2010 Ford Flex Fuel system Problems

My 2010 Ford Flex began inadvertently surging forward in acceleration without me making it do this exactly 3 months after I purchased the vehicle. The Ford Dealer was unable to re-produce the problem on several occasions and said my vehicle was fine. No error messages reported in the computer. This has continued to happen sporadically since ownership. I have had another Ford Dealership (as well as an independent mechanic) try and reproduce and diagnose the problem with no luck. Several weeks ago I was driving my vehicle in my residential neighborhood when all of a sudden my car surged forward with great acceleration with no warning. I had to swerve into a driveway and cut the vehicle off to get the vehicle under control. I am 82 and have a heart condition. This safety issue is critical as someone could get hurt or killed. Ford has several complaints of this happening with several models. I believe it is a Ford design flaw in the vehicles electronic throttle system. Ford Corporate was put on notice of these events after the latest safety event. Please, I urge the NHTSA to issue a recall before lives are lost. I can no longer drive this vehicle as I am concerned someone is going to get hurt. It is being towed to the Ravenel Ford Dealership for inspection and diagnosis again.....

2010 FORD FLEX LIMITED ECOBOOST AWD. ELECTRICAL POWER STEERING. INTERMITTENT LOSS OF POWER STEERING WITH NO LIGHTS, NOTIFICATIONS, OR WARNING. FIXED SHORT TERM BY TURNING CAR OFF AND BACK ON AGAIN. VERY DANGEROUS AT LOW SPEEDS, ESPECIALLY WITH THE WEIGHT OF THE VEHICLE AND SIZE OF THE TIRES, SPECIFICALLY FOR SMALLER PEOPLE. RECALL FROM FORD FOR 2011, WILL NOT HELP AT ALL WITH A 2010 FLEX. HAS ALREADY CAUSED ONE ACCIDENT IN A PARKING LOT RESULTING IN DAMAGE TO REAR DRIVER SIDE QUARTER PANEL AFTER STEERING WHEEL BECAME STUCK WHILE REVERSING. FUEL PUMP ALSO NOT ENGAGING, RESULTING IN STALLS AND THE CAR NOT STARTING (NO TICKS, HUMMING, BUZZING, LIGHTS AND RADIO WORK). OVERALL, A VERY DANGEROUS COMBINATION IF THEY WERE TO OCCUR SIMULTANEOUSLY, ESPECIALLY AT SPEED. CAR WAS PURCHASED AROUND 1 1/2- 2 MONTHS AGO. BOTH ISSUES ARE BECOMING MORE AND MORE FREQUENT.

POST RE: FLEX DIED WHILE DRIVING DOWN THE ROAD THURS JUN 11, 2009 6:07 PM THE SAME THING HAPPENED TO MY MOM WHEN SHE WAS DRIVING HERS THROUGH A PARKING LOT, IT JUST STALLED OUT! SHE TOOK IT TO THE DEALER THE SAME DAY AND THEY SAID THEY DIDN'T FIND ANYTHING WRONG WITH IT. THIS WAS ABOUT A MONTH AGO AND SINCE THEN IT HAS NOT HAPPENED AGAIN. I HOPE YOU HAVE BETTER LUCK WITH YOUR DEALER FINDING THE PROBLEM. !@#$%!!!!!!!! IT HAPPENED TO ME TODAY!!!!!!! I WAS ON MY WAY TO A MEETING THIS MORNING AND AS I WAS GOING INTO A CURVE THE CAR DIED!!! KAPUT! DEAD! NO BRAKES, NO POWER STEERING!!!! THANK GOD THERE WAS NO ONCOMING TRAFFIC BECAUSE I WENT STRAIGHT INTO THE OTHER LANE. AND, THANK GOODNESS I HAD READ THIS POST A WHILE AGO SO I KNEW IMMEDIATELY WHAT HAD HAPPENED. I TWISTED THE STEERING WHEEL HARD TO THE RIGHT AND ROLLED THE CAR TO THE SIDE OF THE STREET. PUT IT IN PARK AND RESTARTED IT. IT STARTED LIKE NOTHING. I CALLED MY SA WHO OBVIOUSLY SUGGESTED I BRING THE CAR OVER RIGHT AWAY, WHICH I DID. I ALSO TOLD HIM ABOUT THIS POST AND RICHMONDFLEX'S NOTE ON THE TSB (THANKS BUD!). SINCE I HAD TO LEAVE THE CAR, I'M ALSO HAVING THEM LOOK AT THE BRAKE PROBLEM, WHICH IS BACK. THAT WAS A SCARY MOMENT THIS MORNING!!!! POST RE: FLEX DIED WHILE DRIVING DOWN THE ROAD FRI JUN 12, 2009 3:23 PM IN ANOTHER POST I THOUGHT OUR STEERING LOCKED UP, BUT AFTER TALKING TO MY WIFE, THE SAME STALL HAPPENED TO US (LONG STORY ON THE ACTUAL EVENT). TOTALLY FREAKED HER OUT TO THE POINT SHE WOULDN'T DRIVE THE CAR. I LOOKED UP ON LINE TO SEE IF THE CAR HAD ANY TSBS AND IT STATED WE DIDN'T. I STILL TOOK IT TO THE DEALER (NOT THE ONE WE BOUGHT IT FROM) AND HAD THEM LOOK IT UP AND LO AND BEHOLD THERE IT WAS. THEY SAY THE ISSUE OCCURS AT LESS THAN 10 MPH. THEY REPROGRAMMED THE COMPUTER (IT TOOK 45 MINUTES) AND SAID I SHOULD BE GOOD TO GO. FOR THOSE THAT JUST HAD IT HAPPEN OR HAVE YET TO HAVE IT HAPPEN, GO TO YOUR DEALER, IF NOTHING ELSE FOR THE PEACE OF MIND. MY CAR HAS 2K MILES ON IT. *TR
