Steering

32 reports1 crash
“Leaving home to go to the grocery store and as I exited my street a dash warning came on stating "Power Steering Assist" fault Steering wheel locked up making it impossible for me to steer. Fortunately this happened in a spot where there was no other traffic and I was able to just turn off the car and restart and the message was gone and my steering was restored. I am now terrified to drive my car because if this had happened in traffic there could have been a serious accident because steering capability was non existent. . In reading online this is a very common problem with my make and model and apparently there was a recall by Ford for 2011 and later cars but not 2010 even though it is a "known problem" at dealerships. For me this now seems intermittent but in calling the dealership they know of the issue. It would cost me about $2200 to fix. I am happy to provide my vehicle for inspection. Thank you so much for your help ... greatly appreciated”

Engine

30 reports1 fire
“While driving at 65mph, vehicle started to accelerate funny and cel came on. was getting on the freeway and the vehicle overheated and CEL light came on. I was able to safely pull over before the vehicle died. Got vehicle towed to my home and when engine oil was checked, it was discovered that there was coolant in the oil. Took to a local shop where it was determined that the water pump had failed and dumped all of the coolant into the oil pan. Estimated cost of repair with labor is $5,000. Failure mileage was ~192,000. The oil was in good standing and gold in color 12 hours prior and was only driven ~45 miles at highway speeds before the failure happened. From what I can tell, this was a catastrophic failure of the water pump bearing seal that happened almost instantaneously. This needs to be looked into, as the repair bill does not match the issue. A water pump repair should not cost more than the vehicle.”

Electrical system

13 reports
“constant failure of the blend door actuator causes a clicking noise in the cabin upon starting the vehicle, or switching from vent mode to defrost mode. Also happens intermittently when activating the air conditioning. the clicking is loud enough to be heard from outside the vehicle. Unit has been replaced 4 times in 2 years. usually only lasts about a month before the unit starts to click again.”

Fuel/propulsion system

12 reports1 crash
“My 2010 Ford Flex began inadvertently surging forward in acceleration without me making it do this exactly 3 months after I purchased the vehicle. The Ford Dealer was unable to re-produce the problem on several occasions and said my vehicle was fine. No error messages reported in the computer. This has continued to happen sporadically since ownership. I have had another Ford Dealership (as well as an independent mechanic) try and reproduce and diagnose the problem with no luck. Several weeks ago I was driving my vehicle in my residential neighborhood when all of a sudden my car surged forward with great acceleration with no warning. I had to swerve into a driveway and cut the vehicle off to get the vehicle under control. I am 82 and have a heart condition. This safety issue is critical as someone could get hurt or killed. Ford has several complaints of this happening with several models. I believe it is a Ford design flaw in the vehicles electronic throttle system. Ford Corporate was put on notice of these events after the latest safety event. Please, I urge the NHTSA to issue a recall before lives are lost. I can no longer drive this vehicle as I am concerned…”

Service brakes, hydraulic

9 reports
“The contact owns a 2010 Ford Flex. The contact stated that while driving at an undisclosed speed, the brakes seized. There was no warning light illuminated. The contact was unable to pull to the side of the road. The contact stated that the vehicle responded as needed after waiting for a while. The vehicle was taken to an independent mechanic, where the brake master cylinder, the brake booster, the vacuum pump, the brake calipers, the brake check valve, the brakes lines, and the brake pedal sensor were replaced. Additionally, the ECM was replaced and reprogrammed; however, the failure persisted. The contact stated that the failure occurred when the brake fluid was hot after driving 15-20 miles. The dealer was not notified of the failure. The vehicle was not repaired. The contact related the failure to an unknown recall. The manufacturer was notified of the failure and a case was opened. The failure mileage was approximately 102,000.”
