My 2006 R-500 is leaning from the (front and back) passenger side, causing the vehicle to be unsecure to drive... It feels like both side tires are TOTALLY FLAT. I'm not a mechanic, but it looks like the AIR SUSPENSION IS MALFUNTION
Feb 02, 2023
YESTERDAY, WHILE PARKED, I NOTICED THE CAR IS LEANING TOWARDS LEFT SIDE. MECHANIC CHECKED AND FOUND THE AIR SPRING BAG WAS LEAKING. ALSO, THE STRUT ON RIGHT GOT SHOT. MANY OWNERS HAVE THE SAME COMPLAINT. I'M SCARED TO TRAVEL WITH MY KIDS AND GRAND KIDS IN THE CAR. THESE CARS MUST BE RECALLED FOR SUSPENSION PROBLEMS.

TL* THE CONTACT OWNS A 2006 MERCEDES-BENZ R350. THE CONTACT STATED THAT THE SUSPENSION FAILED ON THE FRONT PASSENGER SIDE OF THE VEHICLE WHILE PARKED. THE VEHICLE WAS TAKEN TO A DEALER WHERE IT WAS DIAGNOSED THAT THE COMPRESSOR, RELAY, FUSE LINK, AIR SUSPENSION, AND CORE RETURN NEEDED TO BE REPLACED. THE VEHICLE WAS REPAIRED, BUT THE FAILURE RECURRED TWO MORE TIMES. THE MANUFACTURER WAS MADE AWARE OF THE FAILURE. THE FAILURE MILEAGE WAS APPROXIMATELY 50,000.
Aug 03, 2016
EVERYDAY I GET A RED SIGNAL ALERTING ME TO STOP DRIVING, CAR TOO LOW. IT USUALLY OCCURS WHEN INITIALLY TURNING ON THE CAR OR AT THE BEGINNING OF THE DRIVE. THE REAR OF THE CAR IS VISIBLY LOW AND WHEN DRIVING IT IS UNEVEN AND BUMPY. I HAVE SEEN OTHER R350 OWNERS WITH SAME COMPLAINT AND REPEAT COSTS TO FIX ~1200.00 EACH SIDE. NO SUSPENSION RECALLS ON AN APPARENT DEFECT IN MANUFACTURING?

MY ENGINE WARNING LIGHT CAME ON. I WAS TOLD THAT THE STRUT HAD GONE BAD AND THE CAM IN THE ENGINE WENT BAD. I WAS TOLD BY THE DEALERSHIP THAT IS NORMAL IN THE 06 R350 AND THEY ARE NOT SURE WHY IT HASN'T BEEN A RECALL. IM UPSET BECAUSE IM VIEWING YOUR WEBSITE AND OTHER SITES THAT ARE DESIGN FOR OTHER OWNERS WITH THE SAME VEHICLES AND THEY ARE SHOWING THE SAME PROBLEMS.. WHAT WILL IT TAKE TO GET A RECALL ON THIS BEFORE SOMEONE GETS HURT. *TR

MY 2006 R350 HAS A BALANCE SHAFT ISSUE (GOT THE CODES P0016 AND P0017) ON THE SCANNER. IT SEEMS LIKE A MANUFACTURING DEFECT. THERE ARE ONLY 41K MILES ON THE CAR. *TR

BALANCE SHAFT PROBLEM WITH MB R350, 2006 ENGINE W272 65000 MILES DEALER DOESN'T WANT TO TAKE THE CAR IN FOR AN EXCHANGE ARGUING THIS CAR HAS POTENTIAL PROBLEM PROVEN WITH THE AMOUNT OF REPAIR DONE TO THIS KIND OF ENGINE VERY EXPENSIVE TO REPAIR ( 6 TO 7K) MERCEDES SHOULD ASSUME THE COST OF REPAIR AND ISSUE A RECALL FOR ALL M272 AND M273 ENGINES IN USA AND CANADA. *TR
Sep 26, 2011
CHECK ENGINE LIGHT CAME ON. THE VEHICLE FAILED STATE INSPECTION AND WAS TAKEN TO A MERCEDES DEALER FOR DIAGNOSIS. THEY REPORT THAT THERE IS A BALANCE SHIFT PROBLEM THAT WAS RELATED TO WEAR AND TEAR. THE REPAIR COSTS 5,000.00. I FOUND ONLINE THAT THERE IS A CLASS ACTION SUIT REGARDING THIS ISSUE. I BELIEVE MERCEDES IS WELL AWARE THAT THIS ID A DEFECTIVE PART AND WILL NOT RECALL THE VEHICLE DUE TO FINANCIAL RAMIFICATIONS. *TR
Aug 20, 2011
MY 2006 MERCEDES BENZ R350 WAS DIAGNOSED WITH A COUNTER BALANCE SHAFT/GEAR PROBLEM. IT HAS 85000 MILES... WHICH DOESN'T SEEM LIKE A LOT FOR A CAR THAT IS 5 YEARS OLD AND SUPPOSED TO LAST FOREVER. PLUS I HAVE MAINTAINED THE CAR WITH OIL CHANGES, TIRES, ETC AND AM THE ORIGINAL OWNER. I SEE ON LINE THAT THERE IS A CLASS ACTION SUIT PENDING . I BELIEVE A $5000 REPAIR IS WAY TOO MUCH AND THE COMPANY SHOULD TAKE RESPONSIBILITY. *TR

ENGINE
11 complaints
My car has stalled several times, either when I am driving, or when I stop at a traffic light. Rough idling and/or running when stopped at a red light or driving at speeds that wouldn’t normally be an issue. Engine stalling or misfiring, and car sometimes have trouble starting up. Loud rattling or vibrating noises from the engine. The check engine light is turned on. I took it to Mercedes Benz Dealership in Brooklyn, NY and was told it is a Balance Shaft problem, and they told me it could cost me about $9,000.00. Further research informs me that the problem should not be ignored, nor repair put off. Also, that failure of the balance shaft leaves the inner components of the engine unsecured and therefore will ultimately result in damage to the engine if left unchecked. Also, that driving at high speeds for long periods can agitate the problem even further due to the constant vibrations without a proper securing mechanism. As a result, I parked my car for several months, since I cannot afford the amount they quoted. In essence, I cannot even enjoy the car I bought.

TAKATA RECALL. I PURCHASED MY 2006 MERCEDES R350 IN 2016 WITH OVER 100K MILES ON IT. WITH THE ENGINE LIGHT ALREADY ON. I USED A SCANNER TOOL FOR AN ACCURATE DIAGNOSIS. AS IT STATED TWO ISSUES. A CRANK SHAFT SENSOR/ CAM SHAFT SENSOR WAS NEEDED. SO I DECIDED AGAINST MY BETTER JUDGEMENT TO FINALIZE THE PURCHASE ANYWAY. NEEDLESS TO SAY, AFTER I CHANGED THE SENSORS THE PROBLEM STILL REMAINS. AFTER DOING A LOT OF RESEARCH AND SPENT UNNECESSARY MONEY, IT WAS BROUGHT TO MY ATTENTION THAT THE PROBLEM IS IN FACT A FAULTY BALANCE SHAFT INSIDE OF THE ENGINE. DUE TO A MANUFACTURING DEFAULT. THAT WAS COVERED MY MERCEDES IN A RECALL AT ONE POINT BEFORE I HAD PURCHASED THE VEHICLE. FOR SOMETHING AS SERIOUS AS A DEFECTED PART IN A MOTOR SHOULD NOT BE LIMITED TO WHEN YOU PURCHASE THE VEHICLE, BUT WHENEVER IT IS BROUGHT TO THEIR ATTENTION IT SHOULD BE REPAIRED WITHOUT HESITATION SINCE THIS IS A MANUFACTURING DEFAULT AND NOT SOMETHING THAT WAS DONE BY ANY PREVIOUS OWNERS. I WOULD LIKE TO KNOW WHAT IF ANYTHING CAN BE DONE TO HELP ME RESOLVE THIS ISSUE AT HAND. THANKS IN ADVANCE.

BALANCE SHAFT GEAR DEFECTIVE APPARENTLY MERCEDES HAS BEEN AWARE OF THIS PROBLEM, CLASS ACTION SUITS HAVE BEEN FILED- NO RECALL YET. I PLAN TO CALL MERCEDES DEALER TOMORROW- DO NOT ANTICIPATE ANY HELP ON THEIR PART - IF THAT'S THE CASE WILL TRY TO JOIN CLASS ACTION SUIT AS THIS IS A KNOWN AND VERY COSTLY -(THOUSANDS OF DOLLARS) PROBLEM FOR NUMEROUS MB VEHICLES- MANY CLASSES FROM 2007 -2011. MERCEDES BENZ WAS APPARENTLY AWARE OF THIS DEFECT WHEN I PURCHASED MY VEHICLE (USED) FROM LOCAL MB DEALER HERE IN NY 2009 AS A PRE OWNED CERTIFIED VEHICLE, WHY WAS I NOT MADE AWARE OF THIS ISSUE THAT MERCEDES KNOWINGLY KNEW AND COME TO FIND OUT A CLASS ACTION LAWSUIT WAS FILED. THE NHTSA NEED S TO LOOK INTO THIS MANY COMPLAINTS HAVE BEEN FILED, MERCEDES SERVICE TECHS WERE MADE AWARE OF THIS ISSUE BUT THEY WERE NOT INSTRUCTED TO LET CUSTOMERS BE KNOWN OF THIS WHEN CARS WERE BROUGHT IN FOR SERVICE. PLEASE LOOK INTO THIS AND RECALLS MUST BE PREFORMED

THIS IS A WELL DOCUMENTED ISSUE BUT MERCEDES BENZ REFUSES TO ACKNOWLEDGE THE BALANCE SHAFT AS A DEFECT AND ROAD SAFETY HAZARD. UNFORTUNATELY IT'S GOING TO TAKE SOMEONE'S ENGINE FALLING A PART AT HIGH SPEED CAUSING AN ACCIDENT BEFORE SOMEONE WILL DO SOMETHING WHICH IS TERRIBLE. MERCEDES-BENZ BALANCE SHAFT PROBLEMS AND HOW TO CHECK YOUR CAR. BALANCE SHAFT MERCEDES V6 AND V8 PROBLEMS MERCEDES-BENZ V6 AND V8 ENGINES HAD TIMING CHAIN PROBLEMS CAUSED BY BALANCE SHAFT AND IDLER GEAR FAILURES. MERCEDES PRODUCED CERTAIN MODELS WITH DEFECTIVE GEARS IN THEIR BALANCE SHAFTS (M272 ENGINES) OR WITH DEFECTIVE IDLE GEARS ( M273 ENGINES). THESE FAULTY GEARS WEAR OUT PREMATURELY, EXCESSIVELY, AND WITHOUT WARNING, CAUSING THE VEHICLE TO MALFUNCTION, THE 'CHECK ENGINE LIGHT' TO REMAIN ILLUMINATED, AND THE VEHICLE TO MISFIRE OR STOP DRIVING.

THE TRANSMISSION HAS A FAULTY SHIFT SOLENOID THAT CAN ONLY BE REPLACED BY A MERCEDES BENZ DEALER AND THEREFORE IS MANY TIMES MORE EXPENSIVE THAN OTHER REPAIRS. ALSO THIS SOLENOID HAS A WELL ABOVE AVERAGE FAILURE RATE. MY CAR HAS 112,000 MILES AND THE TRANSMISSION BEGAN SHIFTING POORLY AND GOT STUCK IN 4TH GEAR. CAN BECAME VERY JERKY AND ONCE WENT INTO PARK WITHOUT ME SELECTING PARK, THIS HAPPENED AT A STOP LIGHT WITH CARS COMING UP BEHIND ME.

May 16, 2014
TRANSMISSION GOES INTO LIMP MODE AFTER SLOWING DOWN ON TO NEAR ZERO ON AN INTERSTATE HIGHWAY. THE RESULT IS THE CAR WILL NOT SHIFT DOWN INTO LOWER GEAR AND THUS WILL NOT ACCELERATE. CAR MUST BE TURNED OFF AND RE-STARTED ON INTERSTATE HIGHWAY IN TRAFFIC IN ORDER TO MAKE THE CAR OPERATE OR ABLE TO MOVE FORWARD. NEEDLESS TO SAY, STOPPING AND RE-STARTING A CAR ON THE INTERSTATE IS AN OBVIOUS SAFETY ISSUE... PARTICULARLY WHEN TRAPPED IN THE FAST LANE WITH NO WAY TO CROSS MULTIPLE LANES OF TRAFFIC TO GET TO THE SHOULDER (BECAUSE CAR WILL NOT ACCELERATE AND CANNOT MERGE INTO 70 MPH TRAFFIC TO CROSS). AS THIS IS A VERY COMMON PROBLEM THAT MERCEDES HAS ON SEVERAL PLATFORMS THAT SHARE THE 7-G TRONIC TRANSMISSION, I WOULD THINK THAT MERCEDES MUST ACKNOWLEDGE THE PROBLEM AS THERE IS NO WARNING THAT IT WILL HAPPEN AND WHEN IT DOES IT CAN EASILY PRESENT A VERY DANGEROUS SITUATION. A QUICK SEARCH OF 722.9 TRANSMISSION WILL SHOW HOW COMMON-PLACE THE ISSUE IS. *TR

MAY 13, 2019, MY WIFE STARTED THE CAR AND DROVE FOR LESS THAN A MILE WHEN HER DRESS STARTED SMOKING FROM THE DRIVER SEAT THAT WAS ALIGHT. SHE STOPPED THE CAR AND REMOVED OUR 11 MONTH OLD BABY FROM THE BACKSEAT AND CALLED ME. SHE HAS A VIDEO OF THE INCIDENT. I CHECKED ON MERCEDES USA SITE AND FOUND OUT THAT THERE WAS A CLASS ACTION LAW SUITE ON THIS ISSUE. WE WERE NOT NOTIFIED BY EITHER MB OR THE ADMINISTRATOR OF THE CASE. THIS COULD HAVE TURNED OUT DEADLY AS THE BATTERY IS UNDER THE PASSENGER SEAT AND THE FUEL LINES. I TURNED THE CAR ON AND AGAIN , THE SEAT STARTED TO SMOKE. IT IS NOW PARKED IN OUR DRIVEWAY AS MY WIFE AND I ARE SCARED OF PUTTING OUR KIDS IN IT. I CONTACTED MB USA AND THEY DIRECTED ME TO THE ADMINISTRATOR OF THE LAW SUITE. THIS CAN CREATE DANGEROUS OR EVEN DEADLY SITUATIONS IF MY WAS ON A HIGHWAY AND COULD NOT STOP OR FIE ESCALATES RAPIDLY WITH OUR CHILD IN THE BACK SEAT.

THE HEATED SEATS WERE TURNED ON THE DRIVER SEAT WHILE WAITING IN LINE AT A FAST FOOD DRIVE THRU ON JUNE 15, 2017 AROUND 1:00AM. I PULLED OF AFTER GETTING MY FOOD.

THE FIRE WENT OUT AND MY JACKET AND T SHIRT HAD BURNS AND ASHES ON THEM AND MY DRIVER SEAT HAD LARGE HOLE IN IT.

I STARTED MY 2006 MERCEDES-BENZ R350 AND ACTIVATED THE DRIVER SEAT WARMER ON HIGH. AFTER APPROXIMATELY 2.2 MILES INTO MY DRIVE (SPEED 30-45 MPH) MY SEAT FELT VERY HOT ON MY LOWER LEFT SIDE NEAR MY WAIST LINE. I REACHED BACK WHILE DRIVING TO FEEL HOW HOT THE SEAT WAS AND WAS SURPRISED BY A VERY HOT SENSATION AS THOUGH I HAD TOUCHED A HOT NEEDLE. AS I CONTINUED TO DRIVE AND PULL MY BODY FORWARD I NOTICED SMOKE RISING FROM BEHIND MY LEFT SHOULDER. I IMMEDIATELY PULL OVER ONTO A LEFT SIDE STREET AND PUT THE CAR IN PARK LEAVING IT RUNNING AND JUMPED OUT OF THE SEAT. THERE WAS A LARGE HOLE BURNED IN THE LEATHER AND IT WAS STILL SMOKING. I PATTED THE AREA DOWN WITH MY HAND TO NOTICE A GLOWING ORANGE SPARK AND IT CONTINUED TO SMOKE. I REACHED IN AND TURNED OFF THE HEATED SEAT BUTTON BY CYCLING IT THOUGH THE 2ND AND 3RD LEVELS. THE SEAT FINALLY STOPPED SMOKING. I LET THE HOLE IN THE SEAT COOL DOWN. CHECKING MY CLOTHING I REALIZED I HAD A HOLE AND SEVERAL MELTED SPOTS ON MY POLYESTER VEST I WAS WEARING. UPON COMING HOME I NOTICED ALSO A HOLE IN MY LIGHT COTTON SWEATER THAT WAS WORN UNDER THE VEST TWO DAYS PRIOR TO THIS INCIDENT I HAD FELT THE SEAT WAS HOT IN THE SAME AREA BUT THOUGHT MY SHIRT AT THE TIME WAS RAISED EXPOSING MY SKIN TO THE SEAT. *TR

VEHICLE HAS BEEN UNDRIVEABLE ON AND OFF FOR 6 MONTHS WITH DEFECTIVE STARTER WIRING HARNESS WHICH THE WIRES ARE EXPOSED, AND STARTING INTERMITTENTLY. TOWED FROM THE STREET 2 MONTHS AGO AND SITTING AT THE MECHANIC TRYING TO HELP ME. MERCEDES BENZ HAS A SAFETY RECALL #2006040002 FOR THE EXACT PROBLEM. THEY TELL ME IT IS FOR THE 2006 R350 AND NOT THE R500 MAYBE BECAUSE THEY WERE VERY LIMITED. THESES MODELS ARE THE SAME BUILT CHASSIS EVERYWHERE, INCLUDING THE STARTER WIRING HARNESS, EXCEPT I HAVE THE UPGRADED V8. AND THEY REFUSE TO FIX. SINCE THIS HAS CAUSED ME BREAK DOWN ISSUES AND IS A POTENTIAL SAFETY HAZARD AS DESCRIBED. I HAVE PAID $1200 A YEAR AGO TO REPLACE A DEFECTIVE WIRE HARNESS INSIDE THE CHASSIS, AS THE CAR SMOKED AND ALMOST CAUGHT FIRE AS I HAD TO PULL OFF THE ROAD AND TOW. AM I STUCK AGAIN??

AS PER RECALL#2006040002 IS THE EXACT PROBLEM I AM HAVING NOW. THE STARTER WIRING HARNESS IS DEFECTIVE AND EXPOSED, AND CAR IS DISABLED AT MERCEDES MECHANIC SITE. MBUSA SAYS IT IS ONLY TO CERTAIN R500S AND VIN SPECIFIC. I AM CONFUSED SINCE THIS IS LIMITED PRODUCTION.

WHILE I WAS DRIVING, I LOST POWER STEERING. I HAD TO PULL OVER AND SAW THAT MY ENGINE BELT WAS OFF MY ENGINE AND A PULLEY CAME OFF MY ENGINE. THIS IS AFTER THE DEALERSHIP HAD ALREADY REPLACED MY BELT JUST LESS THAN 10,000 BEFORE. IT WAS A GOOD THING THAT NO ONE WAS HURT. IT SEEMS LIKE THIS ENGINE IS DEFECTIVE AND MERCEDES BENZ REFUSES TO FIX THE PROBLEM. I'M AFRAID THAT SOMEONE WHO DOES NOT KNOW HOW TO HANDLE THE LOSS OF POWER STEERING WILL BE IN A FATAL ACCIDENT.

2006 MERCEDES BENZ R350 PROBLEM WITH FAULTY TRANSMISSION **CC THE VEHICLE ROLLED BACKWARDS OUT OF THE DRIVEWAY AND STRUCK A PARKED CAR. THE CONSUMER WAS TOLD BY THE DEALER, THE REASON WHY THE VEHICLE ROLLED, WAS BECAUSE HE LEFT THE KEYS IN THE IGNITION. THE CONSUMER STATED A BUTTON MUST BE PUSHED TO PLACE IN TO PARK.

THE VEHICLE'S REAR DRIVERS SIDE BRAKE OR REVERSE LIGHT WOULD NOT GO OFF FOR A WEEK (TO MY KNOWLEDGE) AND WHILE SITTING IN THE PASSENGER SIDE I TURNED ON THE HEAT WARMING DEVICE AND THERE WAS NO PROBLEM. IT WAS AFTER WE HAD BEEN SHOPPING AND RETURNED TO THE VEHICLE DID WE NOTICE A SMELL OF SOMETHING BURNING, BUT COULD NOT TELL WHERE IT WAS COMING FROM. STILL UNAWARE THAT A FIRE COULD START FROM THE BACK OF THE VEHICLE, IS WHEN WE REALIZED THAT THE CARGO AREA OF THE VEHICLES SIDE PANEL WAS IN COMPLETE FLAMES! THUS, CAUSING PHYSICAL AND MENTAL INJURIES, SMOKE AND PROPERTY DAMAGE AND A COMPLETE SENSE OF INSECURITY. THE VEHICLES MAIN SECURITY FEATURE NEVER WARNED US OF ANY POTENTIAL LIFE THREATENING DANGER AS IT WOULD IF MY TIRE WAS LOW AND THE ON CALL SYSTEM FAILED TO BE HELPFUL WHEN TRYING TO GET HELP, FOR WE WERE ONLY ABLE TO HEAR THE REPRESENTATIVES BUT NOT COMMUNICATE WITH THEM WHICH LED TO 5 REPRESENTATIVE DISCONNECT CALLS.
