Engine has low power and a whine. Also has a Check Engine Light indicating Center Balance Shaft issue. I took it to Merz dealer and they said it’s known issue of soft metal sproket internal to engine that occurs often. Many times at 50k miles but I bought my car at 150k. Was told engine could stop moving forward at any time.

2007 Mercedes-Benz ML350 DEFECTIVE BALANCE SHAFT CAUSING PAUSE & STOP IN TRAFFIC This is a known defect and has been resolved previously in customers favor in class action and private lawsuits against Mercedes Benz USA. Mercedes refuses to take responsibility for a defective and unsafe build THAT PUTS EVERYONE IN THE PATH OF THIS CARS LIFE IN JEOPARDY. PLEASE FOR THE SAFETY OF THE PUBLIC WILL YOU FORCE THEM TO ISSUE A RECALL ON THE BALANCE SHAFT before I have to get an attorney! Balance Shaft - UNSAFE!! BALANCE SHAFT has made this a suicide/weapon on wheels. When driving the car will suddenly and with no notice lose power, slow down substantially or stop on its own and sometimes will not moved forward at all. This has happened in traffic and I was almost hit. THIS IS VERY UNSAFE COULD KILL ME OR ANYONE AROUND ME. Each time I have had to turn on emergency flashers, turn off the car and restart. I drove home with Emergency flashers on all the way. 2 mechanics, including dealer advise this is a known problem for my year and model. Mercedes knows this is defective workmanship & they putting lives at risk. Now I have NO TRANSPORTATION AS THIS CAR IS UNSAFE. I have been advised not to drive the car.

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
NHTSA complaint #11397247 — an unverified report by a vehicle owner.
VEHICLE WAS SENT TO THE SHOP FOR CHECK ENGINE LIGHT. THE VEHICLE DIAGNOSTIC INDICATED THAT IT WAS THE CRANK SHAFT SENSOR. THE SENSOR WAS CHANGED OUT BUT THE CHECK ENGINE LIGHT IMMEDIATELY CAME BACK ON. AFTER FURTHER DIAGNOSTIC IT WAS DETERMINED THAT THE VEHICLE BALANCE SHAFT LOCATED INSIDE OF THE ENGINE WAS DEFECTIVE AND THE ONLY WAY TO FIX THE PROBLEM IS TO REPLACE THE PART INSIDE OF THE ENGINE. CURRENTLY I CANNOT PASS EMISSIONS OR TAG REGISTRATION BECAUSE OF THIS ISSUE.

MERCEDES HAS PRODUCED SEVERAL THOUSAND ENGINES WITH DEFECTIVE BALANCE SHAFT SEEN IN MODEL YEARS 2005-2007 IN THE M272 AND M273. THE DECIDED USE OF SOFT METALS FOR ENGINE COMPONENTS, SUCH AS THE BALANCE SHAFT, LEAD TO A RAPID DETERIORATION OVER TIME AND RENDERS THE ENGINE UNUSABLE AND A POTENTIAL HAZARD AS THE CAMSHAFT AND CRANKSHAFT WILL NOT TURN, POTENTIALLY CAUSING THE VEHICLE TO BREAK DOWN ON THE ROADWAY, LOSE POWER STEERING OR EVEN LOCK THE STEERING COLUMN, HEAT EXCESSIVELY, OR POSSIBLY EVEN CATCH FIRE. MERCEDES HAS ACCEPTED A SETTLEMENT OFFER IN 2015 COVERING MANY PLAINTIFFS, BUT DENIED RESPONSIBILITY. IT IS OBVIOUS THAT THE CONSUMER HAD NOTHING TO DO WITH THE CHOICE OF MATERIALS USED TO MAKE THE BALANCE SHAFT, AND THEREFORE THE MANUFACTURER IS CLEARLY RESPONSIBLE, AND MUST KNOW IT. UPON REPLACEMENT OF THE BALANCE SHAFT, THE ISSUE SEEMS TO GO AWAY, INDICATING THAT THE MANUFACTURER MADE A FIX FOR AN ISSUE THEY KNEW THEY WERE RESPONSIBLE FOR, COVERED IT UP, AND DENIED RESPONSIBILITY. THE NEWER BALANCE SHAFTS ARE RELIABLE AS MERCEDES KNEW OF ISSUES WITH THEIR PREVIOUS FAULTY ONES. MERCEDES HAS ONLY OFFERED TO COVER UP SOME OF THE DAMAGES, IN MOST CASES LESS THAN 38% OR NONE AT ALL, ONLY GAVE CUSTOMERS A FEW MONTHS TO FILE A CLAIM, AND ALMOST NONE WERE NOTIFIED OF THE ISSUE OR THE SETTLEMENT, AND HAD COME TO REALIZE IT WHEN IT WAS TOO LATE. MANY VEHICLES STILL WELL WITHIN WARRANTY HAVE BEEN AFFECTED BY THE DEFECTIVE BALANCE SHAFT, WHICH MEANS THAT OLDER VEHICLES WITH THE SAME ISSUE PREVAILS ON THE BASIS OF THE INITIAL DEFECT. THE BALANCE SHAFT ISSUE HAS CAUSED MY VEHICLE TO STALL ON THE ROADWAY ON MANY OCCASIONS, AND IN ONE INSTANT, MY VEHICLE'S STEERING COLUMN LOCKED AS A RESULT. I HAVE REACHED OUT TO MBUSA FOR A RESOLUTION, ONLY TO BE TOLD THAT SINCE THE VEHICLE IS TOO OLD, IT'S NOT THEIR RESPONSIBILITY. VEHICLES 3 YEARS OLD HAVE HAD THIS ISSUE. AGE IS NO FACTOR.

PURCHASED A USED MERCEDES-BENZ ML350 FROM A LOCAL DEALER. SHORTLY AFTER PURCHASE, CHECK ENGINE LIGHT CAME ON. BROUGHT IT TO THE DEALER TWICE, THEY SAID IT WAS FIXED BUT NEVER WAS. AS A DISABLED MECHANIC, I PUT IT ON MY SCAN TOOL, FIXED THE ISSUES THAT WERE OCCURRING AND NOW I'M HAVING 2 CODES OF P0016 & P0017 COME UP. I DID A LITTLE RESEARCH, COME OUT FIND OUT THAT IT'S AN INTERNAL ISSUE WITH THE ENGINE.I AM FINANCIALLY AND PHYSICALLY UNABLE TO REPAIR IT MYSELF, NOR SHOULD I HAVE TO. AS IT IS A MANUFACTURES DEFECT.I HAVE DONE SOME RESEARCH AND THERE IS A PENDING CLASS ACTION LAWSUIT.
