AREA UNDER STEERING COLUMN IS EXPOSED REVEALING ELECTRICAL WIRING WHICH APPEARS TO BE CONNECTED TO THE ENGINE OR SOMETHING UNDER THE HOOD. I WAS TOLD THAT'S THE WAY VEHICLE WAS MADE, NO PART OR OPTION TO COVER EXPOSED AREA. IT IS UNSAFE BECAUSE AS I AM DRIVING ON HIGHWAY, CITY STREETS, ETC., MY KNEES TOUCH THE AREA AND MAY JARR SOMETHING LOSE.

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.

I SMELLED FUEL IN MY GARAGE OCCASIONALLY FOR THE PAST 4 MONTHS. I ASSUMED IN WAS THE GAS HEATER BUT WHEN I PARK MY CAR IN OTHERS GARAGE I SMELLED FUEL. A FRIEND SUGGESTED IT MIGHT BE MY CAR. I TOOK MY CAR INTO SERVICE FOR MY 50K SERVICE AND ASKED IF THEY COULD LOOK INTO. MERCEDES BENZ INFORMED ME IT IS WET AROUND THE FUEL HOSE CONNECTOR. BEFORE I ONLY SMELLED IT TWICE A MONTH IN THE GARAGE. AFTER ONE I GOT IT BACK FROM SERVICE, I SMELLED FUEL INSIDE THE CAR WHILE I'M DRIVING.
Suspension, May 6, 2019
THE FRONT DRIVERS SIDE SUSPENSION SQUEAKS WHEN WHEEL IS TURNED OR GOING OVER BUMPS. THIS CAR IS LESS THAN 5 YEARS OLD AND AROUND 50K MILES. I AM HOPEFUL THIS IS NOT A DANGEROUS FLAW IN THE SUSPENSION SYSTEM.

MY CAR RECEIVED THE CALL MESSAGE OF POTENTIAL AIRBAG HAZARD IN JANUARY, WHICH WOULD LEAD TO DEATH IF THE AIRBAG POPPED UP. HOWEVER, I HAVE NOT BEEN REPLACED IN BANZ STORE FOR FOUR MONTHSIF THERE IS A SUDDEN ACCIDENT, THE AIRBAG WILL POP UP AND KILL PEOPLE. I WOULD LIKE TO COMPLAIN ABOUT SUCH A SERVICE. A DELAY OF ONE DAY IS VERY LIKELY TO CAUSE AN ACCIDENT

AT COLD START, ESPECIALLY WHEN THE HEATER IS ON, THE CABIN SMELLS OF RAW GASOLINE. THE ISSUE IS QUITE ANNOYING AND EXTREMELY DANGEROUS. AFTER PERFORMING A GOOGLE SEARCH ABOUT THE PROBLEM, I'VE NOTICED THAT OTHERS WHO OWN W205 HAVE EXPERIENCED THIS PROBLEM. THIS IS JUST ONE EXAMPLE OTHERS' COMPLAINTS: HTTP://M.CARCOMPLAINTS.COM/MERCEDES-BENZ/METRIS/2016/FUEL_SYSTEM/FUEL_PROPULSION_SYSTEM.SHTML

ENGINE BROKE A PISTON AT 53,000 MILES IN NORMAL USE. CAUSING MAJOR RUPTURE ON ENGINE.

WHEN ACCELERATING WITH MY MERCEDES C300, THE CAR IS ACTUALLY LOOSING POWER. THE EFFECT IS REINFORCED AS THE CONTROLLING SYSTEM IS BLOCKING THE ACCELERATION. RESULT IS THAT THE CAR IS BRAKING SUDDENLY INSTEAD OF ACCELERATING. IT IS PARTICULARLY DANGEROUS WHEN TRYING TO PASS ANOTHER CAR ON THE HIGH WAY AS THE CAR WILL BRAKE. I ALMOST EXPERIENCED TWICE AN ACCIDENT ON THE HIGHWAY DUE TO THIS ACCELERATION/BAKE ISSUE. I BROUGHT MY CAR TO AN INDEPENDENT MERCEDES REPAIR CENTER. THEY CONFIRMED TO ME THAT MERCEDES ISSUED A TECHNICAL BULLETIN FOR AN ELECTRICAL CABLE REPLACEMENT DUE TO THAT FAILURE. THE ISSUE DESCRIBED ON THE TB IS IDENTICAL TO THE EXPERIENCE ISSUE. I CONTACTED MY MERCEDES DEALERSHIP SERVICE DEPARTMENT. THEY INFORMED ME THERE IS NO RECALL AND DON'T CONSIDER THIS ISSUE A SAFETY ISSUE. THEY WON'T REPLACE THE ELECTRICAL CABLE UNLESS I PAID FOR THE "SERVICE". THE CABLE HAS NOT BEEN DAMAGED OR DISCONNECTED. IT IS SIMPLY FAULTY AND MERCEDES KNOWS THE ISSUE AS THEY ISSUED A TB FOR THE VEHICLE.

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.

PANORAMIC SUNROOF SPONTANEOUSLY EXPLODED WHILE THE CAR WAS SITTING. MERCEDES CLAIMING SOMETHING FELL INTO IT, BUT THERE WAS NOTHING ABOVE IT OR IN THE CAR WHILE IT WAS SITTING IN THE GARAGE. AFTER READING ONLINE, THIS IS HAPPENING TO A LOT OF OTHER CONSUMERS, INCLUDING ONE WHO HAS STARTED A CLASS ACTION LAWSUIT IN CALIFORNIA

MERCEDES BENZ WONT HONOR THE RECALLS. VEHICLE WAS IMPORTED (NOT BY ME) FROM CANADA. MERCEDES BENZ CONSIDERS THIS VEHICLE TO BE "GRAY MARKET VEHICLE" AND WONT SERVICE THE VEHICLE FOR RECALLS. THERE ARE UP TO EIGHT (8) SAFETY RECALLS AND THEY MAKE THE VEHICLE UNSAFE TO DRIVE. VEHICLE STILL UNDER FACTORY WARRANTY. I HAVE CONTACTED THE BUREAU OF AUTOMOTIVE REPAIR, WHO REFERRED ME TO THE NEW MOTOR VEHICLE BOARD WHO REFERRED ME TO THE NHTSA. THANK YOU FOR YOUR ATTENTION TO THIS MATTER,
