On February 26, 2026, I purchased a used 2009 Ford Flex VIN from Headerâs Auto Sales. At time of delivery, the vehicle was equipped with tires that did not meet the manufacturerâs 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…

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 itâs so common but they donât seem safe since thatâs 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. Thereâs 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 passengerâs 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.
