2021 Ford Expedition: check engine light

Filed Sep 8, 2026 · Transmission · OH

While trying to pull out of a residential neighborhood onto a state highway (45 mph speed limit), the vehicle refused to accelerate. The transmission couldn't engage into gear and the vehicle struggled to gain momentum. After letting off of the accelerator pedal, and then applying the accelerator again, the transmission was able to engage, and the car began to accelerate. No check engine light or other indication of a problem. The Ford dealer told us that the CDF drum of the transmission needed to be replaced. It is a known defect due to poor engineering design. This is very common problem in 2020 and 2021 Expeditions and F150 vehicle.

My catalytic converter of my 2021 expedition is going out. We had a 2019 Ford Expedition Texas Edition and I had the same issue. We purchased our current expedition in April of 2023. This spring the converter was signaled with the check engine light and since then my vehicle has had issues with acceleration, it consumes gas at an extremely high rate and my engine works harder over time. My concern is that my vehicle will have an engine malfunction or put me into bankruptcy by the amount of gas it consumes per trip. I found that many other expeditions from the years 2018-2022 have similar issues to mine, in fact one of my friends in town had the same issue. I reported my issue to Ford and they said they would not repair. My vehicle has less than 80k miles on it.

We just purchased this vehicle and started to notice a hard down shift when slowing down from 6th gear. I drove it Saturday January 21st and when I shifted the vehicle into reverse to back into a parking space it threw the transmission into a fault and had no reverse. Still drove forward. Took the vehicle in for service on 1/25/23. They ordered parts to fix the harsh shift. No comment on the reverse issue. Picked up vehicle evening of 1/25/23. Drove from dealership to gas station close to home, about 15 miles. Shut vehicle off to fuel. When I restarted the vehicle it kept pushing forward against trans pawl and then rolling back repeatedly. After it did this 10 times or so I put the vehicle in Nuetral and it proceeded to drive forward for 20-30 feet uphill. After 20-30 feet of driving forward the wrench light turned on and the vehicle stopped driving forward and rolled backwards down the hill as it should have. After this the vehicle had forward gears but no reverse gears. Wrench light and CEL light both illuminated when driving home from gas station. Will have dealership tow back 1/26/23 due to safety issue of vehicle driving forward while not in gear.
