Selected complaints filed with NHTSA by 2019 Ford Flex owners, lightly cleaned up (personal details are redacted by NHTSA).
The contact owns a 2019 Ford Flex. The contact stated while attempting to start the vehicle, the vehicle failed to start, and needed to be jumpstarted. Upon replacing the battery and jumping starting the vehicle, the vehicle failed to restart independently. No warning lights were illuminated. The vehicle was taken to an independent mechanic, who was unable to determine the cause of the failure. The contact stated that the independent mechanic replaced the battery and all components connected to the battery; however, the vehicle failed to independently start. The vehicle was not repaired.

The contact owns a 2019 Ford Flex. The contact stated that while driving at 70 MPH, there was an abnormal sound coming from the exterior of the vehicle. The contact pulled over to the side of the road, and upon inspection, the contact became aware that the keypad had detached from the door and was hanging down. No warning lights were illuminated. The vehicle was not taken to the dealer or an independent mechanic to be repaired. The contact taped the keypad to the door to avoid water from entering the keypad. Three-quarters of the keypad had detached and flown off while driving. The buttons on the keypad still functioned as intended. The manufacturer was not notified of the failure. The failure mileage was approximately 110,000.

The contact stated that she pumped the brake pedal and shifted into neutral(N). The vehicle was pushed to the side of the road. The contact's husband arrived at the scene and opened the hood. The contact's husband then noticed that the battery was corroded. …
I have recieved the notice from the manufacturer as expected. I have been notified by my local dealership of the recall. I have attempted several times since notification to have it corrected. I have been told on every occasion the parts were not available. Yet, a bit of searching on Ford's own parts website, I can order the part and have it delivered by Feb 26. At every service visit, the dealership has kindly reminded me of the needed recalls. I question, no parts? Is ford just thinking I will get tired and just stop. No parts in stock should mean, NONE in Ford's entire inventory. The part in question is only used on Ford Flex. No other models use this device. The reserved devices cannot be "for new car builds". I believe we are on the edge of a "BAD FAITH" arguement. An issued "Safety Recall" should not mean "Suggested when you have time Recall.
Back up camera not working; started flashing on/off, turning upside down, and now simply does not work; the beeping still works to let you know you're close but the visual is not available. Not being able to SEE what is behind me is a safety issue as well as not being able to see how close I am to objects. I have taken my Flex to Tim Short Ford Dealership in Morehead, KY where the problem was reproduced. The vehicle has not been inspected by the manufacturer, police, or insurance representative. The warning message that the camera is not available appears when the vehicle is put in reverse. It began approximately 6 months ago.
The back up camera in the vehicle almost never works properly. The majority of the time, while in reverse, the screen is blue or black. It will sometimes show the camera video feed but it will be upside down before the screen turns to black. It will than say that the camera is unavailable. If the back up camera is not operation, it can be very difficult to see small objects or young people directly behind the vehicle. The symptoms are the same as described in NHTSA recall number 24V951 which affects the same vehicle line and model year as this vehicle. This VIN is not affected by recall 24V951.
2019 Ford Flex Back-up camera view is always upside and sometimes delayed or unavailable when the car is put into reverse. Software updates are current. The camera going out, delayed, and being upside down when backing up is definitely a safety issue. There are no longer wheel guidance lines available. The car is 5 years old and the camera worked for about the first two years. There were no warning signs for the problem. Thought a recall would be issued.
Along with problems from the current recalls (that still don't have remedies), our 2019 Ford Flex also has a faulty gas gauge. Not sure what component it would be considered, but even when we fill the tank up with gas, it doesn't register properly how much gas we have in the tank. It shouldn't be a guessing game as to how much gas is in the vehicle. I used to love Fords, but the combination of safety issues is concerning.
Backup Camera functions intermittently. This began at approx 37k miles and 25months of age (vehicle built in June 2019). Backup camera may work, or not, when the vehicle is put in to reverse. This is very similar to the behavior described in other Ford backup camera recalls for other vehicles. Seems like the 2019 Flex should be added. This poses a danger when backing the vehicle.
Backup camera strobing and upside down image. Unable to see pedestrians or other vehicles. Local mechanic suggested replacing camera as possible solution but was unsure if that would help. No warning or other symptoms. First appeared approximately one month ago.
