The panoramic sunroof does not properly seal to car, allowing the glass to detach and fall from the vehicle during operation and likely to impair the operator during use. Furthermore, without properly sealing the internal cabin is exposed to the environment (i.e. rain, snow, ect.) causing further damage to the internal safety and electrical features.

Panoramic sunroof exploded spontaneously while driving. There was no previous warning. Glass shattered onto driver and passenger. The loud sound and glass shattering onto us could have caused self injury or accident to occur. Auto insurance was notified at time of incident. Vehicle was taken to Mercedes benz dealership for repair.

A STRONG FUEL ODOR COMING FROM THE CAR, WE TRIED TO GET THE DEALER TO REPAIR IT UNDER WARRANTY AND THEY SAID, OVER FUELING WAS CAUSING IT, HOWEVER WITH THE TANK HALF FULL IT DOES STILL SMELL A LOT LIKE GAS, A STRONG ODOR YOU CAN SMELL IT OUTSIDE, THEY DON'T WANT TO TAKE RESPONSIBILITY ON IT, AFTER WARRANTY EXPIRED THEY CAME UP SAYING SOMETHING IS WRONG WITH MY FUEL SYSTEM THAT NEEDS TO BE REPAIRED BUT ITS NOT COVERED BY WARRANTY, THERE ARE A LOT OF COMPLAINTS BUT THEY WANT PEOPLE TO PAY FOR THIS, WE ARE AFRAID THIS COULD START A FIRE WHILE DRIVING, OR EVEN WORSE BURN MY HOUSE DOWN

TALK TO DEALER VEHICLE HAS FUEL LINE LEAK NOT COVERED UNDER WARRANTY JUST PURCHASED VEHICLE WITHIN 30 DAYS OF NOTICING THIS ISSUE AND I BELIEVE IT SHOULD BE RECALLED SAFETY ISSUES FUEL SMELL AND COULD CAUSE FIRE

NHTSA ODI 11413231

THERE IS A RAW FUEL SMELL INSIDE THE CABIN OF THE CAR WHEN DRIVING. I LOOKED ONLINE AND FOUND THAT THERE IS A LAWSUIT AGAINST MERCEDES-BENZ FOR FAULTY FUEL LINES THAT THEY ARE REFUSING TO REPAIR. I AM HAVING THE SAME ISSUES WITH THE FUEL LINES AS COUNTLESS OTHER PEOPLE HAVE WHERE THE RUBBER HOSES ARE FAILING PREMATURELY. I HAVE A 2016 C300 WITH ONLY 37,100 MILES ON IT THAT IS KEPT UP ON AND THE DEALERSHIP IS SAYING THAT THE FUEL LINES ARE TYPICAL WEAR ITEMS AND THAT THE CPO WARRANTY DOES NOT COVER THE REPAIR. THIS IS A SAFETY ISSUE AS IT COULD CAUSE A FIRE AND LEAKING FUEL INTO THE ENVIRONMENT AND FUEL LINES SHOULD NOT NEED TO BE REPLACED ALREADY.

MY 2016 C300 4MATIC, WHICH HAS BEEN SERVICED EXCEPTIONALLY WELL, TURNED 57,000 MILES (7K MILES OUTSIDE OF WARRANTY), HAD THE CHECK ENGINE LIGHT TURN ON. I WENT TO MY MECHANIC, WHO HAS A STATE OF THE ART DIAGNOSTIC UNIT, AND IT WAS DIAGNOSED AS CODE P052E WHICH MEANS THAT THE CRANKCASE VENTILATION REGULATOR VALVE INCLUDING THE FUEL RAIL NEEDS TO BE REPLACED. MERCEDES HAS KNOWN ABOUT THIS BEING A MAJOR PROBLEM AS THEY MODIFIED ONE OF THE PARTS. MY DEALERSHIP QUOTED ME OVER $ 2100.00 TO FIX IT AND DEEMED IT NOT COVERED BY THE EXTENDED WARRANTY. I HAVE GONE ONLINE TO SEVERAL MERCEDES BENZ FORUMS AND HUNDREDS OF PEOPLE HAVE HAD THE SAME THING HAPPEN WITH THIS PART FAILING AROUND 52K MARK. SINCE MERCEDES KNEW ABOUT THIS - ISSUED AN IMPROVED PART TO REPLACE THE DEFECTIVE ONE - NHTSA SHOULD MANDATE A RECALL. THIS IS NOT SOME SIMPLE DYI MATTER. IT IS A COMPLICATED REPAIR CONSUMING MANY HOURS. IT IS WRONG THAT DRIVING THIS, WITH THIS CODE, COULD LITERALLY KILL YOU. I IMPLORE NHTSA TO MANDATE A RECALL BASED ON THE FACTS SPECIFIED HEREIN. BY THE WAY I HAVE A 1999 ML320 THAT I HAVE METICULOUSLY MAINTAINED AND DRIVES PERFECT AND I HAVE OWNED MANY OTHER MERCEDES BENZ. I AM 58 YEARS OLD AND I HAVE NEVER FILED A COMPLAINT WITH NHTSA BEFORE. THIS IS A VERY SERIOUS MATTER. PLEASE HELP

RECURRING ISSUE OF SEVERE PULSATION WHEN BRAKING AT HIGHWAY SPEEDS. PULSATION EXACERBATED BY REPEATED STOPPING (RED LIGHTS) OR SLOWING FROM HIGH SPEEDS (FREEWAY EXIT RAMPS). THE PROBLEM MAKES IT DIFFICULT TO MAINTAIN PROPER CONTROL OF THE VEHICLE AND MAKES IT DIFFICULT TO USE MIRRORS DUE TO SHAKING. I HAVE DRIVEN THE VEHICLE LESS THAN 40,000 MILES AND HAVE NEEDED TO REPLACE THE ROTORS TWICE DUE TO THIS ISSUE.

THE VEHICLE HAS A STRONG GAS SMELL WHEN THE VEHICLE IS IDLING. DEALER CHANGED THE 2 FUEL LINES AND CLAMPS. IT'S COMMON PROBLEM IN W205 C300 CARS. THE CAR WAS UNDER EXTENDED WARRANTY AND THE DEALER REFUSED TO COVER IT UNDER WARRANTY EVEN THOUGH THE CAR HAS 29K MILES. THERE SHOULD BE A RECALL FOR THESE FUEL HOSES. THERE IS A CLASS ACTION INVESTIGATION: HTTPS://WWW.SAUDERSCHELKOPF.COM/INVESTIGATIONS/AUTOMOTIVE/MERCEDES-C300-AND-GLA250-FUEL-SMELL-CLASS-ACTION-INVESTIGATION/ YOU CAN SEE MULTIPLE PEOPLE COMPLAINING ABOUT THE SAME FUEL LINES; - HTTPS://YOUTU.BE/LQZZMGFDQ3O - HTTPS://MBWORLD.ORG/FORUMS/C-CLASS-W205/737303-DEALER-SAYS-FUEL-SMELL-LEAK-W205-2015-C300-BASE.HTML

2016 C300 4MATIC AT ABOUT 50K MILES, CHECK ENGINE LIGHT CAME ON AND THEN AS I WAS DRIVING ON THE FREEWAY THE CAR JUST STOPPED ACCELERATING IN THE MIDDLE OF THE FREEWAY AND HAD TO TAKE MY CAR TO THE SIDE AND TOWED IT TO THE DEALER IN WEST COVINA. LUCKILY THERE WAS NO ONE ON THE FREEWAY SINCE IT WAS EARLY SUNDAY MORNING. DEALER IS NOW SAYING THE CAR MIGHT NEED ENGINE REPLACEMENT WHICH WILL COST ME $20K BUT THEY WANT $3000 TO DO A TEAR DOWN TO MAKE SURE. OPENED A CASE WITH THEIR CUSTOMER SERVICE BUT THEY SAID THEY CAN'T DO ANYTHING ABOUT IT SINCE THE CAR IS OUT OF WARRANTY. I AM INCREDIBLY UPSET WITH MERCEDES BENZ - I HAVE NOT USED THE CAR THAT MUCH AND MAINTAINED IT MYSELF ACCORDING TO THEIR MAINTENANCE BOOKLETS. I BELIEVE THIS IS AN ENGINE DEFECT PROBLEM THAT MERCEDES NEEDS TO TAKE CARE OF.

WHILE DRIVING ON THE HIGHWAY, I HEARD A LOUD NOISE THAT, ON FIRST IMPRESSION, LED ME TO BELIEVE SOMEONE FIRED A GUNSHOT AT AND STRUCK MY VEHICLE. UPON LOOKING UP, I IMMEDIATELY NOTICED IT WAS NOT A GUNSHOT BUT INSTEAD THE GLASS TO THE FRONT PORTION OF MY PANORAMIC SUNROOF HAD SPONTANEOUSLY SHATTERED AND FLEW COMPLETELY OFF THE VEHICLE. THIS FLYING GLASS FLEW DIRECTLY BACKWARDS AND COULD HAVE POSED A DEADLY RESULT FOR THE NUMEROUS DRIVERS TRAVELING BEHIND ME. THERE WERE NO FLYING OBJECTS OR OTHER DANGEROUS INSTRUMENTS THAT STRUCK THE VEHICLE BUT THE SUNROOF SPONTANEOUSLY, ON ITS OWN, SHATTERED AND COMPLETELY DETACHED FROM THE VEHICLE. UPON SUBSEQUENT ONLINE INVESTIGATION, I LEARNED THIS VERY ISSUE HAS BEEN EXPERIENCED BY OTHER MERCEDES BENZ DRIVERS, WITH THE SUNROOFS SPONTANEOUSLY SHATTERING AND FLYING OFF. DESPITE PURCHASING A EXTENSIVE WARRANTY AT THE TIME OF PURCHASE, BODY WORK, INCLUSIVE OF GLASS REPLACEMENT, IS NOT COVERED. CONSEQUENTLY, I WAS FORCED TO FILE AN AUTO INSURANCE CLAIM, WHICH REQUIRED AN IMMEDIATE $500 DEDUCTIBLE TO BE PAID TO ENABLE THE REPAIR COMPANY TO ORDER THE REPLACEMENT GLASS. THIS REOCCURRING ISSUE MOST CERTAINLY REQUIRES A RECALL FOR VEHICLES CONTAINING THIS PROBLEMATIC SUNROOF. IT IS NOT ONLY A DANGER TO THE DRIVER OF THE VEHICLE, BUT ALSO TO ALL OTHERS TRAVELING ON THE ROAD.

GAS SMELL COMING THROUGH THE VENTS STARTED OFF EVERY NOW AND THEN AND BECAME MORE FREQUENT. PULLED IT IN THE GARAGE AND THE GAS FUMES MADE THE TOTAL GARAGE SMELL. TOOK IT TO THE DEALER AND THEY SAID IT IS FUEL LINE, THAT SITS NEAR THE ENGINE. IT IS IN THE SHOP NOW. AFTER GOOGLING I SEE SEVERAL OTHER PEOPLE HAVE HAD THIS ISSUE WITH THIS CAR. THEY CANNOT TELL ME YET WHAT CAUSED THE PROBLEM, I AM WAITING TO HEAR THAT

NHTSA ODI 11385654

THERE WAS AN ODOR OF FUEL INSIDE THE CABIN. THE VEHICLE WAS TAKEN TO AN INDEPENDENT MECHANIC, AND THE TECHNICIAN INFORMED ME THAT THERE WAS AN STRONG ODOR OF FUEL WHEN HE LIFTED THE HOOD AND ADVISED THE CONTACT TO TAKE THE VEHICLE TO A MERCEDES DEALER BECAUSE HE WAS NOT CERTIFIED TO SERVICE THE VEHICLE.
