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

I purchased a 2017 Ford F-150 on July 9th. It is covered under safety recall 26s28 (NHTSA campaign 26v23700). On July 25th, the vehicle entered highway limp mode due to an output speed sensor failure (code p0722). A Ford dealership performed the 26s28 software flash but left the failing physical lead frame hardware in the vehicle. On August 15th, the truck reverted to a dangerous limp mode on the highway due to the same unaddressed p0722 hardware failure. Ford corporate is refusing to authorize the physical hardware replacement under the safety recall framework, leaving the vehicle fundamentally unsafe to drive.

Pcm not communicating with throttle body causes wrench light to come on and we loose control of the gas and slows the car abruptly.

Ford motor company put out a recall on the pcm. I had the recall performed and it has caused more damage to my truck. It now has eratic shifting, stuck gears, and going into limpmode. Ford forums show that this is an ongoing issue after the reset is performed creating an unsafe vehicle to drive. The check engine light is now on and was not prior to this recall reset.

My truck has shown wrench on dash multiple times, dropped gear several times suddenly. Less than 10 years old but over 150,000 miles so Ford has agreed to a fix under extended warranty program 26n04. Unfortunately they were allowed to add the phrase whichever comes first. This eliminates me from getting them to fix the cause which is the lead frame module. A pcm will not fix a bad part. This is a dangerous safety issue that should be fixed by Ford. Please save lives and get them to replace all lead frame modules if code finds it bad. It could affect anyone’s family member if an accident results.

While driving the car immediately downshifted and I could not accelerate. The hill assist came on and service advance trac came on. This happened 3 times. The first time we towed it to the dealership April 17th, and they changed the oil and tested the battery secured wires and verified after the repair on April 26th. After we picked the truck up on April 26th it stalled on the highway on the home and we had it towed again. They kept it for 4 days drove it 80 miles and said nothing was wrong no repair was done or needed. On may 13 it stalled again in front of train tracks. Luckly I was able to stop and start it quickly to drive it to a near dealership. We picked up the truck today, and it stalled again on the way home. We drove it back to the dealership today, may 23rd, hopefully they can figure it out. We are again without a car for a long period of time. We have paid $1,964. 10 in repairs that have not fixed the problem. The way the truck stops so suddenly is very dangerous as it happened once getting on the highway and once in front of a train track.

Hard downshift caused my truck to slow suddenly and became very hesitant where the vehicle behind me had to slam on their brakes. I then pulled over when it was safe, turned the truck off and then attempted to turn back on with no success due to the shift indicator no longer lighting up. This matches up with the current recall for this particular vehicle.

Took my 2017 Ford F-150 in for a diagnostic on may 8 2026 for wrench symbol check engine light and issues down shifting and sliding tires shop manager and technician claimed the vehicle is unsafe to drive and talked to the service manager deemed the vehicle unsafe to drive wanted it grounded do to the safety concerns related to recall 26s28 (pcm/trs) stated the down shifting is cause catastrophic failure to all mechanical components transmission engine and rear end kidding the tires especially in wet weather the truck would cause a accident. . Cause the sliding of the tires. . So my truck is at apple Ford of lynchburg grounded as of may 9 2026 I still owe on the truck and have no ride dealer nor manufacture was willing to pay for a rental that cost $65 a day wanted me to pay then reimburse me once a remedy was available I cant afford that. . 1600 a month we are roughly 2 months away from hopefully a remedy being available stated by recall website. . So if my truck is showing all the signs of the described in the recall(26s28) has stated in it why is Ford not putting a do not drive on the recall for all these trucks if the technician seems them unsafe. . I shouldn't have to pay for a rental I cant afford cause Ford is lacking a remedy and wont even buy it back cause of safety issues codes po732 inccorect 2nd gear ratio.

Vehicle safety hazard & recall remedy denial recall: 26s28 / NHTSA campaign 26v237 summary of issue: I am experiencing active, unsafe vehicle symptoms directly tied to recall 26s28, including intermittent transmission signal loss, warning lights, and abrupt downshifts while driving. I initially contacted Ford in April/may 2026 immediately following the recall notice, but was informed no remedy or repair parts were available at that time, forcing me to operate a vehicle with a known driveability and safety hazard for three months. Now that the vehicle is at the dealership, Ford is refusing to perform the physical lead frame replacement under the recall/field action solely because the vehicle has not latched a permanent diagnostic trouble code (dtc), despite the technician confirming physical hardware failure. Safety impact & systemic failure: 1. Defect root cause: the lead frame degradation is the primary root physical defect of recall 26s28, not secondary damage. 2. Unreasonable safety risk: forcing drivers to operate vehicles experiencing active downshifting and loss of drive power until a specific dtc latches poses an immediate highway crash hazard. 3. Inadequate remedy program: Ford’s requirement for a specific stored dtc creates an unreasonable barrier to recall execution, denying necessary hardware repairs to vehicles experiencing the exact safety failure described in the recall. Ford must be held accountable for providing a functional physical remedy for vehicles exhibiting active recall symptoms, regardless of whether a transient electrical fault registered a permanent dtc code.

I was on the freeway in eastern colorado going 75mph which is the speed limit. Luckily nobody was behind me. My truck went from 6th gear to 1st out of nowhere and I didn't know what to do, very fast deceleration and I almost lost control. I was able to manually shift with the buttons on the gear shifter back up to 6th gear. Recently on the freeway it's been acting awkward and not shifting out of 4th gear.

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.

6r80- unexpected downshifting at highway speeds without driver input causing the vehicle to slow down. Harsh/rough when shifting and sounds like I'm driving on the rudders on the side of the highway. No warning lamps or messages. Occasionally downshifts hard when I'm slowing down and then potentially locking up my rear wheels.

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.

I bought my f150 a year ago. Now I’m experiencing timing issues, vvt solenoid failure (all four) . Loss of power, limp mode, failure to shift etc … I’ve had several mechanics look at it .

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.

To the office of defects investigation:I am writing to formally report a critical data reporting error on NHTSA. Gov involving a 2017 Ford F-150 (VIN: [xxx]). This vehicle is covered under NHTSA campaign 26v370000 (Ford recall 26s28) for the transmission downshift defect. I hold the physical manufacturer recall notification letter sent by Ford motor company confirming my truck's inclusion. The vehicle experienced the exact unexpected downshifting failure described in the campaign, resulting in a collision in [xxx]. However, when searching my VIN on both the Ford portal and the official NHTSA. Gov VIN lookup tool, the database now erroneously reflects "0 open recalls. "I request that the office of defects investigation audit Ford's compliance reporting for this specific VIN. The manufacturer's database is generating false completion data, masking an active safety risk, and misrepresenting historical defect data to the public. I am having a hard time uploading my documents I will send via email. Information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

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.
