While driving down the highway, a wrench appeared on the display, then the speedometer went down to zero and the truck wasn-??t shifting or accelerating. I took it to the Ford dealership and the diagnosed it as an issue with the Leadframe sensor assembly. They also let me know this is a known issue and there was an extended warranty program that my vehicle is over mileage for. The repair cost estimate was $800 for parts/labor. They also stated that the part is on back order and may be a month before they could get it. When I asked about driving with the issue they said it won-??t do damage to my transmission but may intermittently cause shifting issues and could result in loss of reverse. I don-??t feel comfortable driving it like that but it is my only vehicle. I also contact Ford customer care directly but there was nothing they could do to assist and pointed me here.

I was driving at approximately 30 mph when the transmission's OSS (Output Speed sensor) suddenly malfunctioned, causing an unexpected downshift into first gear. This abrupt shift led to a loss of control, resulting in a harrowing collision with a tree. What I witnessed next is etched into my memory forever: a scene of blood, fluorescent white bone fragments, and shattered glass strewn all around. Bones were even protruding through my skin at various locations, including my wrists, forearms, legs, and ankles, not to mention the dislocated shoulders. Thankfully, there were no other individuals present at the scene; otherwise, the outcome could have been equally disastrous, if not fatal, for them. Astonishingly, there were no discernible warning signs such as unusual sounds or dashboard warning lights prior to this incident. Following the accident, my pickup truck was towed to Cedar Park Wrecker, only to be swiftly claimed by the insurance company and subsequently sent to auction within a matter of days.

Illuminated wrench light followed by malfunctioning speedometer, cruise control, & turn signal cancellation. Delayed and no gear shifting including an unexpected transmission downshift to 1st gear occurring at 40 mph: rear wheels locked up, engine revved to redline, had to put hazard flashers on and shut engine down in heavy moving traffic. Finally Check Engine/Malfunction Indicator Light (MIL); later reading P0720 code.

The vehicle would down shift aggressively into first gear. The speedometer and gear displays would not function showing 0mph while driving. The vehicle would move through gears erratically. Driver and passengers would be jerked forward.The vehicle has been inspected by an authorized Ford dealer. There were no indicator lights at the start of the issue. Indicator light appeared after multiple incidents spanning over a few months.

I was running 65mph and my truck down shifted from 6th to 3rd. I called my dealer and they said they never heard of this problem so I called two more and can-€™t get any answers. Glad no one was behind me.

Vehicle shifts from a high gear to a low gear. While driving 60 miles an hour on the expressway my F150 went from six gear to first gear with no warning locking my rear wheels causing my speed to drastically or abruptly be lower almost causing several other vehicles to crash into the back of my pick up. Vehicle stays on gear sometimes first third or fifth gear with no warning switching back-and-forth. While making a stop at 0 mph vehicle stays at a high gear for example he could stay at third gear or fifth gear so they takeoff will be in third or fifth gear not in first gear. Also losing speedometer reading. This has happened multiple times while driving at low speed or high speed. I am concerned that this could cause accidents in the roads. Ford motor company corporate advised me that is an auto pocket fix sensor customer satisfaction program has expired for my vehicle. I never received notification of this issue while on my truck was within warranty. Ford Motor Company stated that they extended their coverage until 10,000 miles or 150,000 miles whichever comes first. My vehicle has 165,000 miles and he-€™s 10 years old. I don-€™t believe this is a normal Tear and water failure. This is a manufactures defective part that has happened in thousands of vehicles is not an isolated incident.

While driving at approximately 60mph my vehicle shifted into first gear and aggressively skidded into oncoming traffic with my wife and two daughters in the truck. After regaining control, I drove it to my residence where the issue was repeated two times at slower speeds. After calling my local Ford dealership, they stated that there were two open recalls relating to the issue, 19S07 relating to the PCM and 19N01 relating to the leadframe. Apparently the two issues have resulted in many crashes and multiple fatalities. 19S01 was completed on my vehicle in 2019, however they did not mention or fix the leadframe issues in 19N01 despite it already being an open recall with national attention. I did not receive a recall letter or notification despite the serious nature of the issue. While I was within the warranty window for the leadframe at the time of service for the first recall, I have recently driven past 150,000 miles. The same Ford dealership stated that while the two recalls would apply, they were under a 10 year 150,000 mile warranty. I am within 10 years, but at 163,000 miles. After discussions with my dealership and two customer service representatives at your call center, I am extremely disappointed to hear that this known safety issue will not be fixed on a 9 year old vehicle because I am 10,000 miles outside of your warranty issue.

While driving (at any speed and from any gear) truck frequently, unpredictably exhibits following behavior: - speedometer need drops to zero regardless of actual speed. - truck loses proper shifting functionality. Event has occurred a dozen times or so since 12 December 2020, usually at speeds and gearing above third. Typical result is truck will not downshift below third gear, but on one occasion event occurred at a stop light, and gearing above first would not engage - odometer, trip meter, gas mileage and other digital information displays null out to dashes instead of showing numbers - a wrench symbol appears on right side of the digital display. Symbol sometimes remains for the duration of the event, and sometimes goes away. - sometimes the check engine light appears, sometimes not - airbag light illuminates if I turn the truck off, remove the key, and then re-start, the truck temporarily returns to normal function, with no indication event occurred (check engine light not on, etc). Truck operates normally until it happens again, often within minutes (or even moments) of the reset, but sometimes not again for the duration of a 20 or 25 minute trip. Truck is not safe to operate in this condition and I have now stopped driving it. I have been stuck at a red light on a grade with a load in the bed and traffic behind me, unable to move when the light changes, because first and second gear will not engage, and third gear lacks torque to get moving. Once, after accelerating from a stop, the event occurred and the truck was stuck in first gear, causing unsafe traffic condition (for me and others) while I attempted to pull over safely through traffic. In addition to photos submitted herewith, I have video clips showing occurrence at highway and at surface street speeds. Contact me if you want them.

While driving, either going 25 mph in a housing development or 75 mph on the interstate, the truck will sometimes shift gears, throw a wrench light, and the speedometer will read 0. there has been a recall for an issue similar to this for trucks between 2011 and 2013. Trucks not covered under this recall were given a feild service action for extended warranty. They know this is an issue to more vehicles than what they recalled. Owners were not notified of this field service action. Not only that, but this is very dangerous while going 75 mph on the interstate. This causes the truck to down shift, slow down, and you must pull over for safety on the interstate. A code will pop up as P0720 or P0721. Ford should be doing more since they know it is an issue, or they would not have extended the warranty. This is happening to many F-150 vehicles built in those date ranges.

When driving at a normal highway speed of anywhere between 50 to 75 mph the transmission will down shift to 1st gear. Does not suddenly slow down because the gear returns to 5 or 6th gear immediately. I have had a Ford dealership address the issue by reprogramming the control module on the transmission but I am still experiencing this problem. I believe it to be a high safety risk. The occurrence happens intermittently. So there is no specific date available.

The speed reduced from 50 to 20 and then suddenly stop. The speedometer went to 0 after taking it to do the recall for sudden transmission downshift. Before that it wasn't doing it. Ford does not want to fix it because it's over 150,000 miles, but I just knew about this past recall.

Multiple times while in motion 45mph + (spontaneously), orange wrench comes up on my dash, speedometer drops to zero, engine power is cut to almost nothing, and a few times at higher speeds 60mph +, the wheels lock due to transmission downshifting out of nowhere. This has happened on the loop, city streets, highways, it's random. I can only limp my way to a safe spot to pull over, turn engine off then back on and everything generally starts working again. Last night on a city road doing about 55mph it locked up again but refused to drop out of 5th gear though I was at a dead stop. Even turning the key of and on would not re set it. It finally got to 1st after messing with it and I got it home, hooked it to my obd2 reader and it is throwing a P0720 output speed shaft sensor malfunction code and my check engine light will not go off. I have attached a picture of the code it is now showing, and date of malfunction is most recent.
