Ford Flex overheating problems

Filed Sep 28, 2026 · Engine · VA

My car randomly over heated ON XXX around 3:23 pm and when I pulled over to a parking lot there was antifreeze pouring out of the bottom front passenger side. I tried to allow it to cool down so that I could safely get it to the shop .5 mile away and the vehicle started to shake and stall and the check engine light came on. I had it towed and inspected at Featherstone Auto, 14523 Richmond Hwy, Woodbridge VA 22191 where I was informed by [XXX] that this is a common issue with Ford Flex where the water pump in inside the engine and fails yet there is no recall for this issue. This is an extremely pricely cost that Ford knows is an issue yet there is no resolution on their end??? That is highly unnacceptable. I have had this car for less than a year, granted it is 13 years old. The safety of my selves and others were put at risk because my vehicle almost stopped in the middle of ongoing traffic due to a well known issue with this vehicle. Prior to this there was no engine overheating message in the 11 months that I have had this vehicle. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

2019 Flex , Odometer reading 58,190. Coolant seen on lower part of engine along with low coolant level. Took to dealership who confirmed the water pump failed and was leaking. We were lucky it was caught early before coolant leaked into the engine, causing the engine to stop while driving and permanently damage engine. There are no warnings for this when it happens (coolant leaking into engine),we were just fortunate to notice low coolant. Because there are no coolant warnings, it can lead to catastrophic engine damage while operating vehicle.There are no guarantees that this will not happen again, only parts are under two year warranty. After research, Ford knew this was an issue with this engine when we bought it, not only on the Flex but same engine on other models, yet continued to sell them. Cost $3,391.71 to repair. Because it is over 5 year warranty no help offered, yet is under 60K miles. There are other complaints regarding this same issue yet Ford continues to not acknowledge faulty design of engine. 2) still waiting for rrecall/repair of backup camera, 3) also waiting-recall/repair for plastic pillar covers. Both of these are under a recall for over a year. the federal safety agency has other complaints of this from consumers.

On Sunday, February 22, 2026, I was driving my 2013 Ford Flex with the driver’s seat heater activated. After a period of use, I began to notice an unusual electrical burning smell inside the vehicle. There were no dashboard warning lights or system alerts. I turned the seat heater off immediately once I detected the smell. I did not initially notice an injury at that time. The following day, I experienced significant pain and discovered burns on my buttocks in the area consistent with seat contact. I sought medical evaluation three days later and was diagnosed with second- to third-degree burns. Prescription treatment was provided. The vehicle has not yet been inspected for the cause of the overheating or odor. Based on the location and pattern of injury, and the timing of the electrical smell while the heated seat was activated, the burn appears to have resulted from a malfunction of the seat heating element.

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.

We were experiencing an intermittent electrical issue where the vehicle would crank but not start every time. The vehicle was towed to the dealership on two separate occasions and the mechanic was unable to properly test the vehicle and/or recreate the problem. After some further research, I found a recall on slightly older VIN numbers for this model Flex. The recall for the Fuel Pump Control Module: Fuel system, gasoline: Delivery: Fuel pump Recall date 2016-08-24 Recall no. 16V621000 Ford Motor Company (Ford) is recalling certain model year 2013-2015 Ford Taurus, Ford Flex, Lincoln MKS and Lincoln MKT vehicles equipped with 3.5L GTDI Ecoboost engines and 2013-2015 Ford Taurus Police Interceptor vehicles. A component within the fuel pump electric module (PEM) may overheat causing a loss of electrical power to the fuel pump. Recall consequence: A loss of power to the fuel pump will cause the engine to stall or prevent the vehicle from starting, increasing the risk of a crash. Recall action: Ford will notify owners, and dealers will inspect the fuel PEM part number and replace the fuel PEM, as necessary, free of charge. The recall began on December 1, 2016. Owners may contact Ford customer service at 1‑866‑436‑7332. Ford's number for this recall is 16S31. In addition, I located a forum of owners who were experiencing the same issues. These individuals either replaced the component themselves or had the service performed by a mechanic. https://www.fordflex.net/forums/viewtopic.php?p=212782&sid=6b719ac74855e58a8f26cce53f76b60f#p212782 We are the single owners of this vehicle, and the miles are low at 38,036. I replaced the Fuel Pump Control Module GA8Z-9D370-A several days ago and it started immediately, without exception or issue. I saved the part in case the federal safety agency needs it for any testing. I would urge the consideration of expanding the coverage of recalls to include more VINs since the risk for engine shutdown could cause a crash.

Vehicle would not start after 3 days of not being started or driven. After having the battery jumped the climate control unit malfunctioned. The heat would not turn off and stayed on full blast. This caused the car to overheat and difficult to drive even with the windows down. When brought to the dealership service center, they replaced the heater blower. This fixed the issue temporarily. Then the heat stopped working and in single digit temperatures the vehicle was too cold to drive. The dealership replaced the resistor. This again became a temporary fix. The heat came back but then the vehicle battery kept draining. Having some type of electrical issue put the vehicle at a possible risk for short circuiting, catching fire etc. This is an ongoing issue with ALL YEARS of the Ford Flex. When the vehicle is jump started this causes an electrical short affecting the climate control system but also the entire communication system. .

While driving, just as I turned my steering wheel; it got very stiff to turn. If I was not able to turn, I easily could have drove into someone's house, pedestrians or hit other vehicles both parked and driving on the road. Especially if I were going very much faster and didn't have as much strength as I do. A week before this happened, I got a quick flash of a message twice that read "AdvanceTrack needs service". But after that ine trip a week ago, it never popped back up and still hasn't. Other than that, no warning lights or codes xan be found. I made it home (less than a half mile away). After having it checked by 2 different mechanics, both said it was the electric steering and told me to check the recalls for my 2013 Ford Flex SEL. I found that my particular VIN did NOT have the 2 recalls that affected numerous Ford vehicles with Electric Steering, including THE SAME YEAR, MAKE AND MODEL of my Ford Flex. The recall is for the power steering. I've also seen numerous other posts on fordflex.net where this has affected many Ford Flex vehicles from 2009 to 2018 with electric steering. The other issue I had is a known recall for other Ford Flex vehicles, but not my VIN, just like the previous. I was driving on the highway when my dash starts beeping and flashing at me wiyh an overheating issue. I had to do my best to get off the highway. Thankfully I was stopped when this happened and not far from the turn I needed to get me and my car to safety. Turned out to be the internal water pump. It cost me around $2,000.00 to get it fixed.

Traveling along the interstate at regular speed, the engine began to overheat. A leak from the water pump occurred and flooded the engine and oil reservoir causing the vehicle to immediately smoke and overheat. After allowing the vehicle to sit and cool down so not to start a fire when the hood is lifted, the damage to the engine took place. The head gasket blew and antifreeze mixed in with the motor oil.
