My 2007 MB ML320 CDI has problem with water entering where spare tire located,after rain or when i use car wash.It builds inside so much water that module for for fuel pump stopped working,all wires were corroded,I paid for repairs from my pocket because MB dealership refused to fix my vehicle even they new MB ML/GL models have issue with water entering spare tire area.Now I find out they have recall with over323,000 ML/GL models.Recall number22v-955.I would like to file this complaint because dealership refuses to cover my previous repairs.Water still entering trunk area,and I have to constantly drain and vacuum trunk area.I hope you will have another recall or add older MB ML/GL to recent recall list.Thanks.
NHTSA complaint #11502631 — an unverified report by a vehicle owner.
THE METHOD IN WHICH A FUEL TANK IS FASTENED TO THE VEHICLE CHASSIS USES A STEEL STRUT TO SUPPORT A SERIES OF STAINLESS STEEL STRAPS. THE DISSIMILARITY IN METALS USED IN FASTENING THE HARDWARE OF BOTH COMBINED WITH EXPOSURE TO THE ELEMENTS WILL CAUSE THE STRUT TO CORRODE WITHOUT WARNING AND THE FUEL TANK TO DROP ONTO THE ROADWAY WITHOUT PRIOR SYMPTOMS OR WARNING. THE CORROSION AT THE CRITICAL FASTING POINTS IS NOT OBVIOUS WITH ROUTINE INSPECTION. WITH MANY OF THESE VEHICLES MANUFACTURED FROM 1998 THROUGH 2005 STILL ON THE ROAD TODAY, OWNERS SHOULD BE MADE AWARE OF THIS POTENTIAL SAFETY ISSUE.

AS I NOTICED IN OTHER COMPLAINTS THEY ALL FOCUS IN THE POWER STEERING ISSUES, FUEL / OIL LEAKS AND LOSS, ESP OPTION , ELECTRICAL MAIL FUNCTIONS THAT RELATE WITH THE ECU, PROBLEM WITH THE SHIFTER. ALL THESE ARE SAFETY CONCERNS SINCE ALL THE ABOVE PROBLEMS CAN CAUSE AN ACCIDENT . I HAVE THE SAME PROBLEMS IN MY CAR AND IT IS REALLY DIFFICULT TO OPERATE THE VEHICLE. THE POWER STEERING IS NOT WORKING AS THE CAR IS NOT IN SPEED MOTION UNLESS YOU USE STRENGTH TO TURN THE WHEEL , THE ESP IS NOT WORKING AT ALL , THE SHIFTER IS NOT CHANGING TO DRIVE UNLESS YOU OVERRIDE IT AND THAT'S THE ONLY WAY TO START IT AND THE FUEL ALONG WITH THE OIL IS LEAKING AND ALL THE FLUIDS ARE DISAPPEARING IN NO TIME . ALL THESE ARE SAFETY HAZARDS AND NOT JUST A SIMPLE PROBLEM . THERE SHOULD HAVE BEEN A REPAIR FOR ALL OF THESE ISSUES ASAP FREE OF CHARGE FROM MERCEDES FOR THE OWNERS OF THE PARTICULAR DEFECTIVE VEHICLES . THANK YOU IN ADVANCE

THIS IS IN REGARD TO NHTSA ID #10033607, ALSO MERCEDES BENZ SERVICE CAMPAIGN #2009100002 DATED JAN 2010, FOR MODEL 163. MY VEHICLE ISN'T COVERED BY ABOVE MERCEDES SERVICE CAMPAIGN BECAUSE IT'S V-6 MODEL, BUT SHOWING EXACTLY THE SAME SAFETY PROBLEM. I'VE TAKEN AND ATTACHED A FEW PHOTOS OF THE PROBLEM AREA SHOWING SEVERE DAMAGE TO FUEL LINE AND LESS SO TO BRAKE LINE. THE PHOTOS SHOWING SEVERE CHAFING BETWEEN FUEL LINE & BRAKE LINE JUST BELOW MASTER CYLINDER. THE SERVICE CAMPAIGN ONLY COVERS 8 CYLINDER MODELS, BUT MY 6 CYLINDER MODEL IS SHOWING EXACTLY THE SAME CHAFING AT THE SAME AREA. I HAVE NOT EXPERIENCED ANY PROBLEM, BUT JUST NOTICED THIS ISSUE LAST FEW DAYS.

MY BATTERY WAS LOW AND UNKNOWN TO ME THE ML320 FOR THIS YEAR LOSES ITS TRANSPONDER CODES IN THE DAS SECURITY MODULE WHEN YOU TRY TO START THE VEHICLE WITH A LOW BATTERY. THIS IS EVIDENTALLY THE THIRD KEY THAT HAS LOST ITS PROGRAMMING ON MY VEHICLE DUE TO LOW BATTERY VOLTAGE. COST SO FAR IS 499 FOR A KEY, WEEKS WAITING FOR THE KEY FROM GERMANY, AND 300 TO PROGRAM IT ONCE THEY RECIEVE THE KEY. ITS A DEALERSHIP ONLY ITEM SO ITS VERY VERY COSTLY. THIS IS A KNOWN PROBLEM WITH MERCADES AND CHECKING THE FORUMS IT SEEMS THAT EVERYONE THAT HAS 1998-2000 MODEL MERCADES ALL LOSE THEIR TRANSPONDER CODES BETWEEN 129,000 AND 132,000 MILES NO MATTER WHAT.THIS IS AN OBVIOUS MANUFACTURERS DEFECT AND A KNOWN ISSUE THAT SHOULD BE PAID FOR BY MERCADES. I NEVER HAD THESE ISSUES WITH MY TWO 2002 ML500'S BUT I WILL NEVER PURCHASE ANOTHER BENZ IN MY LIFE.

WHILE DRIVING, WENT OVER BUMP IN ROAD, AND TRUCK IMMEDIATELY LOST SPEED. PRESSURE ON GAS PEDAL WEAKEND. THERE WAS ABSOLUTELY NO ACCELERATION. I PULLED OVER AFTER ALMOST BEING HIT, AND TURNED VEHICLE OFF. RESTARTED AND PULL OVER INTO AUTOZONE TO HAVE THEM HOOK IT UP TO DIAGNOSTIC READER. IT CAME BACK WITH SEVERAL CODES, THAT ALL STATED "THROTTLE PEDAL POSITIONER MALFUNCTION" I HAVE BOUGHT AND REPLACED THIS ITEM 4 TIMES SINCE THIS INCIDENT, AND THE PROBLEM STILL EXISTS. I AM FORCED TO DRIVE THE VEHICLE BECAUSE I HAVE TO GET BACK AND FORTH TO WORK, BUT I'M ALWAYS VERY AFRAID THAT THIS PART IS GOING TO MALFUNCTION WHILE IN A BUSY INTERSECTION OR STREET, AND I ALONG WITH MY KIDS ARE GOING TO BE KILLED. IT HAPPENS AT LEAST TWO TO THREE TIME A WEEK, SOMETIMES MORE.

THIS CAR SHOULD QUALIFY AS A LEMON. WE SPENT OVER $65K ON IT NEW IN JANUARY OF 2009 AND IT HAS EASILY COSTS US $65K TO KEEP IT RUNNING SINCE. SOMETHING SIGNIFICANT BREAKS ON IT EVERY 60 DAYS SINCE OWNING IT. THE TURBO WENT OUT MOST RECENTLY AFTER A BAD OIL SEAL LET OIL INTO IT. $6500! THE CAR MAY HAVE SADLY BEEN CURSED SINCE DAY ONE. OUR SALES PERSON AT MERCEDES BENZ OF SF DIED RIGHT AFTER WE BOUGHT IT. THINGS STARTED TO BREAK IMMEDIATELY AFTER. PEOPLE RAN INTO IT, ETC. IT HAS BEEN THE WORST CAR OWNER EXPERIENCE IN MY LIFE.

REFERENCE ODI 10457817 I HAVE SINCE RECEIVED A LETTER FROM MERCEDES CORP. STATING THE FUEL PUMP FIRE IS DUE TO AGE AND NORMAL WEAR AND TEAR.

I CANNOT GET RID OF THE VEHICLE RIGHT NOW FOR FINANCIAL REASONS . HOWEVER I DON'T HAVE TO LET MY FAMILY RIDE IN IT. PLEASE HELP BECAUSE THIS IS NOT RIGHT. I HAVE THE LETTER FROM MB STATING THE ABOVE.
NHTSA complaint #10460273 — an unverified report by a vehicle owner.
MY ML320 VEHICLE WAS DRIVEN FOR APPROXIMATELY FIVE HOURS ROUND TRIP THEN PARKED FOR THE EVENING. I ATTEMPTED TO START THE VEHICLE THE FOLLOWING MORNING AND THE VEHICLE WOULD NOT START. AFTER DOING AN EXHAUSTIVE DIAGNOSTIC ON THE VEHICLE. I REMOVED THE FUEL PUMP FROM INSIDE THE FUEL TANK. I SAW THAT THE WIRING HARNESS/CONNECTOR FOR THE HOT LEAD WAS BLACK AND BROWN IN COLOR AND THE PLASTIC AROUND THE HARNESS HAD MELTED. I TOOK PICTURES AND STORED THE PUMP. I EMAILED MERCEDES AND ASKED THEM TO GET BACK WITH ME SINCE MY WIFE AND CHILDREN HAD BEEN IN THE VEHICLE AND THIS IS THE FAMILY VEHICLE. I ALSO READ SEVERAL FORUMS AND COMPLAINTS ON THE INTERNET REFERENCE MERCEDES FUEL PUMPS INCLUDING MY SPECIFIC MODEL. I READ HOW THEY HAVE CAUGHT ON FIRE. I ALSO SAW A PICTURE OF A FUEL PUMP OUT OF A ML 320 IN 2006 THAT HAD CAUGHT FIRE AND ALMOST LOOKED IDENTICAL TO MY FUEL PUMP I HAD REMOVED. I HAVE LOOKED FOR RECALLS AND STILL HAVE NOT HEARD BACK FROM MERCEDES. I AM AT A LOSS ON WHAT TO DO OR IF THERE IS ANYTHING I CAN DO. I WAS TOLD THAT MERCEDES KNOWS ABOUT THIS PROBLEM BUT THAT HEY ARE UNLIKELY TO DO ANYTHING BECAUSE OF THE COST. I WANT TO REPORT THIS IN CASE SOMETHING DOES HAPPEN TO ME AND MY FAMILY. IT WILL BE ON RECORD. THANK YOU FOR YOUR TIME.
