2020 FORD F-150 Complaints

Driving down the highway at 70mph the truck dropped from 10 gear to 1st gear while losing speed I tried to accelerate to maintain safe speed but did not have power. The car jerked back to 8th gear then back down to 1st gear. Eventually back up to 10th gear but not full power. I was able to pull to the side of the road and turn the car off. After turning the car back on, the yellow wrench symbol disappeared from the dash and I was able to drive. The transmission now skips gears and does not have full power when accelerating. It felt extremely unsafe going 70mph then suddenly being in 1st gear losing speed as other cars continue around me at highway speeds and my car is decelerating without me using the brakes. There were no prior indications of this fault, my car was even serviced at a Ford dealership 2 months ago.

When starting the vehicle, while the vehicle was in park, it acted like the vehicle was in drive and surged forward. This is unsafe and needs to be addressed by Ford.

The 10R80 transmission has harsh erratic shifting. The transmission will occasionally launch when downshifting into first gear when pulling into my driveway causing me to almost hit the front of my garage. The transmission also has harsh clunking when shifting gears and will clink and throw you forward when downshifting in traffic.

Transmission gear shifting isn’t smooth. This has been occurring for 50k miles. Often going into one low gear to the next will hear a “clunk” sound.

Transmission has hard shifting, skips 2nd gear and sometimes will downshift out of 10th gear.

As I was driving my truck down the highway at 60 miles an hour, it tried to downshift to first gear several times. During that same time it lost several gears in the transmission. Ford is now replacing the transmission which is going to cost me a significant amount since the vehicle is just barely out of warranty. The truck did not have any prior warning lights or codes. It was hesitating to shift between gears occasionally for the last few thousand miles. This was an unsafe situation because the tires could have locked up and caused me to slide off the road at a high rate of speed. The dealer called after the diagnostic and essentially said "there's no way around it, this truck needs a whole new transmission and parts related to the transmission replacement.

My family and I were merging onto the highway when without warning, the automatic transmission bucked, making a loud thump sound, then it lost power nearly causing a severe accident. The transmission then began to hunt for gears, seemingly confused. It even cycled through 1st gear, my heart dropped, but luckily it did not engage 1st gear since that would have caused havoc at highway speeds. Afterwards, the vehicle regained some power but was suddenly limited to only two gears (5th and 9th). I immediately drove home, when entering my driveway the transmission could not engage reverse. Therefore I had to roll it in using forward momentum. I just had the vehicle serviced a few days ago because this issue happened before (not as severe). However, I was told the vehicle was operating fine and a leaky transmission pan was the culprit. After the transmission pan was replaced, I picked up the vehicle just yesterday (4/11/26), and this incident occurred today,(4/12/26). Please help, this transmission was rebuilt by Ford under warranty (60k mile powertrain warranty) just two years ago due to the notorious defects that have been ongoing. I contacted Ford corporate but they've refused to provide any help. This problem was confirmed by Ford corporate and the dealer, which led to the initial transmission rebuild (in 2024). However I fear this defect may not be repairable since the issue has returned and is more severe. I believe Ford was aware of this defect and did not disclose this information to me prior to buying. If I had known, I wouldn't have purchased this vehicle. Thank you for any support you could provide on this matter.

The vehicle just downshifted from 6th gear to 1st gear on the freeway nearly causing a accident and it caused a blown transmission.

The vehicle has less than 95,000 miles on it. The vehicle was purchased with around 83,000 (11/15/2024) started having issues with the transmission around 85,000. The truck will go from 6th to 3rd or it may go from 10th to 1st while running a good speed down the highway or it pulls out fine then goes to neutral. This is a safety issue. There needs to be a recall made on this vehicle before it causes one of us to get hurt. Please have someone to investigate. We need this matter corrected and I do not feel it should be out of our pocket to correct it. Yes, we could trade it but we do not want someone else to get hurt. Seeing as how the dealership sold it to us knowing this was an issue I'm sure they would not fix it to sell it. No incident has occured at this time. I'm trying to be proactive in preventing that.
