NHTSA lists 1 safety recall and 139 owner complaints for the 2010 Ford Flex. Most complaints involve steering (32) and engine (30). The EPA rates it 18–20 mpg combined.
Ford Motor Company (Ford) is recalling certain model year 2009-2012 Ford Flex, 2008 and 2010-2012 Ford Taurus, 2008-2009 Ford Taurus X, 2008 Mercury Sable, 2009 and 2011 Lincoln MKS vehicles. The driver frontal air bag may improperly inflate during second-stage deployment in the event of a high speed crash. As such, these vehicles fail to comply with the requirements of Federal Motor Vehicle Safety Standard (FMVSS) number 208, "Occupant Crash Protection."
Complaints are unverified owner reports to NHTSA and are not normalized for sales volume. One complaint can cite several components.
“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”
“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.”
“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.”
