2020 FORD F-150 Complaints

f150 EQUIPED WITH 4r80 10 SPEED TRANSMISSION. Starting several months ago, the vehicle started experiencing up shifts with hesitation during upshift, typically the mid gears. Starting from a stop, the shift from 1st to 3rd is very harsh and stutters. Condition has progressively gotten worse. While upshifting, I am now experiencing more exaggerated pausing/delays during mid gear upshifts. While entering a freeway, accelerated to merge with traffic and the transmission downshifted and there was an approximately 2 second delay in the shift which caused the vehicle to bog down substantially, nearly causing a following vehicle to impact my vehicle.

My gears shift hard when slowing down or when letting go of the gas pedal. The infotainment center blacks out. I took it in to Ford Dealership and was told the transmission needed to be replaced. I don’t drive fast nor abuse my truck. I don’t use my truck for construction; I simply drive to work and home. I have 67K miles and bought the truck in 2020, brand new. It’s very concerning that at 67K the transmission needs replacement. The cost for replacing the transmission is $8,000.00 dollars.

The contact stated that he had taken the vehicle to a dealer and was advised that the failure could not be duplicated. The vehicle was not repaired. Additionally, the check engine warning light was illuminated while the transmission was downshifting. The contact had taken the vehicle to the same dealer who diagnosed the vehicle and determined that the long block and the transmission needed to be replaced. The vehicle was repaired. The manufacturer was informed of the failure but advised the contact that the vehicle was over the mileage for the warranty and not covered. The failure mileage was approximately 72,000.

Transmission has hard shifts between 2-3 and 4-5. Transmission occasionally has unexpected hard down shifts. Truck has done it since purchase and has progressively gotten worse.

On the afternoon of [XXX], my son and his fiancé were driving home from college (Lamar University) when my sons 2020 Ford F-150 suddenly downshifted from 10th gear to 1st gear. This sudden unexpected downshift through them both violently forward in the truck and almost caused them to be rear ended by an 18-Wheeler. They immediately pulled off to the side of the Interstate ([XXX]) to gather their thoughts and inspect the truck. My son notified me of what had just happened and that he received a service engine warning on the trucks instrument cluster along with a notification on his cell phone of a Powertrain Malfunction. I suggested he try turning the truck off and restarting it to see if it would resolve the issue. He resumed driving home and experienced the same unexpected sudden down shifting from 10th gear to 1st gear multiple times as they continued their drive home. Fortunately, he was able to limp his truck back into town and immediately took it to Cook Ford in Texas City where we had purchased the truck. I met them at the dealership and my son reported the problem they had experienced on their drive home to the Cook Ford Service person and we left the truck with them to be diagnosed. On Wednesday March 26th 2025, Cook Ford called to inform my son and informed him that he needed a new transmission and that both his catalytic converters needed to be replaced for a cost of approximately $11,500. He asked them if these items were covered under warranty and they acknowledged an error in their quote and that the catalytic converters would be covered, but not the transmission. During the conversation the Ford Service person did acknowledge knowing of issues with the 10 speed transmission (10R80) but said there were no current recalls, nor were there any Ford Customer Satisfaction Programs for the trucks transmission. We are now waiting for a response back from Cook Ford with an updated and formal breakdown of costs for the trucks needed repairs. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION A

This truck when shifting from 4th to 5th will snap your neck! sometimes it just slips in gear., when I back up ity will stop like its in neutral and then bang into gear. sometimes you pull out on the road and it will not go just sit in neutral then bank in gear and take off. This is totally unsafe with this 10 speed trans.
