2020 Ford Expedition: transmission slipping

Filed Oct 26, 2026 · Transmission · MI

When accelerating hard, the vehicle attempted to downshift the transmission, but failed and all power was suddenly lost. Vehicle transmission was loud and grinding. Warning lamps stating Shift failure was displayed but disappeared quickly. After removing acceleration, transmission seemed to slip into gear and normal acceleration was restored. About 30 seconds later when holding constant speed, vehicle suddenly jerked and downshifted unexpectedly, again grinding could be heard and RPM's shot extremely high. Again foot was removed from acceleration and normal driving was restored.

The 10 speed transmission has ALWAYS slipped and never shifted correclty. Taken to shop multiple times and was told thats just how the transmission changes on the newer Ford 10 speed transmissions. Had the car 3 years and now I got a code saying the transmission is slipping in between 9-10 gears and 3-4 gears. The truck has ALWAYS done it but now it's gotten worse and no WARRANTY. Looks like THOUSANDS or millions have this problem and no clue how I'm responsible for a faulty transmission Ford knows is bad on their side. Terrible customer service where this is not fixed under a recall until the warranty is out and UNABLE to fix now. UNACCEPTABLE! If Ford would've fixed it earlier before it was completely gone, I'd have my $10,000 back. And why does Ford have a transmission that most transmission shops will not work on and costs that much money to replace. I'm DONE with Ford and their products!

Was trying to merge into traffic by accelerating but the transmission was not shifting properly or slipping which caused me to almost be in a wreck due to this problem. Took vehicle to dealer and was told the transmission needs replaced due to a cdf drum inside transmission. Said there is a tsb for the issue but no recall. Said it's a known issue but I have to pay for a new transmission. Also have issues with the park brake setting while still moving which will also damage the transmission and there is a recall for that but no remedy yet. Why would I put a new transmission in and pay for it when it still has the park brake issue that will damage the new transmission. Afraid to drive the vehicle with these problems but paid a huge amount of money for it to just sit in the driveway

My name is [XXX] [XXX] and i own a 2020 Ford Expedition Limited Max, there is a recall to inspect transmission recall#26S48/26V402. I contacted Ford dealer and stated there is no fix yet, I asked them what do i do in the meantime, stated i have to wait until Ford figures out the fix. So, in the meantime, we have to continue driving this vehicle with this known issue/safety concern and hope that it does not do it again and cause an accident or god forbid something happen to my family. This is my wife's daily driver with our 4 kids; the vehicle has done this twice where it goes into park while still driving on its own. Luckily both times we were only going about 15MPH, had to turn the vehicle off to be able to turn it back on. This cannot be good for the transmission; the transmission constantly slips i believe as a result now and when i try to accelerate quickly it hesitates. If i wasn't going to be upside down i would trade it in but unfortunately i can not at the moment. I would like to see something done to fix the issues with this vehicle. Aside from this i have had constant AC issues, the center console trim cut my wife's finger, the running boards sometimes come out, it's an ongoing battle with this vehicle. I would for Ford to fix these issues or buy the vehicle back. Please let me know something, rather it be to fix these issues or buy it back, if i don't hear backi will be consulting a lawyer next.

Recurring dangerous transmission defect in my 2020 Ford Expedition (3.5L EcoBoost, 10-speed 10R80, ~136,826 mi). It has lost power and shifted violently multiple times, each a crash risk. 1) ~Aug 22, 2026: Accelerating to pass on the highway, the whole vehicle shut down. I lost all power INCLUDING power steering and had to coast off the road. It restarted after stopping. Losing power and steering while passing at speed is extremely dangerous. 2) Weekend of ~Aug 29-31, 2026: Going up a slight residential driveway, the transmission slipped (engine revved, vehicle didn't move) then slammed into gear with a hard jolt. 3) Another time, accelerating to pass, it made an extremely loud bang and violent jolt; I thought the transmission had failed. ONGOING since I bought it used (June 2023): it repeatedly slams/clunks hard into gear, including while just coasting down a slight grade with NO foot on gas or brake, jolting violently as if it dropped into Park. This is not just my vehicle. The 10R80 transmission (2020 Expedition, F-150, etc.) has many complaints for the same thing (sudden downshifts, power loss, harsh shifting, slipping) and is subject to a class action (filed 4/2023, MA) covering 2017-present F-150/Expedition/Mustang/Ranger/Navigator, alleging Ford knew since 2018. I raised this repeatedly with Ford and two dealerships and was told there were no recalls and no known issue. Ford's open recall 26S48 (26V402) is only about the PARKING system and does NOT cover this loss-of-power/violent-shift behavior. Please investigate.

My 2020 Ford Expedition has a transmission problem. The vehicle has harsh shifting, slipping, hesitation, jerking/lunging, and abnormal shifting while driving. The problem happens during gear changes and creates a safety concern because the vehicle may hesitate, slip, or shift unexpectedly in traffic. I took the vehicle to the dealer for inspection. The technician diagnosed the issue and recommended replacing the transmission. I believe this may be related to a known Ford 10R80 10-speed automatic transmission defect. I am requesting that the federal safety agency review this complaint and investigate this safety issue.

The vehicle has experienced repeated critical transmission failures and currently has four active Federal Safety Recalls with no available remedy. The transmission has failed four separate times, requiring four transmission assemblies within approximately 68,795 miles. The latest failure produced DTC P07F7 (Gear 10 Incorrect Ratio) and was confirmed by the Ford dealer and an independent inspector as an internal transmission failure. Symptoms included harsh engagement, delayed shifting, hesitation, slipping, and repeated powertrain malfunction messages. The vehicle was out of service for 26 consecutive days during the most recent repair. A the federal safety agency VIN lookup shows four active unrepaired recalls: a transmission rollaway hazard affecting the parking system (26S48), two seatbelt pretensioner recalls involving inadvertent deployment or failure to retract (25S31 and 26S34), and a chrome trim recall involving sharp edges (26S38). All four recalls currently have no remedy available, with estimated repair dates extending into late 2026 and 2027. These defects affect critical safety systems including the power train, seat belts, and parking system. The rollaway hazard recall indicates the vehicle may move unexpectedly even when shifted into Park, creating a serious risk of injury or collision. The seatbelt pretensioner recalls involve components that may deploy without warning or fail to retract, increasing the risk of injury in a crash. The chrome trim recall involves sharp edges that may injure occupants. Combined with repeated transmission failures, these issues create multiple simultaneous safety risks. The problems have been confirmed by the Ford dealer and an independent inspector. Warning symptoms occurred before each failure, including harsh shifting, slipping, hesitation, and powertrain alerts. The combination of unresolved Federal Safety Recalls and repeated transmission failures makes the vehicle unsafe to operate.

The contact owns a 2020 Ford Expedition. The contact received notifications of the federal safety agency Campaign Numbers: 26V344000 (Seat Belts), 26V368000 (Structure), 26V402000 (Power Train); however, the parts for the recall repairs were unavailable. The contact stated the manufacturer had exceeded a reasonable amount of time for the recall repairs. The contact stated that while driving at various speeds, the transmission started slipping. After releasing the accelerator pedal and slowing down, the engine made a revving sound, and the transmission failure was self-corrected and shifted to the proper gear. While starting the vehicle or while driving at various speeds, the transmission hesitated shifting into the intended gear. There was an unknown warning light flashing on the instrument panel. The contact stated that after purchasing the vehicle in March of 2026, the Carfax report stated that the transmission had been replaced, and the contact purchased the vehicle under the belief that the vehicle was equipped with a new transmission. In May, the vehicle was taken to a certified mechanic, who diagnosed the vehicle and determined that the valve body had failed and needed to be replaced. The vehicle was not repaired. The contact emailed the dealer about the diagnostic results and the needed repair. The dealer confirmed the failure. The dealer replaced the valve body, but the failure persisted. The dealer then diagnosed in June that the transmission had failed and needed to be replaced. The vehicle was not repaired. The manufacturer was not made aware of the failure. The failure mileage was 88,467.

Failed Component & Availability: Ford 10R80 10-speed transmission (Power Train). Available for inspection upon request. Safety Risk: My family is put at extreme risk in two ways. 1) Sudden loss of motive power, slipping, and violent engagements at highway speeds create an imminent rear-end collision risk. 2) This exact vehicle is now under Safety Recall 26S48 (the federal safety agency 26V402) for unintended vehicle rollaway. Ford explicitly states a remedy is not available until Q2 2027, forcing us to drive an unfixable, inherently dangerous vehicle for another year. Confirmation & Inspections: Yes, reproduced and confirmed by Tomball Ford. The latest catastrophic internal failure was physically inspected and confirmed by an independent Old Republic Auto Warranty inspector. The Tomball Ford technician explicitly documented the cause as "outdated internal components" aligning with TSB 25-2476. Warnings & Symptoms: Violent shifting, delayed engagement, and "Powertrain Malfunction / Reduced Power" dash warnings. The latest catastrophic failure triggered hard fault DTC P07F7 (Gear 10 Incorrect Ratio). Cause Summary: Chronic manufacturing defect inherent to the Ford 10R80 / 10R60 transmission family. This vehicle has required FOUR (4) transmission assemblies in under 70,000 miles (repairs in Nov 2022, Feb 2023, and June 2026). During the most recent failure (May-June 2026), the vehicle was out of service for 26 consecutive days. Despite 4 failed transmissions and an active unfixable safety recall, Ford Corporate just denied our request for a replacement vehicle, abandoning my family in a documented rolling hazard.

We purchased a used 2020 Ford Expedition Max Platinum, VIN [XXX] , from Deacon Jones dealership. The vehicle currently has 128,888 miles. At the time of purchase, we were assured the SUV was in “tip-top shape” because it had previously belonged to a manager’s friend and had supposedly been well maintained and serviced. However, within only two weeks of purchasing the vehicle, the transmission began slipping out of gear while accelerating, causing the vehicle to lose power and fail to move properly. This is an extremely dangerous safety issue, especially considering I travel frequently to doctors’ appointments and regularly transport my seven grandchildren in this SUV. In addition to the transmission failure, the main electrical system controlling the dashboard frequently glitches and malfunctions, even after Ford performed a software update. These ongoing electrical problems create additional safety concerns and make the vehicle unreliable. We immediately contacted the dealership after the problems began. Their only offer was $750 toward a transmission replacement that will cost over $5,000. We simply do not have that kind of money, especially while continuing to make monthly payments of $850 on a vehicle that is unsafe to drive. We have also since discovered the vehicle had previously been involved in an accident that was never reported to us before the sale. What is most concerning is that this vehicle appears to have received an inspection sticker despite clearly not undergoing a proper inspection. A transmission that slips out of gear and significant electrical malfunctions should never have passed inspection. This places not only my family at risk, but also everyone else on the road. We have written several letters to Ford regarding the safety concerns surrounding this vehicle and the danger it poses to our family. Unfortunately, Ford responded stating they would not assist us in any way. It is extremely disappointing INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 55

We have recurring safety issue with our car that has not been fixed despite multiple service visits to both Grieco Ford and Sawgrass Ford. They keep sending it back as “cannot duplicate”. We have contacted Ford Corporate and they also will not assist. We purchased this car used from Sawgrass ford and purchased an extended warranty with the car. The car issues include: Slipping into Neutral: The transmission unexpectedly loses gear engagement while merging or accelerating on the highway. • Hard Shifting/Clunking: Violent gear changes that cause the whole vehicle to jar physically. • Gear Hunting: The car hesitates and shifts up and down erratically instead of holding a gear. • Limp Mode: Sudden, dramatic loss of power where the car refuses to accelerate properly in traffic. These are serious safety hazards that put our family in harm's way. These failures happen consistently with our children in the car, and they have happened to our teenage son while he was driving. We purchased this car used from Sawgrass Ford. The earliest service documentation I currently have readily accessible showing that this vehicle was brought to Ford for transmission-related concerns is from February 2024—less than seven months after we purchased the vehicle from Sawgrass Ford. Since that time, there has been a significant service history related to this recurring issue.

While merging on to highway vehicle made loud clunk, transmission slipped and vehicle went into fail safe mode(limp mode). Vehicle would not accelerate when pushing on gas pedal for 8 seconds. Tractor trailer truck behind us slammed on its brakes as well as 3 other vehicles due to tractor trailer truck swerving in lanes to stop. Was almost rear ended by tractor trailer truck. Vehicle has TSB’s on 10 speed 10R80 transmissions but no recalls. Vehicle does not throw code so vehicle can not be assessed or repaired according to dealership and Ford motor company. This is a huge fatality risk and safety issue regarding multiple claims of the 10R80 transmissions in the newer ford expeditions.
