2006 MERCEDES BENZ ML350 Power Train Problems

My car was included in the balance right shaft recall as 2nd owner I was just made aware as a result my check engine light came on. It was also learned that the car was included in faulty “balance shaft”. I should be included because my car has same diagnosis as defective equipment

i encountered a major issue with the Mercedes ML350, while doing a 3 point turn in a busy suburban Toronto street.The electronic shift module left me stuck in Road way. Causing traffic back up and could not move vehicle.neither forward or reverse.tried pushing and different tactics to move vehicle off road. Had to call CAA-AAA. It was a caos situation,first tow truck could not load vehicle,all wheels were locked in drive and would not shift. Had to wait for special tow Have all four wheels lifted off onto dolly. Tow truck driver said it is a common problem.with MB,BMW and Audi.Vehicles towed to dealer sat at dealer. parts on back order and Not available for repair.Since was in Toronto away from Home. Had to source original equipment supplier to purchase part.Dealer and factory Mercedes could Not source part.back ordered.The dealer agreed to install the factory OEM part they could not source. My concern to all owners including myself in line traffic a basic traffic maneuver stuck in blocking traffic. Cannot moving vehicle jammed in gear that controlled by a shift module.no safe limp mode or emergency shift to neutral to move vehicle safely.

Brakes feel spongy,, when letting off accelerate feels as if transmission has a brake applied

PULLING OUT INTO LANE OF TRAFFIC ACCELERATING WHERE CAR ABRUPTLY STARTS TO RUN VERY VERY ROUGH. CHECK ENGINE LIGHTS COME ON AND CAN BECOME UNSAFE WITH NO POWER AND ONCOMING TRAFFIC APPROACHING. SIMILARLY WHILE DRIVING OVER 60MPH SAME SCENARIO CAUSING CEL TO COME ON AND CAR TO DISENGAGE CRUISE AND SLOW EXTREMELY FAST. VERY ROUGH RUNNING AND IDLE. TERRIBLE FEELING OF BEING UNSAFE AND AT RISK. FINDING P0016 AND P0017 CODES AND ALL SYMPTOMS OF BALANCE SHAFT ISSUE THAT THE MB M272 IS KNOWN FOR. MY WIFE AND I ARE AFRAID TO DRIVE THIS VEHICLE NOW KNOWING IT HAD A KNOWN DEFECTIVE ENGINE COMPONENT IN A SOFTWARE BALANCE SHAFT GEAR

Mileage: 95,000

WHILE DRIVING AT MOST ANY SPEED,TRANSMISSION PERIODICALLY GOES INTO NO GEAR OR A SINGLE GEAR (LOW OR A HIGHER GEAR) AND 'LIMP MODE' WITHOUT WARNING....SOMETIMES A "CHECK ENGINE" LIGHT. VERY SCARY ESPECIALLY IN TRAFFIC ON THE FREEWAY. BOUGHT THE VEHICLE EARLIER THIS YEAR WITH 60,000 MILES ON IT...I AM 72 AND WIFE IS 71...SHE IS AFRAID TO DRIVE IT BECAUSE OF THE UNCERTAINTY OF THE DRIVE TRAIN. I FINALLY TOOK IT TO MERCEDES BENZ AS THE WOULD NOT SELL MY MY INDEPENDENT MECHANIC THE PARTS TO REPAIR PROBLEM. MERCEDES SAYS THAT I NEED TO HAVE THE 722.9 TRANSMISSION VALVE BODY REPLACED AT $3,000 PERIOD. I HAVE READ OF A MYRIAD OF SIMILAR PROBLEMS WITH OTHER OWNERS OF CARS WITH THIS TYPE OF TRANSMISSION....EVEN CLASS ACTION SUITS. I BELIEVE THAT THIS IS A VERY DANGEROUS CONDITION THAT MUST BE RESOLVED AND REPAIRED BY THE MANUFACTURER. I EVEN CALLED MERCEDES BENZ OF NORTH AMERICA AND THEIR REPRESENTATIVE SAID HE KNEW OF NO PROBLEMS WITH THIS MODEL OF TRANSMISSION. I ALSO READ THAT THEY ARE NOT CHANGING ANY PARTS....JUST REPROGRAMMING THE TRANSMISSION TO NOT GO INTO LIMP MODE AND NOT ACTIVATING THE CHECK ENGINE LIGHT.....HOW CAN I INSURE THAT MY VEHICLE WILL BE REPAIRED CORRECTLY AND BE SAFE TO DRIVE?

MY CAR SUDDENLY LOST POWER IN THE HIGHWAY, AND DIDN'T WANT TO ACCELERATE,CAUSING CAR TO HIGH RPM REV,GOING INTO LIMP MODE AND NOT ACCELERATE, ALMOST CAUSING MY FAMILY AND TO HAVE A SERIOUS ACCIDENT.VEHICLE WAS DIAGNOSED BY A SHOP WHICH STATED MY SPEED SENSOR CONDUCTOR PLATE IS DEFECTIVE...UPON DOING RESEARCH, I HAVE NOTICED THAT THIS IS COMMON DANGEROUS ISSUE ON THE 06 MERCEDES ML MODELS..MERCEDES EVEN HAS A CLASS ACTION SUITE AGAINST THEM DUE TO THIS ISSUE..

THERE IS A SYSTEMIC PROBLEM WITH THE MERCEDES BENZ 7G TRONIC 722.9 TRANSMISSION CONTROL MODULE WHICH CAUSES THE VEHICLE'S TRANSMISSION TO, WITHOUT NOTICE, FAIL TO SHIFT OUT OF 2ND GEAR WHICH CREATES A SERIOUS SAFETY HAZARD WHILE DRIVING INCLUDING ENTERING THE FREEWAY AND ATTEMPTING TO MERGE INTO TRAFFIC. THE ISSUE IS WELL DOCUMENTED ON A NUMBER OF WEBSITE ON THE INTERNET WHICH INCLUDES SUPPORT GROUPS INCLUDING ONE ADVOCATING AND SOLICITING A CLASS ACTION SUIT IN THE STATE OF CA. THE NHTSA NEEDS TO LOOK INTO THIS MANUFACTURER'S DEFECT SO AS TO PREVENT SERIOUS INJURY INCLUDING THE LOSS OF LIFE. MB USA IS VERY MUCH AWARE OF THE ISSUE WHICH REQUIRES THE REPLACEMENT OF TRANSMISSION CONTROL MODULE (TCM). ADDING INSULT TO INJURY, MB RESTRICTS THE SALE OF THE TCM SO THAT THE REPAIR CAN ONLY BE MADE AT AN AUTHORIZED MB DEALERSHIP ADDING TO THE CONSUMER'S COST TO REPAIR THE VEHICLE. THE ESTIMATE REPAIR COST IS $1,500 AT THE DEALERSHIP. COST ESTIMATES OUTSIDE OF THE DEALERSHIP, IF THE ITEM WAS ABLE TO BE PURCHASED, IS LESS THAN HALF THAT. I WAS NEARLY REAR ENDED BY A TRACTOR TRAILER WHILE ENTERING I-91 IN CT JUST LAST WEEK WHEN THE VEHICLE UNEXPECTEDLY WENT INTO WHAT MB CALLS "LIMP MODE" WHEN THE CHECK ENGINE LIGHT COMES ON AND THE VEHICLE SPEED IS RESTRICTED TO 30 MPH IMMEDIATELY. THIS NEAR DEATH EXPERIENCE WAS QUITE ALARMING. I CONTACTED MB USA AND THEY DENIED ANY KNOWLEDGE THAT THE PROBLEM WAS AT ALL DUE TO DEFECTIVE MANUFACTURING. AS AN INDIVIDUAL CONSUMER WE HAVE NO RIGHTS IN THIS MATTER TO ELIMINATE THIS MANUFACTURERS SAFETY DEFECT WHILE MB RESTRICTS AND MONOPOLIZES THE REPAIR OF A PROBLEM THAT THEY CREATED. THE FAILURE OF THIS PART CAN HAPPEN AT ANY TIME REGARDLESS OF VEHICLE MILES. *TR

MY 2006 MERC ML350, BROKE DOWN ON ME 10/22/16, AS SOON AS I GOT OFF THE FREEWAY BECAUSE I WAS HEARING A CRACKLING SOUND FROM THE ENGINE. I WAS ABLE TO DRIVE IN A LOCAL PARKING LOT TO AVOID EMBARRASSMENT. THIS VEHICLE IS ALWAYS NEEDING SOMETHING, AND AT THIS TIME IT WAS HARD TO TURN THE STEERING WHEEL TO PARK IT BECAUSE THE SERPENTINE (VBELT) HAD UNRAVELED ITS WAY FROM THE ALTERNATOR PULLEY!! THE LORD HAD SAVED MY LIFE! SAME YEAR IN MARCH FREMONT DEALERSHIP SAID I NEEDED TO REPLACE MY AIR CONDENSOR BUT NEVER SAID ANYTHING ABOUT MY BELT BEING WORN OR CRACKED OR ANYTHING ABOUT THIS. THIS SHOULD HAVE BEEN NOTICED AT THAT PRESENT TIME. THEY MISINFORMED ME AT THAT TIME ABOUT THE VBELT NEEDING TO BE REPLACED AND TRIED TO SELL ME A AIR MASS SENSOR. MERCEDES KNOWS ABOUT VEHICLE 2006 YEAR AND ALL THE PARTS THAT ARE MALFUNCTIONING AND WONT LIFT A FINGER TO RECALL OR REIMBURSE OR PAY ENTIRELY. I WOULD HAVE DIED ON THE FREEWAY HAD THIS V BELT WOULD HAVE CAME OFF! TOOKBITVIN FOR REPAIRS AND THE DEALER IS REQUESTING $2350 TO REPLACE AIR CONDITION UNIT AND THEY WILL HAVE TO OPEN UP ALTERNATOR & ADJUST + VBELT. CAMPAIGN ANYONE OR BOTCOTT MBUSA!! *TR

CHECK ENGINE LIGHT CAME ON, AND GOT BOTH CODES P0016 AND P0017. UPON FURTHER INVESTIGATION, THIS SEEMS TO BE A KNOWN DEFECT BY MERCEDES BENZ FOR THE BALANCER SHAFT WORN SPROCKET ISSUE. THIS IS AN EXPENSIVE REPAIR, ALMOST THE COST OF THE VEHICLE! MBUSA PICKS AND CHOOSES WHO THEY WILL HELP? WOW, WISH I NEVER GOT THIS CAR!

MY 2006 ML350 (AUTOMATIC) HAS A TRANSMISSION PROBLEM WHERE SHIFTING DOWN CAUSES THE VEHICLE TO LUNGE FORWARD. ALL GEAR SHIFTS (UP OR DOWN) ARE HARD AND CAN BE FELT BY THE OCCUPANTS IN THE CAR IN THE FORM OF A JERKY MOTION. SCOURING THE INTERNET FOR THIS ISSUE SHOWS THAT THIS IS A WIDELY REPORTED PROBLEM. THE VEHICLE WAS TAKEN TO THE DEALER FOR DIAGNOSIS WHO OFFERED TO REPLACE THE TRANSMISSION FOR $7500. WHEN ASKED ABOUT THE ROOT CAUSE OF THE ISSUE, THE DEALER STATED THAT THEY WOULD NOT KNOW UNTIL THEY TAKE THE TRANSMISSION APART AND WOULD END UP COSTING ROUGHLY THE SAME AS REPLACING THE TRANSMISSION. THE DOWN SHIFTING PRESENTS A DANGER WHEN MAKING SUDDEN STOPS DUE TO UNFORESEEN TRAFFIC CHANGES IN FRONT OF THE VEHICLE AS BRAKING HARD CAUSES THE VEHICLE TO DOWN SHIFT QUICKLY WHICH CAUSES THE VEHICLE TO LUNGE FORWARD.

THE VEHICLE IS GETTING STUCK IN 7 GEAR ON THE FREEWAY AND NOT DOWN-SHIFTING TO ALLOW PASSING. EVEN WHEN COMING TO A STOP, THE CAR WILL REMAIN IN 7TH GEAR. THIS IS A DANGEROUS CONDITION BECAUSE THE CONSUMER DOES NOT KNOW THE CAR IS NOT SHIFTING CORRECTLY. MERCEDES IS AWARE OF VALVEBODY AND CONDUCTOR PLATE ISSUES WITH THESE CARS. *TR

THIS VEHICLE HAS HAD NOTHING BUT PROBLEMS. AT AROUND 32,000 IT NEEDED TRANSMISSION REPAIR. UNFORTUNATELY IT WAS PAST THE THREE YEAR OFFERED WARRANTY. AT AROUND 45,000 MILES, I WAS TOLD THAT IT NEEDED NEW SHOCKS. ALL OF THE REPAIR MEN THAT I SPOKE WITH COULD NOT BELIEVE THAT THIS VEHICLE WOULD NEED SUSPENSION WORK AT SUCH LOW MILEAGE. AFTER READING THESE POSTS, IT IS CLEARLY A DEFECT IN THE SUSPENSION. MEANWHILE, I WENT THROUGH ANOTHER SET OF TIRES BECAUSE I AM STILL WAITING TO REPAIR THE SUSPENSION. I GUESS I CAN WAIT NO LONGER AND WILL NEED TO COME OUT OF POCKET AGAIN. THIS VEHICLE HAS BEEN A NIGHTMARE AND BASED ON THIS EXPERIENCE, I WILL NEVER BUY ANOTHER MERCEDES. *TR

DEFECTIVE IDLE GEARS/THESE DEFECTIVE 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 AND /OR STORE DRIVING. MERCEDES ACTUAL KNOWLEDGE AND INTENTIONAL CONCEALMENT OF THE DEFECT DUE TO COMPANY REPUTATION DON'T WANT THE PUBLIC TO KNOW AND MAY HURT THE COMPANY IMAGE. I WAS SHOCK AFTER WHAT I WAS EXPLAINED BY MERCEDES ADVISORY NOT TAKING ANY RESPONSIBLE FOR DEFECTED GEARS AND WANTED TO CHARGE ME. VERY BAD EXPERIENCE WITH MERCEDES. *TR

I BOUGHT A 2006 MERCEDES 3 YEARS AGO THINKING I WOULD HAVE A CAR FOR A LIFETIME BOY DID I GO WRONG. IN THE PAST 3 MONTHS I HAVE HAD MAJOR PROBLEMS AND MERCEDES DOESN'T CARE. THE FIRST ISSUE I HAD TO REPLACE THE CRANK SHAFT $6000 PLUS FOR REPAIR I ALMOST WENT CRAZY SO I STARTED RESEARCHING ON THE INTERNET AND FOUND OUT THERE WAS A CLASS ACTION LAW SUIT FOR THIS ISSUE SO I PHONED MERCEDES AND THEY AGREE TO PICK UP HALF OF THE REPAIR. ONE MONTH LATER CAR STARTS MAKING WINDING NOISE TAKE IT BACK TO THEM AND NOW THEY SAY IT IS THE FRONT DIFFERENTIAL $5500 TO REPAIR I START TO RESEARCH THAT ON THE INTERNET AND THERE ARE SO MANY COMPLAINTS FOR MY SAME ISSUE ON THE SAME YEAR AND MODEL SO I GO BACK TO MERCEDES HOWEVER THIS TIME NOT WILLING TO HELP. HOW MANY COMPLAINTS IS IT GOING TO TAKE FOR SOMETHING TO BE DONE TO SUCH A POWERFUL COMPANY LIKE MERCEDES. I TRULY DO NOT THINK THIS IS FAIR AND US THE CONSUMERS ARE BEING RIPPED OFF. *JS

CAR DOES NOT DOWN SHIFT WHEN SLOWING DOWN TO STOP. THEN WHEN YOU TRY TO ACCELERATE IT BARELY MOVES. ONE HAS TO PLACE THE TRANSMISSION INTO PARK, THEN TURN ENGINE OFF AND THEN RESTART ENGINE TO RESET TRANSMISSION. FAULT CODES IN THE ONBOARD COMPUTER ALL POINT TO VALVE BODY CONDUCTOR PLATE ON TRANSMISSION. MERCEDES WILL NOT SELL OR REPLACE PART TO INDEPENDENT MECHANICS. THEY WILL ONLY SELL IT TO DEALERS WHICH I BELIEVE ARE TOLD TO DIAGNOSE A DIFFERENT PROBLEM. IN OTHER WORDS WORK AROUND THE PROBLEM TO GENERATE INCOME BEFORE ACTUALLY TRYING TO FIX THE ACTUAL PROBLEM. THIS IS A WELL DOCUMENTED PROBLEM AMONGST ML 350 OWNERS WITH SOME PAYING THOUSANDS AND STILL NOT HAVING THE PROBLEM CORRECTED. PLEASE LOOK INTO THIS BECAUSE THIS CAN BECOME A SAFETY ISSUE ESPECIALLY AT A BUSY TRAFFIC LIGHT.

AT APPROXIMATELY 70K MILES, I BEGAN TO NOTICE A LOW-FREQUENCY WHINING NOISE IN THE FRONT END OF MY ML-350 AT SPEEDS ABOVE 40 MPH. THE NOISE BECAME MORE PREVALENT WHEN I TOOK MY FOOT OFF OF THE ACCELERATOR AT HIGHER SPEEDS. FIRST, REPLACED ALL FOUR TIRES WITH MICHELIN "LATITUDE TOUR HP" - $1,300 (INCLUDING ALIGNMENT). THE NOISE STILL OCCURRED. NEXT, TOOK TO MB SPECIALIST, WHO RECOMMENDED BOTH WHEEL BEARING BE REPLACED - COST $425/SIDE. THE BEARINGS WERE REPLACED AND NOISE STILL OCCURRED. MB SPECIALIST RECOMMENDED CHECKING DIFFERENTIAL OIL FOR METAL - FOUND LOTS OF METAL FRAGMENTS IN DIFFERENTIAL OIL. INSTALLATION OF NEW DIFFERENTIAL WAS ~$3,500. MB SPECIALIST STATED THAT HIS PARTS DISTRIBUTOR SAID THAT THEY SELL AT LEAST ONE-TO-TWO LATE MODEL ML-350 FRONT END DIFFERENTIALS PER MONTH. IN MY OPINION, IT SEEMS AS THOUGH THERE IS A FLAW IN THE DIFFERENTIAL'S DESIGN OR MANUFACTURING PROCESS, AS I SEEN SEVERAL REPORTS OF THE SAME DIFFERENTIAL ISSUES WITH [RELATIVELY]-LOW-MILEAGE/LATE-MODEL MB ML-350 SUVS. I WOULD LIKE TO SEE MB RESEARCH THIS ISSUE, AND POSSIBLY INSTATE A RECALL OR REIMBURSE MB OWNERS WHO'VE ALREADY AFFECTED COSTLY REPAIRS ON THEIR LOW-MILEAGE ML-350'S FRONT END DIFFERENTIALS. *TR

TOOK CAR TO MB DEALERSHIP IN NORTH OLMSTED OHIO BECAUSE FRONT END OF CAR AND STEERING WHEEL STARTED SHAKING AND VIBRATING EXCESSIVELY WHEN THE CAR WAS DRIVEN IN EXCESS OF 60 MPH. CAR DROVE FINE UNDER THAT SPEED. I ALMOST WAS CAUSED TO DRIVE OFF OF ROAD AT MULTIPLE POINTS BECAUSE OF EXCESSIVE VIBRATION AND LACK OF STEERING CONTROL. CONDITION DID NOT OCCUR AT LOWER SPEEDS. CAR WAS 1 WEEK OUTSIDE OF MFR WARRANTY. WAS TOLD BY MB DEALERSHIP THAT CAR NEEDED NEW FRONT DIFFERENTIAL. I CALLED MB NATIONAL TO COMPLAIN ABOUT AN ALLEGED LUXURY CAR'S FRONT DIFFERENTIAL FAILING ONLY AFTER 40K MILES. THEY TOLD ME IT WAS NOT THEIR PROBLEM. CAR CONTINUES TO HAVE PROBLEM TO THIS DAY (1 YEAR LATER). I WAS TOLD THAT THE CAR WAS SAFE TO DRIVE. I HAVE SINCE BEEN LOOKING FOR A USED DIFFERNTIAL BECAUSE A NEW ONE W/INSTALL IS OVER $3K. IT SEEMS AS IF I AM NOT THE ONLY ML OWNER EXPERIENCING THESE PROBLEMS. MB WENT WITH A NEW 7 SPEED TRANSMISSION THAT YEAR WHICH MAY LEAD TO PROBLEMS. *TR

AROUND 45,000 MILES THE CHECK ENGINE LIGHT CAME ON. I TOOK THE VEHICLE TO A MERCEDES BENZ DEALER SERVICE DEPARTMENT AND WAS NOTIFIED THAT THE BALANCE SHAFT NEEDS TO BE REPLACED. IN ORDER TO REPLACE THE BALANCE SHAFT, THE ENGINE NEEDS TO BE TAKEN OUT OF THE VEHICLE AND TAKEN APART. ESTIMATED COST $6,000. THE SERVICE DEPT. TOLD ME THAT IT WAS DUE TO A PART THAT WAS NOT HARDENED PROPERLY DURING MANUFACTURING. THERE IS A TECHNICAL SERVICE BULLETIN (S-B-03.30/08I) THAT WAS ORIGINALLY ISSUED IN 2007 WHICH WAS FOUND IN INTERNET SEARCHING, HOWEVER IT SEEMS LIKE MERCEDES BENZ KNOWS THAT THE CHECK ENGINE LIGHT (ON THE MAJORITY OF THESE VEHICLES) WILL NOT COME ON UNTIL WHEN THE WARRANTY HAS EXPIRED. SINCE THIS FIX IS A HUGE EXPENSE, THEY ARE NOT GOING TO ISSUE A RECALL EVEN THOUGH IT IS CLEARLY A SAFETY CONCERN. IF I WOULD'VE HAVE CONTINUED TO DRIVE THE VEHICLE IN THIS CONDITION, EVENTUALLY THE BALANCE SHAFT WOULD HAVE CONTINUED TO BREAK ITS TEETH RESULTING IN ENGINE FAILURE. CONTINUING TO DRIVE THE VEHICLE IN THE CONDITION IS NOT SAFE, IT IS A MATTER OF TIME BEFORE THE VEHICLE STOPS RUNNING AND THE ENGINE WOULD NEED TO BE REPLACED. THE MERCEDES BENZ USA REPLACED OUR BALANCE SHAFT OR PAY FOR IT PEOPLE WHO ALREADY FIXED. *TR

HELLO I LIVE IN NY AND I HAVE A 2006 ML350. RECENTLY I BROUGHT MY CAR IN FOR A CHECK ENGINE LIGHT TO MERCEDES BENZ. THEY STATE THE CAR NEEDS NEW BALANCE SHAFT AND TIMING GEARS. THE CAR ONLY HAS 46,000 MILES. THIS SHOULD NOT BE POSSIBLE. THE COST IS OVER $5,000 TO GET FIXED. MERCEDES WILL NOT COVER IT. THIS SEEMS TO BE A DEFECT PART. IN RESEARCHING THE PROBLEM I FOUND OUT I WASN'T THE ONLY WITH THIS ISSUE. THERE IS A CLASS ACTION LAWSUIT IN NEW JERSEY AS WELL AS OTHER STATES. MY INSPECTION HAS EXPIRED AND CAN'T NOT PASS WITHOUT THE REPAIR WHICH IS A SAFETY ISSUE. HERE IS THE LINK TO THE CLASS ACTION LAWSUIT HTTP://WWW.COURTHOUSENEWS.COM/2010/10/07/MERCEDES.PDF.

TOLD ME THAT IT WAS DUE TO A PART THAT WAS NOT HARDENED PROPERLY DURING MANUFACTURING. THERE IS A TECHNICAL SERVICE BULLETIN (S-B-03.30/08I) THAT WAS ORIGINALLY ISSUED IN 2007, HOWEVER IT SEEMS LIKE MERCEDES BENZ KNOWS THAT THE CHECK ENGINE LIGHT (ON THE MAJORITY OF THESE VEHICLES) WILL NOT COME ON UNTIL AFTER 50,000 MILES, WHEN THE WARRANTY HAS EXPIRED.

HERE IS A BRIEF BREAKDOWN: 28.8 LABOR HOURS TOTAL $2,940.48, PARTS $1,263.50 (CONSUMER COST), $925.49 (NET COST). THE FAILURE HAS BEEN CORRECTED, HOWEVER THE SERVICE DEPT. TOLD ME ALL OF THESE VEHICLES MADE DURING THIS TIME WILL EVENTUALLY HAVE THIS FAILURE AND IT'S A SAFETY CONCERN, NOT TO MENTION A VERY EXPENSIVE REPAIR. I FEEL THERE SHOULD BE A RECALL ISSUED FOR THESE VEHICLES AND MERCEDES BENZ SHOULD BE REQUIRED TO NOTIFY CONSUMERS OF THIS FAILURE. I WAS AN ORIGINAL PURCHASER AND HAD MINE REPAIRED, HOWEVER THERE ARE PEOPLE OUT THERE BUYING THESE VEHICLES USED UNAWARE OF THE PROBLEM, NOT ONLY STUCK WITH A $4,000 + REPAIR, BUT ALSO UNAWARE OF THE SAFETY HAZARD.

BENZ ML 350 - I WAS SITTING AT A TRAFFIC LIGHT AND WHEN I ATTEMPTED TO PULL OFF, THE VEHICLE STARTED DRIVING VERY SLOW AND ROUGH.
