Hello my check engine light is on in my 2004 Mercedes ml350 so I took it to a Mercedes dealership for inspection and repairs. They kept my suv for 8 days and finally called me back and said they believe the check engine light is on because I need to replace my charcoal canister shut off valve. Now this component takes the gas vapors that has not been burned off and reroutes it through the charcoal canister and back into the engine so it can be burnt off and not enter the atmosphere and enter the inside of the vehicle. Well My suv has failed inspection for emissions and that’s why I brought it in to Mercedes. Well the service department at Mercedes called me 8 days later and said Mercedes does not make that part anymore. And no other aftermarket company makes it either. They charged me $200 to tell me they can’t fix it because the part is not made anymore. So am I safe ? Why Mercedes never recalled a vehicle that can not pass states emissions test. I wrote a letter to the head of Mercedes in Europe and the United States. They offered me $2,000 off of a new Mercedes or $1,000 off a Pre owned Mercedes. Sounds like they know something is not right here. So my complaint is can a car manufacturer stop producing a part that is needed to safely pass the emissions test and isn’t these fumes harmful to me and my family?
CAR SUDDENLY DEVELOPED EXTREME GASOLINE ODOR AFTER A BRIEF 20 MILE TRIP. CURSORY CHECK DID NOT IDENTIFY SOURCE. UPON RETURN TRIP, SAME EXTREME SICKENING ODOR RETURNED. UPON PULLING INTO GARAGE GASOLINE WAS VISIBLY POURING FROM UNDERNEATH THE CAR AND POOLING ON GROUND. IT LOOKED TO BE COMING DIRECTLY FROM GAS TANK AREA BUT COULD NOT DETERMINE MAIN SOURCE AS IT WAS SPRAYED THROUGHOUT THE UNDERCARRIAGE. ASIDE FROM THE NAUSEA, THIS CLEARLY POSED A SIGNIFICANT FIRE DANGER AND WAS IMMEDIATELY TRANSPORTED TO THE DEALER AWAITING REPAIR COSTS NOW. THERE HAVE BEEN NO OTHER INCIDENTS OR EXTERNAL REASONS THAT MIGHT HAVE LED TO THIS (SUCH AS RUNNING OVER SOMETHING OR HITTING SOMETHING IN THE ROAD). AFTER DOING RESEARCH THIS APPEARS TO BE THE SAME TYPE OF PROBLEM THAT HAS BEEN, AND CONTINUES TO BE EXPERIENCED BY OTHER OWNERS DUE TO A MANUFACTURING DEFECT.
DT: THE CONTAC TOWNS A 2004 MERCEDES BENZ WITH 26,933 MILES ON IT THAT CUTS OFF WHEN HE HITTING A BUMP IN THE ROAD. THE DEALER KEPT THE VEHICLE FOR FOUR DAYS. THE VEHICLE WAS TAKEN TO THE DEALER TWICE. ON THE SECOND TRIP TO THE DEALER A NEW HARNESS WAS PLACED IN. THE VEHICLE WAS PICKED UP AFTER FOUR DAYS AND CONTINUED TO SHUT OFF. NO LIGHTS HAD COME ON PRIOR TO THE INCIDENT AND THE STEERING WHEEL DID NOT LOCK. THE VEHICLE IS CURRENTLY COVERED UNDER WARRANTY. THE CONTACT STATED THAT THE DEALER WAS NOT SURE WHAT THE PROBLEM WAS AND THOUGHT THAT IT HAD SOMETHING TO DO WITH THE FUEL PUMP. STARK AQUARIUM PRODUCTS INC. IS THE NAME OF THE COMPANY AND THE VEHICLE IS REGISTERED IN THE COMPANY'S NAME. THE ADDRESS IS: 2914 122ND ST. COLLEGE POINT, NY 11354 *SC *AK
WHILE DRIVING MY 2005 MERCEDES BENZ 350 ALONG ROUTE 1 IN NEW JERSEY, WITHOUT HEARING OR FEELING ANYTHING, MY GAS TANK WAS PUNCTURED. WHEN I STOPPED I SAW A PUDDLE UNDER THE CAR AND FOUND THAT THERE WAS A STEADY FLOW OF GAS FROM UNDER MY CAR. THE FIRE DEPARATMENT CAME AND THE CAR WAS TOWED AWAY. THE ENTIRE GAS TANK WAS REPLACED AT MY EXPENSE SINCE MERCEDES BENZ CLAIMS THAT FUEL TANKS ARE NOT THE SUBJECT OF ANY WARRANTY AND IF THEY ARE PUNCTURED IT IS NOT THEIR RESPONSIBILITY. I FIND IT HARD TO BELIEVE THAT AN OEM IS NOT RESPONSIBLE TO ENSURE THAT THEIR FUEL TANKS DO NOT SPRING LEAKS DURING NORMAL DRIVING CONDITIONS. I WAS EXTREMELY FORTUNATE THAT NO ONE DECIDED TO TOSS A LIT MATCH OR CIGARETTE OUT THEIR WINDOW AS I DROVE BY WITH GAS LEAKING OUT OF THE BOTTOM OF MY CAR. I HAVE ASKED THE DEALER WHO FIXED THE CAR TO SAVE THE DEFECTIVE TANK AND IT CAN BE SENT TO YOU UPON YOUR REQUEST.
