Sunroof clips are snapping on many w205 2015 mercedes c300 models causing the panoramic roof to come loose potentially flying off the car while driving this has the potential to hurt many people. Mercedes claims there is only a recall for models up to 2011 however hundreds of thousands of later model vehicles have the same issue. I read an article saying they recently opened a recall for the later models but my vin isn’t covered. If the 100 pound panoramic roof flies off while driving on the highway at 70 mph it can definitely kill someone. Please address my concern I cannot afford to come out of pocket for Mercedes defect and lack of help.

UPON SUBMITTING A CLAIM FOR MY "INOPERATIVE" SENSOR ISSUE AND THE CAR LOSING ALL POWER AT HIGHWAY SPEEDS. I DISCOVERED YOUR CLAIM ABOUT PANORAMIC SUNROOF DETACHMENTS. WELL YOU ARE IN LUCK AS I HAVE A LOVELY MERCEDES WITH A ROOF PANEL THAT I HAD TO GLUE TO THE TRACK AS IT CAME APART. THE HINGE ON RIGHT SIDE IS LOOSE. I CAN NO LONGER OPEN THE SUNROOF OR IT WILL CATCH WIND AS IF IT'S ABOUT TO DETHATCH. DRIVING THE SUNROOF IS SO LOOSE THAT IT WILL NOT CLOSE WITHOUT THE HELP OF HOLDING IT DOWN SO IT LOCKS INTO PLACE. BROUGHT IT INTO THE DEALER LAST SUMMER AND THEY BRUSHED IT OFF AND TRIED TO CHARGE ME OVER $2,000 TO GET IT FIXED. THEY SAID "COMMON ISSUE" I WOULD PRODUCE PICTURES, HOWEVER MY CAR IS CURRENTLY SITTING AT A MERCEDES FACTORY SHOP GETTING ITS OTHER SAFETY ISSUES TAKEN CARE OF.

I STARTED EXPERIENCING LOUD WIND NOISE COMING FROM THE TOP OF MY CAR NEAR MY WINDSHIELD WHEN DRIVING OVER 40MPH. I PULLED OVER AND EXAMINED THE AREA AND FOUND THAT THE TOP LEFT GLASS PANEL IN FRONT OF THE SUNROOF ON MY 2015 MERCEDES BENZ C300 WAS SLIGHTLY PROPPED UP. IT SEEMED TO BE A POSSIBLE SEAL OR GLUE ISSUE CAUSING THE GLASS PANEL TO BE SLIGHTLY LOOSE AND ALLOWING AIR IN. I CALLED MERCEDES AND MADE THE NEXT AVAILABLE APPOINTMENT FOR SERVICE A FEW DAYS OUT. WHILE DRIVING ON THE FREEWAY, I BEGUN TO HEAR THE WIND NOISE AGAIN BUT FOLLOWED BY A LOUD RIP FROM THE ROOF OF MY CAR THIS TIME BUT DID NOT SEE ANYTHING IN SIGHT. WHEN I PULLED OVER, THE GLASS PANEL WAS COMPLETELY MISSING AND WENT FLYING SOMEWHERE ON THE HIGHWAY, CAUSING A ROAD HAZARD. IT WAS TORN OFF THE CAR AND THE ROOF OF THE CAR IS NOW EXPOSED.

ON JULY 19, 2020, I WAS DRIVING MY MB C300, ON HIGHWAY 301 IN BRADENTON FLORIDA. SUDDENLY, I HEARD WHAT SOUNDED LIKE A GUNSHOT. I WAS TERRIFIED. ONCE, I CALMED DOWN AND WAS ABLE TO GET TO A SAFE LOCATION, UPON EXAMINATION, I DISCOVERED THAT MY SUNROOF HAD SPONTANEOUSLY SHATTERED. THERE WAS ABSOLUTELY NO EVIDENCE OF ANY TYPE OF FOREIGN OBJECT CAUSING THE SUNROOM TO SHATTER. FORTUNATELY, WHEN THE LOUD BANG OCCURRED, I HAD THE PRESENCE OF MIND TO NOT LOSE CONTROL OF MY CAR IN WHAT COULD HAVE CAUSED AN ACCIDENT. ALSO, IF THE SUNROOF HAD BEEN PARTIALLY OPENED THE GLASS CHARDS COULD HAVE CAUSED SIGNIFICANT INJURY. THIS IS COMPLETELY AND UTTERLY UNACCEPTABLE. MERCEDES BENZ IS A LUXURY CAR MANUFACTURER, KNOWN FOR SUPERIOR ENGINEERING. THIS SHOULD NOT HAVE HAPPENED, UNDER ANY CIRCUMSTANCES.

AT HIGHWAY DRIVING SPEEDS IN EXCESS OF 50 MPH, THE GLASS TRIM PANEL OF THE PANORAMIC SUNROOF VIBRATES AND FLAPS WILDLY. IT IS NOT SECURELY ATTACHED TO THE ROOF OF THE CAR. I TOOK IT TO THE DEALER TO HAVE IT REPLACED. IT WILL FLY OFF AND HIT THE VEHICLE BEHIND ME. IF THE VEHICLE BEHIND ME WERE A MOTORCYCLE, THE RESULTS WOULD BE DISASTROUS.

EXPLODING PANORAMIC ROOF. ON JANUARY 18, 2019, TWO HOURS INTO DRIVING FROM NEW YORK TO CANADA FOR A FAMILY VACATION, WITHOUT ANY WARNING AND FOR NO APPARENT REASON THE PANORAMIC ROOF TO OUR 2015 MERCEDES BENZ C300 4MATIC SUDDENLY AND VIOLENTLY EXPLODED. AT THE TIME OF THE OCCURRENCE THE HIGHWAY ROAD (I84E)WAS STRAIGHT, SMOOTH AND WE WERE AT CRUISING SPEED (60MPH), NO CARS ANYWHERE NEAR US IN FRONT OR FROM THE REAR. THE EXPLOSION SOUNDED AS IF A BOMB HAD GONE OFF OR IF WE HAD BEEN SHOT. TINY GLASS PARTICLES SPRAYED MY ENTIRE FAMILY INCLUDING MY WIFE, 2 DAUGHTER (12,15) AND OUR PUPPY. LUCKILY THE SUNSHADE COVERING UNDERNEATH THE GLASS ROOF CAUGHT THE LARGER PIECES OF BROKEN GLASS. AFTER MAKING SURE THE FAMILY WAS NOT INJURED I MANAGED TO FIND A LARGE PIECE OF CARDBOARD THAT I DUCT TAPE TO THE ROOF AND SLOWLY MADE OUR WAY BACK HOME, ENDING OUR TRIP. UPON ARRIVING HOME I DID LOTS OF RESEARCH AND TO MY SURPRISE FOUND THAT EXPLODING PANORAMIC ROOFS WAS MORE COMMON THAN I HAD EVER THOUGHT WITH MANY OWNERS GONE THROUGH THE EXACT SITUATION AS I. YET, MERCEDES REFUSES TO ACKNOWLEDGE THIS ISSUE AND PRESENTLY DOES NOT HAVE A RECALL ON THEIR PROBLEM. TO ADD INSULT TO INJURY WHEN I BROUGHT THE VEHICLE TO THE DEALERSHIP FOR A REPAIR, THE SERVICE ADVISOR ACTED AS IF THIS WAS NO BIG DEAL AND ALSO THAT HE HAS NEVER SEEN THIS ISSUE IN HIS 34 YEARS OF BEING THERE. I CAN ONLY ASSUME THAT THIS IS A FALSE STATEMENT SINCE THE VALLET PERSON WHO TOOK MY CAR SAID HE HAS SEEN IT ON QUITE A FEW OCCASION. MERCEDES BENZ OF NORTH AMERICA NEEDS TO ADDRESS THIS SITUATION BEFORE IT BECOMES A FATAL MISHAP. THE SOUND AND GLASS DEBRIS COULD HAVE EASILY DISTRACTED ME ENOUGH FOR ME TO LOSE CONTROL OF THE VEHICLE AND CAUSE AN ACCIDENT. LUCKILY NO ONE WAS NEAR OUR CAR.
