Power Train Problems of Ford Expedition - part 1

While driving my 2017 Ford Expedition limited 4wd at approximately 45 mph, the speedometer suddenly dropped to 0 mph even though the vehicle was still moving. At the same time, the wrench warning light illuminated, and the transmission became stuck in third gear. The transmission would no longer shift normally, including when slowing down and accelerating again. I was able to safely pull over, shut off the engine, and restart the vehicle. After restarting, the speedometer and transmission returned to normal operation, and the warning light disappeared. This is approximately the third time this same failure has occurred within the past 15,000 miles. The vehicle has approximately 200,000 miles and previously displayed diagnostic trouble code p0720, indicating an output shaft speed sensor circuit malfunction. These symptoms appear consistent with a possible failure of the transmission’s molded lead frame or integrated output shaft speed sensor in the 6r80 automatic transmission. I am concerned that this intermittent failure could result in an unexpected transmission downshift, sudden deceleration, or loss of normal transmission operation while driving at highway speeds, increasing the risk of a collision. I understand similar transmission lead-frame failures have been documented in other Ford vehicles equipped with the 6r80 transmission. I am requesting that NHTSA investigate whether the 2017 Ford Expedition is affected by the same potential safety defect.

The contact owns a 2020 Ford Expedition. The contact stated that while driving at 60 mph, attempting to accelerate to 65 mph, the vehicle locked up on the freeway. The vehicle jolted like someone hit the rear of the vehicle. Ford customer relations was contacted by phone. The vehicle was taken to a mechanic who scanned the vehicle and determined the failure was related to p07e6 and u1a00. The contact sustained bruises on her chest and shoulder from the seat belt. The local dealer was contacted. The contact called another local dealer  star Ford service : 1101 s brand blvd, glendale, CA 91204, and the dealer determined and advised the recall remedy was not available for NHTSA campaign number: 26v402000 (power train). The failure mileage was unknown.

2020 Ford Expedition 10 speed transmission ?numerous times while driving in the [xxx]/[xxx] area we were attempting to merge into traffic. While trying to merge, we pressed the gas in order to merge into traffic and the powertrain seized up with a total loss of power (it was basically like it went into neutral) and the rpm’s jumped to 6000-7000 rpm. When we let off the gas, the transmission finally slammed back into gear with a loud clunk and it finally re-engaged. This shifting situation has happened several times over the past 8-12 months. Just recently (xxx) it happened three times in that day. This is an extremely dangerous issue. The last incident there was had a cement truck coming up on and I could have been run over. I’ve have had the car in the dealership approximately 3-4 times for this issue and each time they state they cannot replicate the problem. If it happens three times to me in one day and Ford can’t replicate the issue???I have had three other family and/or friends with me when this issue has happened so it’s quite real issue. Frankly. I feel like Ford just don’t want to pay the expense to fix the problem. Information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

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.

While driving at highway speeds, specifically during sudden acceleration and lane-change maneuvers, the vehicle experiences a severe dynamic mechanical binding event. The transmission briefly forces a sudden "halt" or engine-braking downshift, causing the vehicle to unexpectedly slow down in active traffic before entering a temporary limp mode. This sudden loss of propulsion and unexpected deceleration creates an immediate rear-end collision hazard on the highway. This happened to my wife while merging onto a highway almost causing an accident. Diagnostic and mechanical verification: the vehicle was taken to an authorized Ford dealership for evaluation. The dealership officially scanned, verified, and documented diagnostic trouble code p0786 (shift timing solenoid "a" range/performance). Following an advanced diagnostic review, the certified Ford technician officially diagnosed a failed transmission park solenoid (parking pawl solenoid). Direct relation to active safety recall: the component failure (park solenoid), diagnostic code (p0786), and severe dynamic highway-speed binding symptoms are identical to the safety defects outlined in Ford safety recall 26s48 (NHTSA campaign 26v402). Reason for filing / manufacturer action: despite an authorized Ford dealership verifying the exact failure mechanism of this active federal safety recall, Ford corporate are currently refusing to cover 100% of the repair costs. They state that my specific VIN has not yet been "activated" in their database due to Ford’s phased tranche rollout schedule extending through 2027. I am being forced to pay out-of-pocket for an active, dealer-verified, federally recognized safety hazard. We cannot drive the vehicle with this significant safety risk. I am paying mostly out of pocket to cover the repair.

When the vehicle is in motion, the transmission shifts very hard (with a loud audible "bang") between gears 4 and 5, and intermittently power is lost to the wheels (again, while the vehicle is in motion, you depress the accelerator, the engine revs up, but the vehicle does not accelerate). Once you brake and come to a stop, the vehicle accelerates properly again.

My car is a 2020 Ford Expedition max with under 39,000 miles. A major transmission issue was just discovered while getting the 40,000 mile service. I believe it is the same issue as described under recall 26s48. The car suddenly shifted into neutral while driving on the freeway two separate times. The car is currently at the dealership, they got a p07e code, but did not experience the issue themselves.

While accelerating from a stop after a traffic light, the transmission briefly shifted into neutral on its own, causing a momentary loss of motive power. The vehicle recovered on its own without stopping. This has happened once so far. The transmission also slips rarely at other times. The dealer has not inspected the vehicle yet. This vehicle has an open NHTSA recall, campaign 26v402 (Ford 26s48), for the transmission potentially engaging park while the vehicle is moving.

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!.

Vehicle has 84,000 miles at it. It started to jerk when putting it into a gear. I thought it was due to the colder mornings no. I was taking the kids to school and it was skipping gears. I was very leary of driving but had no choice. It would not get up to speed the rpms was suffering. I stopped at a parts store to run the code after the warning popped up. When leaving because I was 30 mins from home it jerked when I placed into gear, I was scared to pull onto the 4 lane due to not being able to get up to speed and being in a high traffice area. Very unsafe. Now the vehicle is at the dealership needing a $7,000 transmission and Ford will not assist. I am still financing it through a dealer and there is no goodwill from Ford. This is known issue that they documented.

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 2018 Ford Expedition with the 3. 5l ecoboost engine has developed a pronounced rattling/knocking noise at startup. This appears consistent with the well documented cam phaser/vct problem affecting this engine family. At approximately 118,212 miles, an independent firestone complete auto care inspected the vehicle and recommended major timing system repairs. Their estimate calls for replacement of the timing chain components and variable timing sprockets/cam phasers, with a total recommended repair cost of $5,232. 13. 220782orderrevisions. Pdf the concern is not simply the noise. The cam phasers and timing system control critical valve timing. If these components continue to deteriorate, there is a risk of improper engine timing, severe drivability problems, loss of power, stalling, or significant internal engine damage. A failure while traveling at highway speeds or in traffic could create a serious safety hazard for the occupants and surrounding motorists. There have not yet been warning lights or dashboard messages associated with the condition. The primary symptom has been the recurring startup rattle/knock, which has now been confirmed by an independent repair facility as requiring substantial timing system repair. The vehicle remains available for inspection. This has been an ongoing issue for the last few months but was first diagnosed on September 12, 2026 during a repair for another unrelated issue. I am especially concerned because this is not an isolated or unusual type of failure on the 3. 5l ecoboost. Ford has previously recognized cam phaser/vct startup noise on these engines through service guidance. A known timing-related defect requiring more than $5,000 in repairs, with the potential to progress into engine damage or loss of engine performance, represents a significant reliability and potential safety concern.

The contact owns a 2019 Ford Expedition. The contact stated that while driving at an undisclosed speed, the vehicle failed to accelerate as needed, with the powertrain warning light illuminated. The contact pulled over to the side of the road, shifted to park, and restarted the vehicle, and the vehicle temporarily drove normally. The contact received notification of NHTSA campaign number: 26v402000 (power train); however, the part to do the recall repair was not yet available. The local dealer was contacted. The contact stated that the manufacturer had exceeded a reasonable amount of time for the recall repair. The manufacturer was made aware of the issue. The vehicle was not repaired.

I was traveling on the interstate and went to accelerate to pass a vehicle. My car displayed system fault codes and made a clicking noise and dropped to neutral while my rpms stayed high. I lost acceleration and had to swerve to avoid a collision. The engine then had a loud clank and jerked into gear. Once I had pulled off enough I turned the car off and on again and resumed driving. This has happened multiple times. Each time when I have contacted Ford they say it’s a known issue with the make of the clutch drum and realized the issue after the 2022 year and changed the way it was made. However they stated it would cost me over $6500 to repair mine. They do not accept fault only state it is a known issue. When my car goes from 65 to 39 in a span of a few seconds it is a huge safety issue.

My 2021 Ford Expedition max XLT with the 10r80 automatic transmission has experienced repeated momentary “neutral-out” events while driving. The transmission/park-system components are available for inspection upon request. The most serious incident occurred in September 2026 while I was driving at highway speed near charlottesville, virginia, with six children in the vehicle. I was not towing or placing the vehicle under unusual load. The vehicle suddenly behaved as though the transmission had shifted into neutral, the rpm/engagement became abnormal, I heard loud thumping, saw smoke or fumes from the rear of the vehicle, and observed a transmission temperature of 261°f. The vehicle later re-engaged. This created a serious safety concern because I temporarily lost normal propulsion/acceleration capability while traveling at highway speed with other traffic. This problem has previously been confirmed by my Ford dealer. In February 2026, I reported that the vehicle would “neutral out and rev up,” hesitate for several seconds, and then go back into gear. The dealer documented that no diagnostic codes were stored but followed Ford TSB 23-2249. During diagnosis, the dealer found physical wear/damage involving the transmission parking pawl area, rear output shaft, and cam. The transmission was removed and disassembled and multiple park-system components were replaced. The neutral-out condition returned after that repair. In July 2026, I again reported that the vehicle would intermittently neutral out for several seconds and then re-engage. The dealer was unable to reproduce it and again found no diagnostic trouble codes. In September 2026, after the 261°f highway incident described above, the dealer again scanned the vehicle and found no codes and was unable to reproduce the condition during approximately 100 miles of testing. There have been no transmission warning lamps, transmission messages, or.

The failure mileage was approximately 60,000.

The car has started uneven acceleration and lurching when driving. A local Ford dealer service department has recognized this as a known problem requiring the replacement of the transmission cd drum. Uneven driving creates a risk when driving.

The car has recalls since 2024? some are serious safety issues if in an accident. Way too long for a remedy from Ford. 2019 Ford Expedition 2019 Ford Expedition VIN: [xxx] recall data refreshed on xxx 4unrepaired recalls associated with this VIN Feb 09, 2024 information redacted pursuant to the freedom of information act (foia), 5 u.

Transmission shifting very hard and lost forward momentum while on highway nearly causing accident. The resulting tow and repars totaled close to $5000. 00.

The car will lose power when trying to accelerate on the highway. The car’s transmission will completely shift out of a high gear while traveling 50+ mph at a time when you are trying to accelerate onto the highway or speed up to avoid another vehicle. The car’s transmission will shift to first and slow way down and you cannot regain power or speed for several seconds. This has happened multiple times over the last several months, sometimes multiple times a day.

When accelerating, if you push on the gas hard the car will shift into neutral/park and then shift back into gear. It doesn't matter if this happens at 20 mph or 75 mph. It is extremely unsafe. This shift fault code p07e6 is the code that populates. It is directly correlated with the recall 26s48/26v402. Ford won't even glance at it to consider it a part of the recall because " there is no fix for the recall yet " . This recall has directly damaged the transmission in my vehicle & other peoples vehicles. I have requested a remedy as my vehicle is no longer safe to drive on the highway due to the shift issue and I am met with we won't be able to address it until the recall fix is out. I have requested a loaner while we wait for the recall fix, which isn't going to be ready till 5/2027. Ford needs to consider the transmission damage this recall has caused on vehicles, the safety issues behind that damage, and they need to make it right.

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.

For the past month I have started noticing my Ford Expedition changing abruptly between certain gears. The problem progressively got more noticeable until last week while driving my Ford Expedition on the highway it lost power unexpectedly, feeling like it was about to stall while driving 65 mph and on the third lane while the car randomly downshifted from the 10th speed to the 6th. The person behind me almost rear ended me in the process. Just a couple of days after that (while waiting for my appointment with the dealership), I encountered another close call while entering a roundabout. The vehicle again felt like it was stalling, causing me to lose momentum in the middle of the intersection and this time almost getting hit on the side with both my young kids in the car. This is especially alarming because I am clearly not the only one to run into this problem yet no recall have been made or at least not on all the models that are affected. This issue is related to a known defect in the 10r80 transmission used in this vehicle, which I understand is widely reported among other owners of this model. I have an active repair and goodwill claim open with Ford regarding this transmission issue. I'm filing this complaint to document the safety risk this defect poses, particularly the loss of power in live traffic situations, and to ensure it's on record with NHTSA.

The contact owns a 2020 Ford Expedition. The contact stated that while driving at an undisclosed speed, the transmission attempted to shift into park but downshifted from third gear into first gear instead. No warning lights illuminated. The contact received notification for NHTSA campaign number: 26v402000 (power train); however, the parts to complete the recall repair were not available. The contact stated that the failure was persistent and once occurred while the contact's family occupied the vehicle, creating a safety hazard and rendering their only vehicle unsafe to drive. The dealer was notified of the failure, but no assistance was provided. The vehicle was not diagnosed or repaired. The manufacturer was notified of the failure, and a case was filed. The failure mileage was approximately 142,696.

My 2019 Ford Expedition max 4wd has approximately 120,000 miles. Intermittently the engine rpm increases but the vehicle does not accelerate as expected when I press on the accelerator. The transmission does not appear to be shifting between 5th and 6th gears. This creates a safety concern because the vehicle does not always accelerate when expected, specifically when entering or merging with highway traffic. I took the vehicle to a Ford dealership on August 24, 2026. I described the symptoms to the service representative. The representative told me that this transmission has a known issue involving the clutch shaft/sleeve and indicated that repair would require significant transmission work. I declined the $200 diagnostic service because I do not intend to authorize the approximately $9,000+ repair. The vehicle has not been formally diagnosed.

My Ford Expedition’s 10-speed automatic transmission experienced repeated slipping and sudden loss of propulsion. While accelerating from a stop and entering the highway, typically around 15–20 mph, the engine would suddenly rev but the vehicle would stop accelerating, as if the transmission had shifted into neutral. I had to release the accelerator for several seconds and slowly reapply throttle before the transmission would re-engage. This occurred repeatedly and created a serious safety hazard when pulling into or crossing traffic because the vehicle could begin accelerating normally and then unexpectedly lose propulsion with approaching traffic. The transmission also exhibited severe harsh/banging shifts during harder acceleration and produced a rattling noise while slipping until the accelerator was released. Cdf drum failure has been confirmed. The vehicle is currently at a reputable independent transmission repair facility undergoing a transmission rebuild due to the cdf failure. The transmission/components are available for inspection during the repair. There were no warning lights or messages that reliably warned of the impending loss of propulsion. This was not simply poor shift quality; the transmission defect caused an actual loss of propulsion while driving. Because this failure can leave a driver unable to accelerate while entering an intersection, pulling onto a highway, or merging into traffic, I believe the cdf failure presents a serious safety risk. I am requesting NHTSA investigate cdf-related transmission failures and determine whether a safety recall is warranted. TSB 23-2250.

The contact owns a 2018 Ford Expedition. While the contact's wife was driving at an undisclosed speed, the transmission independently shifted into park. The check engine warning light illuminated, and the transmission brake error message was displayed. The vehicle was turned off. The vehicle was restarted; however, while driving at an undisclosed speed, the failure reoccurred. The failure was a persistent failure. The dealer was made aware of the failure but provided no assistance. The vehicle was not diagnosed or repaired by an independent mechanic or dealer. The contact referenced NHTSA campaign number: 26v402000 (power train); and the VIN was associated with the recall. The manufacturer was made aware of the failure but provided no assistance. The failure mileage was approximately 90,000.

The contact owns a 2020 Ford Expedition. The contact stated that while driving at an undisclosed speed, there was a delay in the transmission shifting gears. The vehicle was taken to the dealer for the transmission to be reprogrammed. The failure recurred, and the transmission was shifting roughly, and the vehicle lost automotive power while driving. The vehicle was taken back to the dealer, where it was diagnosed with a drum body failure, incorrect gear ratio, and metal shavings were found inside the transmission. The vehicle was not repaired. The manufacturer was not notified of the failure. The failure mileage was 122,600.

I have a 2020 Ford Expedition, , affected by NHTSA recall 26v402. The recalled condition has actually occurred on my vehicle. The vehicle failed to remain in park and moved in reverse with the driver's door open. It struck a brick mailbox, severely damaged the driver's door, and I was pulled/dragged by the vehicle while my children were inside. This is an actual safety incident involving unintended vehicle movement, property damage, and a potential bodily-injury event. " this just occurred and has not yet been inspected.

Vehicle regularly shifts harshly, and on multiple occasions has completely lost power/forward movement as if the transmission completely disconnected from the vehicle. The vehicle would then reengage with a harsh lurch. Almost rear-ended a few times with children in car. Ford dealer states transmission needs replacement, but Ford motor company refuses to financially assist with repair despite this seeming to be a manufacturer or engineering defect. Although I answered “no” to the question if there was a crash below, it was close.
