Example complaints

“I was driving and the car stopped all of a sudden in the middle of residential street at 6 am and when I tried to re-start it, it would crank but would not turn over and start back up so I could move it. I had to push it out of the middle of the street. I had to have it towed to the shop and they said it was the fuel pump control module.”
NHTSA complaint #11315874, filed 2020-03, 56,450 miles“When at idle the FLEX begins to act as if it is going to stall then it does. When I restart it certain electric functions disable. My car is at 54k miles now but we have been having this problem since it was at 32k. I find it extremely coincidental that the same years eco boost engine is having a problem and was issued a recall but not my non eco boost v-6 does not have a recall.”
NHTSA complaint #11243316, filed 2019-08, 54,000 miles“My 2014 Ford FLEX will not start. I came home from work, shut of car. Went out a short time after wards to go out to dinner. Would not start.engine turns over, engine almost starts but doesn't. Fault codes from computer indicate fuel pump control module. Ford has a recall for 2013- 2015 flexes for a potential fuel pump control module failures causing stalling while driving, and engine will not restart. Why is my model not included in the recall?”
NHTSA complaint #11162858, filed 2018-12, 55,000 miles“Vehicle failed to start, cranked continuously but no fuel. Our FLEX has a normal aspirated engine. Vehicles with the ecoboost or turbo engine have a recall on the fuel pump electric module. I replaced the part myself and the FLEX started immediately. Fortunately, the vehicle failed in the driveway and not driving down the road full of children. This component should be recalled on either engine option on the FLEX. There are numerous stories of this component failing on either engine model. …”
NHTSA complaint #11242364, filed 2019-08, 62,098 miles“Car stall and would not start. Replaced fuel pump and working again but my bin was not listed under the recall from what I can see rodors warped 3 turns. Replaced breaks twice within 10,000 miles.”
