Owner report 10031122 · 2003-08-08 (August 8, 2003)

I OWN AN ML 430 MERCEDES BENZ 1999. THE TRANSMISSION FAILED WITH ONLY 116,000 MILES ON IT. I CALLED MBUSA AND THEY REFUSED TO OFFER "GOODWILL" IN ASSISTING WITH REPAIR. THE COST OF REPAIR IS OVER $5,000.00. THE OWNER'S MANUAL STATES THAT THE ML430 SUPPOSEDLY HAS A PERMANENT FILL OF AUTOMATIC TRANSMISSION FLUID SO REGULAR CHECKS AND CHANGES ARE NOT REQUIRED AND FOR THIS REASON THE DIPSTICK HAS BEEN OMITTED. HOW CAN THE CONSUMER BE RESPONSIBLE FOR THIS IF WE CANNOT PERFORM MAINTENANCE ON THE PART? (CONSUMER ALSO REPORTS A RUPTURED BRAKE LINE A…

Owner report 10045578 · 2003-11-06 (November 6, 2003)

THE HARMONIC BALANCER ON THE CRANKSHAFT OF MY MERCEDES ML430 VIN# 4JGAB72E7XA09375 FAILED W/O WARNING CAUSING THE FAN BELT TO FAIL AND THE BALANCER STARTED CUTTING A HOLE IN THE OIL PAN. THIS FAILURE JUST BY "LUCK" DID NOT CAUSE A MOVING ACCIDENT DUE TO LOSS OF ELECTRICAL AND POWER STEERING, OR AN UNDER THE HOOD FIRE. THIS COST ME $500 TO GET FIXED WHEN A $70 PART COULD HAVE BEEN REPLACED IF I HAD ONLY BEEN NOTIFIED OF THIS FREQUENT FAILURE ON MERCEDES MODELS LIKE MINE. THE DEALER WAS LITTLE HELP IN SOLVING THIS PROBLEM.*AK

Owner report 10286165 · 2009-10-03 (October 3, 2009)

THE CHECK ENGINE LIGHT CAME ON AND I TOOK IT TO THE MERCEDES DEALER. I WAS TOLD THAT MY FUEL TANK SENSOR IS BROKEN AND IT NEEDS TO BE REPLACED. MERCEDES DEALERS SELL THE FUEL TANK SENSOR WITH THE FUEL TANK AS ONE UNIT. THEREFORE THE COST OF REPLACEMENT IS ENORMOUS. IN ADDITION AFTER RESEARCHING THIS ISSUE. I HAVE FOUND THAT COMPLAINTS FOR THE ML MODELS AND THE FUEL TANK IS NUMEROUS AND WORTH NOTICING. THIS DEFECT HAS OCCURRED IN THE MAJORITY OF MERCEDES ML MODELS AND THE DEALER ACTUALLY HAS A HUGE INVENTORY OF FUEL TANKS IN ORDER TO PROFIT FROM…
