The windshield cracks and spreads rapidly without any evidential cause for a crack and yes it would be available for inspection upon request. This is the 5th replacement in 5 years - 2 in one year alone: 1st - At the time of purchase with only 16555 miles (MPI) RBM replaced the windshield. 2nd - 1/21/20 - 40410 miles (Just got home from a drive through car wash and noticed the crack). 3rd - 7/24/20 - 42150 miles. 4th - 8/26/22 - 62274 miles. 5th - 6/18/23 - 77172 miles. Safety was at risk due to nervousness as to what could ultimately happen affecting driving ability. The problem has reproduced itself 5 times. RBM has refused to take responsibility and consistently escalates replacement cost. No warnings or causes leading to cracks/breakage

My 2015 S550 front stationary sunroof glass panel coating is fading.
Dec 11, 2023
I am writing to report an incident that occurred on Oct 17 2023 involving my 2015 Mercedes Benz S550, where the front portion of the two-part sunroof spontaneously exploded while I was driving down the highway. On the aforementioned date, at approximately 5 pm, I was traveling down Beltway 8 In Houston in my Mercedes Benz S550 along with a pack of cars. Suddenly, without any warning signs or external impact, my vehicle experienced a violent shaking accompanied by an extremely loud popping sound, reminiscent of a gunshot. The intensity of the event startled me, and I quickly maneuvered my car to safety while other drivers also reacted to the sudden disturbance on the road. Once I pulled over and inspected the damage, I was horrified to discover that the front portion of the two-part sunroof had completely shattered, leaving a significant hole and glass fragments both inside and outside the vehicle. The explosion occurred on the Beltway, before the Kirby exit. Fortunately, I escaped any injury as the glass fragments were ejected upwards due to the force of the explosion. It is important to highlight the potential devastation that could have occurred had I kept the screen under the sunroof rolled in, as is my usual practice. Considering the size and force of the explosion, it is reasonable to imagine that if the glass had come pouring down onto my head and body, it could have caused severe injuries, including lacerations, contusions, and possibly even more serious harm. In light of this incident, I am deeply concerned about the safety implications for myself and other vehicle owners who may encounter similar issues with the sunroof in their Mercedes Benz S550 or other models. It is crucial that this matter be thoroughly investigated to determine the underlying cause and prevent any potential risks or harm to future drivers.

The panoramic sunroof on my 2015 Mercedes’ Benz S550 e has malfunctioned in the closed position. The sunroof could detach and fly off the car during operation. The dealer has inspected and identified the problem. There was no warning sign before the sunroof failed.

The gear selector on the steering wheel of the Mercedes Benz has a park button on it when you change the car from gear to park you press that button. That part button has stopped working. It is a safety risk as the car cannot be parked at the end of the driving and it stays in the drive mode. I have to open the door to activate the parking which is built in to the car

THE RIMS ON THE CAR CRACKING. I REPLACED THE RIMS IN THE TWO FRONT WHEELS AND NOW THE RIGHT REAR RIM IS CRACKED, I HAVE REPORTED THIS PREVIOUSLY TO YOUR COMMISSION INCLUDING SENDING PICTURES. THE DEALER DOES NOT WANT TO ACCEPT RESPONSIBILITY. IN THE FUTURE PROBABLY THE 4TH WHEEL RIM WILL HAVE THE SAME FATE.

ON 10,2018 I NOTICED LOSS OF AIR PRESSURE ON THE LEFT FRONT TIRE. AFTER INFLATING THE TIRE TWICE, I BROUGHT THE CAR TO AN AUTHORIZED DEALER WHO TOLD ME THAT THERE IS A CRACK ON THE RIM. AFTER 5 DAY'S THE RIM WAS REPLACED WITH A NEW ONE. THE EXPLANATION GIVEN TO ME WAS THAT I HIT A POT HOLE. THIS PAST WEEK THE SAME HAPPENED ON THE RIGHT FRONT WHEEL, GIVING ME THE SAME EXPLANATION. THIS TIME I TOOK PICTURE OF THE RIM AND NOTICED THAT THERE 3 CRACKS IN THE INNER ASPECT OF THE RIM IN A RADIAL FASHION. PERSONALLY I DON'T RECALL BITING A POTHOLE OR ANYTHING ELSE. THE OUTSIDE ASPECT OF THE RIM IS IN EXCELLENT CONDITION. I BELIEVE THIS IS A MANUFACTURING PROBLEM THAT HAS THE POTENTIAL TO CAUSE A MAJOR ACCIDENT WHEN YOU DRIVE ON A HIGHWAY. THE PHOTOS I TOOK WAS WITH MY CELL PHONE BUT UNFORTUNATELY I AM NOT SAVVY ENOUGH TO TRANSFER. HOWEVER, I FIND AN EXPERT TO DOWNLOAD AND MAKE HARD COPIES. *TR *JS

AFTER THE CAR HAD BEEN OPERATED FOR ~20K MILES, IT WAS TIME TO TAKE IT IN FOR TIRE REPLACEMENT. THIS WAS EXPECTED SEEING AS THE STOCK TIRES ARE A SOFT COMPOUND TIRE. WHILE AT THE TIRE SHOP, IT WAS DETERMINED THE FRONT PASSENGER RIM, AND REAR DRIVER SIDE RIM, WE BOTH CRACKED. THE FRONT HAD FOUR CRACKS ON THE INSIDE EDGE OF THE RIM, AND TWO CRACKS ON THE REAR RIM. AFTER DISCUSSING THIS ISSUE WITH MY LOCAL DEALER, HE INFORMED ME THAT MANY CUSTOMERS HAVE COMPLAINED ABOUT SOFT ALUMINUM RIMS INSTALLED ON THE MERCEDES S CLASS. APPARENTLY THESE RIMS ARE EASILY DENTED, CRACKED, OR PUNCTURED, EVEN DURING NORMAL OPERATION ON ROADS WITHOUT POTHOLES. I BELIEVE THESE RIMS ARE A SAFETY HAZARD TO NOT ONLY THE OCCUPANTS OF MY CAR, BUT ALSO TO OTHER DRIVERS ON THE ROAD. APPARENTLY THIS ISSUE HAS COME TO LIGHT IN YEARS PAST; JUST GOOGLE LUPPINO ET AL V. MERCEDES-BENZ USA. MERCEDES NEEDS TO PLACE A RECALL ON THESE RIMS TO ENSURE THE PROPERTY SAFETY OF THEIR VEHICLES ON OUR ROADWAYS.

ON JULY 15, 2020, I WAS INVOLVED IN A ONE CAR ACCIDENT. THE CAR LEFT THE ROADWAY ON A CURVE WHEN I LOST CONSCIOUSNESS DUE TO A MEDICAL ISSUE, AND SLID DOWN AN EMBANKMENT INTO A TREE. THE TREE PREVENTED A TOTAL ROLLOVER AND THE CAR WAS AT A 45 DEGREE ANGLE. I WAS THROWN AGAINST THE DRIVER'S SIDE DOOR AND SUSTAINED INJURIES. THE SIDE AIRBAGS DID NOT DEPLOY, NEITHER DID THE FRONT AIRBAGS. THE CAR WAS TOTALED. THE SIDE AIRBAGS ARE SUPPOSED TO DEPLOY IN A SIDE IMPACT OR ROLLOVER SITUATION, BOTH OF WHICH OCCURRED. BECAUSE THEY DID NOT DEPLOY, I SUFFERED A HEAD INJURY, BROKEN RIBS FROM THE IMPACT, AND LACERATIONS FROM THE BROKEN WINDOW AND TREE. I HAVE ENCLOSED THE POLICE REPORT AND PICTURES. THE REPORT ERRONEOUSLY STATED THE AIRBAGS HAD DEPLOYED, BUT THE PICTURES CLEARLY SHOW THEY DID NOT. I HAVE MORE PICTURES, IF NEEDED.

I bought my S-class car at a Manhattan dealership with 4900 miles on it, I treated it like my baby I’m the only driver and all services and maintenance had been done at the dealership, and I started getting bad readings on the fuel, check engine is ON, fuel gauge reads Full then goes down to Empty The mechanics at the Manhattan dealership said it was short on the fuel tank and I need to have the whole new tank replaced, my understanding is this model, the S Class has been having this issue on many models and there was a soft recall on that matter and it can be fixed at the dealership, we do have a case number with the Dealership. case number 03656172

THIS CAR WAS PURCHASED IN CHARLOTTE NC IN WINTER OF 2018. IN NOVEMBER OF 2019, WHILE DRIVING DOWN THE ROAD WITH NO CARS IN SITE, WE HEARD A LOUD POP. WE COULDN'T FIGURE OUT WHAT THE NOISE WAS BECAUSE IT SOUNDED LIKE A ROCK HIT THE WINDSHIELD BUT WE DIDN'T SEE ANYTHING. WE COULDN'T FIGURE OUT WHERE A ROCK COULD HAVE COME FROM AS THEIR WERE NO CARS ON THE ROAD. THAT AFTERNOON WE PULLED BACK THE ROOF SCREEN TO FIND THAT THE GLASS PANORAMIC ROOF HAD CRACKED ALL OF THE WAY BACK. THE CRACK STARTED IN THE UPPER LEFT CORNER OF THE CAR IN THE CURVE OF THE TOP. THE CRACK STARTED RIGHT WHERE THE WINDSHIELD AND THE ROOF COME TOGETHER. MERCEDES CONVINCED US THAT SOMETHING HAD TO HAVE HIT IT. WE MADE A CLAIM ON OUR INSURANCE AND $10,500 LATER, THE TOP WAS REPLACED. 5 MONTHS LATER AS WE WERE PULLING OUT OF OUR DRIVEWAY ONTO A 2 LANE COUNTRY ROAD, WE HEARD THE SAME NOISE AND AGAIN, PULLED THE SHADE BACK TO SEE THE ROOF HAD CRACKED ONCE MORE. BETWEEN THE TWO INCIDENTS, THE CAR HAS ONLY BEEN DRIVEN 600 MILES. THE CAR IS HARDLY EVER DRIVEN AND STAYS COVERED UP IN A CLIMATE CONTROLLED GARAGE 99% OF THE TIME. NOTHING HAS HIT THE TOP AND BROKEN THE GLASS. THE TOP BROKE IN A WAVY PATTERN JUST LIKE BEFORE. THEIR IS OBVIOUSLY A STRUCTURAL PROBLEM AS THE GLASS IS A STRUCTURAL PART OF THE CAR. THESE ARE OBVIOUSLY STRESS RELATED AND I HAVE SPOKEN TO OTHER OWNERS OF THESE CARS WHO HAVE HAD THE SAME ISSUE AND MERCEDES WILL NOT STAND BEHIND THESE REPAIRS. THEY MAKE YOU BELIEVE YOU ARE IN SOME WAY RESPONSIBLE FOR THIS DEFECT. I CANNOT KEEP FILING AN EXPENSIVE PANORAMIC ROOF REPLACEMENT ON MY INSURANCE, NOW I'M AT THE POINT TO WHERE I'M AFRAID TO DRIVE THE CAR DUE TO THE ROOF POSSIBLY BREAKING. THIS IS UNBELIEVABLE THAT A $150,000 CAR WOULD HAVE THIS SORT OF PROBLEM. *TR

MY WIFE WAS DRIVING MY 2015 MERCEDES BENZ S-550 ON THE 14TH OF AUGUST, 2019. SHE HAD STOPPED AT A RED LIGHT AND WHEN IT TURNED GREEN CROSSED A 6 LANE INTERSECTION. SHE WAS MOVING THROUGH THE INTERSECTION WHEN SHE WAS HIT BY A VW PASSET WHO RAN THE RED LIGHT AT AN ESTIMATED 40 TO 50 MPH. THE PASSET HIT DEAD CENTER ON THE B PILLAR BETWEEN THE DOORS ON THE PASSENGER SIDE OF THE MERCEDES. ALL AIR CURTAINS AND A REAR SEAT AIR BAG DEPLOYED ON THE UNOCCUPIED PASSENGER SIDE OF THE CAR, NONE DEPLOYED TO PROTECT DRIVER'S HEAD ABEAM THE B PILLAR.. MY WIFE'S HEAD WHIPPED VIOLENTLY TO THE RIGHT TOWARDS THE CRASH, THEN WHIPPED BACK VIOLENTLY TO THE LEFT HITTING THE LARGE SEAT BELT RETRACTOR PROTRUSION BUILT INTO THE B-PILLAR. SHE WAS BRIEFLY UNCONSCIOUS AND SUFFERED A SEVERE CONCUSSION AND MAYBE MORE AS MEDICAL TESTS ARE STILL ON GOING. IN ADDITION, SHE SUFFERED 4 HERNIATED DISCS IN HER NECK, 2 SEVERE. SHE ALSO SUFFERED AN ACUTE HERNIATED DISC IN HER LOWER BACK AS WELL AS NOW HAS SOME TMJ ISSUES WITH HER JAW AND HAS TO WEAR A MOUTHPIECE TO SLEEP. NO AIR BAGS OR SIDE AIR CURTAINS DEPLOYED ON THE DRIVERS SIDE OF THE CAR, THAT WOULD HAVE HELPED PROTECT HER HEAD AND LIKELY LESSENED THE SIDE TO SIDE WHIPLASH CAUSING THE HERNIATED DISC ISSUES. WHEN I CALLED MERCEDES BENZ TO INQUIRE WHY NO DRIVERS SIDE AIR CURTAINS OR AIR BAGS DEPLOYED, I RECEIVED A LETTER BACK SAYING THEY WERE NOT DESIGNED TO DEPLOY IN THIS CASE THE CAR, WAS A TOTAL LOSS WITH A $65,000 SETTLEMENT CHECK. MB IS SAYING ONLY THE SIDE CURTAINS ON THE SIDE THE CRASH OCCURRED DEPLOY IN THIS CASE PROTECTING NO ONE. AT THIS HIGH RATE OF SPEED, WITH MB STATING IN A LETTER THAT THE CAR'S AIR BAG PREFORMED AS PROGRAMMED, I THINK THERE IS A MAJOR SAFETY FLAW THAT LIKELY HAS CAUSED OTHER SERIOUS INJURIES OR DEATH.

AFTER WATCHING THE KOREAN OWNER'S PROTEST ON THE SAFETY CONCERN ON THE NEW S63, I FELT THE NEED TO RECALL MY VEHICLE ON THE ECU FILED BY NHTSA ON DECEMBER 6TH. AFTER THE RECALL ON DECEMBER 22ND. I DROVE MY CAR FOR 80MILES. WHENEVER I SLOW THE CAR DOWN FROM TRAFFIC, THE CAR JERKS FOWARD WHEN IT IS DOWNSHIFTING (AUTOMATIC) FROM 4TH GEAR TO 3RD GEAR AND 3RD TO 2ND GEAR. I WENT BACK TO THE DEALER, THEY ASK MY PERMISSION FOR EXTRA 60 MILES OF DIAGNOSTICS BECAUSE THEY THINK THERE IS AN "ADAPTATION" PERIOD FOR THE "MECHANICAL" TO ADAPT TO THE "NEW ECU SOFTWARE RECALL", AND I AGREED AS LONG AS THE CAR CAN BE FIXED. TWO DAYS LATER, DEALER CALLED ME THAT THE TRANSMISSION BROKE (CAN NO LONGER SHIFT AND NOT DRIVABLE WITH ENGINE LIGHTS ON). I REQUEST A REPLACEMENT OF TRANSMISSION SINCE THE CAR IS NEW (LESS THAN 2000 MILES DRIVEN); THEY TOLD ME IT IS NOT POSSIBLE TO REPLACE BUT TO FIX THE TRANSMISSION (CRAKE OPEN MY TRANSMISSION). I CANNOT ACCEPT THE FACT THAT THE NEW ECU UPDATE FILED ON DEC 6TH BROKE MY TRANSMISSION. I CAN NO LONGER TRUST THE MANUFACTURE RECALL BECAUSE IT BREAKS MY NEW VEHICLE. I CAN'T UPLOAD ANY PROVES RIGHT NOW BECAUSE THE DEALER HAS THE HOLD OF MY VEHICLE

AT NIGHT THERE IS A DANGEROUS,VERY DISTRACTING REFLECTION IN THE WINDSHIELD. WHAT IS BEING REFLECTED UPWARD ARE THE LIGHTED DIGITAL TACHOMETER AND SPEEDOMETER. WHEN THE DRIVER IS DRIVING AT NIGHT IN HIS OR HERS FIELD OF VIEW ARE THE DASH GAUGES REFLECTED VIVIDLY IN THE WINDSHIELD GLASS. THIS CONDITION EXISTS IN ALL 2015 S550'S. AND I BELIEVE THAT IT EXISTS ON ALL 2014 S550 PLEASE ADDRESS AS I ALMOST HAVE HAD 3 ACCIDENTS BEING DISTRACTED BY THIS AT NIGHT DRIVING. THANK YOU *TR
