LOSS OF POWER STEERING FLUID, IT APPEARS TO BE FROM THE HOSE CONNECTION TO THE RADIATOR DURING DRIVING AND WHILE STATIONERY. THIS ISSUE WAS PREVIOUSLY RECALLED, I BELIEVE TWICE. DEALER REQUESTED $125 DIAGNOSTIC CHARGE. MB USA INFORMED IN A PHONE CONVERSATION, THAT THIS PROBLEM WAS ALREADY FIXED OCTOBER 2008 UNDER RECALL, AND THE WARRANTY EXPIRED AND I SHOULD FIX ON MY OWN COST.

I RECENTLY HAD TO REPLACE THE POWER STEERING PUMP, RESEVIOUR, AND HOSE AFTER LOOSING CONTROL WHILE DRIVING ON THE HIGHWAY. IMMEDIATELY AFTER REFILLING WITH FLUID ALL THE CONTENTS RAN RIGHT OUT. I DO SEE THAT THERE WAS A RECALL FOR THIS PROBLEM IN 2008, BUT I DID NOT TAKE OWNERSHIP OF THIS VEHICLE UNTIL 2/15. IS THERE ANY WAY POSSIBLE FOR THIS PROBLEM TO BE FIXED UNDER THE RECALL?

Oct 17, 2011
I OWN A MERCEDES ML 350 2003; WHILE DRIVING THE CAR TO WORK THIS MORNING THE CAR STOPPED ACCELERATING, BECAME DISABLED AND STEERING, BECAME IMPOSSIBLE. THE CAR SLOWED ON ITS OWN WHILE I WAS IN TRAFFIC ON A MAJOR ROAD WITH SPEED LIMITS UP TO 40 MPH AND I WAS UNABLE TO MOVE THE CAR INTO THE SHOULDER CREATING A MAJOR SAFETY ISSUE. EVENTUALLY THE CAR COASTED ONTO THE SHOULDER AND ALL LIGHTS BECAME ILLUMINATED ON THE DASHBOARD. UPON HAVING IT TOWED TO MERCEDES BENZ I WAS TOLD THAT IT WAS INITIALLY A KEY FAILURE IN WHICH COMMUNICATION BETWEEN THE KEY AND THE COMPUTER IN THE CAR COULD BE LOST WHICH WOULD RESULT IN A LOSS OF POWER TO THE VEHICLE. AFTER MY REACTION WHICH WAS "AND YOU GUYS ARE COMFORTABLE WITH THAT" I WAS TOLD THAT INSTEAD IT WAS THE CRANK SHAFT SENSOR. CURRENTLY MERCEDES HAS A RECALL PENDING OR BEING CONSIDERED ON ONE OF THERE 2007 MODELS FOR THE SAME PROBLEM, BUT THIS WAS NOT COVERED UNDER WARRANTY AND IS NOT CURRENTLY A RECALL, BUT SHOULD BE. THERE ARE NUMEROUS COMPLAINTS ON THE WEB REGARDING THIS ISSUE. *TR

May 20, 2005
I WAS PULLING INTO A PARKING SPACE (WITH MY 3 SMALL CHILDREN STRAPPED IN THE BACK), WHEN I REALIZED THAT THE CAR WAS NOT STOPPING. I PRESSED THE BRAKE HARDER, THE CAR ACCELERATED, JUMPED THE CEMENT MEDIAN, AND HIT A PARKED CAR. THANK GOD NO ONE WAS INJURED. I AM SICK THINKING WHAT COULD OF HAPPENED. THE CAR IS 6 MONTHS OLD AND HAS BEEN BACK TO THE DEALERSHIP TWICE FOR A PROBLEM I BELIEVE WAS THE BEGINNING OF THIS, I.E., WHEN I WOULD STEP ON THE BRAKE IT WOULD GO TO STALL, BUCK FORWARD AND THEN BE OK. THE DEALERSHIP WAS UNABLE TO FIND IT OR DUPLICATE IT. I HAVE SEEN WHERE OTHER PEOPLE ARE HAVING THIS SAME PROBLEM. ALSO FOR 2003 THE MODEL IS ML 350 - MERCEDES. AGAIN THEY HAVE NOT FOUND A PROBLEM. THEY SENT THE MANUFACTURER OUT TO CHECK THE CAR AND NOTHING. I HAVE A POLICE REPORT THAT STATES THE RESPONDING POLICE OFFICER AND TOW TRUCK DRIVER CONCUR THAT THE BRAKES WERE DOWN TO THE FLOOR BOARD AND NOT ENGAGING.*JB

MY M-350 HAD NO POWER. THE HARNESS CABLE (163-540-28-32) LOCATED BEHIND AND AGAINST THE BATTERY HAD COMPLETELY BEEN DESTROYED BY THE BATTERY ACID ENVIRONMENT. THE CABLE SUPPLIES THE OPERATIONAL POWER TO THE ELECTRICAL FUNCTIONS OF THE AUTO. IF I HAD BEEN DRIVING WHEN THIS COMPLETE FAILURE OCCURRED I COULD HAVE BEEN KILLED OR COULD HAVE KILLED SOMEONE ELSE. ALL SYSTEMS IN THE CAR WERE TOTALLY NON-FUNCTIONAL. NO SHIELDING OR PREVENTION OF DAMAGE TO THE CABLE WAS ENGINEERED INTO THE FACTORY INSTALLATION OF THIS CABLE. THE BATTERY WAS THE ORIGINAL INSTALLATION AND NO MAINTENANCE ACTIVITY HAD OCCURRED IN THAT AREA OF THE CAR SINCE IT WAS MANUFACTURED. I HAVE SEVERAL PHOTO OF THE CABLE THAT SHOWS THIS CONDITION. I WAS CHARGED $2,483.65 BY JACKIE COOPER IMPORTS OF TULSA, LLC ( THE TULSA MERCEDES-BENZ DEALER) TO REPLACE THE CABLE. I ALSO WAS CHARGED APPROXIMATELY $125.00 FOR THE TOWING OF THE CAR (SUV) TO THE DEALER FOR THESE REPAIRS. FOR A WORLD CLASS SAFETY AWARD WINNER CAR, TO BE ENGINEERED WITH THE ELECTRICAL HARNESS CABLE NEXT TO A BATTERY WITHOUT PROTECTION FROM ACID FUMES IS TOTALLY UNPROFESSIONAL. I'M WORK IN THE AEROSPACE INDUSTRY AND WE WOULD NEVER ALLOW THIS INSTALLATION TO BE APPROVED. PLEASE RESPOND TO THIS REQUEST SO I CAN FORWARD THE PHOTOS AND COPIES OF THE REPAIR ORDERS. I WOULD RECOMMEND THAT A RECALL NOTICE BE IMPLEMENTED ON THIS VEHICLE TO AVOID POTENTIAL DEATHS, INJURIES, AND LOSS OF PROPERTY TO THE PUBLIC. *TR

ON THE HIGHWAY DRIVING 65 MY 2003 ML500 MERCEDES - BENZ COMPUTER SHUT DOWN AFTER HITTING A SMALL BUMP. IT WAS VERY DANGEROUS AND WAS SCARED FOR MY LIFE THERE ENGINE TURNED OFF AND WAS LUCKILY ABLE TO STOP AT THE SIDE OF THE ROAD AND START THE CAR AGAIN. THIS HAPPENED A COUPLE OF WEEKS BEFORE BUT IT STOPED FOR JUST A SECOND OR TWO. THIS ISN;T AN LD CAR WITH ABOUT 25K MILES ON IT. FOR A 55 THOUSAND DOLLARS CAR TO DO THAT IS UNACCEPTABLE.*AK

I PURCHASED A NEW 2003 ML 350 DURING THE MEMORIAL DAY SALE FROM OUR LOCAL MERCEDES DEALER IN IOWA CITY, IA. THE SUV SHUTS OFF AUTOMATICALLY. INITIALLY, THE DEALER REPLACED THE BATTERY. THE SUV HAS BEEN INTO THE DEALER THREE ADDITIONAL TIMES FOR THE SAME PROBLEM. EACH TIME, THE DAY AFTER I RECEIVED THE ML350 BACK, THE PROBLEM OCCURS AGAIN. TWO INCIDENTS OCCURRED WHERE THE SUV WOULD NOT START IN MY GARAGE (WHICH PRESENTED NO HAZARD). TWO INCIDENTS OCCURRED WHERE I WAS DRIVING THE VEHICLE. THIS IS AN EXTREME SAFETY HAZARD - PARTICULARLY IF YOU TRAVELING AT A HIGH RATE OF SPEED. THE DATE LISTED BELOW IS THE MOST RECENT INCIDENT. *LA

The Floor Mats I received for my vehicle covered a portion of my accelerator pedal and would when up into the back above the pedal and to the right of it and would get caught and force my accelerator pedal to stay down. I told the company of their design flaw, and they said would not do anything about it. If I wanted to send it back it would cost more than the pads were worth. I paid $189.95. I got PayPal involved and if I paid the shipping cost to send them back they would rebate me the money that I paid. That's only if the mats are in perfect condition when they receive them. So it cost hours of BS and $60 so I get back at least $129. But with that said I felt you should know that they are selling and sending things not made for the cars they promise they will be for.

ENGINE KEEPS GETTING OVER-HEATED EVEN AFTER A NEW ENGINE FAN HAS BEEN REPLACED. HOWEVER, AFTER ITS REPLACEMENT I TOOK IT TO TWO MERCEDES DEALERSHIP TO RE-INSPECT AND MAKE ADJUSTMENT TO THEIR INSTALLMENT OF THE FAN BUT IT KEEPS GETTING OVERHEATED.

RANDOM LOSS OF POWER ' (THE ENTIRE PANEL LIGHTS UP) AS THE CAR SUDDENLY AND SLOWLY POWERS OFF WHILE TAKING OFF FROM A DROP, DRIVING, BREAKING, AND TURNING, COMING TO A STOP AND ON THE HIGHWAY. IN THE PAST 6 MONTHS WE HAVE SPENT MORE THAN 3800.00 FOR CAR REPAIR ON THE ML 350. IT SHUTS OFF MORE AND MORE FREQUENTLY. SO MUCH SO WE DO NOT ALLOW OUR DAUGHTER TO DRIVE UNLESS I AM THERE AND NOW NOT EVEN THEN UNTIL WE HAVE HAD IT FIXED FOR THE 4TH TIME (WE THOUGHT) AFTER CRANK SHAFT, SPARK PLUGS AND NOW ELECTRICAL WORK WE ARE AT A TOTAL LOSS. THIS ISSUE IS NOT ISOLATED BUT MERCEDES BENZ HAS HAD OTHER REPORTS OUR AND OTHERS ' NOT REPAIR / OR RECALLED BUT IT SEEMS MAJOR TO OUR FAMILY ' AS MY ONLY VEHICLE AND OTHER OWNER THAT HAVE INVESTED IN THIS MAKE.

LOSS OF POWER STEERING DRIVING ON THE FREEWAY DUE TO SUDDEN BREAK OF IDLER ARM PULLEY AND SUBSEQUENT SHREDDING OF BELT. PROBLEM IS THE PULLEY IS MADE OF PLASTIC AND CRACKED IN TWO, LEAVING 1/2 THE PULLEY AND SHREDDING THE BELT. THIS OCCURRED AT DRIVING SPEED OF 50 MPH AND MILEAGE AROUND 169,650 ON 2003 ML500. THIS WAS VERY DANGEROUS. I WAS ABLE TO PULL OFF THE FREEWAY AS I WAS DRIVING IN THE LANE NEAREST FREEWAY EXITS. ALMOST IMPOSSIBLE BUT ABLE TO STEER INTO A PARKING LOT. LUCKY IT WAS 'RUSH' HOUR AND TRAFFIC WAS SLOW ON SURFACE STREETS. INCREDIBLE SAFETY ISSUE DUE TO DIFFICULTY TO STEER WITHOUT POWER STEERING. CAR IS REGULARLY MAINTAINED BY GERMAN MECHANIC FAMILIAR WITH REPAIR OF MB ENGINES IN GERMANY.

MY WIFE DROVE THE VEHICLE TO WORK ONE DAY AND WHEN SHE WAS PULLING OUT OF THE PARKING LOT ONTO A BUSY STREET, THE YELLOW TRIANGLE WITH EXCLAMATION POINT STARTED TO FLASH AND ENGAGED THE BRAKES. MY WIFE QUICKLY PULL OVER TO THE SIDE OF THE STREET AND MADE HER WAY BACK INTO THE PARKING LOT WHILE THE BRAKES WHERE ENGAGING. MY WIFE WAS UNABLE TO DRIVE THE VEHICLE HOME FROM WORK. WE LET THE VEHICLE SIT FOR SEVERAL MINUTES AND I WAS ABLE TO GET THE VEHICLE MOVING BUT THE BRAKES WERE ENGAGING AGAIN. I WAS ABLE TO GET THE VEHICLE BACK HOME. I HAVE TAKING THE VEHICLE TO SEVERAL SHOPS AND ALL THE SHOPS ARE SAYING THAT THERE IS AN ISSUE WITH THE TRACTION CONTROL SYSTEM. WHEN DRIVING THE VEHICLE FROM ONE OF THE SHOPS, AS SOON AS I PULLED OUT OF THE SHOP'S PARKING LOT THE BRAKES ENGAGED AND THE YELLOW TRIANGLE WITH EXCLAMATION WAS FLASHING. IT DID THIS FOR ABOUT 15 SECONDS CAUSED THE APPROACHING VEHICLE FROM THE REAR TO SLAM ON THEIR BRAKES TO AVOID REAR ENDING ME. THE VEHICLE HAS BECOME UNSAFE TO DRIVE BECAUSE WE JUST DON'T KNOW IF WHEN IT DOES THIS. IT HAPPENS RANDOMLY USUALLY AFTER THE VEHICLE AS BEEN SITTING OFF FOR A SEVERAL HOURS.

MY FAMILY OWNS A 2003 MERCEDES BENZ ML 350. A FEW WEEKS AGO, MY MOM NOTICED A BURN MARK ON THE DRIVER'S SEAT. WE BELIEVED ONE OF THE MECHANICS BURNT IT WITH A TOOL DURING THE CAR'S SERVICE. SO THIS BURN MARK WAS IGNORED. ON DEC. 13, 2008 AROUND 8:20 AM, MY MOM, WHO WAS DRIVING THE CAR, SMELLED SMOKE AND SAW SMOKE AND A SMALL FIRE FROM THE SIDE OF HER SEAT. SHE COULD NOT HAVE PULLED OVER QUICKLY BECAUSE OF TRAFFIC. SHE TURNED OFF THE SEAT WARMER. THEN SHE PUT IT OUT WITH A TOWEL SHE WAS SITTING ON, IT TOO WAS BURNT, BUT PREVENTED MY MOMS LEG FROM GETTING BURNED BY THE FIRE. THE FIRE HAS LEFT A BURNED HOLE IN THE DRIVER'S SEAT. I'VE CALLED CUSTOMER SERVICE, WHICH THEY HAVE NEVER HEARD OF A CASE LIKE MINE, NOR THE DEALERSHIP THAT I HAVE VISITED. THE CUSTOMER SERVICE AGENT DOCUMENTED MY CASE AND FAXED A COPY TO THAT DEALERSHIP.
