Ford Expedition loss of power problems

Filed Oct 29, 2026 · Engine, Transmission · FL

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)

I was making a right hand turn and had loss of power and a clunk sound. I also experienced loss of power between 65-75 mph on the freeway. I ran a forscan report and it's pointing to the transmission even though the fluid and a tcm update has been performed. There is about 40k miles on the fluid.

Since early in purchasing our 2019 Ford Expedition, we were getting powertrain warnings (pictures attached from August 2019). We took the vehicle in to have it diagnosed but the dealer said there were no codes and nothing they could do to troubleshoot. Fast forward to after the warranty expires the car starts behaving erratically when it's changing gears, especially when downshifting. On more than one occasion when towing our boat, I would press on the gas to pass a semi truck and there would be a loud CLUNK that you could feel and then the motor would simply rev indefinitely as if the transmission had switched to neutral. It's very dangerous losing power on a freeway with traffic including semi trucks and towing a boat. It got to the point where it would be very jerky just driving, particularly (it seemed to me) when the car had been sitting. This has happened several times. I did some research and found there were 4 TSB's for this issue and is an issue for all of the Ford 10 speed transmissions for Expedition, F150 and even the Mustang. I reached out to the dealer with these TSB's and they diagnosed that our car did have this troubled transmission and we did have the faulty parts. The dealer has charged us $7,575.35 to 'Repair" this. I think this warrants a recall due to the faulty parts in the transmission. It's very dangerous losing power and torque in a vehicle particularly when towing. Please review the attached pictures (notice the milage from our initial indications there was trouble with the powertrain). This got progressively worse just prior to us taking the car to the dealer. I would say it was at it's worst from December 2024 through our repair at the delaer in June 2026, but there were other random occurences prior to that and of course the very begining as seen in the attached photos.

“This vehicle is experiencing an intermittent complete loss of power while being operated. It has now happened multiple times, including twice within one week after the vehicle was in your shop for 30 days. I have children in this vehicle. I am requesting that this be treated as a safety-related defect and escalated to Ford engineering

In 2025, our 2020 Ford Expedition had harsh, erratic shifting, then would lurch during shifts or lose power. Ford service replaced the valve body plate and reset the transmission software. This did not fix the harsh shifting; it only cleared the warning lights when the harsh shifting occurred. Now in 2026, shifting and gear sticking have continued to get worse, and now Ford says we need a new transmission, but it is now conveniently out of warranty. This is an issue the dealership was not transparent with us about; it is a safety issue when driving, and now the costs are intended to be completely out of pocket for us.

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.

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.

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.

Vehicle has roughly 64,000 miles on it. As we were actively driving, vehicle suddenly lost power and completely shut off. This was a sudden stall. Vehicle would not crank back up but starter would engage. Upon scanning the trouble codes, multiple codes came up in regard to the fuel pump issue that is currently under investigation. (P008A, P00C6, P0304) This issue poses a serious risk as while actively driving, could cause an accident and should be an active recall for this year make and model.

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.
