEN THE REPAIR SHOP BEGAN TO REMOVE THE DEFECTIVE SUB-FRAME, A PART OF THE SUB-FRAME TORE AND BROKE APART DUE TO THE ROTTED METAL. HAD THE VEHICLE BEEN IN MOTION WHEN THE METAL TORE APART I CAN ONLY IMAGINE WHAT WOULD HAVE OCCURRED. I HAVE CHECKED VARIOUS MERCEDES OWNER FORUM BOARDS AND THIS APPEARS TO BE A COMMON ISSUE WITH IS MODEL YEAR. I HAVE THE REPAIR BILL BUT CAN NOT ATTACH A COPY DUE TO THE FILE SIZE.

THE REAR SUB FRAME IS RUSTED OUT AND DEALER SAID IT IS UNSAFE TO DRIVE. DEALER SERVICED VEHICLE SINCE PURCHASE. VERY SURPRISED SUB FRAME IS RUSTED OUT AND THIS IS NOT A RECALL. MY WIFE AND GRANDKIDS ARE THE MAIN USERS OF THIS VEHICLE. THANK GOD IT WAS IN FOR ITS MAINTENANCE WHEN ISSUE WAS FOUND AND NOT TRAVELING 65 MILES PER HOUR DOWN THE TURNPIKE. ONLY 10 YEARS OLD AND THEY WANT $3700 TO REPLACE RUSTED SUB FRAME!

MY C300 STRANDED ME IN DEMING, NM. WE HAD LEFT EL PASO HEADING HOME TO PHOENIX. QUICK BIO BREAK IN DEMENT, AND THAT'S WHERE MY C300 WOULDN'T START. THE SHOP IN DEMING SAID THAT THE CAR WOULD NEED TO BE TOWED BACK TO THE DEALER IN EL PASO. TURNED OUT MY STEERING COLUMN CONTROL LOCK MODULE NEEDED TO BE REPLACED. THE DEALERSHIP ORDERED THE PART AND TWO DAY AND $1,400 LATER I WAS ABLE TO DRIVE BACK TO PHOENIX. BETWEEN TOWING, LODGING IN DEMING AND EL PASO, MEALS, ETC I WAS OUT OVER 2K. THIS IS SO I CAN START MY CAR. ACCORDING TO MY LOCAL MB DEALER MY SERVICE ADVISOR SAID HE SEES ONE OR TWO A MONTH WITH THIS PROBLEM. I PICKED UP THE CAR IN 2012 WITH 50K MILES. THIS ISSUE CAME 70K TROUBLE FREE MILES LATER. AMAZED THAT ONE LITTLE PART COULD STRAND ME WITH NO WARNING.

STEERING WHEEL STUCK IN LOCKED POSITION. CAR WILL NOT START. LOTS OF RESEARCH ON THE ISSUE HAS SHOWN MANY PEOPLE HAVE THIS PROBLEM. THIS ISSUES HAPPENS WHEN THE CAR IS STATIONARY. MANY TIMES AT NIGHT WHEN I AM GETTING OFF WORK.

"TAKATA RECALL" WHEN I WAS DRIVING AFTER A OIL CHANGE, I HEARD A NOISE THAT SOUNDED LIKE SOMEONE HIT MY CAR. I WAS SCARED AND SHAKY SO I PULLED OVER COULD SEE ANYTHING BUT I HEARD A TICKING NOISE. THEN I REALIZED THE HEAD REST MINI AIR BAG BLEW UP AND THE WIRING INSIDE THE HEAD REST WAS BURNING. THIS HAPPENED WHILE I WAS DRIVING. I COULD HAVE GOT INTO AN ACCIDENT. I HAD TO PULL OVER RIGHT WHERE ALL THE TRAFFIC WAS BECAUSE MY HANDS WERE SHAKING AND I DIDN'T KNOW WHAT TO DO WITH THE BURNING SMELL. I HAD MY HAZARDS ON AND PEOPLE WENT AROUND ME. THEN ALL KINDS OF ALERTS WENT OFF ON MY CAR. I ONLY HAD IT FOR A YEAR AND A HALF IT SHOULDN'T DO THAT. SOMETHING IS REALLY WRONG AND THIS IS DANGEROUS WHILE SOMEONE IS DRIVING. MY TIRES AND ALL OF A SUDDEN THE MUFFLER IS MAKING NOISES NOW TOO WHAT IS GOING ON WITH THIS CAR. IT'S TREATED WELL I'M SCARED TO DRIVE IT NOW. I'M STILL MAKING PAYMENTS ON IT. IT'S WAS FOR ME FAIRLY NEW AND STILL GOOD, DO I THOUGHT. I'M VERY DISAPPOINTED AND NEED SOME ANSWERS. I WAS TOLD THAT MAYBE IT'S THE EPS CONTROL UNIT BUT HAVEN'T WENT TO MERCEDES DEALER YET BECAUSE I'M DISCOURAGED ABOUT THIS CAR AND I HAVEN'T BEEN FEELING GOOD.

SAFETY ISSUE REGARDING FAILURE OF REAR SUBFRAME. I AM THE ORIGINAL OWNER OF A 2009 C300 4MATIC SPORT. THIS VEHICLE HAS BEEN GARAGE KEPT ITS ENTIRE LIFE AND IS NOT IN A HIGH SALT OR SNOW ENVIRONMENT. MY WIFE WAS EXTREMELY LUCKY TO HAVE AVOIDED AN ACCIDENT IN THIS CAR DUE TO THE REAR SUBFRAME RUSTING THROUGH AND SEPARATING. WE BOUGHT THIS CAR BRAND NEW AND PAID A PREMIUM FOR MERCEDES QUALITY BECAUSE WE THOUGHT IT WAS THE SAFEST VEHICLE MADE. I AM EXTREMELY DISMAYED TO LEARN THAT WHEN MY WIFE CAME HOME AND SAID THE CAR WAS DRIVING WEIRD, THAT IN FACT SHE WAS DRIVING A CAR THAT WAS FALLING APART WITH MY 7 YR OLD DAUGHTER IN THE BACK AND COULD HAVE RESULTED IN A VERY SERIOUS ACCIDENT. WHEN SHE ARRIVED AT THE ALIGNMENT SHOP THE MANAGER THERE INFORMED HER THE CAR WAS UNSAFE TO DRIVE AND HE HAD NEVER SEEN ANYTHING LIKE THIS TYPE OF FAILURE OF THE FRAME BEFORE. MY WIFE HAD THE CAR TOWED TO THE MERCEDES DEALERSHIP FOR REPAIR BECAUSE IT WAS NOT SAFE TO DRIVE. THIS CERTAINLY SHOULD BE A SAFETY RECALL DUE TO A MANUFACTURING DEFECT OR USE OF POOR MATERIALS AND MERCEDES SHOULD COVER THE REPAIRS

REAR SUB-FRAME CORROSION ISSUE. STARTING HEARING CLUNKING NOISES COMING FROM REAR RIGHT OF THE VEHICLE. ALSO NOTICED THE CAR SEEMED TO PULL OR TWIST TO THE RIGHT WHEN BRAKING. I INSPECTED THE BRAKES, ALL 4 DISC BRAKES AND PARKING BRAKES LOOKED FINE, NOTICED SUB-FRAME RUST THROUGH. THIS LEVEL OF CORROSION ON A KEY STRUCTURAL COMPONENT IS DANGEROUS. IT SEEMED OBVIOUS TO ME THIS WAS A MANUFACTURING ISSUE. THE CAR IS IN EXCELLENT CONDITION NO OTHER CORROSION ISSUES, AND HAS BEEN WELL MAINTAINED AND KEEP IN A HEATED GARAGE SINCE WE PURCHASED IT 6 YRS AGO. WE TOOK IT TO THE MERCEDES DEALERSHIP, HAD THEM CONFIRM THE ISSUE, AND REGISTERED A REQUEST TO MERCEDES CORPORATE TO HELP FIX THIS ISSUE. THEY DENIED THAT REQUEST. THE LOCAL SERVICE DEPT. INDICATED HOW DANGEROUS THIS ISSUE IS AND THE CAR SHOULD NOT BE DRIVEN. THE COST TO FIX THIS =$2600.
