general problems of the 2017 Ford F-150 - part 1

While driving vehicle shifts from 6 gear to first gear on 6r80 transmission amd hard shifts. . Wheels lock upbwhen vehicle downshifts abruptly. . . . . Spoke with Ford mechanic and this is a known issue with lead shield and or speed sensor. . This item need a recalled and repaired. . . No codes are thrown but it is a well know issue. . . Recalls are on 10r80 transmissions lead shield but not 6 speed. Please help.

The transmission downshifted while driving 60 to 65 mph and needed repairs. Transmission specialist changed out transmission electric control unit.

While driving, my 2017 Ford f?150 experienced a sudden loss of the output shaft speed (oss) sensor signal, causing the transmission to stay stuck in a higher gear and triggering the wrench light. The truck lost power and would not shift properly. A diagnostic scan showed two transmission codes: one for the oss sensor and a second code indicating an intermittent electrical signal drop. I contacted a Ford dealer before the repair, described the symptoms, and asked for an estimate. The service advisor did not disclose any known issues and never called me back after saying he would check parts availability. These symptoms match the known failure pattern of the molded lead frame in the 6r80 transmission. My truck exhibited intermittent behavior, harsh shifting, and unsafe drivability. I had to pay $1,250 out of pocket to replace the lead frame to restore normal operation. I later learned that NHTSA has opened an engineering analysis into 2015–2017 f?150 trucks for this exact issue (oss signal loss due to internal electrical degradation of the lead frame). My vehicle’s symptoms, diagnostic codes, and required repair are consistent with the defect under investigation. This failure creates a safety hazard because the truck can suddenly lose the ability to accelerate or shift correctly, especially in traffic or at highway speeds. I am requesting that NHTSA include my vehicle in the investigation and that Ford be required to address this defect.

The powertrain/transmission is not receiving the signal from the engine to accelerate. It can be inspected. The vehicle is slow to accelerate or will not accelerate at all, causing lurching motions and slow movement of the vehicle. This can cause my vehicle to rapidly accelerate or me to slowly decelerate, causing me to possibly run into others or be hit by others. No one has reproduced or assessed the problem. The problem occurred multiple times before a warning message was displayed. The signal appeared after two weeks of the failure occuring.

Drivability issues. Harsh shifting, downshifting, loss of acceleration, and warning lights appearing. Giving code p0722.

Transmission dropped into first gear at 45mph. Rear end locked up while taking my kids to school. Output speed sensor in transmission. Lead frame issue.

6 speed automatic transmission downshifts while traveling at high speed into low gear by itself, causing vehicle to change speed and lock up rear wheels. Very dangerous! vehicle has 66,150 miles on it, and isn’t used for work. The transmission also shifts into second and third gears while sitting still at a traffic light. This has happened multiple times. It is just now 1 month out of service contract (ended 8/2025 it started 9/2025). It is available for inspection. It has not been to dealer or mechanic yet for inspection or repairs to this certain transmission issue. It has only ever been serviced by Ford dealer on regular basis since I purchased it new. No warning lights or codes of any kind. This is now not safe to drive, as it’s happening almost daily. Hopefully this is a recall soon and Ford does the right thing!.

Experienced transmission down shifting at highway speeds. Traveling at approx 75 mph in OH, when truck down shifted to 5th gear and showed warning message "drive train malfuction", message cleared on key cycle. Issue again occurred 8 days later in OH/PA return trip home. No message in cluster, but vehicle returned to normal operation after key cycle. Vehicle has operated normally for the last week. Dealer tried to pull codes, none set. Appointment made to have them look at truck, but they don't expect to find anything. Continue to drive truck, and if message in cluster reappears bring it by if possible.

Driving interstate and a wrench warning came up on dash screen. I knew that wasn’t good. Two local mechanics diagnosed as circuit a (transmission) needs replaced. Park light not illuminating and won’t even crank to start. I got it started , finally, and wrench came back on. Loud “thunk” noise when switching into reverse was advised not to drive until repaired as it is dangerous to me and others recall was issued for 10 pin and needs to recalled for 6 pin ASAP Ford is welcome. To check it out anytime as I just have it setting waiting on recall. I need a truck, please issue recall.

Truck rapidly shifted from fifth to third gear, causing the truck to jolt and lock the rear tires. This has occurred at least three times since a recall was performed on the truck’s computer several months ago. After it happened today, the truck produced the following codes: p0720 and u0102. This could be detrimental when driving at high speeds on the highway. Truck can be inspected if requested. A local Ford dealer has been informed about the issue and stated that the recall would not have caused it. No inspections have been performed due to the inconsistent occurrence of this issue.

While traveling at highway speeds, my truck will downshift from 6th gear to first gear. On occasion, the heads up display will randomly flash between different driving modes (reverse, m, neutral) as if it is resetting. This also happens at medium speeds (20-30 mph).

Vehicle transmission will instantly drop to gears 3 to 5 (limp mode from what I have researched) & wrench light comes on. Very dangerous on the interstate traveling at 70mph+, seems to happen more frequently on hotter days. You can park & turn off vehicle, then crank back up, & it is out of limp mode but transmission is sluggish. Initially it was happening once per week on avg, now it is a toss up on each drive I do whether it goes into limp mode or not.

Truck has been downshifting at low gears prior to this main incident. Usually at low speeds between the 1-3 gears. But today I was driving down the highway at approximately 65 mph in the 6th gear and without warning it seemed to electrically down shift into 1st gear. I describe it as electrically because the rpm’s dropped almost instantly for a second and seemed to reboot. Which is extremely dangerous especially on a busy highway. Not only could I cause me to crash but also others to wreck into my self and poses a incredible risk for my fellow drivers and this is the reason for my complaint. Going from the 6th gear to 1st has to be some sort of recall and or an indication of far greater problem. What is even more odd there have been no check engine lights on for any of these instances.

Have had issues with transmission for years and was checked previously and dealer said no problems. Seems like it was down shifting for no reason. No recalls. In 2024 while driving I experienced sudden loss of power and seemed like down shifting from transmission on major highway and almost came to a stop in the middle of the lane. This was frightening! this continued to happen. Took to dealer and they said I had to replace the transmission.

I bought my 2017 Ford shelby f150 (v8 5. 0l, 6r80 transmission) used from a dealership in 2022, and noticed when depressing the sport mode on the shifter, and hard acceleration, that the truck will suddenly downshift to a very dangerous gear while on the freeway. I heard the ntsa engineering analysis that is ongoing, and wanted to include my experience. Since I don't touch the sport mode on the truck, it has not happened since. Ford needs to do a recall on this very dangerous issue.

The contact owns a 2017 Ford F-150. The contact stated that while driving approximately 55-60 mph, the transmission unexpectedly downshifted to first gear, causing the rear wheels to lock up. The check engine warning light was illuminated, and the wrench symbol was displayed on the instrument panel. The vehicle went into limp mode, and the vehicle was slow to respond. The vehicle was turned off for ten minutes and then restarted. While driving approximately 25-30 mph, the failure recurred. The contact stated that dtc: p1702; indicated an intermittent failure with the transmission range sensor circuit (prndl sensor), potentially causing erratic shifting or even the vehicle entering limp mode. The local dealer was contacted, but the vehicle was not diagnosed or repaired. The manufacturer was contacted and opened a case, and referred the contact to the NHTSA hotline for assistance. The failure mileage was approximately 108,700.

Vehicle unexpectedly downshifted and service now light came on. Speed was difficult to control as the vehicle would either rapidly decelerate or accelerate. Cruise control was unable to be used. I received a speeding ticket because I was unable to consistently maintain speed. Problem returns intermittently and is usually resolved by pulling over, turning off the vehicle and turning back on.

Similar to the 10-14 f150 recall for the 6r80 transmission lead frame failure. Driving down the freeway at speeds of 50-70 in 6th gear truck has down shifted into first causing loss of control. Transmission then disengages entirely and loses power mid driving. After turning truck off and waiting, starting the truck it returns to normal. Failing speed sensor and lead frame are the cause in this transmission from Ford called the 6r80 in year models 10-19 however recalls were only ever issues for the 10-14 generation for repairs of less than 10 years of age or 150,000 miles. My truck is the generation after, a 2017 model with 146,000 miles. Truck is currently at Ford for repairs and diagnostics. In the most recent event with the truck shifting from 6th gear to 1st yesterday I was in heavy traffic and when I lost control of truck I had to "sweep" to the side of road / ditch to avoid collision with vehicles behind and beside me at speeds of 65-75. I believe the year models 15-19 should be included on the existing recall if equiped with the 6 speed automatic transmission being the fact they were built and manufactured with the same failing parts before the current recall was put in place a few months ago according to online sources. Fortunately I was safe in all 3 incidents but yesterdays close call has forced my hand in "parking" the truck until Ford can repair any malfunctioning parts. If a recall is placed after my trucks repair it would be nice to have compensation for this bill. Truck has had scheduled maintenance including transmission on or before owners manual recommendations at designated Ford dealers other than oil and brake changes which I do myself at home. Please consider the 6r80 transmission as a point of recall for all models not just earlier generations as most of these trucks may not have the mileage yet needed to have serious mechanical failure. In which some failures can have trucks towing loads than can cause serious crash events.

I have the Ford f1 50 2017 model, 10 speed transmission. I about it new. In early December 2024 well on a road trip went down shifting the transmission started jerking, feeling like it was having trouble finding the correct gear. This continues to occur with subsequent driving of my vehicle. This was dangerous because it was occurring when trying to accelerate and pass other vehicles with a safe margin. This safety factor was definitely impaired. The speed was not properly controlled and the whole vehicle was jerking strongly. Luckily there were no oncoming vehicles but if there were this could have led to a head-on collision. Hesitancy to properly accelerate is extremely dangerous. Doing some research, I see that this problem was recognized by Ford in 2018 and memos to service departments were put out. I also saw that there is a 6 state class action lawsuit regarding exactly the same issue that has been issued against Ford motor company since approximately 2018. The lawsuit shows there have been numerous memos regarding this problem known about the Ford 10 speed transmission and not just in Ford f1 50s. I tried contacting Ford motor company and they said "your VIN number was not included in any recalls so you can only complain to the NHTSA". This is a known and dangerous problem that Ford motor company should issue a recall for and be responsible for repairing since it has been known since 2018 while all warrantees were still in force. My warranty is no longer in force, but Ford knew about this during the time of my warranty. I called the dealership at the time that it first occurred and they said that they had been fixing multiple transmission problems and they did get a warning memo at the time that it occurred. However I do not see any warnings on my Ford app. I also saw that in 2002 there was another class action suit against a different Ford transmission problem that was eventually settled in approximately 2008.

When using the cruise control and going down hills, the transmission will unexpectedly downshift into one or more lower gears causing the rear wheels to chirp or actually slide on wet pavement. It only seems to happen when using the cruise control for some reason.

My f150 truck dropped out of gear (5th ) to lower gear while driving. Which is very dangerous and caused almost a potential accident. Seem the power train in transmission and sensors had issue keeping truck in gear. Seems to be an issue on previous f150s and alot of 2017 models.

Vehicle stuck in 7th gear upon starting.

The 5. 0l Ford F-150 engine experienced a p2005 :manifold runner control stuck open bank 2. This code triggers when the powertrain control module (pcm) can't control the intake manifold runner as requested . It also experienced a p2007 this code may be set due to a bad intake manifold runner solenoid or actuator with a mechanical failure within the intake manifold runner system. Symptoms included poor engine performance, reduced fuel efficiency, and engine surge. It also has a p2019 dtc code related to the intake manifold flow control valve/position sensor, also called known as a imrc valve/sensor (typically located at one end of the intake manifold) which helps the vehicle’s pcm control the amount of air being allowed into the engine at various rpms. This code is set for bank 2 errors. This is a safety issue as my vehicle slowed down and experienced significant power loss on the highway. Ford is aware of this problem with defective parts and has not issued a recall. Ford's answer is have the entire intake manifold replaced at the owners cost.

When driving on hills or moving from a stop to get into traffic the vehicle will go from 4th gear to 1st and won’t accelerate. After this happens I’m alerted with “powertrain system fault”. This causes a safety issue for me and others because on hills it won’t accelerate and it rolls backwards. From a stop trying to get into traffic it won’t move and becomes a collision waiting to happen. This problem happens very frequently but hasn’t been confirmed or inspected yet. The only warnings are “powertrain system fault” no systems and first appeared late June of 2024.

Random downshift, loss of engine power, then power comes back at high rpms then truck recovers. This has happened 3 times. Today, I was driving at approximately 55mph, with no throttle variation, the truck lost power and downshifted. Whatever gear it found it was enough to bark the tires.

Cruise control randomly disabled several times while traveling. This is a known issue with the clock spring and is a significant safety issue!.

Well the last few days in colorado its been cold and every morning when I get in my truck the guage cluster does not come on. I have a few flashing lights but nothing else works. I am not sure what all is effected by this problem. After about 10 min. Everything goes back to working as it should. But then the next day it happens agian. I have done some research and this is a problem that Ford has had in the past that they had fixed on vehicals that were built up to the month before mine.

I was driving home from work and without any warning I lost the ability to accelerate when I was on the freeway, a message popped up on my truck screen powertrain malfuction/reduce power. I was lucky this time around as I was able to cost to the shoulder cars however were speeding up to me and around me as I could not accelerate my truck. If this would have happen when I was towing my old 35 foot trailer it could have been deadly. I noticed a recall for this exact same issue on 2011 trucks, forms online seem to suggest others have had this same issue with newer 2017 trucks also. The issue turns out to be the molded lead frame failure. Once more same issue from recall title was6r80 recall number 19507. Seems like Ford did not fix it only prolong the issue or kicked it down the road. My truck is 100k others around 77k it failed so I am assuming it will happen as trucks get around 100k.

The lead frame on valve body in transmission, most Fords have this recall, truck gets stuck in gear.

There is an issue with the transmission slipping or not engaging properly. There is a strong and often loud jolt with a hard shift at times. It will also simply not engage in the next gear other times. I can be pushing down on the gas and you can hear the engine revving but the truck isn't picking up speed. This has been the most dangerous part of the transmission issues. If I'm pulling out to cross an intersection or turn onto a street and the truck isn't moving, my family is in extreme danger of being hit by oncoming traffic. The vehicle was looked at for this issue at the Ford dealership, mel hambelton, in wichita, KS previously. The issue seemed to be better, almost non-existent, after I believe they reset some code. The problem has returned in the last couple of weeks and is much worse. We have an appointment Nov. 1st to have it looked into again. I don't feel very safe driving my vehicle and we couldn't get it in for at least 3 weeks to the same dealership so we are using the Ford dealership in hutchinson, KS to hopefully get it fixed sooner. There is no warning/check engine associate with this issue.

Dtc p0707 transmssion would go into limp mode while driving in the freeway at highway speeds and drop down to 20-30 mph almost got rear ended common issue on Ford f150 with the 6r80 transmssion for the module lead frame recall but only for earlier built but this are also having issues sane transmission same concern.

F150 will not shift out of gears. Example, stays in 1st gear, regardless of speed. Ford dealer said it was a "molded leadframe" transmission problem at first, then decided to "reprogram" the computer to eliminate the shifting problem. Problem returned a few weeks later. Now shifts immediately into 7th gear (instead of 1st) and stays in that gear only. Ford dealer is not able to acquire the "molded lead frame" part to repair my vehicle. This problem was subject to an earlier year recalled which does not cover my 2017 vehicle.

While traveling down the interstate at the posted speed limit of 70 mph in the fast lane, I experienced the vehicle immediately hesitating without pressing the brake and a loud grinding noise in the front drivers side and caused me to put on my brakes, change lanes and drive off to the side of the road. The grinding stopped and then it happened again about 20 more miles down the road. I was able to get it to the Ford dealership and was told it was a defective iwe check valve which attempted to put my vehicle into 4 wheel drive. As a result, I had to replace the front iwe and the new & improved iwe check valve which was designed to prevent this from happening in the future. For obvious reasons, I became upset that a known issue with defective iwe check valves causes this event to occur. After exploring the internet for this same exact problem, I found this has been going on for more than 5 years. I now have the "corrected" part, but my major concern is that while I did not get into an accident this time, what is to prevent it from happening to someone who may not exhibit the same composure and causes their vehicle to crash into someone else and death or injury is caused and could have been prevented with a relatively cheap replacement part.

Truck downshifts periodically from 3rd to 2nd gear or from 4 to 3 of 4th to 2nd, for no reason, while keeping speed same on flat road. This causes tire squealing action in some cases and is unsafe. Also, at the same time, rear motion sensor system failure light comes on with an ok button. I select the button and then a wrench sign lights up indicating service requires. Sometimes also a check engine light comes on. Sometimes also the display showing what gear truck is in goes blank, or flutters through all gears. Sometimes a fan/generator comes on as well for no apparent reason. Sometimes the truck is goes in to no gear at all (neutral?) while I am moving. I pull over, restart the engine and the problems usually go away. This problem was reported to 2 Ford dealers (cella and bergey) on about 7/2022 and 8/2022. They gave me very different assessments of the problem, the most expensive being a new lead frame ($1,300) problems originally started around 3/2022. Truck has about 35,000 miles on it.

Digital cluster malfunction, causing speedometer and fuel gauge to both display zero, loss of power to windows, loss of parking brake function, blacked out backup camera, no heat or a/c. Highbeams stay on and cannot be switched to low beams. All happened while the vehicle was in motion on a highway at 60 mph.
