This began in November of 2022 as an intermittent concern. At first, it appeared that I could temporally correct by pulling over completely shutting off the truck and re-starting (re-booting) but is rapidly becoming worse and today (02/09/2023) became untenable, no matter what I did; the speedometer would not work or behaved erratically for brief periods; the information center display disappeared and then became dashes; the transmission randomly down-shits gears causing the wheels to lock up briefly or does not shift at all, causing engine rpms to spike. While thankfully this has only occurred at speeds below 40 mph, I feel that this is a safety concern for myself and others as operation of my vehicle becomes haphazard and unpredictable and I am very concerned that it may happen at higher speeds causing a crash. While I have not had the "wrench" displayed, I have read the following codes: u0401 invalid data received from ecm/pcm; p0316 misfire at start; p0722 output speed shaft sensor the local dealer sates that he believes it to be a molded lead frame issue that was recalled in previous F-150 models but as mine was a 2014, it was not covered. Obviously, the problem has not been resolved for subsequent models. Additionally, the needed replacement part is unavailable and on indefinite back-order, or as the dealer put it, on "inter-galactic back-order" so now, I have an expensive paper weight in my driveway, waiting for a part that may be months or even up to a year to arrive.
I have a 2014 f150 ecoboost and there is a recall from Ford for a temporary loss of signal with the output shaft speed sensor however not for my year. I tried to go to Ford to have them reflash the pcm like the other years they could not do it I have had my truck go into 1st gear on several occasions while on the freeway at 60+ mph. I have had it stutter in 1st gear and then shift to 5th with the wrench light turning on while trying to pull out into traffic.
