Steering
57 reports1 crash1 related recall
“I have had this vehicle since about August 2025, the brakes and wheel bearings have failed twice, the strut failed, the power steering system has messed up repeatedly, the coolant came FLYING out of the car (while parked) FOR ABSOLUTELY NO REASON! There have been multiple warning lights on since I got the vehicle and I have been told they are just sensors from multiple mechanics and that they don't mean anything. As it relates to the issues, the brakes, calipers, and wheel bearings have given out twice WHILE DRIVING without any sort of warning up until they seized! The strut on the front passenger side has broken for no known reason and the power steering system has been non stop eating power steering fluid with no leaks. Since I have gotten this vehicle, I have put OVER 7,000 dollars worth of work into it. This went to fixing the brake calipers, brakes, rotors, all the steering mechanisms (tie rods, sway bars, etc.) and wheel bearings twice, trying to figure out why coolant flew out of the vehicle for no known reason, trying to figure out where the power steering fluid is going, all to no avail. I have had multiple mechanics look at and check all the…”

“The contact owns a 2011 Ford Flex. The contact stated that while driving at various speeds, the vehicle stalled and lost motive power. The contact coasted to the side of the roadway and had the vehicle towed. The failure occurred intermittently. The contact would make several attempts to start the vehicle to regain normal functionality; however, the failure would recur within several hours or several days. The contact stated while driving at approximately 25 MPH in a School Zone from a stop, the vehicle lost power steering functionality. The vehicle was towed to the residence. The contact stated that the traction control, engine, battery, and ABS warning lights were illuminated. The vehicle was taken to an independent mechanic where it was diagnosed that the power steering box had failed and needed to be replaced. The mechanic had not repaired the vehicle. The vehicle was then taken to the dealer to be diagnosed. The contact was informed that the VIN was not included in a recall. The vehicle had not been repaired. The manufacturer was made aware of the failure, and it was confirmed the VIN was not under recall, nor were the repairs covered under warranty. The…”

“Went to put car in reverse and it kept driving forward- no weird sound or anything. Proceeded to put the car in park and it was still moving forward. Transmission was stuck on drive.The shifter is disconnected from the transmission with no warning .Just looked and the transmission shifter bushing is disconnected. Also saw that this part is a recall on other ford vehicles. Had this been recalled on all vehicles with this part, I would have known to have it fixed. Luckily I was somewhere safe when this happened but it would have put myself as well as others in danger.”
Electrical system
9 reports1 crash1 fire
“I had changed all my bulbs and fuses to my car for my brake lights several times and they still don’t work. My car almost got hit with me and my kids in it due to my break lights not working. Also my car keeps saying service advance trac and keeps saying it every time I drive. My car also keeps running out of power steering fluid every two week I have to add more to keep it from making that loud noise while driving.”
Service brakes
8 reports1 crash
“My brakes locked up suddenly on the rear end causing me to get stuck in the middle of the road and unable to move it, even to tow it. I had to take 2 days almost to fix it in the middle of the road, since yesterday morning. They also began locking up suddenly on the front end, the wheel bearing, CV Joint, Tie Rods, CV Axles, CV Boots, and sway bars began failing out of nowhere as well. The brakes may or may not be able to be replicated, as they are partially fixed and yes my entire front end can be replicated. The danger is my brakes locked up as I was driving, in the middle of the road at that. I have not been able to get the front end fixed as it is expensive, however the danger of this is the tires falling off or the front end failing all together. ALL of the other people who drive these that I have talked to and met have had the same problem and yes they are factory parts! Even the people who have only 30 to 60000 miles on their 2011 Ford Flex Titaniums have these issues! Not only this but also the sensors go bad almost immediately off the lot, which can cause the car to brake without warning, stop running out of nowhere, make the power steering module…”

The vehicle was towed to an independent mechanic to be diagnosed. The contact was informed that water was detected inside the engine and that the water pump needed to be replaced. The vehicle was not repaired. The manufacturer was contacted and stated that the VIN was not under recall. The contact was referred to the NHTSA for assistance. The failure mileage was 146,000.”
