Power Train Problems of Ford F-250 - part 1

Truck shifted into 10th gear at about 55 mph on flat four lane road near wilmington, nc, powertrain malfunction (wrench) indicator illuminated, and there was a significant reduction in engine power. This occurred twice on 11/9/2026. Loss of power impacts my ability to stay with flow of traffic and loss of power, and speed, without any braking increases risk that vehicles behind me will not be warned of my speed reduction increasing the probability of rear end collision. Truck has not yet been to dealer for this issue but manufacturer acknowledges this defect in TSB 23-2160.

My vehicle has been at Ford of harvey since 8/31/26. Dealer replaced ignition coil 8/18/26. Light and rough idle returned and the dealer determined a new engine would be needed. Dealer says Ford warranty only wants to replace cam shaft. Metal in oil was found and dealer has fought corporate warranty for over a month, ripping apart my engine. The fear is engine could seize at highway speeds as a result of internal damage. Caused by circulating debris. Truck still sits at dealer.

On October 9, 2026 at approximately 8:30 am, my 2019 Ford F-250 6. 7l power stroke diesel, with 76,512 miles, suffered a catastrophic high-pressure fuel injection pump failure while traveling approximately 55 mph on fm 3351 near camp stanley, texas. The vehicle displayed “speed limited” and “reduced engine power” warnings, then lost throttle response and propulsion and the engine shut down while moving. Steering and braking effort increased substantially after the engine stopped. The truck would crank but would not restart. Alamo diesel service, an independent diesel repair facility, confirmed no fuel-rail pressure, fuel leaking in the engine valley, and that the injection pump had “blown and cracked the head. ” inspection revealed metallic debris and extensive fuel-system contamination requiring replacement/repair of the pump, injectors, rails, fuel lines, return lines and filters, plus cleaning of the tank and cooler. The estimate is $11,193. 97. Diagnostic codes included p0087 (fuel rail/system pressure too low) and p2291. P0087 freeze-frame data recorded the vehicle at 54. 68 mph and 1,300 rpm, confirming the fuel-pressure failure occurred while driving. There were no prior fuel-system problems and the fuel filters were recently replaced. I am concerned because there is a long, documented history of failures involving this type of high-pressure diesel fuel pump, including failures that can introduce metal into the fuel system and cause loss of propulsion. Ford has also recalled certain later-model 6. 7l super duty trucks for high-pressure fuel pump failures that can cause loss of drive power. I am requesting NHTSA evaluate whether my 2019 failure may be related to a broader safety defect. Ford has been notified under case cxh-09644112-l1w2n0 but has not inspected the vehicle. The vehicle and failed components are currently available for inspection.

Pulled into my driveway, put vehicle in park and vehicle rolled away. Dealer says transmission needs to be replaced. Nhtsa bulletin 22s22 is a roll away risk for 2020 F-250 but my VIN is not included in this recall but I fear more vehicles were affected by this then what Ford reported.

The contact owns a 2018 Ford F-250 sd. The contact stated that while driving, the vehicle was vibrating abnormally. The contact researched and became aware of NHTSA campaign number: 22v087000 (structure, power train); however, the VIN was not included in the recall. The manufacturer was notified of the failure. The failure mileage was 85,000.

My 2020 Ford F-250 super duty suffered failure of the high-pressure fuel pump resulting in catastrophic engine failure directly caused by the unperformed defect targeted under Ford safety recall 24s78 / 26s17. The vehicle went into limp mode in the middle of the road while driving. There was no warning, and the vehicle had no previous check engine lights or issues. The Ford service department has physically inspected the vehicle and confirmed the presence of metal shards and mechanical contamination inside the engine and fuel system, which is the definitive physical proof of failure of the high-pressure fuel pump. Despite physical proof Ford refuses to provide the mandated free recall remedy or cover the consequential engine damage justifying the denial strictly on a electronic reporting technicality. They are saying that if the vehicle doesn’t show specific engine codes, then they will not cover repairs. This denial makes no sense because an independent mechanic already verified and recorded the required diagnostic codes before the truck arrived at Ford. I believe that Ford is intentionally and systematically masking/ filtering out engine diagnostic codes to avoid paying for the damage cause by this unperformed recall. I believe that this is unethical and potentially illegal. From my research I believe that Ford altered computer thresholds, programming Ford's proprietary diagnostic system to filter out or ignore raw pressure drops that standard, independent obd-ii code readers immediately catch. Additionally, Fords own service manager explicitly stated she believes the engine damage was caused by the recall. She even submitted a special service center assistance request despite not having the codes, because she believed it would be approved due to the physical and mechanical evidence of the engine failure. I also visited another Ford service center where the manager said that he was having the same problem with Ford rejecting engine repairs linked to this recall.

Transmission, temporally could be available but to replace it there is a $1500 core charge the transmission catastrophically failed, which lead to the rear wheels to lock up while driving, putting me and others at risk, had I been going faster when it did lock up no the problem has not been reproduced by a independent service center as I am going to replace the transmission myself I have inspected it along with a mechanic via photos showing all the metal fragments in the fluid and filter no warning lamps prior to the failure, but there where warning lights of service vehicle soon before the transmission locked up. Ever since new the transmission has shifted erratically especially from 3-4 and 6-7. Ford told me this was normal when I brough it in back when it only had a 20 or 30k miles on it for the erratic shifting. I now have 76k miles.

Subject: request for review of recall remedy effectiveness – Ford recall 24s78 / NHTSA recall 24v-957 vehicle: 2020 Ford F-250 super duty 6. 7l power stroke VIN: [xxx] to whom it may concern: I am submitting this letter to document a significant safety event involving my 2020 Ford F-250 super duty and to request that NHTSA consider whether the current recall remedy associated with Ford recall 24s78 / NHTSA recall 24v-957 adequately addresses vehicles that are already exhibiting symptoms of cp4 fuel pump deterioration. I am not submitting this complaint to seek financial compensation. My purpose is to provide information that may assist NHTSA in evaluating whether the existing remedy sufficiently protects motorists from the safety risks associated with cp4 pump failure. Background my vehicle's VIN has been confirmed as included in the affected population covered by the cp4 fuel pump recall. Prior to the ultimate failure, the vehicle exhibited symptoms that, in hindsight, may have been indicators of fuel-system deterioration. In February 2026, I documented concerns regarding abnormal starting behavior and specifically questioned whether either vehicle battery was failing. No battery issue was identified. Believing the issue might be battery related, I replaced both batteries at my own expense. The starting concern continued. On [xxx], while covered under a Ford extended service plan, fuel injector #4 failed and was replaced under warranty. During the same service visit, the recall software update was performed. Despite the recall remedy being completed, the vehicle subsequently suffered a catastrophic cp4 pump failure in August 2026. Safety event the failure occurred while traveling between utopia, texas and tarpley, texas on a rural roadway with sharp curves, steep terrain, significant drop-offs, and little or no roadway shoulder. The vehicle experienced a sudden loss of propulsion. Fortunately, I had just exited a curve and was able to information redacted pursuant to the freedom of information act (f.

I am filing a complaint against capital auto mall premier regarding the sale of a 2019 Ford f\-250 lariat \(VIN [xxx]\) that I purchased on xxx. The vehicle was represented as being in good working condition at the time of sale. However, almost immediately after taking possession of the vehicle, I began discovering numerous mechanical, electrical, and safety\-related defects. Due to the number of concerns, I had the vehicle independently inspected shortly after purchase. The inspection identified multiple significant issues, including transmission hard shifting, transfer case clunking during shifting, battery failure requiring replacement, steering and suspension concerns, excessive play in front suspension components, and numerous diagnostic trouble codes stored in the vehicle's systems. In addition to these findings, I discovered issues involving vehicle lighting, winch operation, and other features and equipment that were not functioning properly despite being expected to be operational at the time of sale. These issues became apparent within days of purchasing the vehicle. The quantity and severity of the defects lead me to believe that the vehicle was not in the condition represented during the sale and that material defects may not have been properly disclosed before the transaction occurred. As a result of these issues, I have incurred costs associated with inspections and diagnostics and am obtaining additional repair estimates to determine the full cost of necessary repairs. The defects significantly impact the vehicle's safety, reliability, usability, and value. I have supporting documentation, including the purchase agreement, financing documents, independent inspection reports, diagnostic findings, photographs, repair estimates, and records of communications regarding the vehicle. This documentation demonstrates that the concerns were identified almost immediately after purchase and were not the result of normal wear occurring information redacted pursuant to the freedom of information act (foia).

After the vehicle was jumpstarted the vehicle failed to correctly enter gear- when shifting into reverse it instead rolled forward downhill. The following systems also displayed failure warnings: abs traction control parking brake ( parking brake also showed as activated when it was not active- it would audibly disengage but the parking brake light stayed lit) stability control 4wd. The combination of the parking brake showing as active and the shifter showing the vehicle was in reverse while being able to roll forward freely is dangerous.

At around 139,000 miles I started to noticed some intermittent noise coming from the drivetrain. I took it to two different repair shops and was told it was tire noise. Over time the grinding noise increased to the point of shuddering and jerking while shifting with no warning lamps showing. At 144,500 miles I contacted my aftermarket warranty and they said to take it to a certified shop to get it checked out. They did not have any preferred shops in my area so I took it to us automotive. At 145,000 miles the shop contacted the warranty company and proceeded with investigation of the issue. After inspection and tear down they confirmed the transmission had the typical failure for the 10r80 10-speed automatic transmissions. They turned over there findings and the warranty company which has agreed to the findings and has offered a replacement used transmission with 125,000 miles on it and will also not cover the full cost to install the used unit. I feel that this is fraud and outside of the warranty agreement. I am now paying the expense to put the original transmission back into the truck to try to take it the 2. 5 hours back to the dealership which sold me the truck along with the warranty to see what they will do in the matter. I hope it doesn't fail on the highway on the way.

Def heater failure will cause increased emissions. The warning light flashes. I have seen details where there are issues with the wiring harness for the def heater.

The contact owns a 2020 Ford F-250. The contact received notification for NHTSA campaign number: 22v256000 (power train); however, the recall repair could not be completed. The vehicle was taken to a dealer where it was diagnosed that a thrust washer was missing from the output planetary assembly and had disintegrated, contaminating the transmission case, transfer case, torque converter, cooling lines, and radiator. The missing washer caused the planetary gear to shift and damage the transmission case. The manufacturer was notified of the failure, and a complaint was filed. The failure mileage was 80,256.

10r140 paired with 6. 7 powerstroke in a 2020 f250 build date 11/19 at the kentucky plant. My truck specs and build date and location is in the timeframe of the planetary gear recall, Ford has also issued TSB’s about the cdf bushing that should have been a recall because it is a design flaw on every 2020-2022 model truck. It’s not fair that we should have to pay for a TSB bc we don’t have warranty left. My truck has 84,000 miles but is out of the 5 years warranty period. Symptoms I am having with my transmission are: harsh engaging to drive and reverse flair shifts bad sometimes almost like it goes into neutral between changing gears has shifted from 4th to 1st instead of 4th to 5th or 6th, then it started shifting normal right after. Had my factory 3250rpm limiter not been moved to 4500rpm the truck would have locked the rear wheels up and possible caused driveline damage or other damaged. Also had a car been behind me when this happened I would have been in a wreck because it slammed to a low speed and the car would have rear ended me. Slips in 4th and 7th gear the most but sometimes in other gears bumps when it shifts a lot of the gears sometimes shudders and shakes and will almost make like a pop noise will clunk on downshift from 5-3 sometimes clunks when upshifting 3-5 I have had the truck looked at by an independent diesel mechanic I use and he said there is a problem somewhere in the transmission, it’s either planetary gear or cdf bushing has moved or the drum itself has cracked. The component itself has not been inspected because the only was to inspect this is to tear the transmission down. The pan has been dropped and had a lot of metal material on the magnet. No codes on the dash but my mechanic said I had dtcs stored for the transmission. I have created a case claim with Ford trying to see if they will extend the recall for the known issue but I have had zero luck with them. I have videos of the issues but can’t upload them on here.

I was driving from [xxx] back to [xxx] on I-5. I was at 70mph when a slower vehicle merged into my lane and I got on the gas to pass them. The transmission locked into 10th gear and never downshifted, the engine revved, and then I lost complete power of the transmission for several seconds. I went from 70 to 55 and then it jerked back into gear. I had my 2 small kids in the back seat and wife in the truck. This happened to me with my 2020 f-150 when my wife was pregnant and then eventually got worse and worse. My transmission shifts hard when put in gear and most times will lurch forward. It bogs down in 4th gear a lot and lately all the way through 6th gear. Doesn't happen all the time but enough to worry whether its safe to keep driving with my family in it (only vehicle in the family). Information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

Transmission has shifting issues. Sometimes is don't down shift below 4th gear and when in an intersection truck barley moves then it shifts hard and can move . It also is constantly shifting between gears. It will shift form 10th to 5yh while driving.

I was on an overpass in the left hand lane doing 40-45mpg getting ready to make a left hand turn on an expressway on ramp. I coasted for just a bit and applied the brakes gently, then a little more. The truck was not slowing down like it should have so I applied alot more brake pedal pressure and it slowed down some then it down shifted several times and the engine was roaring, I'm guessing around 3k rpms or more and pulling me forwards. I put as much pressure as I could on the brake pedal and got it down to 4-5 mph and then as it was almost at a stop, still with the motor roaring, I slammed it into park and turned the key off. The motor turned off thank goodness. I sat there for about 20 seconds or so, luckily no one was behind me, then I turned it on again and it was idling just fine. I crept through the intersection and proceeded down the on ramp at 10mph or so and pulled over. Turned it off again and called the wife and a few friends about it. It ran ok, albeit I was super cautious, to my destination 25 minutes on down the highway. Something freaked out big time in the computer. Had there been traffic or someone in front of me it would have lead to a serious crash.

My truck transmission changes gears randomly while in motion. It is terrifying when it happens in traffic and the truck stalls and looses power then kicks back in with a loud noise. I stopped driving it since March of 2026.

Driving while pitman arm broke in half lost total control.

Sometime sudden decrease of power , f250 truck rpm goes high while parking with engine on and now pitman arm broke off causing no control of steering . Having it push safely off the road , contact dealership but no parts to fix and timely how long it takes to get part to fix problem. 2020 Ford f250 start but very unsafe to operate with no control of the steering.

The vehicle experienced a sudden loss of motive power and became inoperable due to failure of the high-pressure fuel system. This VIN is subject to an active safety recall (NHTSA 24v957 / Ford 24s78) addressing high-pressure fuel pump failure that can result in loss of motive power while driving. Prior to failure, the vehicle exhibited reduced engine performance and drivability issues consistent with fuel system malfunction. No water-in-fuel warning or alert was displayed prior to the failure. The vehicle was inspected by an authorized Ford dealership. Ford and the dealership asserted “fuel contamination” as the cause and refused to repair the vehicle under the recall or warranty unless the customer paid for diagnostic teardown. The recall repair was not performed. The vehicle remains unrepaired and was removed from the dealership. The loss of motive power created a safety risk to the occupants and other motorists. We are concerned that a recalled safety defect affecting the fuel system is not being remedied and is being mischaracterized to avoid recall repair.

This is a follow-up to my original complaint #xxx, filed xxx, regarding the failure of the 10r140 10-speed automatic transmission in my 2021 Ford F-250 super duty (VIN: [xxx]). The transmission began exhibiting symptoms of gear slipping, jerking, delayed and harsh shifting, and pinging from the torque converter around 100,000 miles. These symptoms progressively worsened until the transmission suffered a catastrophic internal failure. As documented in the attached sid dillon Ford repair order, an authorized Ford dealer found metal contamination in the transmission fluid and confirmed that a complete transmission replacement was required. The attached friesen Ford repair order also shows that harsh engagements were present and that a transmission flush failed to resolve the issue. I have also attached a sworn statement from [xxx], an independent automotive technician who has serviced vehicles for my family for several years. In his sworn statement, he confirms that these 10r140 transmissions have known serious ongoing issues and that many mechanics avoid working on them due to these problems. Ford motor company was provided with the above repair records and the sworn statement but has denied any responsibility or reimbursement for the transmission failure. The failure created a serious safety risk due to the sudden loss of propulsion while driving. Information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

Vehicle was parked on a hill. At the time the vehicle was pulling a light weight trailer (empty). The vehicle was in park when the engine was shutoff. Owner went inside the house, came back out 5 minutes later to find the vehicle had rolled unattended backwards causing the trailer to jack knife. The result was damage to the truck and trailer. This was very lucky considering another vehicle could have come over the hill and hit the truck and trailer and people could have been injured. This is the third instance of this truck rolling unattended. I have contacted Ford, written complaints. A recall was released that fixes a known transmission issue with near VIN numbers but it does not effect this vehicle. Please help.

2020 Ford f250 with 85,000 miles. We purchased new and all maintenance has been done on time and by Ford service. Transmission began jerking when going from park to drive (or reverse). Noticeable lunging of the vehicle when putting into gear. This began in December 2025. This is a safety concern if anyone is in front of or behind the vehicle when this happens. The truck jumps. Now the transmission is not shifting gears smoothly when the truck is in motion. This is a known problem with trucks manufactured during this time period with 10r80 transmissions. Ford has been less than helpful in helping me come to a resolution. They tell me there was a TSB sent out. They attempted to reprogram software (at a cost of $424 to me). I will upload the invoice from Ford. This only made the problem worse. They quoted me a "special price" of $8,500 to replace the transmission, however their service department is six weeks out. For this reason we have chosen to have the transmission replaced at a local transmission shop. Their price is $9,932. 41. I have attached that invoice. Ford needs to take accountability for this safety problem and attempt to make these vehicles safe. They should absorb at least some of the cost to fix this design problem. We paid full price to purchase a new, safe vehicle. That is not what we received. Rather than a "technical service bulletin", Ford should be forced to do a recall and make this right for customers who paid top dollar for these vehicles.

Subject: safety recall 24v-957 – loss of power risk – dealer mishandling I am filing a complaint regarding Ford recall 24v-957 (Ford reference 24s78) for my vehicle. The recall states the defect can cause: “loss of driving power, increasing the risk of a crash” “engine stall” “loss of motive power while driving” my vehicle has shown symptoms consistent with these safety risks. When I brought the vehicle to the dealership: 1. They claimed fuel contamination but provided a fuel sample with a Dec 3 timestamp, even though they originally claimed the issue was discovered on Nov 26, raising chain-of-custody concerns. 2. They have refused to properly address the recall or escalate the matter. 3. They threatened to report my rental car as stolen, even though I have not refused to return it and the vehicle is still under an unresolved recall safety issue. 4. Ford customer care refuses to intervene and instructs me to deal only with the dealership, despite this being a manufacturer safety recall. This situation has left me without clear direction, without safe transportation, and with concerns about dealership misconduct and improper handling of a safety-critical recall. I am requesting NHTSA review this recall handling and ensure Ford properly manages recall repairs, towing, rental support, and dealer oversight.

Violent shaking when driving at high speeds and after hitting bumps or uneven streets.

The contact owns a 2020 Ford F-250 sd. The contact stated that while the vehicle was stopped at a traffic light, the transmission failed to downshift from seventh gear, causing the vehicle to jerk. The transmission warning light was illuminated, and the message "power train malfunction - reduce power" was displayed on the Ford mobile app. The contact's neighbor, an independent mechanic, diagnosed the vehicle and determined that the transmission needed to be replaced. The vehicle was not repaired. The contact related the failure to NHTSA campaign number: 22v256000 (power train); however, the VIN was not included in the recall. The manufacturer was not made aware of the failure. The failure mileage was approximately 100,000.

The contact owns a 2020 Ford F-250. The contact stated that while entering light traffic, the transmission became stuck between gears. The accelerator pedal was depressed, but the vehicle failed to respond or move. The vehicle was restarted and worked as designed. There were no warning lights illuminated. The vehicle was taken to an independent mechanic who determined that the failure was related to the transmission. The mechanic called the local dealer for the contact and was informed that the vehicle was not under warranty. The contact called another local dealer, but the vehicle was not diagnosed or repaired. The manufacturer was not contacted. The failure mileage was approximately 57,000.

Known issue identified with this particular make, model and year truck in 2021; rough shifting, wrench light illuminating, failure to shift gears appropriately, stuck in certain gears risk of stalling, stopping, unable to shift down appropriately inspected by dealer and mechanics Ford document shows planetary needle bearing inside ring gear assembly generates contamination back in 2021/2022; unable to confirm fix was performed on this vehicle.

Recall is 9 months old and still no remedy available. Unable to use truck on platforms such as turo because of the safety risk. No update from Ford, no dealer has a remedy.

Slight vibration at highway speed accompanied by faint grinding noise. Ford installed front auto locker to only one front wheel and a dummy full time locker to right front wheel in non trimmer 2024 f250 and f350s. They know the problem because they issued a TSB 52423 but do not contact truck owners of issue. Having only one locker makes the right side front axel spin at highway speeds and cause noise, vibration and unequal drag on the two front wheels causing the vehicle to drift to the right. Ford knows this, as evident by them going back to two locking auto hubs on 2025 models. My bigger concern is what happens in 100k k miles when the front differential being warn out by the highway speeds fails and locks up the front differential and suddenly locks the front right wheel and potentially sends the 7000 lb vehicle in an uncontrollable right turn. I am currently working with walker Ford to correct this issue with my truck. In my opion, this is a huge safety issue because Ford is aware of this problem but is not notifying owners of the issue with an official recall. Needed fix, replace right dummy locker hub with functional hub like the left side ( part number hc3z3b396a $260), instal replacement volume line (part number hc3z3c124b $51) if said truck does not already have one, and finally install 6 in vacume line (part number hc323c125c $6) to the front right hub. In my opion, Ford should be held fully liable for the human safety implications down the road if they continue to ignore this proplem.

My 2020 Ford F-250 king ranch with a 6. 7l v8 turbo diesel engine experienced severe engine failure while I was driving. The engine was completely destroyed and had to be replaced. My warranty company paid to install a new engine into the truck, but did not pay to have the remaining components fixed that were directly damaged by the engine failure. There was severe damage done to the fuel pump, def system, and wiring harnesses that caused the truck to be permanently into a mode called "limp mode" which electronically governs the truck to 50 mph. There was and still is an unresolved recall on the truck. The recall is as follows: #24s78 powertrain control module software update biodiesel deposit accumulation. The NHTSA number NHTSA: #24v957. There were absolutely zero (0) warning signs that alerted me that this was an issue before the engine failed. No alerts or warning lamps were illuminated on the truck before it failed. All I got was a letter in the mail stating that the engine could fail due to this components and that there is no known solution to fixing the problem. This issue caused my engine to fail while I was driving to work. There are issues with the truck still that were directly caused by this issue that the warranty will not cover including this recalled component that has no available solution. I have a 2 month old son and a wife that rely on me having this truck. I have risked the safety of my family, and others on the roads, unknowingly by operating this truck on the roads. I am asking that Ford motor company be held liable for all damages to my truck, and the repurchase of the truck for full price. This is unacceptable from a company as big as Ford motor company.

Bushing in cdf drum has moved causing failure to transmission. This appears to be a common issue. When this occurred truck would not engage in certain gears at slow turns and stops causing lack of acceleration creating a hazard merging in traffic.

Entire vehicle shakes/wobbles extremely uncontrollably going a speed around 65; have to slow to avoid an accident and put on hazards. Makes our heart stop not knowing what danger we have been put in when it occurs. Very scary and dangerous to ourselves and others. Occurs with roadways involving dips, highways, ridges of bridges such as bumps or gaps, and/or differences in road, etc. This has occurred multiple times. ([xxx]) was another episode. This is scary dangerous! no lights or indications go off. Information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).
