Ford Flex stalling 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)

My vehicle keeps stalling while driving down the road. The vehicle suddenly loses power and stops on the roadway. No indicator lights come on and after several times pushing the push ignition button the car will start. This has happened on several occasions.

In October of 2025 the vehicle began to make engine noises. Within a day the vehicle stalled and shut down completely. I had my mechanic examine the car and they advise coolant had leaked into the engine cause damage. The engine had to be replaced. No warranty coverage and 4k later.

The radio turns on even when the car is off and the keys are not nearby . Sometimes it turns off while driving and will be off for days at a time while other times it just comes on full volume while parked and unattended. Maybe an electrical issue ?

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.
