Fuel system reportsComplaints are reports submitted to NHTSA by owners and drivers. NHTSA does not verify most reports before publishing them, and a complaint does not establish that a defect exists. Volume is influenced by how many of a vehicle were sold, how long it has been on the road, and how much attention an issue has received.

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.

Crash reported

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. The vehicle returned to normal functionality, but the failure became a regular occurrence. The air bags did not deploy. No warning lights were illuminated. 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. The vehicle was repaired, but the failure reoccurred. The vehicle was then taken to the dealer, who was able to duplicate the failure but was unable to provide a diagnosis. The vehicle was not repaired. After investigating the failure, the contact related the failure to Safety Recall 15S18. The contact also stated that before the control arm failure, upon entering the vehicle and attempting to start the ignition, the vehicle failed to start as intended. No warning lights were illuminated. The vehicle was not taken to the dealer or an independent mechanic. The contact repaired the vehicle herself upon replacing the fuel pump control module. After investigating the failure, the contact related the failure to Safety Recall 16S31. The manufacturer was notified of both failures but referred the contact to the NHTSA hotline for assistance. The failure mileage was 138,000.

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 NHTSA 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.

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.

Failure of the vehicle to restart and idle. Vehicle began to slow down, wouldn’t hold cruise speed setting, while driving on the highway; after exiting the Interstate in rural Colorado, it stalled completely. Dealer diagnosed a fuel pump control module failed and result is car only starts, short 8 second run, and shuts off. Replacement module solved the issue on my Ford Flex. Some Flex and similar models were issued recall for this item. Ford contacted, our Flex vin number is not on the recall as issued.

MY "FUEL PUMP MODULE" ON MY NON ECO BOOST 3.5 SUDDENLY STOPPED FUNCTIONING. THE SAME MODULE WAS RECALLED ON THE ECO BOOST 3.5 ENGINE. I HAD JUST DRIVEN 800 PLUS MILES IN TWO DAYS AND THE ENGINE WORKED PERFECTLY. TWO DAYS LATER, IT WOULD NOT START, WHILE PARKED IN THE DRIVEWAY. A DAY LATER IT STARTED. A DAY AFTER THAT IT WOULD NOT START, AGAIN WHILE PARKED. I GOOGLED THE PROBLEM AND REPLACED THE PART, AND IT HAS WORKED PERFECTLY EVER SINCE. IT WOULD HAVE BEEN A REAL ISSUE IF IT HAD FAILED WHILE DRIVING THROUGH WEST TEXAS DURING THE SUB ZERO FREEZING TEMPS.

I STARTED MY CAR AND THE CHECK ENGINE LIGHT CAME ON. I HAVE HAD NO ISSUES AND THE CAR HAD NOT BEEN DOING ANYTHING DIFFERENT. I HAD IT CHECKED AND I GOT THE CODE P025B. I WAS LEAVING THE NEXT MORNING TO GO TO WORK AND THE CAR WOULD CRANK BUT THEN IT CUT OFF AS SOON AS I GOT OUT OF THE DRIVEWAY IN THE MIDDLE OF THE ROAD. I ONLY HAVE 90K MILES ON MY CAR WHICH IS EARLY FOR THE FUEL PUMP. I ALSO READ THAT SOME OF THE SAME MODEL CARS AS MINE HAVE A FUEL PUMP RECALL. I REALLY NEED THIS TO BE CHECKED BECAUSE IT JUST STOPPED OUT OF NO WHERE. I WAS TOLD BY THE FORD DEALERSHIP THAT I WOULD HAVE TO PAY TO HAVE THIS CHECKED TO SEE IF IT WAS A MALFUNCTION.

2014 FORD FLEX HAS A FEW RECALLS; MY CAR DIDN'T GET THE NOTIFICATION BUT ARE EXPERIENCING RECALL PROBLEMS. MY CAR WON'T START DUE TO FUEL MODULE (FUEL PUMP) THAT HAS BEEN RECALLED. ONE THING WE ALSO COMPLAINED ABOUT IS GAS MILEAGE THE CAR LOST 20%-30% SINCE 2017. FORD MOTOR MANDATED US TO TAKE THE CAR TO THE FORD DEALER ONLY. FORD STATED THEY WOULD PAY ALL COSTS 9/19/19; I ALSO HAD TO PAY TO HAVE THE CAR TOWED TO THE LOCATION. NOW FORD MOTOR COMPANY STATED THEY WILL ONLY PAY A SMALL PORTION OF THE AMOUNT. THE DEALER HAS CONTACTED ME AND STATED THAT FORD MOTOR COMPANY WILL NOT PAY ANYTHING. THE PART HAS BEEN RECALLED ON OVER 75,000 2014 FORD FLEX. THE CAR IS CURRENTLY AT THE DEALER AND THEY ARE PUTTING PRESSURE ON ME TO PAY FOR THE REPAIRS. A REPAIR HAS NOT BEEN MADE. GREG JOHNSON AT FRITTZ FORD RIVERSIDE IS THE CONTACT PERSON THERE ‭+1 (951) 687-2121‬; FORD MOTOR COMPANY ‭+1 (800) 392-3673‬. WE ALSO HAD PROBLEMS WITH DEFECTIVE BREAKS THAT ALSO HAVE RECALLS BUT SUPPOSEDLY OUR CAR WAS NOT AFFECTED BUT EXPERIENCED THE SAME ISSUES AS THE PEOPLE WHO RECEIVED RECALLS NOTICES FOR THEIR VEHICLE.

VEHICLE FAILED TO START, CRANKED CONTINUOUSLY BUT NO FUEL. OUR FLEX HAS A NORMAL ASPIRATED ENGINE. VEHICLES WITH THE ECOBOOST OR TURBO ENGINE HAVE A RECALL ON THE FUEL PUMP ELECTRIC MODULE. I REPLACED THE PART MYSELF AND THE FLEX STARTED IMMEDIATELY. FORTUNATELY, THE VEHICLE FAILED IN THE DRIVEWAY AND NOT DRIVING DOWN THE ROAD FULL OF CHILDREN. THIS COMPONENT SHOULD BE RECALLED ON EITHER ENGINE OPTION ON THE FLEX. THERE ARE NUMEROUS STORIES OF THIS COMPONENT FAILING ON EITHER ENGINE MODEL. IT IS A $50 FIX AND I WOULD URGE ALL FLEX OWNERS TO REPLACE THIS COMPONENT YOURSELVES IF FORD WILL NOT REPLACE IT FOR YOU. FOR LESS THAN A TANK OF FUEL, YOU CAN REPLACE THIS COMPONENT YOURSELF AND AVOID THE POSSIBILITY OF BEING STRANDED WITH A VEHICLE THAT STALLS OUT AND WILL NOT RESTART OR SIMPLY FAILS TO START. HAD I BEEN AWARE OF THIS, I WOULD HAVE DONE THIS ASAP. YOU HAVE NO CONTROL OVER WHERE THIS FAILURE WILL OCCUR, I.E. ON THE HIGHWAY LATE AT NIGHT. THIS COMPONENT NEEDS TO BE RECALLED REGARDLESS OF THE ENGINE. THE REPLACEMENT PART IS THE SAME FOR BOTH ENGINES.
