MY SUNROOF EXPLODED/SHATTERED WHILE I WAS DRIVING TODAY, TRAVELING AT A SPEED OF 45MPH ON CITY ROAD AFTER TURNING A CORNER. OUTSIDE TEMP WAS AROUND 85 AND INSIDE CAR WAS 75. CAR HAS AROUND 6800 MILES, AND THERE WAS NOTHING THAT HIT THE SUNROOF. SCARY SITUATION FOR THE DRIVER! CAR IS CURRENTLY UNDER WARRANTY AND AT THE DEALER FOR REPAIR, BUT THEY WANT MY INSURANCE TO PAY. I INSIST THIS BE INVESTIGATED BECAUSE I BELIEVE IT TO BE A MANUFACTURE DEFECT

I WAS DRIVING 580-E AND MERGING ONTO I-5 S WHEN I HIT A HUMONGOUS POT HOLE WITH MY LEFT FONT TIRE CAUSING IT TO IMMEDIATELY BLOW OUT. THAT IN-TURN CAUSED MY STABILITY TRACKING TO ENGAGE, WHICH CAUSED ME TO SLOW DOWN DRASTICALLY. THAT CAUSED ANOTHER VEHICLE TO NEAR MISS RAMMING ME IN THE BACK AND ME SIDE SWIPING ANOTHER VEHICLE. I WAS DRIVING APPROXIMATELY 70 MPH AND ALMOST LOST CONTROL OF THE VEHICLE AND HAD TO IMMEDIATELY PULL OVER TO A VERY NARROW SHOULDER OF THE ROAD WITH MY EMERGENCY FLASHERS BLINKING. TO ENSURE THE SAFETY OF THE VEHICLE, MY SELF AND OTHER PASSENGERS IN THE CAR, I HAD TO DRIVE APPROXIMATELY 0.5 MILES TO THE NEXT EXIT (67) TO SAFELY GET MY VEHICLE OFF THE ROAD TO A SAFE LOCATION. I THEN CALLED A TOW TRUCK TO TOW MY VEHICLE BACK TO SANTA ROSA WHERE I LIVE TO GET THE TIRE REPLACED AND FRONT BUMP REPAIRED. I AM UNSURE OF THE CAUSE OF THE UNSAFE CONDITION OF THE HIGHWAY OR WHAT CAUSED THE POT HOLE. THERE WERE SEVERAL CARS STRANDED WITH DAMAGES TO THEIR VEHICLES AS WELL. ONE PERSON CAME TO THE SAME EXIT (FOOD MART ON PATTERSON ROAD) WITH A BLOWN OUT TIRE AS WELL. I HAVE HER CONTACT INFORMATION IF YOU NEED TO CONTACT HER.

WHILE DRIVING, THE CAR LOSES THROTTLE AND THE ENGINE DOES NOT FUNCTION AT ALL. THE FOLLOWING ERROR SHOWS ON THE DASH: "INOPERATIVE SEE OPERATOR'S MANUAL". WHEN THIS HAPPENS, YOUR ONLY CHOICE IS TO COAST TO A SAFE PLACE. AFTER RESTARTING THE CAR, IT WILL FUNCTION FOR A SHORT TIME, ONLY TO REOCCUR. THIS OBVIOUSLY CAN BE DEADLY IF YOU CANNOT GET OFF THE HIGHWAY BEFORE THE CAR COMES TO A STOP. THIS HAS HAPPENED AT VARIOUS SPEEDS. *TR

NEW CAR PURCHASES IN 2015, FEWER THAN 25000 MILES. WHILE DRIVING LOCALLY, "COLLISION PREVENTION ASSIST" MALFUNCTION AND "CHECK ENGINE" LIGHTS LIT UP THE DASH BOARD. VEHICLE WOULD NOT PICK UP SPEED AND DRIVING WAS WEIRD. WAS ABLE TO DRIVE TO DEALERSHIP WHICH IS ABOUT 8 MILES AWAY. SITUATION COULD BE POTENTIALLY DANGEROUS IF HAPPENS ON A HIGHWAY AND IT WARRANTS ATTENTION. *TR
Electrical system, Jan 5, 2017
WHILE ACCELERATING FROM A STOP LIGHT FROM 0 TO SLIGHTLY OVER 40 MPH RECEIVED ERROR CODE OF ANTI COLLISION ASSIST INOPERABLE AND THE VEHICLE WENT FROM 40 MPH TO 0 LIKE I HIT A TREE. IT WAS NOT A SLOW SMOOTH MOTION OF SLOWING TO A STOP. THIS WAS A VIOLENT STOP THROWING ME FORWARD AND CAUSED MY SEAT BELTS TO ACTIVATE. IT SHOULD BE NOTED THAT THERE WAS NOT A SINGLE PERSON IN FRONT OF ME, BEHIND ME OR BESIDE ME. THIS WAS NOTHING SHORT OF A MIRACLE BECAUSE IF ANYONE HAD BEEN BEHIND ME, I WOULD HAVE BEEN REAR ENDED AND IF ANYONE HAD BEEN IN THE RIGHT HAND LANE I WOULD HAVE HIT THEM AS THE VEHICLE PULLED TO THE RIGHT VERY HARD WHEN IT MALFUNCTIONED. I TOOK THE CAR TO THE DEALER AND TOLD THEM I DID NOT WANT THE CAR BACK UNLESS THEY COULD DETERMINE WHAT HAD HAPPENED AND COULD PROMISE THAT IT WOULD NEVER HAPPEN AGAIN. UPON READING SO MANY COMPLAINTS ABOUT THE SAME LIFE THREATENING ELECTRICAL MALFUNCTION, THERE IS NO POSSIBLE WAY THAT MERCEDES BENZ IS NOT FULLY AWARE OF THE POTENTIAL FOR SERIOUS INJURY OR DEATH. I HAVE CALLED MB USA AND WAS TOLD THAT I WOULD NEED TO FILE A CUSTOMER INQUIRY. DONE. I PURCHASED THE VEHICLE IN APRIL 2016 WITH 7,200 MILES ON IT. I AM COMPLETELY TERRIFIED TO DRIVE THE CAR.

WHILE I WAS DRIVING ON THE HIGHWAY & LOCAL ROADS, THE CAR SUDDENLY BECAME UNRESPONSIVE AND STARTED SHOWING MESSAGES THAT ALL SYSTEMS ARE INOPERATIVE. PRE SAFE FUNCTIONS LIMITED,AND INOPERATIVE TRACTION CONTROL LIGHT COMES ON ALONG WITH THE BLINDSPOT NOT ACTIVATED, ESP SYSTEM WAS OFF AS WELL. THE CAR STARTED SLOWING DOWN AND HAD TO BE PULLED OVER TO TURN OFF AND ON. THIS HAS HAPPENED 3-4 TIMES AND ON BUSY ROADS, CAR IS SENT TO THE SHOP AND ONLY HAS 27000 MILES. I AM SCARED TO DRIVE AS I COULD DIE IN A CAR ACCIDENT BECAUSE OF THIS [XXX] CAR. MERCEDES NEED TO RECALL THIS ASAP, IF THEY ARE NOT THEN WE SHOULD OPEN A CLASS ACTION LAWSUIT AGAINST THEM AS THEY ARE PLAYING WITH OUR LIVES.

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

I HEARD A VERY BIG DEVASTATING NOISE WHILE DRIVING MY 2015 MERCEDES BENZ-C300 ON A LOCAL ROAD IN RALEIGH, NC AT ABOUT 40 MPH. SINCE I DID NOT SEE ANY TPMS (TIRE PRESSURE MONITORING SYSTEM) OR ANY OTHER KIND OF ALERT ON THE SCREEN, I CONTINUED TO DRIVE. AFTER DRIVING ABOUT 2 MORE MILES, I HEARD ANOTHER BIG POP AND THE CAR BECAME NON-DRIVABLE BY THEN. I DID NOT FEEL HITTING ANY OBJECT OR GOING THRU A POT HOLE. THAT'S WHEN I GOT DOWN THE CAR AND NOTICED THE RIGHT FRONT TIRE OUTER WALL GOT SEPARATED FROM THE TIRE AND THE THE TIRE WAS JUST FLAT TO THE GROUND. I COULD NOT, OF COURSE, DRIVE FURTHER. THIS HAPPENED ON SATURDAY (10/1/16) EVENING AND IT IS A RUN-FLAT TIRE, BUT COULD NOT DRIVE FURTHER AND THERE WAS NO SPARE IN THE CAR. SO, I HAD TO WAIT UNTIL TODAY (10/3/16) TO GET IT TOWED TO THE NEAREST BENZ DEALER IN RALEIGH TO GET THE TIRE REPLACED. IT WAS A VERY FRUSTRATING HALF A DAY ATTENDING TO THIS REPAIR. THERE ARE A COUPLE OF ISSUES HERE. (A) QUALITY ISSUE: WHY THE CONTINENTAL TIRE TIRE GAVE AWAY SO QUICKLY WITH ONLY ABOUT 23.5K MILES ON THE ODOMETER, WITHOUT HITTING ANY OBJECT? (B) SAFETY ISSUE: THIS WOULD HAVE BEEN A DISASTER IF I WERE ON A ROAD TRIP WITH FAMILY ON A NATIONAL HIGHWAY, ESPECIALLY, ON A SATURDAY EVENING WITHOUT A SPARE TIRE. (C). SYSTEM RESPONSE ISSUE: WHY MB SYSTEM DID NOT GIVE ANY KIND OF ALERT IN SPITE THIS MAJOR BLOW-OUT? I WOULD HESITATE TO BUY ANOTHER CAR WITHOUT A SPARE TIRE. I HOPE THE NHTSA WILL CONSIDER SERIOUSLY DISCOURAGING RUN-FLAT TIRES IN THE CARS UNLESS A SPARE TIRE IS PROVIDED, UNTIL SUCH TIME THE RUN-FLATS ARE EXTREMELY SAFE AND STURDY. THANKS.

IT HAPPENED TWO TIMES THE PAST 20 DAYS. CAR ENGINE STOPPED SUDDENLY WHILE DRIVING. FIRST TIME AT A SPEED OF ABOUT 20 MPH, SECOND TIME ON HIGHT WAY ABOUT 70 MPH. IT WAS EXTREMELY DANGEROUS THE SECOND TIME BECAUSE I WAS RIGHT AT THE PORT GETTING ONTO THE HIGH WAY AND I FOUND THE ENGINE WENT OFF. NO RESPONSE WHILE PUSHING THE ACCELERATOR PEDAL DOWN. I DID NOT HAVE TIME CHECK WHAT THE PROBLEM WAS BECAUSE TWO OTHER VEHICLES AT BACK ALMOST CRASH ON ME. I STOPPED THE VEHICLE ON THE SIDE OF THE HIGH WAY ENTRANCE IMMEDIATELY AND RESTARTED THE VEHICLE (I KNEW FROM LAST TIME IT WORKED BY DOING THIS) AND GOT BACK ON THE ROAD. THIS WAS A SERIOUS/FATAL PROBLEM. I SAW OTHERS COMPLAIN ABOUT THEIR MERCEDES-BENZ C SERIES HAVING SIMILAR ENGINE SHUTTING OFF ON THE ROAD PROBLEM, TOO. THERE WAS ONE PERSON ASKED ON YAHOO ANSWERS ABOUT THE SAME PROBLEM, HOWEVER HE DID NOT GET A RESPONSE FROM ANYONE. HTTPS://ANSWERS.YAHOO.COM/QUESTION/INDEX?QID=20151004200837AASQX6B I'M ALSO MAKING SOME SCREEN SHOTS OF PEOPLE WITH C300 FILED COMPLAINS ABOUT THE PROBLEM. THE MANUFACTURE NEED TO PAY ATTENTION TO THE PROBLEM.

COLLUSION PREVENTION SYSTEM INOPERATIVE. CAUSES CAR TO SLOW SLOW DOWN AND OR STOP WHILE ON THE ROAD. POSES A SEVERE LIFE THREATENING DRIVING CONDITION FOR ME AND OTHER DRIVERS. MANY OTHER MERCEDES BENZ OWNERS ACROSS THE USA, CANADA, AND JAPAN ARE COMPLAINING OF THE SAME ERROR MESSAGE AND ISSUES. MY MBUSA ADVISOR STATED HER VEHICLE IS DOING THE SAME THING. MY SERVICE ADVISOR AT THE DEALERSHIP STATED ITS MICE THAT ARE EATING THE WIRES. I AM TAKING MY VEHICLE TO TWO OTHER MECHANICS FOR OPINIONS ON THE CAUSE OF THE ERROR MESSAGE. I HAVE DOCUMENTS FROM OTHER MERCEDES BENZ OWNERS WHO HAVE COMPLAINED OF THE SAME ISSUE AND ERROR MESSAGE.

THE MANDATORY REQUIRED TIRE PRESSURE MOTORING SYSTEM (BECAUSE IT HAS RUN FLAT TIRES) ON ONE OF THE WHEELS FAILED AND THEY CLAIMED THIS IS NOT COVERED BY EITHER THE MANUFACTURER'S WARRANTY OR THE TIRE PROTECTION WARRANTEE. I WAS TOLD THIS ON 6/15 2015 BUT THE ORIGINAL COMPLAINT I MADE ABOUT AIR PRESSURE INT HE LEFT REAR TIRE WAS WELL WITHIN THE WARRANTEE PERIOD.

MULTIPLE INCIDENTS OF 'COLLISION PREVENTION ASSIST PLUS INOPERATIVE'. CAR LOSES ALL POWER UNTIL RESTARTED. THIS HAPPENED SEVERAL TIMES, ONCE ON AN INTERSTATE AT 65 MPH CREATING A DANGEROUS SITUATION. I HAD TO PULL OVER SEVERAL LANES ON THE INTERSTATE WITH NO POWER WHILE OTHER CARS HAD TO AVOID ME. I BROUGHT THE CAR INTO THE DEALER AND AFTER A WEEK OF REPAIRS, THE SAME FAULT HAS OCCURRED TWICE IN THE FIRST 24 HOURS AFTER RETURN OF VEHICLE. FAULT OCCURRED AT 60 MPH DURING A PASSING MANEUVER ON A 2 LANE ROAD. AGAIN, WE WERE PUT IN A VERY DANGEROUS SITUATION. THIS IS AN UNSAFE VEHICLE. ATTACHED IS A PICTURE OF THE DASHBOARD FAULT THAT I PHOTOGRAPHED AFTER THE CAR COASTED TO THE SIDE OF THE ROAD. THE CAR WOULD NOT MOVE UNTIL I TURNED IT OFF AND RESTARTED.

WAS DRIVING ON CITY STREET, AND THE COLLISION PREVENTION ASSIST DISABLED WARNING SIGN CAME ON AND I LOST POWER TO THE CAR. I'M TOLD THIS IS CALLED "LIMP MODE." I TRIED TO PICK UP SPEED BY PRESSING THROTTLE TO THE FLOOR, BUT GOT NO REACTION AT ALL. THEN SOME POWER CAME BACK, BUT NOT MUCH. EACH TIME I BRAKED TO STOP FOR LIGHT OR TURN THIS WOULD HAPPEN. AFTER I GOT HOME I RESTARTED THE ENGINE AND IT SEEMED NORMAL AGAIN. HOWEVER I WAS AFRAID TO DRIVE IT, ESPECIALLY SINCE IN THE LAST SIX MONTHS MY POWER STEERING ALSO FAILED, AND HAD IT TOWED TO DEALER. THEY RAN TESTS AND NO CODE FOR FAILURE WAS FOUND. THEY SAID THEY FOUND SOME SOFTWARE UPDATES WHICH THEY DID. UNFORTUNATELY, AFTER I PICKED UP THE CAR FROM SERVICE I SAW THAT MY MAIN COMPLAINT WASN'T EVEN MENTIONED. ONLY THAT I SOMETIMES HAD PROBLEM WITH COLLISION CONTROL WARNING GOING OFF FOR NO APPARENT REASON.

WHILE DRIVING "COLLISION PREVENTION ASSIST PLUS INOPERATIVE" MESSAGE APPEARS ON DASHBOARD. CAR LOSES ITS ABILITY TO ACCELERATE. OCCURRED TWICE (JANUARY 2015) ON CITY STREETS FORCING ME TO PULL OVER TO THE SIDE OF THE ROAD AND RESTART MY CAR, THE ERROR DISAPPEARS AND I AM ABLE TO DRIVE NORMALLY. 4/7/16 OCCURRED WHILE TRAVELING 65MPH ON AN INTERSTATE. I LOST ABILITY TO ACCELERATE AND WAS ALMOST REAR-ENDED BY A SEMI-TRUCK. THE VEHICLE WAS SERVICED AT A MERCEDES DEALERSHIP ON 1/11/16 THE HIGHWAY INCIDENT OCCURRED AFTER THE "FIX". IT IS CURRENTLY BACK AT THE DEALERSHIP BEING TESTED BY THE SERVICE DEPARTMENT. I AM TOLD THE CURRENT FIX IS TO REPLACE ALL THE SENORS. I HAVE OPENED A CASE WITH MBUSA TO REPURCHASE THE VEHICLE GIVEN THE INITIAL REPAIR DID NOT WORK AND PUT ME IN PERILOUS HIGHWAY SITUATION. I PURCHASED THE VEHICLE IN OCTOBER OF 2015.

TWO ISSUES, PURCHASED A CERTIFIED PRE OWNED VEHICLE. AT 8900 MILES, WE NOTICED THE CAR WAS IDLING VERY ROUGH ON A COLD START, ALMOST THE SOUND OF A DIESEL. THE SOUND WOULD RESOLVE AFTER 10 MINUTES OF DRIVING. SERVICE INFORMED US THAT THERE WAS A RECALL ON THE RODS AND PISTONS. WE HAD THE ENGINE REBUILT, AND THE NOISE IS THE SAME, IF NOT WORSE. THE CAR SOUNDS NOTHING LIKE LATERBUILD '15 MODELS OR '16 MODELS, NOR DOES IT RUN AS SMOOTHLY. SECONDLY, 5 OCCURRENCES INVOLVED INOPERATIVE COLLISION PREVENTION ASSIST WARNINGS AND INOPERATIVE ANTI-SKID WARNINGS APPEARING ON THE DASH CAUSING THE CAR TO REDUCE OPERATING SPEED TO 20MPH MAX. CAR NEEDED TO BE SHUT OFF AND RESTARTED AFTER A 5 MINUTE PERIOD EACH TIME THESE WARNINGS APPEARED, IN ORDER TO DRIVE OVER 20MPH. THE VEHICLE WAS SERVICED FOR THESE WARNINGS TWICE. THE FIRST SERVICE DIAGNOSED THE CAR WITH A CODING ISSUE. THE SECOND, INVOLVED REPLACING MODULES. THIS ALL OCCURRED DURING THE TWO MONTHS OF OWNING THE CAR. WE NOTICES SEVERAL SIMILAR COMPLAINTS REGARDING THE EARLY BUILD 2015 C300S, AND DECIDED TO CUT OUR LOSSES AND PURCHASE ANOTHER VEHICLE. WE DID NOT FEEL SAFE IN THAT CAR.
