Car just dies in the middle of driving and the steering systemlocks up. There has been a known recall for a fuel control module on Ford Flex, there is also known fuel pump problems with Ford makes and models. I have lost power twice. Had at the mechanic last month. Could not get it to die for an entire week in the shop. Now it is dead in a parking lot again.

I was driving down main street when my car stopped accelerating. I was able to move to the median turn it off and back on, but it still would could I putted across 2 lanes of traffic. Parked on a side street, turned it off and let it sit for a minute. I restarted and it drove fine. It did this exact same thing 2 days before. A yellow wrench appears on the dashboard as the issue is happening, but is not present any other time. The vehicle has around 80,000 miles on it. I am calling Ford today.

Vehicle shut off while pulling away from a stop light. Pulled to side of road and the aa8A-9D412-ca fuel pump relay was extremely hot and vehicle would crank but not start. Pulled connector and let the relay cool. Reinstalled connector and vehicle started with no issues. When I returned home I ordered a new relay and replaced the unit. Vehicle was in a dangerous situation with traffic around. This could have caused an accident.

2 issues 1) the front passenger door though closed is read as a warning "door ajar". the warning stays on at all times. It drains the battery and I have replaced the battery once since owning the 2013 Ford Flex when purchased in 2016 with just under 20,000 miles on it. The interior lights stay on from starting the engine until accelerated speed. The interior lights after parked stay on for a minimum of 30 minutes though it could be longer contributing to draining the vehicle battery. 2) the vehicle began to feel as if it is pulled while in commute. Not starting right away or shuts down/stalls. It has stalled and not turned over though the lights and radio work. Fortunately this has happened after being parked in my parking spot. It will not turn over, but the next morning it will start. After reading about similar issues for other Ford Flex vehicles last week with my vehicle doing the above action I replaced the fuel pump relay module. Which is located in the rear passenger area between rear passenger door and furthest rear window where the seat belt pulls from I felt I had resolved the issue. However, a week exactly later I attempted to start my vehicle when the exact scenario happened all over again. Vehicle would not start, but lights and radio worked. Left alone overnight I went to start it this morning and it starts. Through out the duration of this issue of stalling, not starting, pulling while in motion as it feels like the vehicle is being jerked there is no check engine light or when checking system the only warning is passenger seat ajar.

I parked the vehicle on the mall parking lot on mid-day of July 11, 2018 in cypress, ca. As I turned on ignition to start the engine, it failed to run. Immediately I suspected that the fuel pump is not supplying enough fuel to the injectors; I called Ford roadside assistance for towing service to the nearest Ford dealership. The service advisor will not cover this broken part -fuel pump control module because the recall only applies to the eco boost engine but not on my Flex which is naturally-aspirated. I left the car for two days which they cannot duplicate the engine failure, so I drove the car home which unfortunately failed to run the next day until today. What will I do with this Ford Flex for me to use?

Without warning the vehicle would not start. It would crank, but not start. Vehicle was in an outdoor public parking lot associated with a restaurant after a very warm day of driving around town on personal errands. Situation occurred after dinner on a Friday evening. A major weekend inconvenience, but the issue is that there is a recall on this problem for same make, model and year vehicle. However, it does not apply to our vehicle even though it is in the same class? recall number: 16V621000, Ford number: 16S31. The problem: "fuel pump driver module". cost to repair: $380.87. Safety issue: Considerable internet documentation where exact same problem has occurred while driving the vehicle presenting a serious safety issue for all on board the vehicle. Recall should cover all class vehicles, not some unidentified privileged subset.

My 2013 Ford Flex won't start again. This happened a couple of months ago. I had it towed to the dealer and they said there was a vapor lock issue. They fixed it for $140 plus dollars and yet, here I am again with the same issue. The dealer also stated my VIN was not included in the fuel pump recall list. This time around, I had run a few errands after attending my child's school event, came home and attempted to start the car about one hour later. It was a warm day (around 88 degrees). I can't tell you how frustrating this is. With kids, I need

The contact owns a 2013 Ford Flex. While stationary, the vehicle would not start when prompted. After the first failure, the contact installed a new battery and reset the computer software in order to get the vehicle to restart. Upon the second occurrence, the vehicle was towed to an independent mechanic where it was diagnosed that the fuel pump and the fuel pump module needed to be replaced. A dealer was not made aware of the failure. The manufacturer was made of the failure. The contact cited NHTSA campaign number: 16V621000 (fuel system, gasoline) as the cause of the failure, but the VIN was not included in the recall campaign. The failure mileage was approximately 110,000.

My car is affected by the same recall as many other Ford Flex vehicles, however, my vehicle is not listed as part of the recall. I am having issues with the fuel pump control module of my vehicle and it will not start. It cranks and acts like it wants to start however it will not start due to the lack of fuel created by the fuel pump module.

2013 Ford Flex would turn over just fine (battery was fine) but would not start. It acted like it was not getting any fuel (which was the case). Fortunately, I was not driving at the time as that would have been a potentially serious situation. The dealership replaced the fuel pump driver module (part #aa8Z 9D370 B) which is under recall for other models of my vehicle but not mine. After researching the internet, this is a prevalent issue and should be addressed for all engine models (not just one).

  • 80,000 miles
2013 na 3.5L fired Flex fuel pump control module (part # aa8Z 9D370 B) failure has led to me being stranded 3 times and caused the vehicle to stall twice (once while in motion). Ford has recalled the 2013-2015 Ford Flex with the 3.5L ecoboost (turbocharged) engine for the same issue (fuel pump control module failure/replacement), and uses the same part in both vehicles (part # aa8Z 9D370 B). Vehicle failed to start when parked 3 separate times, resulting in it being towed to a dealership twice. Vehicle stalled once while stationary, and once while in motion without warning. Dealer indicated that the fuel pump control module is at fault and not under recall. Ford openly recalled the turbocharged Flex for the same part that has failed in the naturally aspirated version that I have.
