I AND MY 7 YEAR OLD DAUGHTER AND HER FRIEND WERE ENTERING MY DRIVEWAY ON AUG 14,2006, PAUSED TO OPEN MY GARAGE DOOR FROM THE CAR AND I WAS SLOWLY MOVING IN. ALL OF A SUDDEN CAR WENT OUT OF MY CONTROL IN A FLASH THAT I DID NOT EVEN HAVE TIME TO REACT. IT WENT AND HIT OUR OTHER PARKED CAR IN THE GARAGE WITH SUCH A HUGE FORCE THAT THE SECOND CAR LITERALLY WENT AND TORE THE BEDROOM WALL. OUR SECOND CAR IS BADLY DAMAGED ON THE FRONT, BACK AND ONE SIDE (SCRAPING A POLE IN GARAGE) AND WALL NEEDS FIXING TOO. I TRULY SUSPECT THERE IS SOME MECHANICAL PROBLEM FOR THE SUDDEN/UNINTENDED ACCELERATION THAT LED TO THIS UNEXPECTED BEHAVIOR. SO FAR WE FOUND THE IGNITION GOT JAMMED (COULD NOT START AND HAD TO BE TOWED IN), OTHER THAN THE BUMPER/FRONT DAMAGES. CAR IS STILL IN THE BODY SHOP FOR REPAIRS, ONCE FINISHED IT WILL BE TAKEN TO THE DEALER FOR FURTHER ANALYSIS AND CHECK UP. *NM

WHILE DRIVING A LOUD NOISE CAME FROM THE FRONT OF THE ENGINE. I TOOK THE CAR TO THE DEALER AND THE CRANKSHFT PULLEY HAS FAILED MAKING A HOLE IN THE OIL PAN. THE PULLEY AND THE OIL PAN WERE REPLACED AND FOUND OUT THAT THIS KIND OF PREMATURE FAILURES HAS HAPPENED WITH THIS MODEL. THE DEALER WILL NOT PICK UP THE FULL COST FOR REPAIRS SINCE THE CAR HAD 85000 MILES. I THINK MB REALIZES THAT THEY HAVE AN ISSUE WITH THIS TYPE OF FAILURES BUT WILL NOT DO A RECALL. *JB

1999 MERCEDES ML320 HARMONIC BALANCER. I WAS AWARE OF THE INVESTIGATION BEING PERFORMED AND HAD MERCEDES CHECK THE BALANCER IN JANUARY. THEY SAID IT'S FINE. ON 9/6/04, IT FAILED CAUSING $1500 IN DAMAGE. I WAS NOT INJURED BECAUSE I KNEW NOT TO DRIVE THE VEHICLE AFTER FAILURE. MERCEDES NEEDS TO RECALL THE HARMONIC BALANCER. IT IS FAILING ON MOST VEHICLES AND CAUSING EXTENSIVE DAMAGE.*AK

(1)VEHICLE WAS MAKING A LEFT HAND TURN AND BECAME ALMOST IMPOSSIBLE TO TURN STEERING WHEEL. (2) CRANKSHAFT DAMPENER BECAME SEPARATED AT POINT OF RUBBER VULCANIZED AND CAUSED SERPENTINE BELT TO COME LOOSE LEAVING POWER STEERING TO STOP WORKING ALONG WITH ALL OTHER PULLEYS RUN BY THE SAME BELT. (3) DAMPENER AND BELT WERE REPLACED. (OLD PARTS ARE AVAILABLE) THIS IS AN EXTREMELY DANGEROUS SITUATION THAT MY LOCAL DEALERSHIP SAYS IS HAPPENING VERY FREQUENTLY. NEW TYPES OF REPLACEMENT DAMPENERS HAVE BEEN CHANGED SIX (6) TIMES IN THE LAST FIVE (5) YEARS IN THE PARTS BOOK. SEVERAL LOCAL MECHANICS SAY IT'S A VERY COMMON PROBLEM AND THEY WONDER WHY A RECALL HAS NOT BEEN ORDERED. IT WOULD BE VERY EASY TO FIND OUT HOW MANY CRANKSHAFT DAMPENERS HAVE BEEN ORDERED AND REPLACED BY BOTH DEALERS AND PARTS SALES. AGAIN, LET ME SAY THIS IS A VERY DANGEROUS SITUATION THAT IS VERY COMMON. MY PRIMARY WORRY IS THAT A SMALL PERSON WOULD NOT BE ABLE TO TURN THE STEERING WHEEL IF THE POWER STEERING GOES OUT AS IN THESE BROKEN DAMPENER CASES. I'M A 225 LB MAN AND I COULD BARELY BRING THE CAR TO A SAFE STOP AT ONLY 25 MILES PER HOUR. WHAT WOULD HAVE HAPPENED ON A MOUNTAIN ROAD? PLEASE INVESTIGATE THIS PROBLEM FOR EVERYONE'S SAFETY. THANK YOU!! *LA

I HAVE BEEN AN OWNER OF A 1999 MERCEDES BENZ ML320, BOUGHT USED ABOUT 6 MONTHS AGO. RECENTLY, SOMETHING WENT WRONG ON THIS VEHICLE AND IT STARTED WOBBLING AND MAKING EXTERNAL ENGINE NOISE. SOON, I DISCOVERED THAT THERE WAS A NON-METALLIC PART, A RING, THE SIZE OF A PALM WAS FOUND IN MY ENGINE BAY. I TOOK IT TO MY LOCAL MB DEALER, MERCEDES BENZ OF CINCINNATI OHIO AND RECEIVED A QUOTE OF $3700.00. THE DEALER'S SERVICE MANAGER TOLD ME ITS NOT A PROBLEM COMMONLY SEEN BUT IT SOUNDED LIKE AWFULLY TOO POPULAR AS THEY KNEW EXACTLY WHAT IT WAS WHEN I DESCRIBED ON THE PHONE. THE MERCEDES E320 ENGINE (SUPPOSEDLY 1998 THROUGH MID 2000) CALLED M112 AS WELL AS THE SAME ENGINE OR SUBSTANTIALLY SIMILAR ENGINE ON C280, ML320, E430 ETC., HAS A HARMONIC BALANCER, A RUBBER RING SANDWICHED BETWEEN 2 METAL PULLEY TO ISOLATE THE ENGINE VIBRATION FROM THE REST OF THE PULLEYS BEING DRIVEN BY THE ENGINE. THIS IS WHAT THE SERPENTINE BELT ROTATES ON.OVER TIME, THE POORLY DESIGNED HARMONIC BALANCER PULLEY FAILS, THE RUBBER RING CRACKS, BREAKS OR FALLS OFF, DEPENDING ON THE TEMPERATURE OF THE VEHICLE DRIVING CONDITIONS AND STRESS/LOAD. IT IS TYPICALLY SEEN ON ML320 IN THE RANGE OF 40,000 MILES, BUT IS NOT AS COMMONLY REPORTED AS TYPICALLY IT IS STILL UNDER WARRANTY. ON E320, IT TENDS TO BE AROUND 60 ,000 MILES THOUGH, OFTEN IT COULD BE AS LOW AS 25000 MILES. THE ISSUE IS, WHEN THIS PART FAILS, THE ENGINE TIMING BELT COVER , OIL PAN ETC GET SERIOUSLY GOUGED BY THE ROTATING PULLEY. IN MY CASE THE DEALERSHIP, MERCEDES BENZ OF CINCINNATI IS CHARGING $3700.00 FOR THE REPAIRS. OFTEN DEALER PROFESS INNOCENCE OR LACK OF SIMILAR FAILURE (COMMON ACROSS BOARD, EVERY USER IN MY GROUP MENTIONS THAT THE DEALER SAID 'NEVER HEARD OF IT'.) . THE ISSUE BECOME MORE DANGEROUS AND EXPENSIVE AS WELL, WHEN LESS MECHANICALLY INCLINED PEOPLE JUST KEEP DRIVING UNTIL SOMETHING SMELLS OR MAKES TERRIBLE NOISE ETC., OFTEN RESULTING IN A MIDDLE OF THE ROAD COMPLETE BREAKDOWN AND SEIZE OF THE ENGINE. *LA
