Vehicle Speed Control Problems of Ford F-150 - part 1

2019 F-150 2. 7l ecoboost, 10-speed. Intermittent unintended acceleration: while coasting or braking at low speed (10–25 mph) the engine suddenly revs to 3–4k rpm with a strong lurch forward against the brakes. Requires hard braking and shifting to neutral to stop. Happens year-round, warm or cold, no warning lights. This is a known issue covered by TSB 19-2135 and ssm 49240 this problem started in 2020 at about 10k mileage. Has occurred about 10 times since with about 82k mileage now. The service dealer at acton Ford tried to reproduce the problem a couple years ago by driving it, but acceleration problem didn’t happen. The problem occurred today, Dec 6, 2025 while braking for a stop light when I had to stomp on the brakes and shifted into park. This could be dangerous if I pulled through the red light into cross-traffic.

Ford has refused, on multiple occasions and at multiple dealerships, to address the NHTSA recall number 23v896 (mfg. Recall number 23s65) issue with the wheel end hub bolt in the rear axle. Well, this weekend, the bolt on the passenger side rear axle broke off, rendering the vehicle undriveable. I brought it in to the lithia Ford dealership (who's online information said they were open) to get it addressed. They were closed, no one was there, and they won't even give me a loaner vehicle while the F-150 is inoperable. This recall has been out for two years now and they still won't deal with it. Absolute neglect of their obligations and an unsafe practice!.

My truck started experiencing the notorious Ford "limp mode" needs lead frame replaced. Ford has a customer satisfaction program directly related to this issue but though its 20k under their 150k limit it is over 10 yrs old so they are not honoring anything or doing anything about covering and cost associated. Pretty crappy of Ford.

Driving 70 mph on highway. Transmission suddenly downshifted from 6th to 5th. Cruise control turned off. Speedometer went to 0 mph. Airbag warning light came on. Wrench indicator flashed. From this point on, transmission would only use gears 3,4,5. Speedometer continued to read 0. Cruise control remained inoperative and airbag warning light remained on. Wrench indicator turned off after a few minutes. Was able to limp home, but truck had difficulty pulling out from stoplights and stop signs due to not being able to shift below 3rd gear. After shutting off ignition and restarting. Operation returned to normal.

Transmission downshift to first gear on the highway.

I was driving along and the truck shifted out of gear. Throttled to high rpm’s and went back into gear causing me to temporarily loose control and it repeated itself 2 more times before I got it stopped and towed home.

Took vehicle to dealership to have recall 19v075 completed. Dealership informed me that Ford motor company will only replace the multi- frame part in the transmission that contains the oss sensor if the vehicle is not older than 10yrs and 150,000 miles. The service advisor at the dealership informed me that if they perform the pcm program update without the mechanical repair being done the intermittent downshift problem would get worse. The truck has downshifted while going down the highway at approximately 60mph and the abrupt downshift nearly caused me to loose control of the vehicle.

On November 2nd, 2025 at approximately 6pm, in houston, texas, my 2025 Ford f?150 with Ford bluecruise engaged in hands?free mode was traveling with traffic at about 70 mph on a major thoroughfare. Without driver input, the system rapidly reduced speed to about 50 mph after it appeared to misinterpret an unknown speed?limit change. This sudden, uncommanded deceleration created a hazardous speed differential with surrounding traffic. I swiftly took over manual control to maintain traffic flow and prevent a potential rear?end collision. No crash or injury occurred, but the behavior constitutes phantom braking and false speed?limit recognition in an advanced driver assistance system feature.

Hello, we have been experiencing downshifting and slipping of shifting with our Ford F-150 that has 80k miles on it. This has caused us to loose power on the road thus putting us in an unsafe position with other drivers. We have reached out to our local dealership where we purchased the vehicle and found that we need a new transmission. When researching this, we found that there are alot of Ford F-150 owners the same years as ours that have the same situation. We are concerned that this is not a recall. It is obviously a safety issue for drivers and others on the road.

Transmission shifted into 1st gear while doing 65 mph on the freeway. The rear tires locked up as a result and the truck spun out in front of on coming traffic putting myself and my 6 month old nephew in a life threatening situation. This is not okay. I was told the most recent recall done on this vehicle was done to not allow this to happen. This issue has been an on going problem with these trucks and Ford has still yet to rectify the problem. This can cause serious bodily harm to myself and others around these vehicles. I feel Ford needs to do something about this issue.

I was sold a 2013 Ford f150 XLT with a serious documented safety issue. The issue is a transmission molded lead frame failure. This specific component defect is classified as a known, safety-critical issue by Ford (customer satisfaction program 19n01). The car dealership that sold me this vehicle is township auto line 442 delsea drive sewell, NJ 08080. I was able to get the truck repaired, however the business that sold me the truck is unwilling to reimburse me for the repairs for the safety-critical molded lead frame repair. This is a matter of selling a vehicle with a known, active safety hazard. I can provide the Ford repair invoice upon request to verify the diagnosis and repair cost.

I have had 2 instances of my f150 downshifting at highway speeds to 2nd gear while driving. I was not towing a trailer, just driving normally in both cases on my daily commute to work. The first instance was resolved by coming to a stop, shifting to park, and shifting into drive again. The second instance, I released the accelerator completely, shifted the gear selector to neutral and back to drive while coasting and it seemed to correct. Neither have led to loss of control but it is startling and not a great thing for the longevity and safety of my vehicle. I see how it could become a problem. After instance number 1, I thought perhaps it was a fluke. I now have learned that there have been prior model years of this truck transmission that also have had issues and I am more concerned that this get resolved. I now plan to have vehicle looked at by a dealership in the near future. First incident was early September and second incident was oct. 20, 2025.

There have been multiple problems with the leadframe in the 6r80 model of transmission. I have had my speedometer go out and cause the truck to shift into 1st gear causing my wheels to lock up while im driving 60mph down the highway. Ford states on the campaign to be eligible it must be under 10 years or 150000 miles whichever comes first of the customer satisfaction program but I believe it should be considered a saftey recall. The vehicles should be eligible for this program well beyond 10 years for safety reasons. In the winter it will be even more hazardous. Myself or someone else could die due to the wheels locking up. I have researched and found many others with the same issue and this should be escalated to a proper safety recall rather than a csp.

Driving on interstate highway. Entered a tunnel at 65 mph. Near the end of the tunnel traffic started to slow down. I applied the brakes and the engine started to accelerate. I had full pressure on the brake pedal but the vehicle kept accelerating. There was a loud fan noise. Fortunately the vehicles ahead started to accelerate up to the speed limit - and beyond. I took my foot off the brake and turned on cruise control. The fan sound stopped and the truck maintained cruise control setting. I had heard the fan speed up twice before but I was parking each time1 and turned off the engine within seconds of hearing the fan motor speed up. I returned to my home and heard the fan motor speed up once more. I took the vehicle in to my local service station. They were able to recreate the problem. "bad thermostat causing engine cooling fan to come, increasing idle speed. Replaced thermostat".

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.

I was driving in the morning car was started to lag on accelerating and shifting gears slightly. My dashboard and gps system flickered on and off when this happened. The truck putted as well. On my way home the car had trouble accelerating and dropped from 5th gear all the way to first causing me to almost lose control of the vehicle. It continued hard shifting and loss all acceleration. It continued flickering everytime it would sputter and slip gears, gps and dashboard would flicker. They gears were going haywire. I could not accelerate with the pedal all the way to the floor, and was hard to turn steering wheel. Almost like the truck was coasting. When we took it to the mechanic they stated it was a transmission range switch which is an issue and many f150's of my year, make and model. My vehicle was not listed as a recalled vehicle yet has the same issue as the other recalled ones. Total repairs are going to cost around $2000. I have not driven my vehicle since the incident and I am frightened after almost losing control from the hard shifting. Prior to this the vehicle ran great. It was an out of nowhere issue. The truck has been maintained well, with all oil changes, and regular maintenece. There is less the 96,000 mile son the truck as well.

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!.

Gears dropped fast on the highway, rpm's went up because my foot was on gas because I was on the highway, rear end locked up and I skidded going from 60mph to 30 in a second.

While overtaking another vehicle on a 2-lane highway, the accelerator pedal broke and would not allow me to accelerate. Shortly after this, the vehicle I overtook had caught up, and I was forced to move back behind them in heavy traffic as there was also oncoming traffic. With no accelerator, I had to pull off to the side of the highway. Losing acceleration is a serious hazard, impacting the ability to safely control the vehicle and react to situations. This was a sudden failure with no warnings. Nobody has seen the vehicle yet. I found a way to manipulate the acceleration system/assembly in a way that would allow me to get away from the busy highways. This involved me holding part of the assembly with one hand while pushing on the pedal with the other hand. I figured it was better to find a safer place to park the vehicle. Upon further inspection, it appears that a plastic part broke somewhere. I do not think that plastic should be used in heavy use and safety critical systems. Everything is available for inspection as of now if needed.

Hard downshifts from 5 to 4. At low speeds, like parking lots it shifts hard from 1 to 2. At freeway speeds while attempting to pass instead of dropping a gear to passs it downshifts to 1st, rpm’s shoot up and it results in having to pull off stop and place in park. Once in park back to d and able to take off. At any speed from 30 mph or more there is a sort of “tap of brakes” feeling every . 15 of a mile.

Unknown awkward 10 speed shift problems.

Transmission randomly down shifts and then shifts back up a gear. Then speed control randomly drops and won’t respond.

While driving down the road, the driver gauge display screen completely goes dark. All information displayed normally on the screen, such as speed, mileage, and vital information about the vehicle stops, displaying entirely. This has happened multiple times. Usually the next day, the issue is solved. Then, several months later, the issue reappears. Whenever the vehicle is taken for repair, the dealer simply cannot replicate the issue. This is a known issue that has been reported online by many people.

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.

Vechicle shuts off during high speeds causing driver to loose control and driver and passengers to be tossed around even while constrained with seat belts.

When driving on the interstate with the normal flow of traffic at 55mph, the vehicle abruptly downshifted from 6th gear to 1st gear causing the the vehicle to lock up an nearly caused an accident. This was followed by a a mechanic warning light and the speedometer to lock out and no longer work. Once pulled over, the vehicle was powered down. When the vehicle was turned back on operation returned in a limp state.

The speed sensor in transmission isn't working properly it shift down to 1st gear as shown in these recalls 19s07,19s19,and 24s37. Im not sure if it is related to 19n01 in any way but the problem was that its showing on my VIN that they conducted a recall 19s07 on my 2012 F-150 in the past but then after that there was a 19s19 recalled added because the prior 19s07 didn't work properly or hold up ,so what that meant was they should have made it aware to all vehicles that was performed with this reprogramming recall but they did not send any notification or make available to my f150 especially knowing the reprograming didn't hold up, so I was never granted access or authorization and notified that it need to be re done . Also the problem I noticed says its with the software in 19s19 and 19s07 but this seems more like a speed sensor problem that's indicated in 24s37 and that seems to be a hardware issue ,if u look into this issue on line you'll notice the fix for this issue is for the sensor to be replaced in the transmission . I feel that Ford should be responsible for the issue with my f150 .

Vehicle information: 2014 Ford F-150 VIN [xxx] transmission: 6r80 description of the problem: my 2014 Ford F-150 has a dangerous transmission issue. It suddenly downshifts from higher gears (like 4th or 5th) into 1st gear while driving, without warning. This creates a serious risk of loss of control or rear-end collision. Ford performed the recall for the 6r80 pcm reprogramming, but the issue persists. The problem was not resolved, and the vehicle still downshifts abruptly. My vehicle has over 200,000 miles, so the extended warranty for the lead frame (program 19n01) no longer applies, but this is a serious safety defect that continues after the recall. I’m requesting that the NHTSA investigate this issue, as it seems the recall fix is not effective in all cases. Many other owners report similar symptoms even after the recall. Safety concern: I feel unsafe driving this vehicle. The transmission can cause a sudden deceleration in traffic, and I fear it may lead to an accident.

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.

Transmission shifts hard and accelerates unexpectedly. Acceleration is not smooth as expected.

While driving at highway speeds, about 55mph, transmission just jerked. Happened multiple times until I could get it in to be serviced. Service light comes on, speedometer goes to zero, safety lights come on and its not able to downshift. I fear this could be a very dangerous especially at this speeds. . After stopping and turning of the road it still would not reset. It would not reset until I parked the vehicle and shutdown then restarted. Picture attached shows the dash. . . . . While going 55 speedometer went to zero. Was in 5 gear and would not change, mileage went to "--------" engine light and airbag lights come on. . . . . . Nhtsa site shows no recalls but Ford does show their own recall. Ford will not cover this repair because they said they notified of a recall but nothing was ever sent to me or told to me in any previous trips to dealership. This is a known safety risk and Ford should still be pushing to get these parts replaced. Fords campaign after to search online. 19n01 description transmission molded leadframe.

I was driving my truck down the highway and all of a sudden my rears wheels locked up making me lose control of my truck take goodness I did'nt rollover no my transmission is shifting threw gears from 1st to 6th to 3rd this is my second f150 that I have had my old one had the same problem but my old one didnt lock up my tires my phone number is 806-500-9173 arturo rivera but please text because at work you cant use my phone my truck is parked in the garage im afraid to drive it need assistance in fixing it.

2018 Ford f150 XLT twin turbo 4wd. Since the day I bought it. Nothing but problems with lurching jerking at stops. Clunking when truck is on and off. We have video of it. Pushing gas pedal and truck hesitates before it jumps forward always the transmission been to every Ford dealer in our area they refuse to help or say they dont hear the knocking or feel lurching all lies we have had at least 3 close calls avoiding accidents and 2 days ago the truck would not stop the transmission skipped and I hit a deer. My bull bar absorbed most of the impact. The 10 speed transmission is the issue and no one wants to hear it but Ford wants $10,000 for a new transmission after I paid $48000 for this truck and it’s been in the shop half the time.

On [xxx] with an empty vehicle besides I myself the driver, going south bound on [xxx] just north of twin falls idaho I had cruise control set to 81 mph when I felt a slow to the vehicle then noticed an uncontrolled/unprompted shift and loss of power indicated on the dash cluster jumping from 10-9-7-10-5-3-8-9 gears then transmission temperature went from 176 degrees to 205 degrees for the remainder of the trip. I proceeded to pull over and let the transmission rest for 45 mins then proceeded with my trip after not seeing any exterior damage or leaks. And it did not shift higher than 9th gear while cruise control was engaged even at lower speeds. The transmission then began to experience harder shifting, and gained a shutter like a clutch pack not engaging properly form 1-3rd gear, and sporadic shifting under light normal driving conditions at random intervals and remains to now have a normal operating temp of 204 degrees under normal driving conditions. Took it to be diagnosed at a Ford dealer and it was the cdf drum that lead to a a cascade of issues leading to the transmission needing replacement.
