What 211 owners told NHTSA about the 2021 Ford Expedition

COMPONENT: 2021 Ford Expedition Max 10R80 transmission. The CDF clutch cylinder (7H351) sleeve exhibits axial movement, breaking the clutch apply-pressure seal so commanded torque is not transmitted to the wheels. Engine revs while the vehicle fails to accelerate or move forward. Vehicle is available for NHTSA inspection and testing. INCIDENTS (7/5/2026, same drive cycle): (1) Highway, after braking from a 60 mph cruise to a 15-20 mph roll over a few hundred feet, the transmission failed to engage any gear on re-acceleration. (2) City, at 35 mph while accelerating to merge lanes, the transmission again failed to engage a gear. Engine 205-220F, Trans 200-210F, Indicated Gears 4th/5th, Odometer 120,217. Second owner; purchased at 115,067 mi. SAFETY: Sudden, unannounced loss of forward propulsion with no dash warning directly endangers my wife, my children, and other motorists during ordinary driving. Merging: stuck at 40-50 mph in 65-80 mph traffic invites a high-differential rear-end impact. Intersections/left turns: a mid-turn stall exposes the passenger side (where my family sits) to a T-bone at posted speed. Evasive maneuvers: failed acceleration converts a near-miss into an unavoidable collision. Grades: the ~7,000-lb SUV can roll backward or stall in-lane on short-sight-line hills. Towing (rated capacity, used regularly) magnifies every risk to trailer and following traffic. Shoulder stranding invites secondary collisions, a known highway-fatality cause. The defect is unpredictable. I cannot pre-empt merges, intersections, hills, or tows. DEALER/INDEPENDENT CONFIRMATION: None. I have not brought the vehicle in for service, to avoid compromising any NHTSA inspection or testing. MFR/POLICE/INSURANCE INSPECTION: None; no crash has occurred to this date. PRIOR WARNINGS: None. No lamps, messages, or symptoms preceded these failures, which first occurred 7/5/2026. Ford has documented awareness of the 10R80 CDF clutch cylinder defect and has not issued a recall.

While driving down the highway at 70 miles an hour, the transmission popped out of gear the engine revved, and when the transmission went back into gear, it engaged into second gear and locked up the rear tires on the highway. I believe this is due to the CDF drum bushing, causing Line pressure problems. But this has almost caused me in my family to get into an accident.

I have taken my car to the shop for constant transmission clunking, loss of power, random shifting causing a safety issue. It is currently in the shop for the 6th time at 69k I bought it new and have taken it in 5 other times for the same or similar issues with the transmission.

NHTSA ODI 11745853

The transmission seems to be sluggish. When making a rolling left turn around 25 to 30 mph after no power to the transmission, when coming out of the turn the trans seems to spin and then slam into gear. I mean slam where everyone in the vehicle says "what the hell was that" kind of slam. This has been intermittent since I purchased the vehicle 1 1/2 years ago at 79,000 miles. I've had the trans fluid changed and that doesn't help. Now at 103,000 it seems to happen more often. I see there are a lot of people in the same boat for multiple years. Shame on Ford. This is my first return to American made since 2 Honda Pilots that ran great until I sold them at 150,000 miles. This is a known issue that is not being resolved by design. Each year their culpability is decreased by the junk yard methodology. Shame on me for buying American.

Hard Shifting & Slipping: Drivers frequently report clunking, hard shifts (particularly around gears 3-5), and the vehicle lurching forward when accelerating. It does this while driving and is a serious safety issue.we complained to the dealer about a year ago and they told us they checked and it was fine. Now it is worse.

The contact owns a 2021 Ford Expedition. The contact stated that while driving at an undisclosed speed, the transmission unexpectedly downshifted and the vehicle jerked abnormally. The contact stated that there was an abnormal sound coming from the vehicle with the Check Engine warning light illuminated. The failure was persistent. The vehicle was taken to the dealer where it was diagnosed with transmission failure. The contact was informed that the transmission needed to be replaced. The vehicle was not repaired. The contact referenced an unknown recall; however, the VIN was not associated with a recall related to the failure. The manufacturer was made aware of the failure but provided no assistance. The contact was informed that the repair was not covered under recall. The failure mileage was approximately 62,500.

Bad parts in the transmission the cdf drum part is not good. While on the highway I was driving and my car lost all power and for about 5-6 seconds lost all power to the car until the transmission kicked into gear. I have has it in for a warranty and they keep saying it nothing then final it went back in and they tell me it the cdf drum in the transmission but this is not a safety concern. It is to me I have 2 kids and if something happens and causes a accident and something happens to my daughter who is replacing my kids no one and Ford will wipe there hands from it. A mandatory recall needs to happen on these transmission and get them fix properly. They did a recall for a piece of trim that cuts when it is lose but they can't do it on this. Unbelievable

“10R80 transmission slips and loses power during acceleration. Matches Ford TSB 23‑2250. Sudden loss of propulsion creates safety risk when merging or crossing intersections.”

NHTSA ODI 11741867

When attempting to pass or slowing and then pressing the gas regain speed, transmission disengages, engines revs, transmission down shifts to 1st gear and then attempting to "find" the correct gear. This has happened multiple times and a few of those times has left us susceptible to being struck by another vehicle due to no engine power to the power train to move the vehicle.

I have had issues with the 10 speed transmission on my Expedition. I looked up my year model and type of transmission and there is a NHTSA recall on select model year transmissions within my year range. My vehicle is doing the same thing that is stated in the recall. I spoke to a transmission shop and they are the ones that informed me of the transmission issues and recalls. I reached out to my local Ford dealership and they looked up my vehicle and informed me that my vehicle was not affected. I said it seemed to be doing the exact same thing listed. He said if its not on the list, we won't cover the repair. What needs to happen to have my transmission repaired under the recall?

NHTSA ODI 11736876

Was traveling on the roadway when my vehicle suddenly lost its ability to change gears. I had to put the transmission into manual mode to be able to pull to the side of the roadway and stop. The vehicle was towed to the repair facility where I was informed the transmission needed to be replaced. I was almost struck from behind by a motorist due to not being able to continue forward. I was informed this is a common defect in the transmission and the cost to replace the transmission is approximately $9000. Due to the low mileage on the vehicle, this is unacceptable and a safety risk.

NHTSA ODI 11736625

The 10r80 transmission went out in it after 80k miles. It would get "stuck" in gears and not want to shift. The lack of shifting would cause the vehicle to stall while driving. Ford was able to reproduce the issue and the transmission is getting replaced by Ford through our extended warranty company. There was a clunking noise when driving prior to the transmission having shifting issues. No, there were not any warning lights when this was happening.

NHTSA ODI 11733252

The 10r80 transmission of this vehicle failed resulting in erratic shifting, slowing and stopping of the vehicle in traffic, having to pull over in the middle of traffic. Rapid acceleration and deceleration resulting in jolting the people in the vehicle and abrupt speed changes. This has been confirmed by a private mechanic and a rebuilt transmission purchased from local Ford dealership. The broken transmission will be returned to Ford as the core is required to be returned for deposit refund. There were no warning lights or indications of failure other than shifting issues.

NHTSA ODI 11731514

Transmission harsh shifting. Common problem with ford on the 10r80. Was told from ford need new transmission

NHTSA ODI 11731415

Most mornings when I shift the vehicle from Park to Drive the transmission slams into gear and it feels like the vehicle just hit a wall. Also when shifting from 4th through 8th gear the transmission shudders through the shift sequence and sometimes it completely cuts out, total loss of power and have to coast to a stop on the side of the highway. This happens all the time.

NHTSA ODI 11730388

Faulty CDF Clutch Drum. The vehicle failed to shift properly while driving in mountains which could have lead to a runaway. Problem has been identified by my dealer and is a known issue with 2017-2023 Ford Expedtions. Vehicle inspected my FoMoCo mechanic and found issue with drum. No warnings or prompts before issue occurred.

NHTSA ODI 11729922

The cdf drum in the 10R80 transmission in 2021 Ford Expedition has failed causing inability to accelerate or decrease speech reliably. For safety during interstate driving, there is a indisputable need for quick and reliable increases and decreases in speed. Being able to clear an intersection quickly is important not only for the driver's safety but the safety of others in an intersection. Dealership has confirmed the problem. Ford released a TSB that has been around since 2023 regarding how this part fails and needs to be repaired. There were no warning lights or messages about the problem. The vehicle was purchased used at only 60,000 miles and dealership made no indication that transmissions had been an issue and could be a safety issue going forward.

NHTSA ODI 11729507

The component of the system that failed was an internal failure in the CDF drum in transmission. This resulted in failure to accelerate up to appropriate speeds and lurching of the vehicle when shifting gears. This put the safety of others and self at risk as the vehicle was unable to get up to speed on the road resulting in dangerous conditions that could lead to accidents due to the inability to reach posted speed limits. The vehicle and the components were inspected by a Ford dealership. No warning lights were observed to indicate that a problem existed.

NHTSA ODI 11708354

During highway operation, vehicle transmission makes very loud and angry sound and then loses ability to move , almost caused us to get hit at an intersection. Vehicle often jumps violently when shifting to reverse, and often loses propulsion when going uphill and shifting. No issues have been identified by mechanics but I have found several forums on line with drivers reporting similar occurrences. This is very dangerous and if not addressed will result in loss of life. We purchased this vehicle certified by the dealer with 92000 miles on it and it began doing this less than a week after purchase. We took it in for recall work and reported it and they said nothing was wrong with it. Manufacturer failure to rectify this very common problem is going to cause may citizens to be injured or killed.

NHTSA ODI 11705760

The contact owns a 2021 Ford Expedition. The contact stated that while driving at 45 MPH, the engine overheated. The message “Drive Mode Inoperable” was displayed. The contact pulled over for 20 minutes, and the vehicle was restarted. The vehicle was towed to the local dealer, who confirmed that parts were on back order for NHTSA Campaign Number: 22V346000 (Engine). The vehicle was diagnosed, and it was determined that the failure was due to the transmission. The vehicle was not repaired. The manufacturer was contacted and opened a case. The failure mileage was approximately 99,130.

Have had jerky shifts and hard down shifts while driving 2021 Ford Expedition. Told dealership and was told it was normal. Then went in for oil change told the dealership about lose of power while shifting and hard shifts they advised to have transmission fluid changed. Not even 3 weeks later while pulling out onto a busy road my vehicles engine revved very high but the transmission never engaged past 2nd gear. I was almost hit by a car coming at me on the 2 lane road. After letting off the gas and then reapplying gas the transmission engaged. I drove to the dealership. Today they informed me that the transmission has multiple failures at the shift point between 1-2 and 7-8 along with hard down shifts between 4 and 3 gears. Was informed that the transmission would need to be replaced. I never got any error or warning codes that anything was wrong. I told the dealership that I felt unsafe driving the vehicle due to the transmission. The first instance happened less than a month ago. My vehicle is at the shop now waiting to have a replacement at my expense when Ford knew what the transmission is like.

NHTSA ODI 11702802

While attempting to pass a slower moving vehicle and changing from the right lane to left, I attempted to accelerate past the vehicle when the check manual light appeared on the vehicle display dashboard and I lost all power. I had no acceleration and no power from the gas pedal, after gliding past the slower vehicle and completely taking my foot off the gas pedal, the truck reset itself and power came back to the vehicle and was able to accelerate again, as if nothing happened.

NHTSA ODI 11702381

Vehicle stalls out upon driving when trying to accelerate. Has popped up error which states to check fuel pump.

Nn 9/15/2025 While the car was running but parked, we began to smell burnt plastic/electrical. Upon trying to shut off the vehicle several service lamps came on advising to go immediately to a service center and that there was a powertrain issue. Vehicle would also not shut off. Upon arrival at dealership they diagnosed that the battery box had corroded and would need replaced under the 1time battery Junction box replacement campaign (22N19). Upon repair they discovered that the wiring harness was badly melted and would need replace part [XXX] . The problem lies here. This part is backordered with no date for availability. Ford refuses to acknowledge this as a problem, and will not help with rental or loaner assistance, as that repair shouldn't take more then a few hours to complete.
