2021 Ford Expedition Vehicle speed control Problems

“For the 3rd time attempting to pass other vehicles our transmission revved up to almost 5000 rpms and would not shift after making a huge clunking sound into an obviously to low gear. We had no power and the vehicle would not accelerate. I do have a video after the clunk sound but can't upload it.”

“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. …”

“I am filing this complaint because I truly believe this transmission issue is a safety problem. I was driving my 2021 Ford Expedition and was merging onto a busy highway when I pressed the gas to get up to traffic speed. Instead of accelerating, the engine revved but the transmission would not shift. It felt like the vehicle was stuck between gears or in neutral. My SUV would not accelerate when I needed it to, and I remember thinking, “This is how someone gets hit.” As a mom, it was terrifying. I depend on my vehicle to safely get my family where we need to go. …”

“When driving down the road and it does not matter what speed I am going, is when this issue is happening to most. I will be driving and out of the blue the tachometer will just drop to zero (0) and I lose all power and the vehicle starts shaking vigorously back and forth until it decides what gear the transmission wants to be in. It is doing this every single day, and it almost made me wrecked the other day. I do not even have 70,000 miles and it will be three years old in April 2024. I have called Ford and reported the issue as well. …”

“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.”
