2021 Ford Expedition: grinding or squealing brakes

Filed Jul 15, 2026 · Acceleration, Transmission · MI

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,

Mid shift between 5th and 6th gear it sounded like marbles in my engine(grinding) so I let off the gas. It then switched down to 1st gear shuttered and slowed down and then shifted back to 6th. Was lucky no one was behind me or I would have been rear ended. Then going up my driveway same day. It disengaged(stopped) part way up my driveway. Wouldn’t go into gear and wouldn’t move. I had to shut it off put it in park and start it again. Then when I shifted back to drive it made some clunking noises and didn’t move until I put it in reverse. I rolled down the hill then was able to shift into drive and go up the driveway. I no longer trust it. So it’s been parked ever since.

Transmission Failure Rough or jerky shifting: This occurs when accelerating or decelerating, and even when shifting between gears. Delayed gear engagement: Shifting from park to drive or reverse can be slow, or the vehicle may lunge into gear. Transmission slipping: The transmission slips between gears, causing a loss of power or acceleration. It can also cause a violent grinding/shaking between shifting gearshifts resulting in loss of acceleration.

On numerous occasions, when traveling at speeds 50mph and over, the vehicle failed to further accelerate when the gas pedal was engaged. This caused the rpm's to rev up to 7 and the vehicle to slow down. Our safety was at risk because the vehicle was unresponsive to acceleration for at least 20-30 seconds making it impossible to avoid or get away from something dangerous. On one occasion, the vehicle made an alarming grinding sound. I have not yet taken the vehicle to a service center for inspection of this problem. There were not any warning lamps, messages, etc prior to the failure.

Front differential failed. I was driving to the mountains and when I reached snow level it was about 38 degrees F and I slowed to less than 20 mph and switched to 4A. Within a few moments I heard and felt a grinding sound from the front. I have used 4WD several times over the year or so I've had the vehicle and have never heard this noise before. I thought it was the hubs not engaging completely and so I switched it back to 2wd and while the noise was less it continued. I switched back to 4wd and I confirmed that 4wd was working but the noise persisted. I bought this vehicle specfically for its 4wd and my family's life depends on it working when we are up in the Sierras where it snows 2-3 inches per hour. When we returned I immediately took the vehicle to the dealer who informed me that it was the front differential that failed and parts are on back order. I am still waiting two weeks later. They said this is not common but why are parts on back order if it is not so common?

Transmission routinely goes out of gear making a weird grinding sound, loses power and decelerates without warning. This has occurred at speeds from 10 mph to 70 mph. Neighborhood streets, roads, highways, and interstates. Very dangerous situation. The vehicle has approximately 22000 miles and this has occurred 20 times at minimum. I have been extremely lucky that this has not caused an accident or crash. The vehicle was purchased new from the dealership. I informed the dealer after numerous occurrences. The dealer inspected the vehicle in August. They said the vehicle computer time stamped the issue but they could determine the issues??? The same transmission problem has occurred 5 times since August.
