STRUCTURE:BODY
MY VEHICLE, A 2015 MERCEDES-BENZ C300 PURCHASED ON 6/6/15 WITH APPROXIMATELY 1200 MILES ON THE ODOMETER. ON MONDAY MORNING 7/20/15, AT APPROXIMATELY 5:30 AM PDT, I WAS DRIVING ON THE FREEWAY WHEN THE INTERIOR LIGHTS CAME ON AND THE DRIVERS DOOR POPPED OPEN. THERE WAS NO WARNING CHIME OR INDICATOR LIGHT PRIOR TO THIS HAPPENING. IT WAS VERY FRIGHTENING, AND CAUGHT ME BY SURPRISE. LUCKILY AT THE TIME THERE WERE NO OTHER CARS NEAR ME. I WAS ABLE TO SLOW DOWN AND SHUT THE DOOR. I CALLED THE DEALER AND THEY WERE CONCERNED AND HAD ME DROP IT OFF THAT AFTERNOON. PICKED UP ON TUESDAY AFTERNOON 7/21/15 APPROXIMATELY 5:30 PM PDT. I WAS TOLD THEY COULDN'T DUPLICATE THE DOOR OPENING. HOWEVER, LOOKING AT FORUMS ON THE INTERNET, THIS EXACT ISSUE HAS BEEN REPORTED BY OTHERS IN THE US AND AUSTRALIA AT LEAST. SOME WERE THE DRIVERS DOOR OTHERS WERE THE PASSENGERS DOOR. ONE REPORTED IT HAPPENING A SECOND TIME AFTER THE DEALER INSPECTED. I AM VERY CONCERNED ABOUT THIS HAPPENING AGAIN, AND POSSIBLY TRIGGERING AN AIR BAG OR AUTO-PARK. I DO NOT FEEL SAFE IN THIS CAR. I HAVE CONTACTED MERCEDES-BENZ USA VIA CHAT THIS MORNING 7/22/15 AND THEY WILL HAVE A CASE MANAGER CONTACT ME.

UNKNOWN OR OTHER
I WAS DRIVING TO COLORADO FROM TEXAS GOING NORTH ON HIGHWAY 285 ABOUT 15 MILES OUT OF CLINES CORNERS WHEN MY MOON ROOF JUST EXPLODED. GLASS WENT EVERYWHERE AND I QUICKLY SWERVED OFF THE ROAD. THERE WERE NO CARS AROUND THAT WOULD HAVE BEEN CAPABLE OF THROWING UP DEBRIS OF ANY KIND. I HAVE SUBSEQUENTLY DONE RESEARCH TO FIND THAT IT IS ALMOST IMPOSSIBLE FOR ROCKS OR DEBRIS TO BREAK A MOON ROOF. THIS SEEMS TO BE A SEMI-COMMON PROBLEM HOWEVER I AM STRUGGLING AT THE MOMENT TO GET MERCEDES TO COVER THE REPAIRS.

LUCKILY I TOOK CAR IN FOR A SAFETY CHECK AND BELT TENSIONER WAS FOUND TO BE SHREDDING. IT SHOULD LAST LONGER THAN THIS AND IS A SAFETY HAZARD. THIS EXTRA VISIT TO THE DEALER MAY HAVE SAVE ME FROM HAVING AN INCIDENT. I OTHERWISE NEVER WOULD'VE KNOW THE BELT WAS SHREDDING. *TR

LATCHES/LOCKS/LINKAGES
THE MERCEDES BENZ C 300W4 2010 HAS A PROBLEM WITH THE INSIDE DOOR LATCH.THE VEHICLE WAS BOUGHT AS A CERTIFIED PREOWNED FROM THE DEALER IN 2013. IT HAS LESS THAN 15000 MILES. I TOOK IT TO THE DEALER TODAY THEY KNEW WHAT WAS WRONG IMMEDIATELY. COST TO REPAIR APPROX. $1000. LOOKING ON LINE I FOUND NUMEROUS PEOPLE COMPLAINING ABOUT THE SAME PROBLEM. THERE IS AN OBVIOUS DESIGN FLAW THAT MERCEDES IS NOT WILLING TO ACCEPT. WHAT HAPPENS IN AN EMERGENCY IF YOU NEED TO GET OUT OF THE CAR AND THE HANDLE BREAKS? IN MY HUMBLE OPINION THIS IS A SAFETY ISSUE THAT SHOULD BE LOOKED INTO. *TR

STEERING
THE STEERING MALFUNCTION LIGHT CAME ON AND THE STEERING WHEEL LOST POWER. THE STEERING WHEEL LOCKED UP WHERE IT BECOME EXTREMELY DIFFICULT FOR ME TO MANEUVER THE CAR. I PUT ON MY EMERGENCY INDICATOR AND GOT THE CAR INTO A PARKING LOT AS SAFETY AS I COULD. HAD THIS OCCURRED WHILE I WAS GOING ON A ROAD WITH CURVES OR AT HIGH SPEED, I BELIEVE I COULD HAVE SUFFERED SEVERE BODILY INJURY. I CALLED MBRACE TO GET MY CAR TOWED. WHEN I TURNED MY CAR BACK ON AFTER APPROXIMATELY 5 MINS, THE ERROR WAS GONE AND IT WAS CLOSE TO 7PM AND THE SERVICE CENTER FOR THE DEALERSHIP WHERE I PURCHASED THIS CAR FROM WAS CLOSED. I DROPPED OFF THE CAR AT THE DEALERSHIP THE NEXT MORNING. TODAY IS THE SECOND DAY AND MY DEALERSHIP TELLS ME THAT THEY OPENED A CASE WITH MERCEDES AS THEIR WAS A FAULTY CODE IN THE STEERING ELECTRICAL BOX AND THEY WERE ADVISED BY MERCEDES TO SIMPLY RESET THE BOX AND DRIVE THE CAR FOR SOME TIME. HOWEVER THEY COULD NOT TELL ME WHY IT HAPPENED AND WHETHER THE RESET WILL PREVENT THE OCCURRENCE OF THE STEERING WHEEL MALFUNCTION AGAIN. I REFUSED TO TAKE A CAR BACK UNTIL ITS SAFETY IS PROVEN. THE DEALERSHIP IS KEEPING THE CAR UNTIL THEY HEAR FROM MERCEDES WHICH ACCORDING TO THEM COULD TAKE A FEW DAYS TO A WEEK+. I PURCHASED THIS CAR APPROXIMATELY 3 WEEKS AGO AND TO HAVE A MAJOR ISSUE WITH MY CAR WITH AND THE DEALERSHIP AND MERCEDES TO PROVIDE NO CONFIDENCE IN THE SAFETY OF THIS VEHICLE IS EXTREMELY APPALLING. ......UPDATED 12/17/15 *BF *TR UPDATED 10/11/2017*CN

SEAT BELTS, SERVICE BRAKES, AIR BAGS
I WAS DRIVING ON I-10 EASTBOUND AT APPROXIMATELY MILE MARKER 180 TO 182, WHEN I MADE A LANE CHANGE TO LET A FASTER MOVING VEHICLE PASS ME. I WENT FROM THE LEFT TO RIGHT LANE WITH THE CRUISE CONTROL SET AT 70 OR 75 MPH, (SPEED LIMIT ON I-10 IS 75 MPH). UPON ENTERING THE RIGHT LANE I SAW A TRACTOR TRAILER BRAKE LIGHTS, AND I SLAMMED ON THE BRAKE IN MY C 250, AND IT CAUSED THE CAR WHEELS TO LOCKED UP, WHICH ALSO CAUSED THE CAR TO SKID, AND SWERVE THE BACK END. THE C 250 DID SLOW DOWN SOME, BUT CAME TO A COMPLETE STOP AFTER THE C 250 IMPACTED THE REAR BUMPER OF THE TRAILER ATTACHED ON THE TRACTOR TRAILER TRUCK. THE C 250 SLIDE APPROXIMATELY 200 FEET, THERE WERE TIRE TRACKS ON THE PAVEMENT, WHICH SHOWS THE TIRES LOCKED UP. THE REAR ENDED OF THE CAR ALSO SWERVED, AND IT DIDN'T SEEM LIKE THE C 250 WAS SLOWING DOWN, ONCE THE BRAKES WERE APPLIED. THERE WAS ALSO SOME SKIPPING OF THE TIRES. THE AIRBAG DEPLOYED BUT WAS LATE, AND CAUSED ME TO IMPACT THE WINDSHIELD WITH MY HEAD. THERE IS ALSO A HOLE IN THE AIRBAG THAT IS BIGGER THEN A SILVER DOLLAR, WHICH SHOWS SIGN OF TEARING AND FRAYING. THE SEAT-BELT DETACHED AT IMPACT WHICH FORCED ME FORWARD AND DIDN'T RESTRAIN ME FROM ME HITTING THE STEERING WHEEL AND WINDSHIELD. *TR
