Have been waiting for several months for Ford to remedy BOTH recalls. There obviously is no important reason for them to be productive and do the right thing so this issue will likely never be resolved unless I take action and file a complaint. The two issues are not even that critical so I further don't see why action has not been taken. 1. Interior A pillars separating. 2. Back up camera screen on infotainment center.

Wile driving 40 mph, the right rear tire locked up and I had to counter steer aggressively to avoid spinning out and hitting oncoming traffic. The car was flat bed delivered to Ford and they recommended the following repairs. "Control Arm- Rear: rear suspension lateral links. The rear upper and lower control arms not only provide suspension travel but also secure the rear end to the vehicle." "*Tires - 4: passenger rear inner sidewall damaged."

The contact owns a 2018 Ford Flex. The contact stated that while her husband was driving at 75 MPH, the vehicle lost power steering functionality.

The vehicle was towed to an unknown dealer, where it was diagnosed that the steering gear had failed and needed to be replaced. The vehicle was repaired. The manufacturer was notified of the failure. The failure mileage was 75,186.

NHTSA ID 11584056 · filed Apr 19, 2024

WHILE DRIVING THE VEHICLE (IT WAS IN MOTION), ON HWY 290 (NEAR MANOR, TX), THE STEERING ON OUR 2018 FORD FLEX SEIZED UP AND THE CAR WAS IMPOSSIBLE TO TURN. DUE TO COMPLETE LACK OF STEERING, THE CAR WAS AN IMMEDIATE DANGER TO DRIVE AND IT WAS EXTREMELY DIFFICULT TO GET SAFELY OFF THE ROAD, BUT MY HUSBAND WAS ABLE TO DO SO. HE WAS LUCKY TO AVOID A MAJOR COLLISION. THE NEXT DAY WE CALLED FOR THE CAR TO BE TOWED TO THE DEALER. THE TOW TRUCK DRIVER WAS ABLE TO START THE CAR WITHOUT ANY ISSUE. WITH EXTREME MANUAL FORCE APPLIED, THE TOW TRUCK DRIVER WAS BARELY ABLE TO TURN THE CAR ENOUGH IN ORDER TO GET IT ONTO THE TOW TRUCK. ONCE THE CAR WAS RECEIVED BY THE DEALER, THE SERVICE ASSOCIATE CONFIRMED THIS 'STEERING FAILURE' WAS A PROBLEM THEY HAD SEEN COME UP A FEW TIMES IN THE PRIOR WEEKS WITH OTHER FORD MAKES AND MODELS. THEY SAID IT WAS A COSTLY REPAIR AND I SHOULD BE LUCKY BECAUSE WE BOUGHT THE EXTENDED FORD WARRANTY PROGRAM AND THEY WOULD CALL ME LATER TO CONFIRM AFTER A DIAGNOSTIC WAS COMPLETED. LATER THAT DAY THEY CALLED ME AND SAID THEIR DIAGNOSTICS CONFIRMED THE STEERING FAILURE, THAT IT WAS COVERED BY WARRANTY AND MAY TAKE A FEW DAYS AS A MAJOR REPAIR FOR THE STEERING SYSTEM. 3 DAYS LATER, THEY DENIED ANY STEERING FAILURE, AND CLAIMED IT WAS A FAILED BATTERY INSTEAD. DESPITE OUR COMPLAINT, THEY CHARGED US $500 FOR A NEW ONE. AS A RESULT OF THIS SITUATION, WE SOLD THE CAR (AS A DEATH TRAP), CANCELLED OUR FORD EXTENDED WARRANTY AND SOLD ALL OF OUR FORD STOCK. I HOPE SOMETHING IS DONE ABOUT THIS BEFORE THEIR STEERING FAILURES KILL INNOCENT PEOPLE. IF I SEE A FORD ON THE ROAD, I WILL BE GIVING THEM A WIDE BERTH.

I was waiting for my stop light to turn green at 39th street and southwest traffic-way, when my light turned green I started pulling through the intersection. I noticed a car coming towards me on southwest traffic-way at a high rate of speed. I hit the breaks thinking that this person is not going to stop. The vehicle proceeded to run the red light and hit the front passenger side of my vehicle at a high rate of speed and sent my 2018 Ford Flex spinning through the intersection. Not a single airbag went off in my vehicle, that is terrifying to me being a father of 3 young children I am blessed that they were not in the vehicle when the accident happened. The police showed up on the scene within minutes of the accident, the other driver took off running on foot. The police seemed confused as to why my airbags didn’t deploy, as well as the tow truck driver that hauled my vehicle away. The main component that I am reporting is that the airbags did not work or deploy, as a standard safety measure in vehicles I believe that is a big safety problem. The vehicle has been marked as a total loss by insurance.

While driving in a 35mph zone, a complete loss of braking was experienced while coming up to an intersection. The vehicle was unable to stop, not even emergency brake function worked. An independent service center did a postmortem of the brake caliper and confirmed the fastener failure of the caliper bracket. The caliper fasteners sheared off inside the caliper resulting in the caliper piston falling apart while driving. This resulted in complete brake malfunction, and brake fluid leakage. There was no warning or message for this failure. The brakes experienced complete failure without warning.

MY FORD FLEX IS EQUIPPED WITH HANKOOK OPTIMO H426 TIRES. AT APPROXIMATELY 9,500 MILES THE VEHICLE BEGAN TO VIBRATE. I'VE TAKEN IT TO THE SHOP 5 TIMES AND EVERYTHING EXCEPT THE TIRES HAS BEEN RULED OUT. AFTER VISITING A WEB SITE I FOUND LITERALLY HUNDREDS OF COMPLAINTS ABOUT THESE TIRES CAUSING EVERYTHING FROM VIBRATION TO BLOWOUTS. I AM CURRENTLY DRIVING A RENTAL WHILE MY CAR IS IN THE SHOP THAT HAS THE SAME TIRES. IT HAS THE SAME VIBRATION. THE EVENT GENERALLY BEGINS AT ABOUT 60 TO 65 MPH HOWEVER THE VIBRATION HAS BEEN NOTICED AS LOW AS 40 MPH. WHEN IT STARTS AT A LOW SPEED IT TURNS INTO A VIOLENT SHAKING THAT SCARES THE HECK OUT OF ME ENOUGH THAT I PULL OFF THE ROAD AND WAIT UNTILL MY NERVES SETTLE TO CONTINUE DRIVING. TODAY IS FEBRUARY 14 2020. THE VIBRATION HAS BEEN OCCURING SINCE ABOUT OCTOBER 25 2019.

An antifreeze leak is very hard to locate because Ford’s design placed the water pump INside the engine rather than on the OUTside, which would be more the norm. If antifreeze leaks enough, it gets into the oil and the entire engine stands to be destroyed. Our heater quit blowing warm air recently and after intently searching we discovered that we had an antifreeze leak inside of our engine, and antifreeze was slowly leaking out through a weephole in the engine. The water pump had gone bad and needed replacing. The hours required to replace this water pump are intense and they are long. Almost the entire engine needs to be dismantled in order to perform the work. Not only does the pump need changed, but so does the timing chain, hoses, seals, gaskets, tensioners and other engine parts, all at the same time, making this a VERY costly out-of-pocket expense for us elderly people who have long relied on Ford’s standard of doing what’s right by its people. In our research we found that the water pumps in Flex engines are failing, regularly, once the vehicle is close to having 80,000 miles on it. This repair most DEFINITELY should be covered by recall since it is happening so regularly. We have just been forced to pay for this repair on our own and I would like to please ask for your help in recovering what we’ve had to spend. Will you please provide contact information as to where we can reach out for assistance in this matter? Your help is VERY much appreciated! Thank you!
