MY CHECK ENGINE LIGHT STAYS ON WHICH MERCEDES BENZ STATED ITS THE MAGNETIC STABILIZER . WHICH WAS STATED THAT A RECALL MAYBE COMING. THIS CAUSES A MALFUNCTION IN HAVING YOUR EMISSION TO HAVE A FAULTY READING. I HAVE LESS THAN 120,000 ON IT . WHEN I HAVE TAKEN TO THE DEALERSHIP OR SERVICE THE LIGHT STILL CAME ON. TO MY UNDERSTANDING A CLASS ACTION WAS TAKEN AGAINST THE COMPANY BY THIS MODEL WAS SKIPPED OVER.

MY VEHICLE BECAME STUCK ON ONE GEAR AS I ENTERED THE FREEWAY. I HAD MY KIDS WITH ME AND I HAD TO PULL OVER THE SHOULDER. AFTER TURNING IT OFF AND ON AGAIN, IT RESET ITSELF. THIS HAS HAPPENED 4 TIMES NOW. NOW ITS HAPPENING ON STOP LIGHTS AS I TRY TO ACCELERATE, IT FEELS ITS DRAGGING AND CARS BEHIND ME ARE HONKING AT ME TO MOVE OUT OF THE WAY. IT IS UNSAFE AND I CANT AFFORD TO FIX IT OR BUY ANOTHER ONE. I RESEARCHED AND FOUND MUCH MORE PEOPLE ARE HAVING THIS PROBLEM. WHY HAS NO ONE DONE ANYTHING ABOUT THIS ISSUE? MY WIFE DRIVES THIS CAR AND I AM NOT SURE IF SHE WILL RESPOND IN THE SAME FASHION AS I DID WHEN PRESENTED WITH THIS DANGEROUS EVENT IF IT OCCURS. I WANTED SOMEONE WITH SOME CLOUT TO KNOW ABOUT THIS JUST IN CASE A DISASTER OCCURS I KNOW WHO TO GO AFTER. PLEASE MAKE MERCEDES BENZ RESPONSIBLE AND FIX THIS FREE OF CHARGE. THIS IS MY ONLY CAR AND IT WAS NOT CHEAP AND NOW TO PAY FOR A PROBLEM I AM SURE THEY KNOW IS A PROBLEM....ITS RIDICULOUS. PLEASE HELP BEFORE SOMEONE GETS HURT. JUST LOOK UP 2007 MERCEDES BENZ C230 STUCK ON GEAR AND YOU WILL SEE HOW BIG THIS ISSUE IS. I BOUGHT THE CAR IN JANUARY 2016.
Power train, Vehicle speed control, Mar 15, 2016
THE CAR STAYS IN FIRST GEAR AND I HAVE TO STOP AND PULL OVER. PUT IT IN PARK AND IT JERKS VERY BADLY GOING IT TO PARK. THEN I TURN IT OFF, AND BACK ON. THEN EVERYTHING GOES BACK TO NORMAL, UNTIL IT HAPPENS AGAIN. SO MANY PEOPLE HAVE THIS ISSUE AND THERE IS NO RECALL. WHAT ARE THEY WAITING FOR. THERE IS 113 COMPLAINTS ON THIS CAR AND ALMOST NONE ARE FROM THE ONLY RECALL THEY HAVE ACTUALLY ISSUED. THIS HAPPENS ON A RED LIGHT. IT HAPPENS ON THE HIGH WAY. IN REVERSE. I WISH I NEVER BOUGHT THIS CAR. SOME PEOPLE PAID 1500 DOLLARS TO FIX IT. I THOUGHT MERCEDES MEANT HIGH QUALITY. AT LEAST THEY CAN ADMIT THEIR MISTAKE AND FIX IT FOR THE PEOPLE SUFFERING BEFORE SOMEONE DIES. THE CAR HAS 94000 MILES. MY HONDA WENT TO 200,000 WITH OUT ISSUES.
Fuel/propulsion system, Mar 15, 2016
THIS VEHICLE SHOWS SAME SYMPTOMS AS WHAT WAS INVESTIGATED ON REPORT# VRTC-DCD-3206 BY NHTSA. UPON FILLING UP THE GAS TANK TO FULL, GAS LEAKS FROM SANDING UNIT UNDER REAR PASSENGER SEAT. FEW TIMES THE GAS HAS MADE ITS WAY OUT AND DRIPPED FROM REAR LEFT WHEEL WELL. REACHED OUT TO MB USA AND WAS TOLD THE RECALL WAS ONLY IN E-CLASS AND THEY WILL NOT EXTEND IT TO C-CLASS. I SEE THIS AS A POOR PRODUCT DESIGN AS THE CAR ONLY HAS UNDER 14,000 MILES. IT'S BOTH HEALTH AND ENVIRONMENTAL HAZARD.

TRANSMISSION WILL NOT SHIFT, GOES INTO LIMP MODE. TURN THE CAR OFF, WAIT A COUPLE MINUTES, RESTART THE CAR AND IT DRIVES FINE. THIS FIRST HAPPENED MAY 2015 WITH 66,000 MILES. OUR MECHANIC TOLD US THIS IS A VERY COMMON MERCEDES TRANSMISSION FAILURE. WE CHOOSE TO REPLACE THE FLUID, AND IT DID SEEM TO HELP. NOW WE HAVE 79,500 MILES AND IT GOES INTO LIMP MODE ONCE A WEEK. THE FLUID WAS SUPPOSED TO LAST 100,000 MILES. OUR MECHANIC SAID THE FLUID WE CHANGED WAS CLEAN. THIS IS A VERY DANGEROUS SITUATION, A KNOWN MERCEDES DEFECT WITH THE TRANSMISSION ELECTRONICS. THE NEXT STEP IF WE DECIDE TO KEEP THE CAR IS TO REPLACE THE TRANSMISSION CONDUCTOR PLATE. NEVER AGAIN WILL I BUY A MERCEDES. THIS CAR HAS BEEN BABIED BY MY WIFE, AND HAS LESS THAN 100,000 IN 9 YEARS. ANY JAPANESE AUTOMOBILE WOULD HAVE EASILY PROVIDED DOUBLE THE LIFE BEFORE FAILURE. THIS IS TOTALLY UNACCEPTABLE TO BE FACING THOUSANDS OF DOLLARS IN REPAIRS TO A CAR WITH ON 79,500 MILES.

STRONG GAS ODOR IN GARAGE & HOUSE. THIS OCCURS AFTER FILLING UP CAR AND PARKING CAR IN GARAGE OVERNIGHT.
Fuel/propulsion system, Mar 4, 2016
I PURCHASED A 2007 MERCEDES BENZ C230 IN 2006 FROM THE MERCEDES-BENZ DEALERSHIP AND I HAVE HAD IT IN THE GARAGE.I'VE ONLY DROVE TO CHURCH AND THAT'S IT 700 MILES IS WHAT'S ON MY CAR.I'VE NOTICED ABOUT A YEAR AGO WHEN I PUT GAS IT, YOU CAN SMELL IT STRONG. I THOUGHT IT WAS BECAUSE OF THE TYPE GAS (SUPREME) WHAT I'VE BEEN USING. I TOOK MY CAR TO THE DEALERSHIP THIS MORNING TO GET A OIL CHANGE WHEN THE SERVICE ADVISOR TOLD ME THAT THE CAR WAS LEAKING FUEL.THERE ARE TWO RUBBER SEALS ONE GOES ON THE DRIVER SIDE AND THE PASSENGER SIDE UNDER THE BACK SEAT. HE TOLD ME THAT IS GOING TO COST $700.00. I ASKED HIM HOW IS DID THAT HAPPEN BECAUSE I DON'T DRIVE MY CAR LIKE THAT FOR SOMETHING TO GO WRONG WITH IT. HE STATES THAT IT IS VERY DANGEROUS AND DRIVING THE CAR COULD CAUSE A FIRE OR WORST BLOW UP.THE GAS IS LEAKING AND DRIVING THE CAR IF YOU SUDDENLY HAVE TO STOP THE GAS WOULD LEAK ONTO THE EXHAUST PIPE,IF THE PIPE IS HOT THERE IS A PROBLEM. I SAID WELL THAT HAS NOT COME FROM ME,I HAVE TAKEN CARE OF MY CAR SINCE I BOUGHT IT. THE SERVICE ADVISOR SAID SIR, NO THIS IS NOT SOMETHING THAT HAS BEEN DONE BY YOU.I SAID THIS SHOULD HAVE BEEN A RECALL BECAUSE MY CAR IS BRAND NEW NOT BY THE YEAR BUT BY THE MILEAGE AND FIR SOMETHING LIKE THIS TO BE SO DANGEROUS.HE AGREED AND SAID HE WILL FIX THE PROBLEM.HE PUT ME IN A RENTAL FROM FRI-MON AND SAID HE WILL CALL ME WHEN MY CAR IS FIXED. I GET HOME AND LATER AROUND 6PM HE CALLED ME AND SAID IT WAS SOMETHING ELSE WRONG FROM THE EFFECTS OF THE GAS LEAK AND NOW WANT TO CHARGE ME $1500.00 I TOLD HIM I DON'T HAVE THAT KIND OF MONEY. AND I NEED HELP WITH THIS BECAUSE THIS IS RIDICULOUS I NEED TO KNOW IF THERE IS A RECALL OR SOMETHING.BECAUSE I SEEN I'M NOT THE ONLY PERSON WHO HAS THIS PROBLEM.I FEEL THE DEALERSHIP SHOULD BE HELD RESPONSIBLE.THE SERVICE ADVISOR AGREED WITH ME THAT IT SEEMS TO BE A MALFUNCTION ON THEIR END. I NEED HELP! THANK YOU *TR

Power train, Jan 13, 2016
ON SEVERAL OCCASIONS I HAVE EXPERIENCED MY VEHICLE GOING INTO LIMP MODE DUE TO THE SAME TRANSMISSION PROBLEM THAT EVERYONE ELSE SEEMS TO BE HAVING. IT HAS HAPPENED WHEN PULLING AWAY FROM AN INTERSECTION, TRYING TO OVERTAKE A SLOWER VEHICLE, TRYING TO GET UP TO SPEED ENTERING THE INTERSTATE, BUT NOTHING PARTICULAR SEEMS TO TRIGGER IT. FORTUNATELY, I HAVE ALWAYS BEEN ABLE TO PULL THE VEHICLE TO THE SIDE OF THE ROAD, SHIFT TO PARK, AND SHUT THE VEHICLE OFF AND RESTART IT, WHICH WOULD FIX THE PROBLEM. UNTIL NOW. AFTER THE LAST TIME IT HAPPENED, THE VEHICLE WILL NOT RESET. IT IS STUCK IN WHAT APPEARS TO BE SECOND GEAR. I CAN'T BELIEVE THAT MERCEDES BENZ HAS NOT BEEN FORCED TO RECALL THE VEHICLES EQUIPPED WITH THE 722.9 TRANSMISSION. I HAVE RESEARCHED THIS ON THE INTERNET AND IT APPEARS TO BE A PROBLEM WORLD WIDE. IT HAS CAUSED ACCIDENTS RESULTING IN INJURY AND DEATH AND IT IS CLEARLY A SAFETY ISSUE. THE PROBLEM IS CAUSED BY A DEFECTIVE TRANSMISSION CONTROL MODULE WHICH IS LOCATED INSIDE THE TRANSMISSION, ON TOP OF THE VALVE BODY. MERCEDES REFUSES TO SELL THE PART TO ANYONE OTHER THAN MERCEDES REPAIR SHOPS. MY CAR ONLY HAS 85,000 MILES ON IT, I BOUGHT IT USED 6 MONTHS AGO.

IN NOVEMBER OF 2012 MERCEDES-BENZ USA INITIATED A SERVICE CAMPAIGN THAT AFFECTED APPROX. 1,064,723 VEHICLES. THE DEFECTIVE PART WAS THE CAMSHAFT SOLENOID. MBUSA SENT THIS NOTICE TO ALL DEALERSHIPS, BUT FAILED TO NOTIFY THE VEHICLE OWNERS DIRECTLY. THEY APPARENTLY DID NOT DEEM THIS TO BE A SAFETY RECALL AND FELT NO OBLIGATION TO NOTIFY THE CONSUMER. HOWEVER, WHEN THE SOLENOID MALFUNCTIONS DUE TO THE DEFECTIVE PART IT DOES IN FACT AFFECT THE PERFORMANCE AND DRIVING ABILITY OF THE CAR. IF DRIVING ON THE HIGHWAY, IN WHICH IS THE CASE HERE, IT DOES BECOME A SAFETY CONCERN. IT SEEMS THAT MBUSA KNOWINGLY WITHHELD THIS INFORMATION FROM THEIR CONSUMERS. DURING THE TIME OF THEIR CAMPAIGN MY VEHICLE WAS ALSO UNDER WARRANTY AS WELL. MBUSA HAD AMPLE OPPORTUNITY TO NOTIFY THEIR CUSTOMERS OF THIS ISSUE TO HAVE IT CORRECTED. THEY NEVER ACTIVELY PROVIDED NOTICES TO CUSTOMERS DIRECTLY. DUE TO THE MALFUNCTION OF THE AFFECTED SOLENOID, MY VEHICLE HAD TO BE REPAIRED IN APRIL 2015. MY WARRANTY EXPIRED IN MARCH 2014. I HAD MY VEHICLE REPAIRED AT AN INDEPENDENT REPAIR SHOP AT A COST OF $232.93. MBUSA SHOULD BE HELD RESPONSIBLE FOR FAILURE TO NOTIFY THE VEHICLE OWNERS OF THIS POTENTIAL SAFETY HAZARD IF NOT CORRECTED, AS WELL AS THEY SHOULD BE REQUIRED TO REIMBURSE ANY OUT OF POCKET EXPENSES THAT WERE INCURRED AS A RESULT OF THIS ISSUE. I HAVE ATTACHED A COPY OF THE BULLETIN THAT MBUSA PROVIDED TO THEIR DEALERSHIPS, BUT AGAIN FAILED TO PROVIDE TO THE 1,064,723 CONSUMERS THAT WERE AFFECTED.

STRONG GASOLINE ODOR COMING FROM CAR. THE SMELL IS NOTICED AFTER THE CAR HAS BEEN DRIVEN AND IS PARKED IN MY GARAGE. I AM SCARED THAT THE FUMES CAUSED BY WHATEVER LEAK THIS MAY BE WILL IGNITE.
Fuel/propulsion system, Sep 29, 2015
STRONG FUEL ODOR AFTER FILLING UP MY CAR. AFTER 2 DAYS ODOR WAS STILL THERE. TOOK TO DEALERSHIP TO BE CHECKED AND WAS TOLD THAT THE FUEL SENDING UNITS NEED TO BE REPLACED AND WILL COST $1130.00.. I HAVE VERY LOW MILEAGE ON MY CAR 48,336.. THIS IS A HUGE SAFETY AND ENVIRONMENTAL ISSUE. VERY UNHEALTHY TO BREATHE IN FUEL VAPORS AND BAD FOR THE ATMOSPHERE. THIS IS EXACTLY THE SAME AS THE "E" CLASS RECALL. WHY WASNT THE "C" CLASS INCLUDED. PLEASE MAKE THIS A RECALL ON THE "C" CLASS.

Fuel/propulsion system, Aug 21, 2015
STRONG RAW FUEL ODOR WAS NOTICED AFTER FILL UP ON MULTIPLE OCCASIONS. INVESTIGATION FOUND THAT BOTH THE FUEL PUMP HOUSING AND THE FUEL SENDER HOUSINGS WERE CRACKED ALLOWING RAW FUEL TO LEAK OUT. THIS IS EXACTLY THE SAME AS THE E CLASS RECALL. THIS RECALL NEEDS TO BE EXTENDED TO INCLUDE THE C CLASS AS WELL AS THIS CAR HAS AN IDENTICAL FAILURE MODE. I FOUND THIS ISSUE WAS PREVIOUSLY REPORTED, AND WOULD LIKE TO SECOND THIS NOTED ISSUE. FOR MANY MONTHS HAVE NOTICED STRONG FUEL SMELL FROM LEFT REAR WHEEL WELL. MB DEALER CONFIRMS ABOVE SIMILAR DIAGNOSIS AND APPROXIMATELY 1K REPAIR COST, GAS IS LEAKING OUT AND POOLING ON TOP OF SENDER UNIT.

ENGINE MOTOR MOUNTS ARE CONSTRUCTED OF UNTREATED ALUMINUM. IT IS WELL KNOWN THAT SALT WILL REACT EASILY WITH ALUMINUM, EXTENSIVE CORROSION RESULTS. THE DRIVER SIDE MOTOR MOUNT SITS IN A POCKET IN THE FRAME, WHERE BRINE CAN LAY ON IT FOR PROLONGED PERIODS. OF NOTE, MANY HIGHWAY DEPARTMENTS ARE NOW USING A BRINE MIX, INCLUDING MAGNESIUM CHLORIDE, THAT WILL REACT WITH MOISTURE IN THE AIR TO CONTINUE THE CORROSION PROCESS. A RECENT STUDY BY VOLKSWAGEN CONFIRMS THAT THIS ACCELERATES THE CORROSION PROCESS. IN APRIL OR MAY OF THIS YEAR, I HAD TO HAVE THE MOTOR MOUNTS ON MY CAR REPLACED. ONE FAILED COMPLETELY, THE OTHER WAS SEVERELY CRACKED AND NEARLY THE SAME WAY. THE ENTIRE TOP OF THE DRIVER SIDE MOUNT WAS COMPLETELY MISSING, APPARENTLY FROM CORROSION. WHAT WAS LEFT WAS WHITE POWDER. THE PASSENGER SIDE ALSO SHOWED EVIDENCE OF SIGNIFICANT CORROSION. THE MECHANIC WHO WORKED ON MY CAR SAID THAT THIS WAS A KNOWN PROBLEM, AND NOT THE FIRST HE HAD SEEN. I AM EXTREMELY CONCERNED ABOUT THIS. A COMPLETE FAILURE OF MOTOR MOUNTS COULD CAUSE A SEVERE ACCIDENT, WITH WIRING AND OR FUEL LINES BEING SHEARED, AND LOSS OF CONTROL OF THE VEHICLE. THE BREAKAGE WOULD BE LIKELY TO OCCUR UPON ACCELERATION (THINK ABOUT ENTERING AN INTERSECTION) OR WHEN GOING OVER A BUMP. A COMPLAINT WAS FILED WITH MERCEDES CORPORATE OFFICES. I EXPLAINED THAT I WAS NOT LOOKING FOR ANY KIND OF FINANCIAL SETTLEMENT. I AM NOT. I WOULD LIKE THE PROBLEM ADDRESSED. IT HAS BEEN A FEW MONTHS NOW WITH NO RESPONSE. THIS SITUATION IS NOT ACCEPTABLE.
