We were on the way back from the grocery store on September 4th, 2021. We were traveling on the freeway at about 60mph when the car suddenly lost power. The only warning light was a wrench on the display. All electrical power remained on but there was no engine power and no acceleration. We were fortunate there was a shoulder where I was able to pull over. I coasted the car down the exit and onto a street away from traffic. I waited about 10 minutes, turned the car off and turned it back on and it started. The wrench light on the display was off. I called the local Ford Dealership and the Service Advisor said there were no recalls and that I would need to pay for a diagnostic check. The issue has not reoccurred.

The power steering system reverts to manual steering mode due to the power steering control module (pscm) detecting a motor position sensor fault. In manual steering mode there is still a mechanical linkage between the steering wheel and the road wheels, allowing steering control to be maintained. When this condition occurs, a message displays in the instrument cluster message center and a chime sounds to inform the driver. Loss of power steering assist requires greater steering effort, especially at lower speeds, which may increase the risk of accident. This has occurred on three occasions. Also see ford recall 15s18.

On october 18, 2019, while entering a parking space at the ikea parking lot, my car experience a loss of power, causing the engine to stall. I tried to start it up about 10 times, and nothing happened - it failed to start every time. After about 2 hours of trying, I finally had to have it towed to my house. When I performed a obd-ii system scan, with my scanner, I got a fault code of p0627 (fuel pump a control circuit) I took the car to the ford dealer, and explained the problem. After two hours, they called me and said their tests revealed no fault codes. Based on the issue I described, they said that if I wanted, they can change the fuel pump, but I would have to pay $100 deductible under the extended warranty plan. The think that may fix the issue of stalling, or not starting. My issue is that if the problem is not fixed, it may increase the risk of a crash, at any given time, and without notice. Given the fact that there are other complaints about this same issue, I think that a general recall for this make/mode/year car should be initiated, before someone loses their life over it.

Our 2015 ford flex recently died when we were driving in traffic, with no warning when we were driving with our 2 young children. The ford flex only has ~45k miles on it and has been serviced regularly. Turns out it is bad part (fuel pump electric module (pem)) that is recalled by ford in the 2015 flex. The recall was started in 2016 and our flex died in 2018. I was told by the dealer and later by ford service that our car is not covered because the VIN is not included in the recall. So while some 2015 ford flexs' had this exact part covered under warranty ours was not. We had to have it towed into the dealer, san tan ford in gilbert az, and then pay them about $400 for the repair. The dealer was great but it is not right ford does not cover this part on our particular car since it is exactly the make, model, year and part that is covered under the warranty. Below is a copy of the recall from the website. Summary: 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: 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.

Vehicle lost engine power while driving on 4 separate occasions, once while at highway speeds. Only fault indicator shown is "wrench" symbol. Upon shutdown and restart, issue resolves itself until it occurs again. There are no symptoms leading up to power loss, and it surprises driver since there is no driveline power, as well as reduced braking and steering capability. This is especially dangerous on the highway and at in traffic. Dealer has stated that since it cannot be easily repeated, that they cannot fix it.
