2006 Mercedes-Benz E-Class Engine Problems

Certain Mercedes-Benz models 2005- 2007 M272 V6 and M273 V8’s have faced or are facing issues regarding the balance sprocket in which drives the camshaft and crankshaft of the vehicle. Mercedes-Benz had made a decision to make certain engine components out of soft metals, when such metals are not adequate in handling the stress of the engine. In particular, in many cases, the balance sprocket was made with inadequate materials and gradually deteriorated to the point in which it could not engage the timing chain and cause camshaft-crankshaft misalignment. I personally did not experience such failure yet but it is more of a concern as this is a common issue , the repair is quite substantial and the failure can damage the engine even more

Engine codes P0016 and P0017 reads cam shaft and crank shaft correlation it is everywhere on the internet and on the Mercedes Benz Forum.This is a know problem that Mercedes has ignored. its on all 2004 thru 2008 vehicles with the 3.5 engine. Calls for a balancer shaft replacement. This should definitely be a recall issue.The industry knows that is was poorly manufactured part. Your help with rectifying this issue would greatly help the and restore the reputation of Mercedes and restore faith in Mercedes Benz owners. My vehicle is a 2006 E350 4 Matic with only 113,634 miles

We just purchased a 2006 Mercedes for our teenage sons and had a dealer look at it before we purchased it. They told us there were a couple of codes that were worth watching but that it wasn’t anything significant right now. After the car started jerking and shaking while driving it, we brought it in to dealership where they told us it had a common code for Mercedes in this timeframe P0016. Repair estimate is nearly $5000 to replace timing chain and balance shaft, or a new engine which would be roughly the same. After researching on my own upon being told this code, I found all of the information about the class action lawsuit and settlement, which of course we are too late to be a part of. The dealer said there is a potential that the car could just seize up at some point, so I don’t want my young sons to be out on the road when that happens. I am very frustrated and upset that this wasn’t a recall since it apparently affected a huge amount of vehicles manufactured within this time frame. There is a specific list of engines with known issues and ours is among them. Mercedes Benz should be held responsible for making this right because it was definitely a quality issue. Now we are stuck with an unsafe vehicle, or a massive expense due to defect.

Driving the vehicle on several occasions on Interstate 66 and the vehicle spontaneously went into limp mode. Now we find out it's a balance shaft issue and is a known problem from Mercedes in the M272 engines for our 2006 E350 4-matic. They evidently used balance shafts with materials that were too soft, resulting in premature wearing of the balance shafts with all of the M272 engines produced during this time having the problem. There was a previous class action lawsuit, which Mercedes settled, however, the consumers were not adequately notified and no recall was ever issued for the cars. Now we have 2nd or 3rd owners having these problems that didn't get a notice and have no idea there is a huge expensive and dangerous problem with their vehicle. On I-66 traffic moves at 70 mph (regular lanes) or 75 mph (express lanes). Having the vehicle spontaneously go into limp mode because of this engine issue is dangerous and could have caused a fatal accident on multiple occasions for us. Mercedes should be recalling all of these engines and fixing them properly before someone gets injured or killed. When I spoke with Mercedes, they said because I was not involved in the class action suit at that time, they were not willing to fix the car or pay for any portion of the repair, which they quoted me as costing $16,228.96. The problem is the Mercedes went into limp mode on multiple occasions and there was no check engine light to indicate what the problem was for several months. We had no warning that this was going to happen which created a dangerous situation while driving. There were several incidents on different dates spanning months before a check engine light came on with codes and Mercedes could identify the problem specifically was the balance shaft failure.

Balance shaft issues possible cause of vehicle stalls and safety concerns.

The crankshaft pulley is a two piece item. When excessive pressure is on it the pieces separate and disable the car. Upon replacing the belt or belt tensioner more pressure is exerted on the crankshaft pulley. Thus it fails and again disables the vehicle. When doing either of the replacement tasks Mercedes fails to check this or mention it to customers. Thus months later it fails and previous belt replacement of belt tensioner replacement has to be done again. This creates a dual expense without fixing the issue the first time. Expense is in the thousands.

CAR HAD QUARTER TANK WHEN BOUGHT. DROVE OUT GAS AND PUT ABOUT ANOTHER QUARTER TANK OF GAS IN. DROVE THIS OUT. SMELLED NO FUMES. FILLED TANK UP. HAVE SMELLED LOUD GAS SMELL FOR 1 WEEK NOW.

REGARDLESS OF VEHICLE MOVEMENT GAS LEAK FROM FUEL TANK LOCATED UNDER BACK SEAT ABOVE EXHAUST SYSTEM. CONSTANT GAS SMELL, AND FUEL GAUGE ALWAYS JUMPING UP AND DOWN AGAIN REGARDLESS OF MOTION. CHECK ENGINE LIGHTS INDICATE FAULTY COOLANT TEMPERATURE SENSOR, AND FAULTY FUEL LEVEL SENSOR. DEALERSHIP IS REFUSING TO COVER TANK ASSEMBLY REPLACEMENT UNDER PZEV WARRANTY OF 15YRS / 150,000 MILES IN STATE OF CALIFORNIA. VEHICLE IS 2006, WITH 109K MILES. DOCUMENTATION OF TROUBLE CODES NOT AVAILABLE AT TIME OF REPORTING, BUT CAN BE PROVIDED UPON FUTURE REQUEST. FUEL RUNS DOWN THE SIDE OF THE TANK NARROWLY MISSING THE EXHAUST, POTENTIAL FIRE HAZARD.

MERCEDES-BENZ V6 M272 ENGINES HAVE TIMING CHAIN PROBLEMS CAUSED BY BALANCE SHAFT FAILURES WHICH MERCEDES HAS KNOWN ABOUT FOR YEAR. 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. WEAK MATERIALS WERE USED FOR THE BALANCE SHAFT SPROCKETS AND THE TIMING CHAIN GUIDE, MERCEDES NEVER CONTACTED ITS OWNERS ABOUT THE DEFECT WHICH CAN CAUSE THE ENGINE TO HALT AND THE CAR TO STOP MID-TRAFFIC. THE CHECK ENGINE LIGHT COMES ON THE VEHICLE AT EVERY START, THROWING A P0016 AND P0017 TROUBLE CODE, WHICH RETURNS EVEN AFTER CLEARING AND RESTART. AFTER GOING TO SEVERAL MECHANICS, ALL HAVE NOTED THAT THE BALANCE SHAFT (WITHIN THE ENGINE) REQUIRES REPAIR AN ISSUE MERCEDES HAS KNOW ABOUT FOR SEVERAL YEARS, AND HAD EVEN ISSUED ITS MECHANICS WITH SERVICE BULLETINS (APRIL 23, 2009, SEE ATTACHED), BUT HAS NEVER NOTIFIED ITS CAR OWNERS OF THE HAZARDOUS DRIVING DURING ANY OF ITS SERVICE AT THE DEALERSHIP OR HAS NOT NOTIFIED WITH ANY OTHER COMMUNICATION. ENGINES WITH SERIAL NUMBERS LOWER THAN M272 ENGINE SERIAL NO. 2729..30 468993 HAVE THE DEFECTIVE PARTS AT MANUFACTURE, WHICH IS AFFECTING MY MERCEDES VEHICLE.

I ARRIVED HOME AFTER DRIVING 2 MILES FROM WORK AND WHEN I STOPPED I SAW SMOKE COMING FROM THE ENGINE. I TURNED OFF THE CAR AND OPENED THE HOOD. THE SMOKE WOULD ALMOST STOP AND THEN BECOME THICK AGAIN, IN CYCLES OF ABOUT 1 MINUTE. THE SMOKE WAS COMING FROM THE COOLING FAN. AFTER SEVERAL CYCLES IT BURST INTO FLAMES. FORTUNATELY WE WERE READY WITH A FIRE EXTINGUISHER AND PUT THE FIRE OUT RIGHT AWAY. THE FUSE, WHICH I BELIEVE SHOULD HAVE POPPED AND STOPPED THE CYCLING OF THE FAN, NEVER DID BLOW. I BOUGHT MY CAR USED BUT IT ONLY HAS 50,000 MILES ON IT. ALL INFORMATION IN THE CARFAX INDICATES IT WAS MAINTAINED. I DIDN'T TAKE PICTURES OF THE FIRE.

FUEL PUMP LEAKING FUMES (AND FUEL?). WHILE PARKED AND PREPARING TO COME HOME THE FUEL PUMP FAILED AND THE CAR REFUSED TO START. IT WILL NOT BE REPAIRED UNLESS IT IS UNDER THE EXTENDED WARRANTY. I AM TRYING TO LEARN IF IT WILL BE COVERED UNDER A EXTENDED WARRANTY.

TIMING BELT SPROCKET LOST TEETH ON IT DUE TO IT NOT BEING STRONG ENOUGH DEALER NEED TO REPLACE THIS PART SINCE IT PART OF ENGINE THIS PART SHOULD NOT BE GIVING IT LIKE THIS

MY 2006 MERCEDES BENZ 350 E SERIES HAD GOTTEN IN A ACCIDENT DUE TO THE CAR STALLING OUT. I HAVE A CODE READER AND WILL PROVIDE THE NECESSARY PICTURES I TOOK THE DAY PRIOR OF THE ACCIDENT.

I HAVE CHECK ENGINE LIGHT ON, NOBODY "MECHANIC" KNOW TO FIX THIS PROBLEM. I HAVE CODES: 1-P0016 2-P0017 3-P2195 4-P2198 5-P0171 6-P0174

I HAVE A BENZ E350 2006 WITH 60K MILES. MY CHECK ENGINE LIGHT WENT ON AND I WAS TOLD IT WAS THE BALANCE SHAFT GEAR PROBLEM. MERCEDES-BENZ HAD A CLASS ACTION LAWSUIT COMPLAINT FILED FOR THIS ISSUE FOR SOME OF THEIR CARS WITH THIS PROBLEM AS WELL AS FAULTY ENGINES & IDLE GEARS. THERE ARE MORE THAN 100000 CARS FROM 2005 TO 2007 MODEL YEARS WITH THIS PROBLEM AND THEY MANAGED TO GET AWAY WITHOUT ISSUING A RECALL. WHAT SURPRISES ME IS EVEN WITH THE CLASS ACTION SUIT, THEY PAY ONLY 30% OF THE REPAIR COST. DEALERSHIP ESTIMATE FOR THIS REPAIR IS $7500. THEY HAVE TO REMOVE THE ENTIRE ENGINE/MOTOR AND OPEN IT UP TO REPLACE THE SMALL PART. HTTP://WWW.CLASSACTIONREBATES.COM/SETTLEMENTS/MERCEDES_ENGINE/ YOU ARE A MEMBER OF THIS CLASS ACTION IF YOU PURCHASED OR LEASED MERCEDES-BENZ VEHICLES IN THE UNITED STATES THAT ARE MODEL YEARS 2005-2007 EQUIPPED WITH M272 (V6) OR M273 (V8) ENGINES BEARING SERIAL NUMBERS UP TO 2729..30 468993 OR 2739 ..30 088611, RESPECTIVELY. YOU CAN VERIFY YOUR SERIAL NUMBER BY CHECKING YOUR PAST REPAIR ORDERS. CLASS MEMBERS MAY ALSO ENTER THE VEHICLE IDENTIFICATION NUMBER (VIN) ON THE SETTLEMENT WEBSITE TO SEE IF THEIR VEHICLE QUALIFIES FOR BENEFITS FROM THIS MERCEDES CLASS ACTION SETTL I NOW HAVE TO REPLACE THE BALANCE SHIFT GEARS SO MY CAR WILL PASS EMISSIONS INSPECTION. MERCEDES BENZ IS NOT WORTH BUYING. MERCEDES BENZ NEEDS TO BE RESPONSIBLE FOR FAULTY EQUIPMENT. MERCEDES BENZ DOES NOT HAVE THE REPUTATION IT USED TO HAVE.

I WENT TO A HARDWARE STORE AND PARKED THE CAR IN THE STORE PARKING LOT. ABOUT 10 MINUTES LATER SOMEBODY CAME IN AND ASKED ME IF I WAS DRIVING A SILVER MERCEDES; I TOLD HIM YES AND HE TOLD ME THAT IT WAS ON FIRE. WHEN I GOT OUT OF THE STORE I SAW MY CAR'S ENGINE COMPARTMENT ON FIRE. BY THE TIME THE FIRE DEPARTMENT ARRIVED ON THE SCENE THE WHOLE ENGINE COMPARTMENT HAD BEEN GUTTED AND THE FIRE HAD SPREAD TO ANOTHER CAR WHICH WAS PARKED INFRONT OF MINE.

THE ENGINE LIGHT INDICATOR CAME ON AND WAS CHECKED AT THE DEARLERSHIP AND SHOWED TO REPLACE SHAFT. IT SEEMED A LOT OF PROBLEMS WITH SAME INDICATION. COST TO REPAIR WAS QUOTED AT $5,500.

CHECK ENGINE LIGHT GOES ON....CAR VIBRATES (SHAKES!) ...I PULL OVER, STOP THE CAR, TURN OFF THE ENGINE AND THE PROBLEM DOES NOT OCCUR AGAIN ...IN TEN YEARS THIS EPISODE HAS OCCURRED THREE OR FOUR TIMES. I BROUGHT IT IN THE A LOCAL MBZ WARRANTY FACILITY AND THEY COULD NOT FIND ANYTHING WRONG...AND THE PROBLEM DID NOT HAPPEN AGAIN UNTIL 2 WEEKS AGO WHEN I BROUGHT IT TO A DIFFERENT MECHANIC WHO WAS ABLE TO DIAGNOSE THE PROBEM AS THE "INTAKE MANIFOLD ACTUATOR LINKAGE BROKEN" MERCEDES BENZ USA WILL NOT PAY TO REPAIR IT...MY MECHANIC IN SAN DIEGO SAID I WAS THE EIGTH CAR MBZ 2005 TO 2007 THAT HAS HAD THE SAME ISSUE. THE VEHICLE WAS IN MOTION WHEN THE SHAKING OCCURRED. IT HAPPENED BOTH ON HIGHWAY AND STREET ...I WAS NOT TURNING.

ENGINE JERKS AND SPUTTERS WHILE DRIVING. I APPEARS THAT THE VEHICLE WILL SHUTDOWN IMMEDIATELY. CANNOT DRIVE OVER 25 MPH OR GO UP HILLS.

GEARING MECHANISM SUDDENLY FAILED WHILE DRIVING THUS CAUSING THE VEHICLE TO STALL. WAS UNABLE TO MOVE FORWARD UNTIL THE CAR WAS SHUT OFF, RESTARTED AND THEN CAR MOVED FORWARD WITH A VERY JERKY MOTION SITUATION POSED A DANGEROUS HAZARD TO PASSENGERS AS WELL AS OTHER VEHICLES IN THE FLOW OF TRAFFIC. *TR
