Ford Flex fuel pump problems

Filed Jul 22, 2026 · Fuel system · KS

Hello, I was driving my Ford Flex at 60mph yesterday with my 15 year old friend helping me move. The engine completely died for several seconds and continued running. That night the engine was idling rough which was a new symptom. Today, I made it to my destination and the car died, then it did not start after cranking. The Fuel pump module Aa8a-9d412-ca was faulty and now I am out $142+ from Ford to replace a part myself that is a known problem on the Ecoboost engines for this vehicle. This is a liability and I am seeking reimbursement for this known issue. Please issue a recall for this fuel pump module, everyone's safety is at risk that still has this faulty part installed that Ford has not addressed. Thank you for your time.

The contact owns a 2014 Ford Flex. The contact stated that while her wife was driving at an undisclosed speed, she became aware that the electronic power steering was not functioning properly after the steering wheel jerked in the right direction. As a result, the driver lost control of the vehicle and collided with a dividing wall on the side of the roadway.

A police report was not filed, and no injuries were reported. The vehicle was taken to an independent mechanic, who diagnosed a failure with both control arms.

Driving down road at 45MPH, vehicle lost power, motor quite running. Due to being on 4 lane divided road, and cars all around, I quickly hit my hazard lights, put it in neutral and coasted best I could and was able to turn on a side road to safety. This was very dangerous. Dash lights were on, no warning lights, messages before, during or after event. Tried restarting vehicle and it cranked away. Figured out had to repush the push start button to keep it from cranking away longer. Towed to local Ford dealer. They determined cause to be Fuel Pump Driver Module failed, (explains engine stop since there was no fuel supply, and needed replacement. In addition I had another issue, they found water pump was leaking out weep hole. I then discovered they built the water pump into the engine block, behind the timing chain. It takes 13 hours to replace, and if you don't replace, the water goes into the engine oil. Very bad design, knowing it would need to be replaced. Cost over $2500 and 1 week to change a water pump! Ridiculous. I know a class action lawsuit has been filed-while not a safety issue directly, I think many people will not change it (due to expense), and then the engine blows up while driving creating a safety hazard.

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.

The car completely died in the middle of the road without warning. I had my children In the vehicle. Signs of fuel pump issues, contacted Ford about it and researched Ford flexs have a recall on fuel pumps. My specific vehicle VIN states there are none but all signs and symptoms lead to that. Ford refuses to help with the recall situation just wants me to pay for diagnosis.

Approximately 2 months ago car would not start. Towed to dealer on Friday. Dealer evaluated it on Monday but car resumed starting. Retrieved car. This morning problem returned. Having already done a lot of research on this apparently common issue it seems most of the time it is the fuel pump control module located behind the plastic trim on the passenger side B pillar. A replacement part was acquired from a Ford Parts Dealer and installed into the car. Car starts and runs fine now.
