“The car was used in the morning and worked fine. It was parked in the driveway and sat for under an hour before we turned it back on and tried to turn on the heated seats when we realized the touch screen no longer worked and would not respond to touch at all. …”

NHTSA complaint #11222927, filed 2019-06, 70,000 miles

“On july 5, 2018 I was driving at 35 MPH on a city road when a warning light with the words steering assist fault, service required suddenly came on and the steering stopped working almost entirely. There was very little manual ability to steer the car. Fortunately we were on a very wide, empty road, so I was able to use both lanes and get the car to my house. If this had occurred on a busy city street or narrow lane, with any kind of traffic, we could have easily been in a serious, even fatal collision. …”

“My 2015 Ford FLEX was exhibiting symptoms described in the Ford safety recall 16s31. The engine stalled while driving with no warning 5 times over the past two years of ownership with the most recent occurring on 6/20/2019 at 8:15 am. Each incident was at different speeds (30 - 70mph) but no warning prefaced the stall and you had to cut the power off and turn it back on for the car to start again. Two of the stalls were during turning operations while others were while driving straight. On other occasions the engine did not start via remote start, however no dates recorded. …”

“I took it to russell and smith Ford in houston, tx. They said the battery was the issue. A week later same problem, it cranks but wont turnover. It is now at sterling mccall Ford in houston with the same problem. I will attach their diagnosis. I have 57, 000 miles only on this vehicle. I hope that this will all go out to all Ford dealerships..thank you”
