   On February 26, 2026, I purchased a used 2009 Ford Flex VIN from Header’s Auto Sales. At time of delivery, the vehicle was equipped with tires that did not meet the manufacturer’s required load rating for this vehicle. A licensed mechanic provided a safety assessment confirming the tires were improperly load-rated and unsafe to carry the vehicle load. We were not informed of this issue at sale. To make the vehicle safe to drive, I replaced all 4 tires at my cost. Improper load-rated tires can result in tire failure, loss of vehicle control, and crash. Dealer sold vehicle "as-is" without disclosure of this safety defect.

   You can be driving down the road, and all your gauges will stop working, and all the warning lights on the dash will light up. The first time this happened my wife got stuck at a gas station all the warning lights were on and the car would not start, people tried to jump it and it would not affected at all. I looked on the internet and found were someone said to beat on the passenger side floorboard, I called my wife and told her to try that, and when she did the car would start. It doesn't do it all the time, you never know when it's going to happen. We have to just stomp on the passenger floor to get everything to start working again. If I had not found this information from somebody else on the internet my wife would have been stuck about a hundred miles from home. I've taken it to the Ford house and they say they've never heard of anything like this but I know it's happened before two other people that's how I knew to stomp on the floorboard on the passenger side.

   Rear subframe rusted at bolt mount. Vehicle could have experienced catastrophic failure wihle driving. Independent service center diagnosed and documented rusted area and potential for failure. Noise would happen during acceleration/deceleration but not in wet weather conditions. Until diagnosed as unsafe to drive, vehicle drove with rear passenger side sitting on rear spring, potentially causing spring to rust prematurely.

   The door ajar sensor malfunctions and is crazy expensive to fix. There are numerous posts and videos online of workarounds bcz it’s so common but they don’t seem safe since that’s a safety feature and the workarounds are simply a way to trick or bypass the warning sensors since the doors are actually closed in most cases. Ford needs to take ownership of this and issue a recall. There’s a tire pressure sensor failure as well.

   Was driving and the steering wheel became stiff. I received no warnings indications or lights on the dash. I had to give it a hard turn to get it to a parking lot and have it towed to a dealership.

   While driving around February 20th, 2022 we started swerving uncontrollably and almost ran into the curb and flipped while going about 40 MPH. My husband put on breaks but it felt like we were sliding on ice....without any ice on the road. We almost flipped and were very shaken, and lucky. We got vehicle to Firestone and they said our left rear toe link had broke. Supposedly our vehicle year is not part of the recall, I think it should be. Thank you

   The contact owns a 2009 Ford Flex. The contact stated that after refueling the vehicle, the odor of fuel was present coming from the vehicle. After parking inside the garage, there was fuel leaking from the seam of the fuel tank on the passenger’s side. The cause of the failure was not yet determined. Also, while attempting to stop the vehicle, the brake pedal would extend to the floor and the vehicle would not immediately stop. The contact determined that the brake booster was faulty and needed to be replaced. The vehicle was not yet repaired. The manufacturer and an unknown dealer were notified of the failure. The failure mileage was approximately 160,000.

   My Flex has repeatedly lost power while driving. I can feel the car lose power, and the yellow wrench light comes on. After reading up on it, I learned that you have to turn the vehicle off, wherever you are, and restart it after a few minutes. The wrench light turns off, and the car runs as normal, with no records of codes. This is talked about over and over in online forums. The safety issue is that it has happened on the freeway several times while traveling at a high rate of speed. The car loses power, and you cannot accelerate. You have to find a way to stop immediately, put the car in park (and listen to the transmission clunk) and turn it off. This last instance put me in harms way on the freeway. The car lost power while traveling 70mph. I immediately lost speed and had to cross 3 lanes of traffic to pull over to turn the car off. All of the forums talk about the throttle body, but everyone says that’s not the issue. The OSS and TSS sensors are also discussed. The dealerships cannot find out what’s wrong because once the car is turned off and restarted, any codes are erased. The issue persists, and the car keeps losing power wherever and whenever. I am referencing the most recent incident on this form, however, this has happened at least 12 times since September, 2020. Please, please force a recall on this issue!

    LAST NIGHT, I WENT TO BACK THE CAR OUT OF THE GARAGE AND WHILE IN REVERSE, THE ENGINE STARTED REVVING UP UNCONTROLLABLY AND EVEN THOUGH I HAD MY FOOT ON THE BRAKES, IT KEPT MOVING IN REVERSE. I QUICKLY PUT IT IN NEUTRAL AND THE REVVING CAME DOWN. SHUT DOWN THE CAR, RESTARTED IT AND THIS TIME, I PUT IT IN DRIVE AND THE SAME THING HAPPEN AGAIN ONLY TO START LUNGING FORWARD EVEN WHILE BRAKING. IF I WERE IN TRAFFIC OR AT A STOP LIGHT OR SIGN, I WOULD HAVE SURELY HIT THE PERSON(S) IN FRONT OR BEHIND ME. LATER MY WIFE EXPLAINED TO ME THIS HAPPENED WHILE DRIVING ON THE INTERSTATE AND SHE HAD A HARD TIME CONTROLLING THE SPEED, DUE TO REVVING, EVEN WHILE USING THE BRAKE. SHE MANAGED TO TAKE AN EXIT RAMP INTO A LARGE PARKING LOT USING EXTREME BRAKING (FORCEFUL) AND SHUT THE CAR OFF. SHE WAS ABLE TO MAKE IT HOME SHORTLY THEREAFTER. I WAITED UNTIL AFTER 8PM TO DRIVE WHEN THERE WAS LITTLE OR NO TRAFFIC TO DRIVE TO THE CLOSEST CAR REPAIR SHOP TO DROP IT OFF AND THERE HAPPENED TO BE A MECHANIC LEAVING AS I WAS PULLING UP. I DESCRIBED THE PROBLEM AND HE MENTIONED THAT IT WAS A DEFINITELY A SAFETY ISSUE AND ADVISED NOT TO DRIVE IT UNTIL IT GOT DIAGNOSED & REPAIRED. I'VE OWNED A LOT OF CARS IN MY LIFE AND EXPERIENCING UNCONTROLLABLE REVVING WHILST THE TRANSMISSION IS ENGAGED IS A FRIGHTENING EXPERIENCE. LUCKILY WE KEPT OUR WITS AND WERE ABLE TO RECOVER. I ALSO SEE WHERE THIS HAS ALREADY BEEN REPORTED ON THIS SITE. THIS IS A REAL SAFETY ISSUE AND I'M THANKFUL NO ONE WAS INJURED LAST NIGHT, INCLUDING MY WIFE AND CHILDREN. PLEASE, PLEASE CHECK INTO THIS AS THIS IS NOT NORMAL BEHAVIOR AND A SERIOUS SAFETY CONCERN.

    THE VEHICLE OVER HEATS, AND JUST GETS TOO HOT. IF THE A/C IS RUNNING IT OVER HEATS JUST SITTING AT THE LIGHT. NOW THAT IT IS COOLER, THE HEATER IS ON AND IT OVER HEATS JUST SITTING AT THE LIGHT. I STOP THE CAR AND LET IT COOL DOWN BUT IT SHOULD NOT BE OPERATING LIKE THIS. THERE ARE MANY PROBLEMS DESCRIBING THIS SAME PROBLEM AND IT IS A FACTORY DEFECT AND NEEDS TO BE CORRECTED. NO REASON JUST SITTING AT A STOP LIGHT FOR THE CAR TO OVER HEAT.

    WHEN DRIVING DOWN CITY HIGHWAY OR CITY ROADS THE ALL OF THE LIGHTS ON THE DASH BOARD WILL CUT OFF, (IE. RADIO, BLINKERS, HEAT & A/C CONTROLS) WILL SHUT OFF AND THE DRIVE CONTROL BUTTON WILL APPEAR WITH THE DOOR AJAR AND BRAKE LIGHTS. IT IS NOW STARTING TO MAKE A DINGING SOUND WHILE YOU DRIVE AS WELL AS SMELL LIKE SOMETHING IS ON FIRE. THE CAR IS COMPLETELY SHUT AND SEALED. THERE ISN'T A TIME OR INSTANT WHERE THIS IS HAPPENING. IT WILL JUST GO IN AND OUT! FORD YOU REALLY NEED TO FIX THIS PROBLEM SINCE FAMILIES ARE USING THESE VEHICLES. I'VE DONE SOME RESEARCH AND SEE THAT IT IS A COMMON PROBLEM WITH THE 09 FLEX.
