2013 Ford Flex: won't start

Filed Jan 4, 2023 · Electrical · NH

Vehicle would not start after 3 days of not being started or driven. After having the battery jumped the climate control unit malfunctioned. The heat would not turn off and stayed on full blast. This caused the car to overheat and difficult to drive even with the windows down. When brought to the dealership service center, they replaced the heater blower. This fixed the issue temporarily. Then the heat stopped working and in single digit temperatures the vehicle was too cold to drive. The dealership replaced the resistor. This again became a temporary fix. The heat came back but then the vehicle battery kept draining. Having some type of electrical issue put the vehicle at a possible risk for short circuiting, catching fire etc. This is an ongoing issue with ALL YEARS of the Ford Flex. When the vehicle is jump started this causes an electrical short affecting the climate control system but also the entire communication system. .

I tried starting the car it would start then sputter out very shortly after, after having this occur 3 times the car would not turn over at all and had to get a tow. I had it towed to the dealership, it sat for a day the dealership stated the car started up and they were able to move the car without an issue. They priced the work at $700+ to be completed. The recall number 16v621000 (or 16s31) did not show though it is the same exact issue he described.

Failure of engine to start/run due to a faulty fuel pump control module. Current ford safety recall #16s31 (the federal safety agency #16v621) is limited only to ford/lincoln vehicles equipped with the ecoboost turbocharged engine. The faulty component on my normally aspirated engine, fuel pump control module #aa8z-9d370-b, is the same component being replaced on vehicles affected by the #16v621 the federal safety agency safety recall. To avoid engines shutting off at speed or not starting, it appears that the recall will need to be expanded to include normally aspirated engines as well. We were fortunate because our vehicle failed sitting in our driveway, not at 75 MPH on the highway. My wife's concern is what would have happened to her and our four grandchildren if this failure had taken place on the interstate in busy traffic at 75 MPH. Why is the same component that is failing on ecoboost turbocharged engines being covered by ford safety recall #16s31 not being recalled on similar vehicles equipped normally aspirated engines using the identical component? Failure of the component has the same effect of an engine that cuts off at speed or will not start. Your attention to this matter is greatly appreciated. The safety of the owners of these popular ford/lincoln family vehicles is at stake.

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.

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

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.
