2013 Ford Flex: engine stalls while driving

Filed Sep 28, 2026 · Engine · VA

My car randomly over heated ON XXX around 3:23 pm and when I pulled over to a parking lot there was antifreeze pouring out of the bottom front passenger side. I tried to allow it to cool down so that I could safely get it to the shop .5 mile away and the vehicle started to shake and stall and the check engine light came on. I had it towed and inspected at Featherstone Auto, 14523 Richmond Hwy, Woodbridge VA 22191 where I was informed by [XXX] that this is a common issue with Ford Flex where the water pump in inside the engine and fails yet there is no recall for this issue. This is an extremely pricely cost that Ford knows is an issue yet there is no resolution on their end??? That is highly unnacceptable. I have had this car for less than a year, granted it is 13 years old. The safety of my selves and others were put at risk because my vehicle almost stopped in the middle of ongoing traffic due to a well known issue with this vehicle. Prior to this there was no engine overheating message in the 11 months that I have had this vehicle. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

Having problems with the motor stalling out and not starting for days. I'vebparked after filling it up and parking it for the night. Only to go out in the morning and not starting. Then after a few days of sitting it would start.

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.

My ford flex stalls while driving anywhere from 10 MPH (in residential area) to 80 MPH on highway. Electrical is still working the engine shuts off and I lose control of gas/brakes. Three warning signs pop up at the same time: check brake system, collision warning not available, and service advance trac. Once I restart the car, the codes will disappear. The problem was intermittent at first, but now it's occurring more frequently. I'm too scared to drive my car now. Ford isnt being much help. I need help.

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.
