FUEL/PROPULSION SYSTEM
Fuel line malfunctioned, car stopped , gasoline was pouring out from under the hood. I was "lucky" that it did not catch fire, fire department showed up, closed the street, car was towed, dealership " replaced high-pressure line of fuel system high pressure pump". It all started without a warning, suddenly after about 1 month of driving ( 1000 miles) a brand new Mercedes GLC300.

AIR BAGS
The contact owns a 2020 Mercedes-Benz GLC300. The contact stated that upon driving through an intersection at 40 mph, another vehicle had run a stoplight. The contact swerved in an attempted to avoid the vehicle, however, she had hit the vehicle's rear driver side tire weld. The contact stated that the driver-side airbag did not deploy upon impact; however, the passenger-side airbag, where her mother was seated, did deploy. The Mercedes-Me app automatically called 911 and the contact initially declined medical attention at the time. A police report was filed. Due to the failure, the vehicle was towed to an independent mechanic. The next day, the contact was referred by her doctor to a hospital where they performed a cat scan and x-ray. The contact tested positive for Covid-19 the following Monday and believed it was as a result of the hospital visit. The manufacturer was notified of the failure and upon her own research, the contact discovered NHTSA Campaign Number: 21V354000(BACK OVER PREVENTION, ELECTRICAL SYSTEM). The vehicle remained in the possession of the independent mechanic and had yet to be repaired. The failure mileage was unknown.

What component or system failed or malfunctioned, and is it available for inspection upon request? Car is at Mercedes dealer for repair. How was your safety or the safety of others put at risk? Yes, car lost acceleration on freeway and put other drivers at risk on the road. Lucky to get off freeway and pull over without any injuries. Has the problem been reproduced or confirmed by a dealer or independent service center? Dealer provided feedback cracked piston, cylinder # 2. Reading on forums, others continue to have the same issue. Has the vehicle or component been inspected by the manufacturer, police, insurance representatives or others? Inspected by Mercedes bens manufacturer. Were there any warning lamps, messages or other symptoms of the problem prior to the failure, and when did they first appear? in retrospect, some slow acceleration delays 1-2 days prior, but not consistent.

ENGINE
AT 40,000 MILES, ONE OF THE WRIST PINS SNAPPED AND THE PISTON BROKE OFF. THIS CAUSED COMPLETE ENGINE FAILURE AND THE WHOLE ENGINE NEEDS TO BE REPLACED. THIS IS THE SAME PROBLEM THAT CAUSED A RECALL WITH THE 2015 MODEL. THE DEALERSHIP IS MAKING ME PAY FOR THE LABOR, BUT MERCEDES DONATED THE ENGINE (PROBABLY BECAUSE THEY KNOW IT'S THEIR FAULT). SO I'M WONDERING IF THERE SHOULD BE A RECALL ON THIS MODEL AS WELL.

FUEL/PROPULSION SYSTEM
WHILE DRIVING, THE MALFUNCTION INDICATOR LAMP (MIL/CHECK ENGINE LIGHT) CAME ON. AFTER SOME DIGGING THIS WAS CAUSED BY AN OBD II CODE OF P052E, WHICH INDICATES A BLOCKED CRANKCASE VENT VALVE ACTUATOR. THIS APPEARS TO BE A MANUFACTURING DEFECT IN THESE VEHICLES.

THE SUNROOF OF OUR CAR SHATTERED BY ITSELF WHEN WE WERE DRIVING ON A CITY STREET. THERE WAS NO PROJECTILE THAT CAUSED THE SUNROOF TO SHATTER AND THE DEALERSHIP WAS ABLE TO CONFIRM THAT. BUT THE DEALERSHIP AND THE COMPANY ARE UNABLE TO SAY FOR CERTAIN WHY THIS HAPPENED AND WHETHER OR NOT THIS WILL HAPPEN AGAIN. THE INCIDENT CAUSED GLASS TO FALL ON ALL OUR PASSENGERS AND THE SOUND OF THE GLASS SHATTERING DURING DRIVING REALLY SCARED US. WE ARE CONCERNED FOR OUR SAFETY AND EVEN MORE CONCERNED THAT MERCEDES IS UNABLE TO DIAGNOSE WHY THIS HAPPENED AND ARE NOT ABLE TO SAY FOR SURE THAT IT WOULD NOT HAPPEN AGAIN.

ENGINE, FUEL/PROPULSION SYSTEM
ON APRIL 21, 2021 AT ABOUT 1800 (TIME), LESS THAN 45-HOURS AFTER PURCHASE OF THE NEW 2021 GLC 300 VEHICLE, THE INTERNAL COMBUSTION (ENGINE) MISFIRED AND ABRUPTLY MALFUNCTIONED WHILE IN STEADY ACCELERATION AT 65-MPH. MY FAMILY AND I WERE HEADED EASTBOUND ON THE CA-60 FREEWAY IN LANE THREE (LEFTMOST, FASTEST LANE). AS SOON AS THE ENGINE SPONTANEOUSLY SPUTTERED, IT ABRUPTLY STOPPED AND INTENSELY SHOOK THE ENTIRE CAR VIGOROUSLY, AGGRESSIVELY, AND CONTINUOUSLY WITH NO ABILITY FOR CONTROL NOR FOR THE OPTION TO CONTINUE TO ACCELERATE. THERE WERE THREE CARS BEHIND MY VEHICLE ALSO ACCELERATING AT THE SPEED OF TRAFFIC (65-MPH) THAT ALSO ABRUPTLY SCREECHED TO A HALT TO STEER CLEAR OF MY UNUSUALLY MALFUNCTIONING VEHICLE. THIS WAS THE MOST TRAUMATIC EVENT THAT HAS EVER HAPPENED TO MYSELF AND MY FAMILY IN OUR LIFETIME. AS YOU CAN IMAGINE, WE FEEL EXTREMELY FORTUNATE IN HAVING SURVIVED THIS HORRENDOUS, UNEXPECTED, AND CRUEL SAFETY RISK AS NO COLLISION WAS FORTUNATELY REPORTABLE. THE VEHICLE'S MALFUNCTIONING AND PERFORMANCE ISSUE HAD PLACED US IN AN EXTREMELY HIGH-RISK OF SAFETY CONCERNS AND NEAR MOMENTS FROM MY OR MY FAMILY'S HEALTH-RELATED TRAGEDY AS THE HALT OF NUMEROUS CARS WITHIN THE FREEWAY CLOSELY SWERVED-AWAY FROM OUR DIRECTION. AS YOU CAN IMAGINE, WE ARE SEVERELY, PHYSICALLY, EMOTIONALLY, AND MENTALLY DISTRAUGHT DUE TO THE MANUFACTURING DEFECT TO THE 2021 GLC 300 ENGINE. AFTER 30-HOURS OF CONTINUED QUESTIONING, ANALYSIS AND DISCOVERY, IT WAS CONFIRMED OF VALVE TRAIN COMPONENT DEFECT CAUSING MAJOR DOWNSTREAM EFFECTS TO THE ENGINE AND IMMEDIATE INABILITY TO ACCELERATE ON THE HIGHWAY WITH DIRECT SERIOUS LIFE THREATENING RISK TO A NEW VEHICLE AND MY FAMILY WITHIN IT. PLEASE CONSIDER THIS DETRIMENTAL INCIDENT FOR OTHER'S GLOBAL SAFETY THROUGH MY TRAGIC EXPERIENCE.

VEHICLE SPEED CONTROL, UNKNOWN OR OTHER
I WAS DRIVING AND STOPPED CAR TO MAKE A TURN WAITING FOR INCOMING TRAFFIC TO CLEAR. WHEN I WENT TO ACCELERATE AFTER TRAFFIC CLEARED, THE CAR WOULD NOT GO ABOVE 0.5 MILES PER HOUR. I MADE SURE THE GEAR HAD NOT SHIFTED TO NEUTRAL, IT WAS ON COMFORT DRIVE. I CHANGED TO SPORTS DRIVE AND THE CAR STILL WOULD NOT ACCELERATE ABOVE 0.5 MILES. I WAS NOW STUCK IN THE MIDDLE OF INTERSECTION WITH INCOMING TRAFFIC, SO I TRIED TO REVERSE. THE CAR REVERSED NO FASTER THAN 0.5 MILES PER HOUR. I TURNED CAR OFF AND BACK ON, AND ACCELERATION THEN WORKED. VERY SCARY. I WAS LUCKY INCOMING TRAFFIC AVOIDED ME. BIG SAFETY HAZARD. DEALERSHIP SO FAR HAS NOT BEEN ABLE TO REPLICATE THE ISSUE, BUT I READ OTHER BLOGS WHERE PEOPLE EXPERIENCED A SIMILAR EVENT.

I WAS ON MY WAY TO JURY DUTY WHEN THE SENSOR WHICH REGULATES ACCELERATION WENT OUT. THIS NEARLY PREVENTED THE SAFE DRIVING, SPEED CONTROL AND ACCELERATION OF THE VEHICLE. I WAS TRYING TO ENTER THE FREEWAY ON ONE OF THE BUSIEST FREEWAYS IN THE AREA OF PEARLAND, TX. I WAS SO FRANTIC, I BEGAN TO CRY AND PRAYED TO REACH THE EXIT NEAREST MY HOME AND IMMEDIATELY PULLED INTO THE GOODYEAR AUTO CENTER. I PAID FOR THE REPAIR OUT- OF-POCKET BECAUSE I HAD NO CHOICE. THE VEHICLE WAS UNSAFE TO DRIVE, THE NEAREST MB DEALERSHIP IS APPROXIMATELY 20 MILES AWAY.

STRUCTURE:BODY, ENGINE
I HAVE PURCHASED THE 2021 MERCEDES-BENZ GLC 300 4MATIC COUPE AND NOTICED A DESIGN FLAW ON THE CAR. AS YOU CAN SEE IN THE ATTACHED PICTURE, THE FRONT BUMPER PROVIDES NO PROTECTION TO THE RADIATOR. IT HAS ALREADY STARTED CHIPPING DUE TO THE ROCK DAMAGE. THIS CAN LEAVE THE CAR IMPAIRED ON THE FREEWAY WHICH CAN BE DANGEROUS. I DID CONTACT THE DEALER AND THEY SAID THERE IS NOTHING THEY CAN DO.

THERE IS AN EXISTING ISSUE FOR MERCEDES-BENZ VEHICLES. SERVICE CAMPAIGN #2019040010. HOWEVER, IT ONLY INCLUDES 2019 MODELS. I PURCHASED A 2021 GLC MODEL AND IT HAS THE SAME ISSUE OF NOT HAVING THE PROTECTION ON FRONT RADIATOR. LOOKS LIKE MERCEDES-BENZ DIDNT DO ANYTHING ABOUT THIS ISSUE AND KEPT MAKING VEHICLES WITH THE SAME DEFECT.
