2021 Ford Expedition Power Train

What component or system failed or malfunctioned, and is it available for inspection upon request? The transmission slams down into gear from 9th to 8th gear. It also slams in stop and go traffic from 4-5, 5-6. It is available for inspection. How was your safety or the safety of others put at risk? The transmission jerks hard enough to move you in your seat and could cause accidental breaking or acceleration. In stop and go traffic it could cause you to rear-end someone because it lags shifting. Has the problem been reproduced or confirmed by a dealer or independent service center? Yes. Has the vehicle or component been inspected by the manufacturer, police, insurance representatives or others? It has been back to the dealer 4 times for this issue. Were there any warning lamps, messages or other symptoms of the problem prior to the failure, and when did they first appear? No, there are not warning messages. It has done this since 17,000 miles.

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.

The vehicle was taken to the dealer where an unknown part was replaced in the transmission. The contact stated that the failure persisted and the vehicle would hesitate while depressing the accelerator pedal. The contact stated that no warning lights were illuminated. The contact stated that the vehicle was taken back to the dealer where the failure was unable to be diagnosed as no failure codes were found. The dealer was unable to duplicate the failure. The vehicle was not repaired. The manufacturer was made aware of the failure and a case was opened. The approximate failure mileage was 13,000.

Went to accelerate on on ramp and vehicle was not able to accelerate.

The vehicle transmission has failed, potentially do to towing (the vehicle is supposed to be towable) I bought the vehicle to be able to tow behind our RV. We took a trip last July from Thousand Oaks, CA up through 5 national parks all of the way to Glacier National Park in Montana. The vehicle appeared to tow normally, i never had a problem getting the vehicle to indicate the Tow Mode was active. In January of this year (almost 6 months after the trip), my transmission made a clunking sound, and started to perform poorly. We called the dealership immediately to have it looked at. The dealer said i must have towed it incorrectly and therefore it won't be covered under warranty. I had a second opinion which did not agree with Ford's assessment. Ford had an engineer look at the transmission, and the engineer reiterated it must have been towed incorrectly. I asked how they assessed if the vehicle could have come out of tow mode through some error and the refused to answer or provide any additional details. They would only say that the transmission appears damaged from improper towing. I do not disagree with them that the vehicle could have been damaged during towing, what i disagree with is the assertion it was not properly in Tow Mode. I followed the process in the handbook, had a affirmation it was in tow mode every time before we moved the vehicle. When teh vehicle is attached to our RV there are two option. Park - when we are stationary for a period of time, or Tow Mode when moving. There are no other options. Ford said they have reported this incident already, i would like confirmation if possible to make sure. I would also like to know if other similar incidents have been reported.

The contact owns a 2021 Ford Expedition. The contact stated that while driving at an undisclosed speed, the vehicle briefly lost motive power with several unknown warning lights illuminated. The vehicle was able to accelerate shortly after losing motive power. Additionally, the transmission experienced rough shifting into the intended gear. The vehicle was taken to the dealer, where it was diagnosed with transmission valve body failure and the transmission valve body was replaced. The failure recurred while the contact’s wife was driving with the vehicle jerking. The vehicle was taken back to the dealer, and the dealer reset the transmission. The manufacturer was not made aware of the failure. The failure mileage was 13,722. The contact has stated that the vehicle's issues has caused multiple occurrences that could have resulted in an accident.

While accelerating on a busy tollway, the automatic transmission got stuck in 6th gear. The car then began to slow down, and the gear display went blank. This put my safety and the safety of others at risk, as it happened in the left lane of a busy, high-speed tollway. The local dealership refused to help--even though the car is within warranty--as they did not believe the issue was replicable. However, the car had a similar problem on a lower-speed roadway just a few weeks prior. In both incidents, the transmission became stuck in one gear, the gear display on the dashboard went blank, and the car began to decelerate.
