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.

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.

IT WOULD HAVE BEEN A REAL ISSUE IF IT HAD FAILED WHILE DRIVING THROUGH WEST TEXAS DURING THE SUB ZERO FREEZING TEMPS.

Consequence & remedy
Consequence: A fractured rear toe link will cause a sudden change in vehicle handling and increase the risk of a crash.
Remedy: Ford will notify owners, and dealers will replace the rear suspension toe links, free of charge. Remedy parts are not currently available. Owners were notified about the recall on March 3, 2020. A second notice will be mailed when remedy parts become available, which is currently expected to be the end of September 2020. The recall began October 28, 2020. Owners may contact Ford customer service at 1-866-436-7332 or Lincoln customer service at 1-800-521-4140. Ford's number for this recall is 20S04.

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.
Consequence & remedy
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.
Remedy: 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.
Nov 7, 2014
Ford Motor Company (Ford) is recalling certain model year 2014 Ford F-150 and Flex vehicles manufactured March 1, 2014, to May 31, 2014. The affected vehicles were manufactured with a reduced clearance between the seat frame and the seat track assembly. This can cause the Occupant Classification System (OCS) to inaccurately register passenger weight and improperly suppress the passenger front airbag when the passenger seat is occupied by an adult passenger. Thus, these vehicles fail to comply with Federal Motor Vehicle Safety Standard (FMVSS) No. 208, "Occupant Crash Protection."
Consequence & remedy
Consequence: Improper suppression of the passenger airbag increases the risk of an injury to the seat occupant in the event of a crash necessitating deployment of the front passenger airbag.
Remedy: Ford will notify owners, and dealers will widen the gap between the seat frame and seat track assembly and recalibrate the seat OCS, free of charge. The recall began November 25, 2014. Owners may contact Ford customer service at 1-866-436-7332. Ford's number for this recall is 14C10.
Jul 2, 2014
Ford Motor Company (Ford) is recalling certain model year 2012-2014 Ford Edge and Lincoln MKX vehicles manufactured September 2, 2010, to November 30, 2013; 2013-2014 Ford Taurus and Lincoln MKS vehicles manufactured August 25, 2011, to November 30, 2013; and 2013-2014 Ford Flex and Lincoln MKT vehicles manufactured September 12, 2011, to November 30, 2013. In the affected vehicles, the halfshaft retention circlip may not have been properly installed, and as a result, the halfshaft may move outward and disengage from the linkshaft while driving and without prior warning.
Consequence & remedy
Consequence: If the halfshaft and linkshaft become disengaged while driving, power will no longer be transmitted to the wheels, increasing the risk of a vehicle crash. Additionally, if the parking brake is not applied before exiting the vehicle, the vehicle may roll away despite the transmission being placed in 'Park', increasing the risk of injury to exiting occupants and bystanders.
Remedy: Ford will notify owners, and dealers will inspect the vehicles to make sure that the halfshaft is properly retained. If it is not, dealers will replace the linkshaft and also replace the halfshaft if it shows evidence of spline damage, free of charge. The recall began on August 4, 2014. Owners may contact Ford customer service at 1-800-392-3673. Ford's number for this recall is 14S10.
