2010 Ford Fusion Hybrid fuel/propulsion system problems

“ENGINE STALLS WHILE DRIVING AND WILL NOT RESTART. I SUSPECT THAT IT IS RELATED TO SIMILAR ISSUES DRIVERS ARE HAVING WITH THE EVAP CANISTER PURGE VALVE IN OTHER MODEL YEARS: "THE CANISTER PURGE VALVE MAY MALFUNCTION AND CREATE EXCESSIVE VACUUM IN THE FUEL VAPOR MANAGEMENT SYSTEM, WHICH CAN RESULT IN THE ENGINE STALLING WITHOUT RESTARTING. DEALERS WILL REPROGRAM THE POWERTRAIN CONTROL MODULE AND REPLACE THE CANISTER PURGE VALVE AS NEEDED. IF THE VALVE NEEDS TO BE REPLACED, DEALERS WILL ALSO INSPECT AND REPLACE THE CARBON CANISTER, FUEL TANK AND FUEL DELIVERY MODULE AS DETERMINED TO BE NEEDED. ALL REPAIRS WILL BE PERFORMED FREE OF CHARGE TO RESOLVE THE CONCERN."”

“DUE TO A DESIGN FLAW, THE CAR'S COMPUTER SYSTEM CANNOT ACCEPT AN INDICATION OF MORE THAN ONE DIGIT IN THE "AGE" ENTRY. FOR THIS REASON, THE ELECTRIC HIGH VOLTAGE BATTERY STOPS WORKING WHEN THE CAR APPROACHES 10 YEARS OF AGE, CAUSING A SERIOUS AND DANGEROUS HESITATION IN THE DRIVE TRAIN WHEN STARTING FROM A DEAD STOP CREATING A VERY DANGEROUS DRIVING CONDITION, ESPECIALLY WHEN MAKING A CROSS-TRAFFIC TURN. REPEATED REQUESTS FROM MY FORD DEALER TO FORD MOTOR COMPANY FOR AN EXPLANATION OF HOW TO FIX THIS PROBLEM WERE UNSUCCESSFUL. MY LETTERS TO FORD SENIOR MANAGEMENT HAVE GONE UNANSWERED FOR SEVERAL MONTHS. I HAVE SINCE LEARNED HOW TO RESET THE "AGE" DATA, AND MY DEALER HAS FOLLOWED THE INSTRUCTIONS TO ELIMINATE THE CONDITION. FORD SHOULD BE REQUIRED TO ISSUE A RECALL FOR CORRECTION OF THIS KNOWN DESIGN FLAW.”

“MY YELLOW WENCH CHECK ENGINE LIGHT CAME ON,I WAS STOPPED AT A 4 WAY CITY INTERSECTION AND WHEN I STEPPED ON THE GAS PEDAL THE CAR WOULD NOT PICK UP ANY SPEED. I WAS STUCK WITH TRAFFIC BEHIND ME. I HAD TO GO THROUGH THE INTERSECTION AT IDLE SPEED PULL OFF THE ROAD, TURN THE CAR OFF AND WAIT A FEW SECONDS THEN RESTART IT. I WAS THEN ABLE TO DRIVE IT AND THE YELLOW CHECK ENGINE LIGHT WAS NO LONGER ON.THE YELLOW LIGHT CHECK ENGINE LIGHT HAS COME ON BEFORE AND I HAD GOODYEAR AND AUTO ZONE CHECK IT ON THEIR COMPUTER AND IT CAME UP WITH CODE P2135 THROTTLE SENSOR. THE GUY AT AUTO ZONE TOLD ME TO ENTER THAT CODE ON UTUBE AND SEE WHAT OTHER PEOPLE DID TO FIX THE ISSUE. THERE ARE MANY STORIES ON YOUTUBE ETC REGARDING THIS ISSUE. IT SEEMS TO BE A WIDELY KNOW ISSUE AND ON ANOTHER FORD CAR THEY HAD A RECALL FOR IT. I TOOK MY CAR TO THE FORD DEALER AND THEY KEPT IT FOR A FEW DAYS,THEY TOLD ME SINCE THEY COULD NOT GET THE YELLOW LIGHT TO COME ON THEY CAN NOT TELL WHAT THE ISSUE IS AND THEREFORE NOT FIX IT? IT IS DANGEROUS TO DRIVE IT IN THIS CONDITION.”

“MIL COMES ON INTERMITTENTLY WITH A P0451 (3-4 DRIVING CYCLES AFTER A COLD START ) DTC, NO OBVIOUS REPAIR CONDITIONS PRESENT. ROUGH IDLE, POWER LOSS, HESITATION, DECREASE IN MILEAGE. ISSUES GO AWAY ON THEIR OWN AFTER PCM RESET, COME BACK SHORTLY AFTER MIL SETS AGAIN. MIL GOES OFF RANDOMLY, AND PROBLEMS GO AWAY SHORTLY AFTER. HAVE RUN MULTIPLE DIAGNOSTICS AND NO REPAIR ISSUES FOUND. WAS TOLD THE PCM ITSELF MIGHT NEED TO BE REPLACED OR REPROGRAMMED.”

“THE VEHICLE NO LONGER OPERATES IN ELECTRIC MODE, USING THE HIGH VOLTAGE BATTERY TO POWER THE ELECTRIC MOTOR. THIS IS A MAJOR SAFETY CONCERN SINCE THERE IS NO ASSIST FROM THE ELECTRIC DRIVE MOTOR. WHEN ACCELERATING FROM A DEAD STOP, THERE IS A SIGNIFICANT LAG BEFORE THE GASOLINE MOTOR ENGAGES AND PROVIDES ENOUGH POWER TO MOVE THE CAR. THIS IS ESPECIALLY PRONOUNCED WHEN MAKING A LEFT TURN AGAINST TRAFFIC.”

“THE VEHICLE WILL NO LONGER OPERATE IN ELECTRIC MODE. THIS IS A MAJOR SAFETY CONCERN SINCE THERE IS NO ASSIST FROM THE HIGH-VOLTAGE BATTERY POWERED ELECTRIC DRIVE MOTOR. UPON ACCELERATING FROM A DEAD STOP, THERE IS A SIGNIFICANT LAG BEFORE THE ICE KICKS IN AND PROVIDES ENOUGH POWER TO MOVE THE VEHICLE.”
