Vehicle Speed Control Problems of Ford F-150 - part 2

While driving in sport mode on an interstate, during descending downhill, the transmission started down shifting. At that time near the bottom of the hill was standing water on an area. It was suddenly like hitting the brakes & I hydroplaned, but luckily I never touched the brakes. The down shifting at the same time as hitting the water caused the vehicle to loose control of the road. Luckily I regained control by steering and did not wreck. There should be a safety warning on this issue or a correction in the vehicle down shifting.

On July 2, 2026, the vehicle was brought to an authorized dealer for a scheduled appointment to resolve active safety recall 26s45 / NHTSA campaign 26v378 (6r80 transmission sudden downshift defect). The dealership refused to perform the recall software update, claiming it was not needed for the vehicle. On July 12, 2026, while traveling at highway speeds on a public highway, the transmission suffered the exact un-commanded sudden downshift described in the recall. The violent mechanical force instantly snapped the rear driveshaft in half and severed the undercarriage air conditioning lines, creating a sudden, life-threatening loss of control and wheel speed reduction on a live highway. The vehicle is now permanently disabled due to the dealer's refusal to fulfill a federal safety mandate.

I'm not sure what failed but a google search with symptoms tells me it's a "throttle-by-wire" malfunction. The f150 truck accelerates immediately and aggresively to full throttle when I floor the gas peddle to merge traffic on freeways. It continues at full throttle regardless what I do. Braking gives a pop up window on the dash that reads "brake applied power reduced", and the brakes do slow the vehicle and even stop it but the engine revs at full throttle. This occurred the day I bought it driving home from dealership, testing it, I floored the gas peddle while on the freeway to see how it performs accelerating while passing other vehicles. It took over that day, I thought it had somehow activated cruise control being a new vehicle and me unfamiliar with operations, I would figure that out later and forgot. I pulled over that day, killed engine, restarted and it was fine. It repeated this malfunction two maybe three other times since that first day. Yesterday, xxx, would be the third or fouth time it has occurred and it wouldn't correct. I pulled over three times, put it in park and it reved full throttle, killed it, waited two minutes, restarted and it went to full throttle. It is parked in my driveway and will accelerate to full throttel immediately even in park. I am going to have it towed this morning, xxx to brinson Ford in [xxx]. Therefore, a dealer has yet to look at it or try and reproduce problem. The first occurrence was the day I bought it which was September 12, 2025.

Component; likely the transmission safety revs went to almost zero on highway. Transmission seemed to stop the truck. Then intermittent on and off transmission. Seriously struggled to get the truck off the highway momentarily no ability to control speed: then on and off with the acceleration. Very scary! sudden drop in speed on the highway could have caused an accident with no brake lights on problem been reproduced: not to my knowledge. Its at a dealer now. Not safe to drive been inspected: at dealer now prior warning - lamps etc: none whatsoever oil lamp came on, then the check engine light came on well after the initial scare.

Made a complete stop and vehicle accelerated at a high rate of speed and could not stop.

Ford corporate case number: cxh-09262770. My 2015 Ford F-150 has experienced sudden, dangerous transmission downshifts at highway speeds that nearly caused a fatal collision. I complied with Ford's mandatory recall 26s28 software flash, but the dangerous hardware symptoms remain active. The vehicle is currently grounded and unsafe to drive at the dealership lot, but Ford corporate is denying the physical lead frame replacement due to narrow diagnostic code restrictions. ".

On Thursday, xxx, at approximately 5:10 am, I was driving my Ford F-150 XLT (VIN: [xxx]) eastbound on [xxx]. While exiting the elevated bridge at the intersection of [xxx] and [xxx] at 55 mph (6th gear), the vehicle experienced a sudden, uncommanded transmission downshift directly from 6th to 1st gear. This caused immediate extreme deceleration, engine over-speed, and locked the rear tires, causing tire slippage and an absolute loss of traction control on a high-speed highway. This severe event put my life and my wife's life in imminent danger of catastrophic injury. After safely pulling over, the malfunction indicator light (check engine) and the powertrain fault warning light (wrench icon) illuminated. The electronic cluster froze and failed to display the gear position. Drive (d) mode was completely unresponsive. I managed to vacate the active roadway using manual (m) mode. While driving in 4th gear in manual mode under extreme caution, a second violent, unintended downshift to 1st gear unexpectedly occurred, confirming the persistent, dangerous nature of this failure. Consequential mechanical damage includes severe transmission clunking noises during gear engagement and a constant internal metallic knocking sound from the engine block caused by the forced over-speed. This failure perfectly matches the technical failure mode described in NHTSA safety recall campaign 26v237 (oss to pcm signal loss). On xxx, at 11:10 am, I personally visited arceneaux Ford inc. (authorized dealership in [xxx]) to report this safety defect, open a service case, and request a safe vehicle inspection and loaner. The dealership explicitly refused to open a case or take action, stating that "Ford motor company does not currently have an engineered solution for this problem," leaving me stranded with an unroadworthy, highly hazardous vehicle. Information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

While driving at 40-45mph, the vehicle abruptly slowed to 15-20 mph, with no warning whatsoever. I narrowly avoided being rear ended by a box truck by moving into the turning lane. Had I been on the highway, this would have led to a catastrophic accident. I am concerned for the safety of my family, myself, and other drivers. Please reinstate/ extend the statute of limitations, or make exception for recall campaign 19n01, for this safety issue, as the Ford dealership I contacted about this issue declined to correct this safety issue under recall terms. Thank you for keeping roads in this united states as safe as possible!.

Hello, I recently brought my 2014 Ford F-150 (VIN: [xxx]) to the dealership regarding recall 24s37. The vehicle experienced the following symptoms: • check engine light illuminated. • wrench light illuminated. • intermittent loss of power. • abnormal transmission behavior. • intermittent no-start condition. • vehicle would only start after moving the gear selector. The dealership informed me that no physical repairs would be performed because the diagnostic trouble codes retrieved were different from those associated with recall 24s37. However, the vehicle continues to exhibit transmission-related symptoms, and I am concerned that the underlying condition may be related to or aggravated by the conditions addressed in recall 24s37. I am requesting that Ford review this case and determine whether additional diagnostic evaluation or repairs should be considered. However, they refuse to accept that the codes have anything to do with the recall, even though it is the same part and the affected sensor that is triggering the error codes on the scanner. They are asking me to pay for the transmission repair because the codes are not the ones approved for the recall, but based on the signs and symptoms the truck is showing, it is a chain reaction that triggered the previously mentioned failures. Thank you information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

The contact owned a 2015 Ford F-150. The contact stated that while driving at an undisclosed speed, the vehicle lost motive power while approaching a stop. The contact depressed the brake pedal; however, the vehicle unintendedly accelerated and crashed into a Chevrolet tahoe. The wrench symbol warning light was illuminated. There were no reported injuries. The air bags deployed as intended. A police report was filed. The vehicle was towed to a tow lot. The insurance company towed the vehicle to the total loss yard, where the vehicle was deemed a total loss. The local dealer was not contacted. The vehicle was not diagnosed or repaired. The manufacturer was not notified of the failure. The approximate failure mileage was 310,000. The VIN was not available.

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.

The speedometer on my vehicle recently indicated a speed 10-15 mph lower than the actual highway speed. Approximately one week later, while operating the vehicle with cruise control set at 58 mph and descending a decline, the transmission unexpectedly downshifted from sixth to first gear. This abrupt shift resulted in a violent jolt to the rear of the vehicle, nearly causing a loss of control. Upon contacting Ford regarding this issue, I was informed that they are aware of the problem and that an extended warranty campaign is in place for the transmission lead wire frame and vehicle speed sensor. Ford offered to repair this free of charge, with the caveat that the campaign covers vehicles up to 150,000 miles, originating from 36,000 miles. According to various owner groups and online forums, this issue is prevalent in 2013 F-150 pickups equipped with a 6-speed automatic transmission, often manifesting well after the 150,000-mile mark, as was the case with my vehicle. While Ford acknowledges this known problem and its potential consequences, the warranty repair cutoff at 150,000 miles could lead to catastrophic outcomes, as demonstrated by my near-loss of control incident. It is important to note that the same transmission and speed sensors have already been recalled in 2014 models, which share an essentially identical powertrain, yet the 2013 models are not included in this recall. This presents a significant safety concern, as the manufacturer is aware of the issue, but their current campaign does not adequately cover the mileage at which many of these problems are emerging.

The truck has sporadically gone into “limp” mode for 6+ years. In the last 4 weeks it has happened a total of 6 times while driving. On Tuesday 6/9/2026 it happened while leaving a driveway. I was able to disconnect the battery and let the throttle body reset. I reconnected the battery, it started and drove without problems. I connected a loaded horse trailer, drove approximately 12 miles and it happened again, this time on a two lane road with a soft , uneven shoulder going from 60 miles per hour to 8 miles per hour very quickly. I was able to turn on my hazard lights and pull onto the grass, but only about 5 inches off the 60 mph road. In order to reset the throttle body, I disconnected the battery again, disabling the hazard lights while vehicles passed by narrowly colliding with us several times. The check engine light was illuminated, but I was not in a safe place to scan the truck. It usually disappears after resetting the throttle body, but did not this time. After 10 minutes, I heard the throttle body click, it started up and I drove another 15 miles when it happened again. This time at a temporary stoplight with no shoulder. I was able to scan the computer and the p2111 code was displayed. I reset the throttle body again, drove 5 miles and it happened again. I was able to navigate to a safer area, reset the throttle body again and drive less than two miles home. On 6/11, after letting the truck sit for two days, I started it with no issue to move the trailer and it happened again. I tried resetting the throttle body again and if did not work. The p2111 code is still showing and the throttle body will not reset. The truck is currently inoperable. It will only idle, roughly, and pressing the accelerator pedal had no effect on the truck.

My local Ford dealer (tallahassee Ford) which I had just purchased the vehicle from two weeks prior. Refused to repair NHTSA recall number26v237 they wanted to charge me over 2000 dollars to fix even though it has a recall. I ended up getting the lead frame replaced at a local transmission shop for little over 1000 dollars. I would like to be reimbursed for the money and time I spent.

I am having a lead frame issue. At various speeds, the vehicle will just down shift, locking the tires and causing a hazard for other drivers which could be a very dangerous situation. I was impacted from the rear due to this occurrence. It causes extreme jerkiness when doing this which is also injurious to my back and neck and shoulders.

The truck exhibited the abrupt downshifting upon driving out of the parking lot, this caused great stress and possible accidents to me and family. The transmission continued to get worse and we were in fear of our lives to drive the vehicle on the highway. Once we got the vehicle home it literally would not shift into gear and has been disabled since the first week in xxx. We are plumbing and heat contractors and have lost a great deal of business due to not having a truck/this truck to use for work. We had it towed to greico Ford in [xxx] on advice from keith, the service mgr. We know the recall is due in xxx. This dealership is now trying to tell us that all the hoses are damaged and wants to charge us $2,000 to repair the hoses. We obviously don't want to do this since we believe the violent jarring and downshifting of the transmission caused by this mfg defect probably caused this and a lot more other problems. Mfg recall #26s28, NHTSA recall# 26v237. I need to know when this recall remedy will be submitted and what are my rights to get this fixed? information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

My 2019 F-150 has only 25,000 miles. The dealership has confirmed transmission failure requiring a $9,000 replacement. A transmission is expected to last significantly longer than 25,000 miles. I have maintained the vehicle. This is an extraordinary premature failure on a critical part of the vehicle and it poses a massive safety liability.

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.

My 2016 Ford F-150 is currently subject to recall 26s28 / NHTSA recall 26v237. Prior to the recall remedy becoming available, the vehicle began experiencing erratic transmission shifting and illuminated the check engine light, wrench symbol, and codes p0720 and p0722 were present. I brought the vehicle to an authorized Ford dealership for diagnosis. The dealership documented that the vehicle was experiencing erratic shifting and was considered not drivable. The technician determined that the erratic shifting condition was related to dtcs p0720 and p0722 and recommended replacement of the transmission lead frame/conductor plate. The technician also noted the need for additional diagnostics involving the output speed sensor (oss) circuit within the transmission. The vehicle remains available for inspection at the dealership. This condition created a safety concern because the transmission was shifting erratically and the vehicle could not be relied upon for normal operation. Unpredictable transmission behavior creates a risk during acceleration, merging, highway travel, and other driving situations where consistent vehicle response is required. At the time, I was preparing for a cross-country military pcs move and did not believe the vehicle was safe or reliable to drive long distance. The problem was confirmed by an authorized Ford dealership who documented the condition, diagnostic codes, and repair recommendation. The findings were provided to Ford motor company through corporate case number cxh-08096574-l9m6t4. Ford representatives advised that the automotive safety office was notified regarding the technician findings and the open recall. My concern is that the vehicle developed transmission-related symptoms involving p0720, p0722, erratic shifting, and a recommended lead frame/conductor plate replacement while subject to an active safety recall affecting related transmission systems. Ford has stated that the recall remedy is not available until July 2026.

Contacted Ford about recalls 26s28 and 19v075 and they report that my vehicle is out of the warranty period for repair. They were advised that this is under a NHTSA recall and still refuse to honor the NHTSA safety recall stating that it is outside the window for replacement. Again advised them that this is a NHTSA recall and they still refuse to honor it. My vehicle is inoperable due to this.

Driving down a two lane road without any cruise control on the truck suddenly speeds up to almost 90mph with out pressing on throttle had hold brake down engine rpms were in the red shut truck off for it to finally go back to normal.

2016 Ford F-150 experiencing intermittent and dangerous transmission behavior consistent with the current Ford safety recall involving unexpected transmission downshifts on vehicles equipped with the 6r80 transmission. Vehicle previously required a full transmission replacement/rebuild in September 2025 after repeated violent downshifting and drivability problems. Diagnostic codes at that time included p0705, p0707, p1702, and p1921 involving transmission range sensor and intermittent transmission signal faults. Following the rebuild, intermittent drivability concerns continued. Over several months, vehicle would periodically not “sound right” during operation, although symptoms were difficult to duplicate consistently. Check engine light would intermittently illuminate after approximately one hour or more of continuous driving and later clear itself after vehicle cooled down overnight. Current symptoms have worsened and include unexpected downshifting, inability to manually shift using dash controls, skipped gears, delayed downshifts/upshifts, remaining in 3rd gear while slowing to a stop, and behavior consistent with being stuck in low gear while traveling above 50 mph with excessively high rpms. Vehicle intermittently appears unable to properly determine gear position. On may 19, 2026 I experienced uncontrollable downshifting and engine revving that resulted in an inability to safely operate the vehicle. Transmission behavior creates unsafe driving conditions and concern for loss of vehicle control during highway operation. Vehicle is now considered unsafe to operate and will be towed to a Ford dealership for evaluation related to the active safety recall.

See attached document for complaint.

About 30 mins prior to the incident,the accelaration was vey slow getting upto only 30/35mph message appeared in dash board instructing to schedule maitanance service soon. My last service was done only 2 months ago. Anyhow I decided to drive the nearest Ford dealer. On exiting the freeway,the ramp was downhill and the braking system completely failed and I crashed into the pavement. All the airbags came on. I have sternal contusion.

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.

1. Unexpected downshift into second gear while driving - like the engine is falling - causes severe jerk and sometimes truck revs/ goes into neutral - just revs. 2. Frozen tailgate latches and door latch defects 3. Additionally the transmission harsh shifting when cold (safety/drivability defect): when the vehicle is cold, the 10?speed transmission shifts harshly, hesitates, clunks, and delays engagement. This matches Ford’s transmission tsbs for calibration and adaptive learning issues. The dealership acknowledged the shifting issue but did not perform the required calibration or TSB procedures. The dealership refuses to document my reported symptoms or perform the TSB repairs unless the failure is happening in front of them. This prevents known defects from being repaired and leaves the vehicle in an unsafe condition. Ford customer service confirmed the shifting issue exists but the dealership still did not perform the calibration. Ford corp customer service didnt understand and manager didn’t even know what a TSB is:/ so no help at corporate. As chuck the manager stated he didn’t know what document I was referring to and I told him the number as well ? I contacted Ford customer service and a case was opened. A customer service manager named chuck returned my call. He stated that the TSB is “not a warranty” and that the dealership “has to duplicate the condition” before Ford will authorize the repair. I explained that the tailgate freezing issue cannot be duplicated on demand because it only occurs in cold overnight temperatures, not during daytime service hours. Despite this, Ford insisted the dealer must reproduce the failure, even though Ford’s own tsbs describe this exact cold?weather condition.

My vehicle has abrupt unintended downshifts straight down to first gear at fast speeds, which is causing rear-wheel lockage near heart attack and near-loss of control spinout. The sudden downshifting causes a loud violent high extreme rpm engine over rev. Sounding as if it is about to blow up or an internal explosion. This is occurring at highway speeds up to 70 mph. At these speeds, is an immediate risk to me and others! causing a fatal high-speed rollover or a multi-vehicle collision due to this malfunction! this was a recall 19s07 for my year of truck but my VIN was somehow was not on the list which I guess makes me not qualified unless I get into a crash and then have a lawsuit.

My 2014 Ford F-150 is exhibiting symptoms consistent with the Ford transmission molded lead frame safety recall 24s37. While driving approximately 55 mph late at night on a five-lane roadway, the vehicle suddenly and violently jerked, downshifted and came to a complete stop becoming stalled out as I was approaching a major traffic intersection. The truck was disabled in traffic and would not restart for approximately 2-3 minutes, leaving me stranded in an active travel lane and at risk of being struck from behind by another vehicle at high speed. The vehicle has displayed transmission-related symptoms including inability to correctly indicate gear position, harsh shifting, unexpected downshifts into 1st gear while driving, transmission fault warnings, and check engine lights. Initially it was mostly dying while idling and we thought it was the common "fuse 27" issue, being unaware of the recall. Then the condition reproduced multiple times and symptoms worsened dramatically. Ford dealership inspected the vehicle. According to the technician's written report, the truck was found to be "having transmission problems, unable see what gear the truck is in and shifts to 1st gear while driving" and recommended replacement of the molded lead frame. The dealership confirmed transmission-related diagnostic trouble codes were present and documented symptoms consistent with lead frame failure. Despite the recommendation of the lead frame replacement and documenting symptoms consistent with the safety recall, the repair was not approved. The vehicle continues to experience symptoms associated with the recalled defect and is unsafe to drive away. Dealership confirms software update will not correct problem. I am submitting this complaint as the transmission defect poses a significant safety hazard to me, my children, and other drivers due to unexpected downshifts, loss of power, stalling, and the risk of becoming disabled in traffic. The truck remains available to inspect.

Our 2012 Ford F-150 truck had no issues and no dashboard lights when it randomly downshifted while driving and almost caused an accident. On sat, may 9, 2026, my husband pulled onto the road and got up to 40 mph when the speedometer stopped working and the truck randomly downshifted. The car behind us had to swerve to avoid a collision. On mon, may 11, 2026 we called the Ford garage they told us the customer service program (#19n01) is no longer valid as it is over 10 years now. The truck only has 128,000 miles and we were never notified of a csp when we purchased it in 2020. The Ford customer service representative said the csp was issued in 2019 but we purchased the vehicle in 2020 and were never notified of an issue. I now have a $1,500 repair bill for the leadframe that Ford will not reimburse us for and also see that they still have numerous transmission and speed control issues with their vehicles. I opened a case with Ford on may 14, 2026 [xxx] ) but their representative iomar was not helpful. Information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

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.

2 times now my truck went from 75mph in 10 th gear to 1 st gear on the highway. I then loose all throttle input. This is my day driver and some how avoided a fatal crash 2 times. I do not have a Ford dealer in my town I usually fix everything on my own. I know they have a recall and it's just a software patch. If so can you push it over the air to fix? or have a dealer swap out trucks and get it fixed. The trany had been shifting very poorly. I did a filter and oil change on it and was much needed. I also reset the tcm logic and that seamed to help but now I am scared to let anyone drive it.

I have had the 24s37 recall applied to my truck it was a software update, after the update it was ok for about a month then the problem became worse than it was before the software update. My truck is now downshifting and locking up the rear wheels and dose not shift sometimes and skips gears. This problem is getting worse everyday. I talked to the Ford dealership by my house and they told me I needed to buy a new transmission from them and there was no remedy for my problem other than the new transmission. I noticed the are recalling the 2015 trucks with the same transmission problem. Will my truck be added to the recall ? I have the same transmission.

My transmission will townshift suddenly on the highway. The error code I get is the (p0720) output-speed-sensor. I have noticed it has been recalled before. It is very scary when I am driving, and I know it has to be hurting my engine and transmission. I got a recall notice and thought it was for this, but it was for other error codes similar to this. According to my research they all seem to very closely associated. I took it to the dealership, and they said Ford won't cover my issue.

I contacted Ford about my molded lead frame because my truck has a issue with the transmission and they denied my coverage to repair the problem and it’s is expired so the won’t fix the issue.
