TIRES

4 complaints

We were traveling home and our TPMS indicated a tire failure. The PSI starting dropping rapidly. We took the tire off and found that only 4 " of rubber holding the back sidewall together on the tire. I then inspected the other tires on the car (which were purchased and installed at the same time) are showing signs of failure as well. All of the tires are 255-40-r19 We had a family of 4 in the vehicle at the time of the incident.

I PURCHASED 4 NEW 255/45/ZR18 EXTREMECONTACT DWS ABOUT 13 MONTHS AGO AND NOW ALL 4 TIRES HAVE A BULGING BUBBLE ON THE SIDEWALLS. OF COURSE I BROUGHT IT BACK FROM WHERE I PURCHASED IT FROM AND THEY BLAME IT ON POT HOLES, ROAD HAZARDS. I CURRENTLY CANNOT DRIVE THE VEHICLE IN FEAR THAT I MIGHT HAVE A BLOW OUT. I HAVE PURCHASED MANY TIRES BEFORE THAT WERE NOT CONTINENTAL AND NEVER EXPERIENCED WHAT IM GOING THROUGH NOW. LET SEE HOW LONG IT WILL TAKE TO BE CONTACTED WITH SOME HELP OR WHAT EXCUSE THEY GOING TO COME UP WITH. *TR

MICHELIN PILOT SPORT A/S PLUS 255/45ZR18 99Y AS+ INSTALLED ON 2008 MERCEDES S550. TIRES TREAD IS "CHUNKING" WITH 18,000 MILES OF USE. PURCHASED FROM COSTCO. I HAVE CONTACTED COSTCO. WAS TOLD IT WAS "NORMAL", COMPLAINED IT CANNOT BE, WE NEGOTIATED BACK AND FORTH ON AN ADJUSTMENT. IT WASN'T SATISFACTORY. I WAS OFFERED FOR A DISCOUNT PRICE THE "NEW" VERSION OF THE TIRE, I.E. PILOT SPORT A/S 3. I HAVE READ THE OTHER COMPLAINTS ON NHTSA SITE. THEY ARE SIMILAR TO MINE. I SPOKE TO 4 DIFFERENT COSTCO EMPLOYEES, THREE DIFFERENT MICHELIN YET, I COULD NOT FINE ANYONE AT COSTCO OR MICHELIN THAT CAN ASSURE ME WITH AN OFFICIAL MICHELIN STATEMENT THE PROBLEM HAS BEEN CORRECTED WITH THE NEW PILOT SPORT 3. I WILL NOT PAY TO HAVE NEW TIRES INSTALLED AT A DISCOUNT AND HAVE THE SAME THING HAPPEN AGAIN.THESE TIRES ARE A POTENTIAL SAFETY HAZARD. *TR

THE TIRE TREAD ON THE MICHELIN PILOT SPORT A/S PLUS SHREDS OR CRUMBLES. MICHELIN CALLS IT "CHUNKING" AND SAID IT WAS DUE TO THE COMPOUND USED TO MAKE THE TIRE. THE COMPOUND HAS SINCE BEEN MODIFIED. THIS PROBLEM OCCURRED ON MY GIRL FRIEND'S 2009 MERCEDES C-SERIES SEDAN AND ALL FOUR TIRES WERE REPLACED IN OR ABOUT NOVEMBER 2012. I NOTICED THE SAME PROBLEM OCCURRING TO THE FRONT TIRES ON MY MERCEDES S550 AT JUST OVER 24,000 MILES OF USE. THE TIRE HAS A 45,000 TREAD-WEAR WARRANTY. THE TIRES WERE PURCHASED IN NOVEMBER 2010. THE MICHELIN DEALER AND MICHELIN ACKNOWLEDGE THIS IS A KNOWN PROBLEM. THE TREAD SPLITS OR CRACKS AT THE SIPES AND FALLS OFF, AFFECTING TRACTION AND POSSIBLY RISKING A CATASTROPHIC FAILURE. MICHELIN SAID THE PROBLEM OCCURS ON ONLY CERTAIN MODEL VEHICLES AND DOES NOT INTEND A RECALL. THESE TIRES WERE RECOMMENDED BY MICHELIN FOR MY VEHICLE, BUT IT APPEARS THEY MAY NO LONGER RECOMMEND IT. THEY NO LONGER RECOMMEND OR MAKE THEM FOR MY GIRL FRIEND'S VEHICLE. *TR

ENGINE

2 complaints

I’m reporting a serious safety issue with the balance shaft sprocket in my Mercedes-Benz S550 (M273 engine, 273.968). This is a known defect that causes the sprocket to wear out far too early due to poor material design. When it wears, it throws off the engine timing, leading to check engine lights, rough idling, reduced power, and even stalling. In some cases, the engine can shut down while driving, which is a major safety risk. Thousands of people have experienced this exact problem, and it’s all over Mercedes forums, Reddit, and technical bulletins. Mercedes quietly updated the part in later models, which shows they knew the early ones were defective. Some people got repairs under warranty or “goodwill,” but most of us are stuck with thousands in repair bills for something that clearly shouldn’t have failed. This isn’t just a mechanical issue—it’s a safety concern. Imagine merging onto a highway or turning through an intersection when the engine loses power. That’s a real risk with this defect. Mercedes should be held accountable, and NHTSA needs to investigate and push for a recall before someone gets hurt or worse.

May 07, 2025

THE ENGINE HYRDO LOCKED AT 66000 MILES AND FAILED A PISTON ROD ACCORDING TO MERCEDES. CAR WAS MAINTAINED AND SHOWED NO ABNORMAL FUNCTIONALITY, JUST PRIOR TO INCIDENT AT HIGHWAY SPEED. ENGINE LOCKED UP. THIS APPEARS TO BE A COMMON PROBLEM WITH THIS CAR AND COULD BE ASSOCIATED WITH FAILED HEAD BOLT STUD.

FUEL/PROPULSION SYSTEM

2 complaints

About 2 to 3 weeks ago I suddenly started smelling faint gas outside the vehicle on the driver side. Over 2 weeks it got stronger and finally I was able to smell it inside and immediately investigated. I discovered the fuel filter underneath the rear seat behind the driver was leaking and the foam under the seat was soaked in gasoline. I did not find my vehicle to be in recall for this safety issue. However, I did find recall 12V-557 for other models that have similar issues with a defective fuel filter. I believe my vehicle should be covered by this recall. I resolved this issue by visiting the dealership and after being told my vehicle was not under recall, I purchased the fuel filter myself from the parts department and replaced it. Included are 2 pictures. One showing crack in the filter that cause gasoline to spray against a cover and leak into the vehicle. And a second picture taken showing the fuel filter soaked in gasoline prior to its removal.

Aug 15, 2024

MY VEHICLE HAS A STRONG GAS ODOR WHILE DRIVING BUT PARTICULARLY WHEN THE VEHICLE IS STATIC OR PARKED. THIS SMELL IS SO STRONG THAT I CANNOT SIT IN THE CAR AND MY CLOTHES REAK OF THE SMELL. THERE HAS NOT BEEN ANY EXTERNAL GAS LEAKAGE OR PERFORMANCE ISSUES WITH THE CAR. ONLY THE GAS ORDOR THAT HAS GIVEN ME A HEADACHE AND MAKES ME NAUSEATED. THE CAR ONLY HAS 70,000 MILES ON IT.

SUNROOF DON'T WANT TO CLOSE. NEED TO BE REPLACED BY DEALER

Oct 26, 2020

MERCEDES BENZ, S550, 4MATIC, 2008. I WAS STOPPED AT A RED LIGHT. WHEN THE LIGHT TURNED GREEN AND I WAS MOVING FORWARD AT ABOUT 15-20 MILES PER HOUR, THE CAR CAME TO A SUDDEN STOP. THE VEHICLE BEHIND ME ALMOST RAN INTO MY BACK SINCE THERE WERE NO BRAKE LIGHTS ILLUMINATED WHEN THIS UNFORTUNATE MALFUNCTION TOOK PLACE. I IMMEDIATELY LOOKED THE CONTROL PANEL FOR ANY MALFUNCTION ALARM AND THERE WERE NONE. THE ROOT CAUSE OF THE PROBLEM WAS FRONT DIFFERENTIAL SEIZE UP WITHOUT ANY WARNING. THERE WERE THE RIGHT AMOUNT OF OIL IN THE RESERVOIR SO THE PROBLEM WAS NO DUE TO LACK OF LUBRICATION. THE CAR WAS REPAIRED BY MB DEALER AND I WAS GIVEN A BILL FOR (HOLD ON TO YOUR PANTS) $8,252. I CALLED MB CUSTOMER SERVICE TO FIND OUT IF THERE ARE ANY RECALL ON THIS MALFUNCTION. I WAS TOLD NONE REPORTED. I HAVE A HARD TIME BELIEVING THAT I AM THE ONLY ONE WITH THIS PROBLEM. I ALMOST CAME TO A DECISION TO SIGN OVER THE TITLE AND HAVE THEM SELL THE CAR TO RECOVER THE REPAIR COST. OBVIOUSLY THE DEALER IS NOT AT FAULT HERE. HOWEVER YOU WOULD EXPECT THAT A CAR OF THIS CALIBER WOULD BE BETTER DESIGNED AND SUPPORTED. AS YOU HAVE GUESSED I AM UNHAPPY WITH MY MB. BY THE WAY IF YOU ARE TRYING TO SIGN ON FOR MB ONLINE OWNER COMMUNITY AND WANT TO CHOOSE THE USERNAME "UNHAPPY", YOU CAN'T. IT IS ALREADY TAKEN. TRY IT WITH SOME #S. *TR

I GOT A BLOW OUT IN THE REAR LEFT SIDE TIRE. I WAS DOING ABOUT 40 MPH AND DID NOT GO OVER ANYTHING THAT I WAS AWARE OF. I WENT TO CHANGE THE TIRE USING THE SUPPLIED TIRE AND JACK. THE JACK WAS VERY FLIMSY AND AFTER I RAISED THE VEHICLE THE JACK FLIPPED OVER CAUSING DAMAGE TO MY CAR, HOWEVER I NARROWLY AVOIDED PERSONAL INJURY. THERE IS A PLATE UNDER THE VEHICLE AT THE JACK CONTACT POINT WHICH ALSO BROKE OFF THE VEHICLE WHEN THE JACK ROLLED OVER. THE FOLLOWING ARE THE DEFECTS I BELIEVE EXIST. 1. THE JACK IS EXTREMELY FLIMSY AND IS DIFFICULT TO SET PROPERLY ON THE GROUND. 2.THE JACK PLATE ON THE CAR APPARENTLY IS ALSO NOT VERY STABLE. 3. THE HANDLE ON THE JACK IS VERY SHORT AND REQUIRES AN EXTREME AMOUNT OF STRENGTH TO LIFT CAR. (NO LEVERAGE) 4. THE LUG WRENCH IS ALSO VERY SHORT AND REQUIRES A LOT OF STRENGTH TO LOOSEN BOLTS, THERE IS ABSOLUTELY NO LEVERAGE. I ESTIMATE THE DAMAGE TO MY VEHICLE, WHICH I BLAME ON THE DEFECTIVE JACK TO BE ABOUT $750.00. *TR
