2021 Ford Expedition: sudden loss of power

Filed Oct 28, 2026 · Engine · AZ

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.

For the past three years I have complained about the transmission dropping out of gear. It happens most often if I'm towing a trailer. I seems to occur in spurts, happening a couple of times in a few days then not for some time. Very dangerous if you pull around to pass and suddenly you lose power. Originally the dealership said they could find nothing wrong. I have read recently that Ford is having trouble with their transmissions. At my latest service appointment, I restated my problem and was told I need a new transmission.

While stopped at a traffic light, my 2021 Ford Expedition began running rough. When the light changed and I accelerated through the intersection, the vehicle experienced a severe loss of engine power and barely made it through the intersection. After I pulled off the roadway and released the accelerator, the engine stalled. I was able to restart the engine once while applying approximately one-quarter throttle. It continued running rough and stalled again when I released the accelerator. The vehicle was taken to Robinson Brothers Ford/Lincoln in Baton Rouge, Louisiana. The Ford dealer documented the rough running, low power and stalling and diagnosed the "fuel pump inop." The dealer removed the fuel tank and replaced the fuel pump/sender assembly. The replacement part listed on the dealer invoice is Ford part JL1Z-9H307-G. Vehicle mileage was approximately 79,390. Several months before the complete failure, during very cold weather, I also experienced one brief incident of unusually low engine power shortly after starting the vehicle. I do not know whether that earlier incident was related. I am concerned that this failure may be related to the low-pressure fuel pump failure condition addressed by Ford Safety Recall 25S75 / the federal safety agency Recall 25V‑455, which includes certain 2022 Ford Expeditions. My 2021 Expedition is not currently included in that recall. The loss of power occurred while I was crossing an intersection and created a serious safety risk. I am submitting this complaint so the federal safety agency can evaluate this fuel pump failure along with failures involving other vehicles excluded from Recall 25V‑455.

Vehicles automatic transmission repeatedly looses its gear, often while accelerating. The transmission tries to shift down, but somehow ends up loosing engagement and will not re-engage. This lead to critical/dangerous situations on Highways due to the sudden loss of power.

On my expedition I started having issues with my transmission staying in gear while driving. I will be going up a hill and all of a sudden boom it starts down shifting or not accelerating at all. I had a few times when me and my wife will be driving, and we would be going through a intersection or a area where you don't want to slow down and then the transmission would forget which gear it would be in and lose all power. Keep in mind my expedition only has 83K miles and serviced regularly. $8,900 later it needs a new transmission. This is a huge safety problem that's being ignored.

I have a 2021 Ford Expedition Max that we purchased new. From the time we first purchased it, it has had an intermittent issue. During these times if I accelerate hard or try to give gas to go up a hill, it will occasionally act like it is losing power- like it drops into neutral and stops accelerating. If I do not let off of the gas immediately, it is followed by a loud metallic rattling/ grinding noise. If I release the accelerator, it recovers quickly and seems to “reset” and I’m able drive like normal. On a few occasions a brief warning has popped onto my dash but it goes away so quickly that I never know exactly what it said. It MAY have said something related to parking but I can’t recall what I’ve seen before it goes away. I’ve learned to adjust my driving, making as few hard accelerations as possible to avoid this. Sometimes they can’t be avoided. It becones scary when I’m trying to merge or have to make a quick turn to get into a break in traffic because when it happens at those times I’m not able to accelerate to avoid the oncoming traffic. It doesn’t do it every time but seems to do it more the more I’ve driven like longer trips and I believe it’s gotten more frequent over time despite my adjustments in driving. Last year a Ford dealership looked at it and we thought the recall they fixed might fix it but it did not. Now they’ve reproduced the issue and diagnosed DTC P07E6 referencing TSB 23-2249 and saying the transmission needs replaced. I am aware of the federal safety agency Recall 26V402 (Ford 26S48) involving similar vehicles with transmission/park system concerns. Although my VIN is not currently included, the similarities prompted me to submit this complaint in case my vehicle represents the same or a related safety issue. I don’t have the official diagnostic report yet as the dealership still has my vehicle but I’ll include a photo of my conversation with the dealership,

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

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.

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.

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.
