2007 Mercedes Benz CLS550

DRIVING HIGHWAY SPEEDS AND SUDDENLY VEHICLE JERKED AND LOSSES ALL POWER. ENGINE REVS BUT DOESN'T MOVE. THIS CAN BE A VERY DANGEROUS SITUATION. TRANSMISSION WENT INTO 'LIMP' MODE AND CHECK ENGINE LIGHT LIT. MANY OTHER MERCEDES OWNERS REPORTING SAME PROBLEM WITH THE 722.9 TRANSMISSION VALVEBODY, CONDUCTOR PLATE, AND/OR TCM. THIS SHOULD BE INVESTIGATED AS COUNTLESS OTHER PEOPLE ARE REPORTING THIS SAME ISSUE FOR SEVERAL YEARS NOW.

I AM REFERENCING ACTION # PE12001. AFTER EACH OF MY LAST TWO FUEL FILLLINGS, THE CAR IS EMITTING A VERY STRONG SMELL OF GASOLINE FROM THE BACK SEAT & TRUNK COMPARTMENT. I PARK MY CAR IN MY GARAGE AND THE SMELL IS STRONG ENOUGH THAT I CAN SMELL IT IN MY HOME. I AM EXTREMELY FEARFUL THAT THERE WILL BE A FIRE. I DO NOT DESIRE TO PARK MY CAR OUTSIDE, BUT I BELIEVE THE CAR IS UNSAFE TO KEEP IN GARAGE. I HAVE LOST CONFIDENCE IN MY CAR FEARING THAT EVEN DRIVING IT AROUND TOWN COULD POSE A DANGER TO ME AND MY PASSENGERS.

NOTE THAT THE VEHICLE ON HAS 43,733 MILES - CABIN INTERIOR STRONG LIVE FUEL FUMES - CONSTANT GAS FUMES ON THE INSIDE OF THE CAR CABIN. NOTE THAT THE CAR WAS STATIONARY AT MY RESIDENCE PARKING. I DID NOT KNOW WHERE WERE THE FUMES COMING FROM AT THE TIME. GOT A HEADACHE JUST FOR THE MOMENT I WAS TRYING TO DETERMINED WHERE WERE THE FUMES COMING FROM. THIS IS CURRENTLY FOR ALL DRIVERS AND OWNERS A VERY HAZARDOUS DANGEROUS CONDITION TO ALL EXTREMES, VERY HIGH RISK FROM IGNITION FROM STATIC OR ELECTRICAL, DUE TO WIRE HARDNESS IN THE AREA. VEHICLE WAS TOWED AND TOOK IT TO MERCEDES BENZ DEALER AND FOUND THE FOLLOWING: LEAKAGE IN FUEL SYSTEM. REPLACED FUEL TANK FUEL TANK DRAIN/FILL OBSERVED ACCIDENT PREVENTION REGULATION "12 WL08" FUEL TANK AND FUEL FOR STORAGEBRING OBSERVE ACCIDENT PREVENTION REGULATION "12 WL08" PERFORMED BY MERCEDES-BENZ OF NEW ORLEANS. FUEL TANK LEAKING IN THE INTERIOR WAS FOUND / WAS DRAINED & REFILLED AND FUEL TANK REPLACED. THIS WAS COVER UNDER A NEW SETTLEMENT WITH MERCEDES BENZ AND NHTSA. I THINK THAT THIS SHOULD HAVE BEEN A RECALL WHEN IT RELATES TO SAFETY FACTORS.

MY HUSBAND AND I PURCHASED THE 2007 CLS550 ABOUT SEPTEMBER 2015. WE NOTICED WHEN FILLING THE VEHICLE WITH GAS, WE WOULD HAVE GAS FUMES IN THE VEHICLE SPECIFICALLY ON THE PASSENGER SIDE REAR INSIDE AND OUTSIDE. THE FUMES WERE LIGHT AND WOULD DISSIPATE ONCE THE VEHICLE WAS DRIVEN TO REDUCE THE AMOUNT OF GAS IN THE TANK TO ABOUT THREE-QUARTERS TANK. LAST WEEK WE FILLED THE TANK AND THE SMALL IS NOW STRONGER AND HAS YET TO DISSIPATE ALTHOUGH WE HAVE A QUARTER TANK OF GAS REMAINING. I CHECKED FOR ANY RECALLS ON THIS SINCE WE HAVE NO KNOWLEDGE OF THE VEHICLE HAVING BEEN IN ANY ACCIDENTS, BUT FIND WE DO NOT. THIS ONLINE SEARCH DID NOT REVEAL ANY RECALLS FOR THE GAS FUMES, BUT I NOTED THERE ARE MULTIPLE COMPLAINTS ABOUT THE SAME PROBLEM FOR THIS YEAR, MAKE AND MODEL OF VEHICLE. HAVE ANY PEOPLE DIED FROM THIS, ANY FIRES, ACCIDENTS AS A RESULT? WE HAVE NOT YET, BUT WILL BE TAKING OUR VEHICLE IN FOR EVALUATION OF THE PROBLEM AND WOULD BE ABLE TO PROVIDE DOCUMENTATION OF THE RESULTS IN THE FUTURE. GIVEN THE NAME, I AM SURPRISED MERCEDES IS NOT STEPPING UP HERE! *TR
