36 Power Train problem of the 2016 Ford F-150

Failure Date: 09/18/2026

There is currently a recall on 4 of the sensors on the same rail n the transmission due to it locking in 3rd or 5th gear. When I took the truck in they pulled the codes and it was not one of the 4 so Ford does not have an active recall. There was another person in line in front of me who had the same issue on the same two codes.

37 Power Train problem of the 2015 Ford F-150

Failure Date: 09/18/2026

Just over a month ago, I had my local dealership's mobile service come to perform the covered warranty reset on the powertrain module. Last week, while driving apx 40mph, vehicle went into what I now know was "limp mode" 3 times within a few minute span -- felt like vehicle shifted into neutral, wrench light came on, but did not stay on for more than a few seconds. Had a diagnostic appointment yesterday, and was informed that the molded leadframe and oss sensor need replaced, at a cost of over $1600, including the $233 I paid for diagnostics. Today I found my letter from July regarding customer satisfaction program 26n04. Everything in the letter matches my vehicle's issues, but I am being told by Ford that because my vehicle is not displaying the "correct" code per the service bulletin, it is not eligible for free warranty repair. How is it not eligible? this is a confirmed problem with the entire part, but they don't want to fork over the money to repair a cheaply made component, so they are offering bandage fixes, and paring down the eligibility criteria so narrowly that nobody qualifies to have the problem addressed. This seems predatory and negligent.

40 Power Train problem of the 2016 Ford F-150

Failure Date: 09/16/2026

Driving down highway 6/34. Cruise set at 65 mph. The truck on its own shifted into 2nd gear and revving up the engine caused the vehicle to slow uncontrollably, which is very unsafe driving. The 2016 has a safety recall to prevent this from happening. I am writing this to report that my truck has had the recall done, and this still happened. I will park the truck until Ford can fix it. But they are trying to get out of fixing this safety issue with all these trucks. At 65 mph, I lost control of the truck, and thank goodness there were no other vehicles on the road around me.

42 Power Train problem of the 2011 Ford F-150

Failure Date: 09/16/2026

I bought this truck used about one year ago. Since then I have not had much time to use it. In the last three months I have had some time to drive it. Three times in those months this issue has occurred. Luckily they all occurred on my property and no damage happened except to the truck. First time it happened an exterior mirror was knocked off, a running board was bent, scratches and dings to the to the paint, and a tailight was damaged. This all happened in reverse due to a gate opening I was going through. The motor all of a sudden had a massive spike in rpms and a violent lunge and slide of the vehicle. I learned later that it was due to a flawed part in the transmission called a molded lead frame. Transmission is Fords 6r80 6-speed automatic. Last time it happened was on 09/16/2026. It has not been inspected by any entity because apparenty I live too far in the "boonies" for anyone to come this far but the vehicle is available for inspection upon request.

43 Power Train problem of the 2016 Ford F-150

Failure Date: 09/15/2026

Powertrain recall stated because the code didn’t show on a safety recall that can cause vehicle to shift from 5th to 1st gear while driving per stated recall Ford will not honor because it’s not one of the codes they state but the recall doesn’t specify a code. We had it at the dealership twice and they said they would fix it for $ 1400. 00 well we didn’t cause the recall and we should not be responsible for paying. Would just like someone to contact us before my husband or someone else gets hurt in an accident.

47 Power Train problem of the 2018 Ford F-150

Failure Date: 09/14/2026

Driving highway i70 over vail pass, vehicle downshifted on it's own nearly causing someone to rear-end my vehicle. Took it to three local automotive business's for a diagnostic service; they all reported the same issue pp07f7-00 cdf drum and the 10th-gear not engaging. This should not be occurring when I've maintained service of my vehicle. I've paid for one diagnostic and shouldn't have to pay for one at my Ford dealer where it was purchased by I will have to again. I know of several owners with the exact same issue and no one is supporting them for this. I've owned four Ford trucks and this is unacceptable. Ford case# cxh-09395547-r9d3s2.

48 Power Train problem of the 2023 Ford F-150

Failure Date: 09/11/2026

I am reporting a safety-related transmission problem I experienced with my 2023 Ford F-150 equipped with the 10r80 automatic transmission. While driving normally, the transmission suddenly shifts violently, lurches from p to d, delayed shifting. This occurred while while driving under normal conditions creating a potentially dangerous situation because the truck did not respond as expected when I needed predictable acceleration or propulsion. I believe this incident may be related to the known 10r80 cdf clutch-cylinder/sleeve problem. Ford technical information identifies axial movement of the cdf sleeve that can cause hydraulic-circuit leaks and harsh or delayed engagement and shifting. This condition can result in slipping, rpm flares, delayed engagement, unexpected gear changes, harsh downshifts, lurching, or loss of propulsion. This is a safety concern, not merely a transmission quality or reliability issue. Unexpected loss of propulsion or unpredictable shifting while merging, accelerating into traffic, crossing an intersection, turning, or traveling at highway speed can create a collision hazard. Because I personally experienced this unexpected transmission event, I request that NHTSA investigate the 10r80 cdf clutch-cylinder/sleeve condition in Ford F-150s. Please review Ford warranty claims, dealer repair records, transmission replacements, consumer complaints, and field-failure data to determine whether this is a safety defect requiring a recall. I believe owners should not have to wait for a potentially dangerous transmission failure before this known condition is addressed.

51 Power Train problem of the 2020 Ford F-150

Failure Date: 09/09/2026

Transmission slips gears and sometimes shifts violently. I took the truck to a Ford dealership for an assessment and was told I need to replace the whole transmission. I also have a problem with oil consumption from the engine. I was told by the same dealership that this was a known problem with the 5. 0 engines built from 2019 to, I believe 2023 and that it would require an engine replacement. I bought this truck from an individual and now I am stuck with it.

52 Power Train problem of the 2015 Ford F-150

Failure Date: 09/09/2026

While driving on the [xxx], close to [xxx], throttle response was lost on the vehicle. Immediately put the hazards on, turned them off momentarily to indicate a turn off to the shoulder, traffic was right behind me, with some fast movers. “hill start assist not available” was displayed on the main panel and “trac off”/ traction control. Below approx 10 mph the vehicle started shaking violently and we came to a stop. Turned the vehicle off and started looking in the manual and online for associated issues. Was able to restart the vehicle with no annunciated issues and continued driving at a cautious speed. A few minutes later the same issue arose. Had to pull over and reset the vehicle. By this time we had committed to taking the vehicle to the Ford service center on the interstate and made it there after occurring 4-5 more times where we had to pull over during the worst time of day, avoiding traffic on the on/off ramps. We had to use heavy braking once as we were disabled and there was another disabled vehicle also pulled over and we had to stop before them with enough safety clearance. We made it to Ford. According to sb 16b32b, our truck qualifies for an expired recall based on the [xxx] plant and the production date. Ford produced p2112 code for throttle body issues. We paid for the repairs. Requesting a re-inquiry of sb 16b32b. Information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

53 Power Train problem of the 2018 Ford F-150

Failure Date: 09/08/2026

The 10 speed transmission does not shift smoothly and will periodically shift hard when downshifting from 4 to 3 and 3 to 2. Ford is aware of bushing walking which they addressed in 2022. I am one year out of my warranty which Ford would not address when under warranty but issue was less of an issue. Now that it is routinely shifting rough, they will not stand behind their transmission they knew was problematic. I have on numerous occasions been almost rear ended because they hard shift mimics a hard braking without warning.

54 Power Train problem of the 2015 Ford F-150

Failure Date: 09/08/2026

The contact owns a 2015 Ford F-150. The contact received NHTSA campaign number: 26v237000 (power train). Ford campbell sent a technician to the residence on August 9, 2026, to perform the update. While driving, the power train warning light was displayed. The technician arrived at the residence again to repair the vehicle. There was lag while driving, and the transmission unexpectedly downshifted. While driving 25 mph, the power train warning light was displayed. The vehicle was taken to another local dealer, ted russell Ford kingston pike (8551 kingston pike knoxville, TN 37919); and the vehicle was towed to be diagnosed. The contact was informed that the software needed to be updated on several occasions. The contact was informed that the fuel pump, electrical system, and battery needed to be repaired. The dealer determined that the power control module needed to be replaced. The contact stated that installing and removing the software had caused the failure, and the technician was unable to repair the vehicle. The manufacturer was contacted by phone. The failure mileage was approximately 122,984.

55 Power Train problem of the 2016 Ford F-150

Failure Date: 09/08/2026

The contact owns a 2016 Ford F-150. The contact stated that while driving 70 mph, the transmission unexpectedly downshifted to 3rd gear. The contact received notification of NHTSA campaign number: 26v237000 (power train); however, the dealer and manufacturer stated that the VIN was not included in the recall, and the fault code listed in the recall was not retrieved from the vehicle. The contact stated that after the vehicle skidded on the roadway after the unexpected downshift, there was an orange wrench light illuminated on the instrument panel. The manufacturer was notified of the failure. The vehicle was not repaired.

56 Power Train problem of the 2017 Ford F-150

Failure Date: 09/08/2026

My 2017 Ford F-150 v8 with the 6-speed automatic transmission has been experiencing a serious and recurring transmission malfunction. The truck has consistently, almost on a daily basis, gone into limp mode and become stuck in 5th gear. It also frequently fails to downshift to 1st gear when coming to a stop. Instead, it remains in 3rd gear, requiring the truck to pull away from a complete stop in 3rd gear. The dealership did perform the software update on 08/20/2026 ,yet the issues remain the same. The vehicle has set diagnostic trouble code p0722 for the transmission output speed sensor. I have been informed that the output speed sensor is molded into the transmission lead frame and cannot be replaced separately, requiring replacement of the lead frame. Today, the transmission malfunction created an immediate and potentially life-threatening safety situation. As I pulled out of my driveway, the truck remained in 1st gear and would not properly progress through the gears. It then abruptly jumped into 2nd gear and caused the vehicle to stall/lose forward progress while I was entering the roadway. Oncoming traffic was nearly upon me and I was almost struck. The vehicle eventually engaged the proper gear and continued moving, but by that time I was in a dangerous, life-threatening situation. This is not an isolated incident or an occasional inconvenience. The transmission has been repeatedly malfunctioning, including going into limp mode in 5th gear and failing to downshift appropriately when stopping. The vehicle's inability to properly select and engage the appropriate gear creates a serious risk when pulling into traffic, stopping, accelerating, or attempting to avoid another vehicle. Ford has a customer satisfaction program related to the transmission lead frame/output speed sensor issue. However, I was told that my vehicle is not covered because p0722 is not one of the diagnostic codes included for coverage.

57 Power Train problem of the 2017 Ford F-150

Failure Date: 09/06/2026

The vehicle has a ten speed transmission. It started with the transmission making minor down shifts from 3 to 1 and then 7 to 1. Without any engine warning light. It has subsequently started a severe shift from 3 to 1 and 7 to 1 and the engine light has now come on. This creates a dangerous situation when it down shifts from 7-1 when your speed is 45 mph of above. I contacted a dealership regarding a repair but was told there is no recall and it would cost $215 to diagnose and from $4,500 - $8,000 for the repair. It is a known issue to the Ford dealers but without a recall they are gouging the consumers who is at risk of accident.

58 Power Train problem of the 2020 Ford F-150

Failure Date: 09/06/2026

Truck suddenly shifted from gear 8 to gear 2 then 4 reducing my speed suddenly causing other vehicles to almost hit me at around 40 mph. I drove home with the transmission erratically shifting up and down even though I kept my speed under 30 mph. That was about 10 days ago and I made an attempt to drive it a few days ago after researching and in the same result happened. It seems I have been victimized by the cdf drum crawling out of its space leading to an imbalance of transmission fluid pressure. About 2 miles after the initial problem. A wrench symbol appeared on the instrument cluster with a message under it that says see manual. Just as every time I've tried to find something in the manual. After spending several minutes of frustration, I still never found the wrench symbol or what it means.

59 Power Train problem of the 2017 Ford F-150

Failure Date: 09/05/2026

My vehicle's transmission changed gears suddenly and unexpectedly causing a slight difficulty to control. Following the sudden gear change, some lights on the dashboard began flickering erratically. I have video of the dashboard after the gear change. For this incident, I was driving about 25 mph. I experienced similar behavior before and at highway speeds. Since then, the vehicle was serviced by Ford for a safety recall notice 26s28/NHTSA recall 26v237. The service performed under the recall did not fix the problem. The local Ford dealer told me they would charge me to have the problem investigated, so I have not brought the vehicle in to them.

60 Power Train problem of the 2024 Ford F-150

Failure Date: 09/05/2026

61 Power Train problem of the 2023 Ford F-150

Failure Date: 09/04/2026

2023 f150 28k miles. No warnings. Continious issues with severe transmission shifting, loud clunk and jerking/whiplash and failure to engage when first put into gear. Shudder at times around 55 mph, reared backlash issue identified but within tolerance per dealership. Transmission was rebuilt resulting in more sever shifting at high speeds 10-9-8 and 3-2-1 down shifting.

62 Power Train problem of the 2017 Ford F-150

Failure Date: 09/04/2026

The contact owns a 2017 Ford F-150. The contact stated that the vehicle was previously repaired under NHTSA campaign number: 26v237000 (power train); however, the failure occurred after the recall repair. The contact stated that while driving at an undisclosed speed, the transmission started slipping. The dealer was made aware of the failure and informed the contact that a diagnostic test was needed to determine the cause of the failure. The failure mileage was approximately 93,000.

63 Power Train problem of the 2016 Ford F-150

Failure Date: 09/02/2026

Ford mailed me a xxx customer satisfaction program 26n04 letter for my 2016 F-150, VIN [xxx]. That letter offered a one-time, no-charge replacement of the transmission molded lead frame if the dealer determined replacement was needed, and it described a malfunction indicator lamp and/or wrench light when that part fails. My truck did exactly that. It stored p0715 and p0717, went into limp mode, and the wrench came on. Titus-will Ford in tacoma confirmed the turbine speed sensor is part of the lead frame and replaced it (part al3z-7g276-d). They denied 26n04 because those codes are not p0705, p0706, p0707, or p1702 — a code list the customer letter never disclosed. The failed part is the part named in your letter. The symptoms are the symptoms named in your letter. I paid invoice xxx dated xxx. The lead-frame line was $1,630. 02. Information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

64 Power Train problem of the 2016 Ford F-150

Failure Date: 09/02/2026

I would like to file complaint against Ford for their latest recall (26n041) and how they are not doing replacing the defective lead frame in customers vehicles. It's a big scam and a waste of time. I brought my 2016 Ford F-150 in for Ford’s latest recall (26n04) affecting 2015–2017 models due to the transmission leadframe issue. I explained that I’ve been dealing with an intermittent problem for the past seven months: while driving, the gear indicator lights on the dash begin to flicker, and when that happens, the transmission shifts extremely hard and slams into the next gear. Ford kept my truck for a week and told me they were unable to duplicate the issue. They stated that multiple technicians drove the vehicle and none of them observed any problems. When I arrived to pick it up, I was handed a bill for more than $250 for a diagnostic fee. Within four miles of leaving the dealership, the gear indicator lights began flickering again. It’s difficult to accept that several technicians drove the truck over multiple days and never encountered the issue I experienced almost immediately. The entire process felt like a waste of time and money, and I’m left without any resolution to a problem that clearly still exists. They are not honoring the recall, they are trying to charge customers for the repair.

65 Power Train problem of the 2014 Ford F-150

Failure Date: 09/02/2026

Keeps going into limp mode, codes are pointing to lead frame, a lot of sensor a codes. Rough shifting from 1st to 2nd as well as sudden down shiffting.

68 Power Train problem of the 2017 Ford F-150

Failure Date: 09/01/2026

In 2025 my 2017 Ford F-150 started randomly downshifting. We took the car to the Ford dealer who could not assess what the problem was exactly (rowe Ford in westbrook, maine). They suggested a new transmission to be safe and clearly indicated that this was not a safe truck to drive at the time. We took the truck to another Ford dealer to try to get an actual determination of what was wrong (casco bay Ford, maine). They also advised that no codes were being given but that the truck was clearly downshifting and not safe. With no real alternatives or clear problem, we paid $8,000+ for a new transmission. Then, months later we get the recall notice: (campaign 26s28 / NHTSA recall 26v237) - Ford F-150's were downshifting. . . We had Ford do the software update as this is now a new transmission, but when we asked about the recall and if there was anything we could do about the $8,000 we just paid lower and upper management (we talked to both) advised that because they could not definitively put a label to the problem before we fixed the transmission that they could not attribute the downshifting to the same problem and so will not help or otherwise reimburse us for the cost of having to fix the problem that was recalled later. No remedy was offered by Ford.

69 Power Train problem of the 2015 Ford F-150

Failure Date: 09/01/2026

While driving my 2015 Ford F-150, the vehicle experiences a severe and hazardous transmission defect. The transmission unexpectedly drops out of gear while in motion, resulting in an immediate loss of power and acceleration. Simultaneously, the 'd' (drive) gear indicator light on the instrument cluster goes dark, and both the wrench warning light and check engine light illuminate, forcing the vehicle into an unsafe limp mode. This vehicle is subject to active safety recall 26s28 / NHTSA 26v237 regarding unintended transmission downshifts and transmission range sensor signal loss. I contacted an authorized Ford dealership to have this federally mandated safety recall performed. However, the service department explicitly refused to execute the recall repair, stating that the recall procedure does not solve the problem and makes it worse. The dealership is refusing to perform the required safety service, leaving my vehicle unrepaired and creating a dangerous ongoing safety hazard on public roads.

70 Power Train problem of the 2019 Ford F-150

Failure Date: 08/31/2026

We were about 75 miles from the destination when going down hill the transmission would not shift to the lower gear until we were going to fast and then it would down sift very hard. While going up a hill it would down shift ok but as we got up to speed the transmission would not shift up but stay in the lower gear. Finally at very high rpm it would shift up to the higher gear with a very loud clunk. As soon as we got to our destination we took it to a Ford dealer and they said we were lucky because the transmission was on verge of failing completely. Ford has a 60k power train warranty and they said even though it was less than 60k miles my warranty ran out of time 6 weeks ago. If the transmission had failed completely, the car could have had a major safety issue with the trailer behind us. We were not pulling weight more than rated but going up the mountains and the down with only brakes would have been very dangerous. I read that many Ford owners are having problems with their 10r80 ten speed transmission in the larger heavy vehicles such as expedition or f150. Ford authority reported expeditions pulling trailers have the 10r80 transmission failing after 30k miles.
