2018 Ford F-150: sudden unintended acceleration

Filed Sep 17, 2026 · Transmission · TN

After Fords TCM recall the truck’s transmission has not acted correctly, very hard shifts, staggered shifting and warning lights for shifting issues or low power due to loss of signal from computer. It has gotten worse it now is sticking in 4th and 7th gear, acts as if slipping and completely stopped the truck in a busy intersection where I had to shut the vehicle off and restart before it would go in gear manually. Truck has lunged forward in reverse, went into low gear on the interstate and have given codes for fault detection. I’ve had the vehicle look at by a certified mechanic and his computer shows no connection between computer and transmission then shows partial connection and the full connection. Torque Converter shows good and so do the cliches and solenoids. This is dangerous and could cause an accident if not fixed, whatever ford’s update was has made my computer loose connection with the transmission and has put a fault that could possibly cause an accident or fire.

At about 70,000 miles, my truck's transmission began to shift extremely hard in the low gears, between first and fourth, and at times of sudden acceleration (from a stop sign or on ramp) the transmission would fail and I would need to put the vehicle in neutral then back into drive. This happened a few times before I had to have my transmission replaced at a cost of about $9,000. I read that there is an investigation into this issue but the investigation does not include 2018 trucks. The investigation should include 2018 to 2021 models as well.

While attempting a left-hand turn across two lanes of oncoming traffic, the vehicle experienced a sudden and total loss of motive power. Upon acceleration, the 10R80 transmission slipped out of gear, causing the engine RPMs to spike (rev) without transferring power to the wheels. This left the vehicle momentarily stationary in the path of oncoming traffic, nearly resulting in a broadside collision. After a delay, the transmission violently engaged, causing the vehicle to lunge forward with enough force to spin the tires and nearly cause a loss of steering control. There were no prior warning lights, "limp mode" indicators, or messages on the dashboard before or during the failure. The vehicle was taken to a Ford dealership, where technicians confirmed a failure internal to the 10R80 transmission. The service department stated this is a "known issue" with this transmission model and recommended a full replacement. This failure represents a significant safety hazard due to the unpredictable loss of power in high-stakes driving situations.

At or around 85,000 miles, I noticed my vehicle hesitating going into 3rd or 4th gear. Shortly thereafter, the vehicle began hard shifting into that 3rd/4th gear. Occasionally, the vehicle would lunge forward unexpectantly during this gear shift change. There have been several warning lights (wrench icon) appear on the dash. Also, on several occasions, I have experienced a sudden loss of power when trying to accelerate the vehicle as in a passing situation or merging into traffic. Upon doing research on the internet, I discovered hundreds of reports of Ford truck owners experiencing the same problems that I am having. These complaints are from 2018-2023 Ford truck owners whose trucks have the 10 speed transmissions. These defective transmissions need to be recalled not only because they pose a safety concern with the sudden lunging forward but also with the loss of power that sometimes occurs. Many owners have taken their vehicles to Ford dealerships and other mechanics to be told they need new transmissions or their transmissions need to be rebuilt. The cost for these new or rebuilt transmissions are from $5500 to $11,000. These are transmissions with mostly less than 100,000 miles on them. I haven't taken my vehicle to a mechanic (Ford or private) because I feel like I'm just going to be told that I need a new or rebuilt transmission. I am only driving my Ford F-150 within my local town because I'm afraid to drive it out of town. I'm so afraid that I may get into heavy traffic and the vehicle decides to lunge forward causing an accident or that I may need to pass or merge into traffic on an interstate and the vehicle loses power and I get rear-ended. Ford is aware of these defective transmissions and need to recall these vehicles with these 10 speed transmissions.

While driving i was coming to a stop approaching a traffic circle. I had to yield the car already in the circle as i was stopping the truck made a clunk and lunged forward while i was breaking forcing me to enter the circle before it was safe to do so. I almost collided with the approaching vehicle with a child in the car. Another instance the vehicle between shifting gears randomly lost power as if it shifted into neutral, then a loud clunk as it finally found the gear when it did the vehicle lunged forward. Another instance with the vehicle in park i started the engine, after the starter finished and the engine turned over there was a loud clunk and the vehicle lunged forward in park enough that the tires made a noise and could have hit a parked car in-front of me. The dealership said it is a known issues with the 10R80 transmission and will cost me $8,000 to $10,000 to repair. This transmission has always clunked and missed gears since i bought it new in 2018 and i have had it looked at multiple times, but the dealerships always said its “normal” Ford knows this is an issues and has not issued a recall and it is very dangerous.

10R80 Transmission Transmission has very prolonged delay when switching to certain gears which results in loss of power when merging onto roads causing near misses because it takes so long to engage the gear. Truck has zero power during this shift delay. The shift delays are caused by an issue that ford KNOWS about where a bushing (CDF drum) shifts a little bit inside the transmission. Vehicle is not safe to drive. When the gear finally does engage, there is a violent jerk/surge forward which can be impossible to control.

Experienced a rapid, dangerous downshift on the highway that took me from 70 mph to 50 mph. After that, the truck shifts roughly into gears 1-7 then hesitates into gears 8-10. Additionally, trucks downshifts cause passengers to lunge forward at random times as it skips and slips in and out of all gears. I took the vehicle to my local Ford dealer immediately and was told i need to spend $10,000 on a new transmission. After researching, this is a KNOWN issue with this year and model of truck. It is grounds for a recall and I see there are a few already in process along with a class action lawsuit. Please help! I am without a working vehicle and have young children.

𝗤𝘂𝗲𝘀𝘁𝗶𝗼𝗻 𝟭: Vehicle is available for inspection. 1) Transmission: Vehicle consistently shifts aggressively around 4th gear (10 speeds total). Vehicle lurches when going above 3rd, however, it shifts correctly after 5th gear. 2) Acceleration: Vehicle randomly lurches forward or backward, depending on whether or not the vehicle is in Drive or Reverse, almost like you are slamming on the pedal, but without having pressed the pedal. This has only happened a couple of times, but it's very noticeable when it does. 3) Auto Start Stop Module: Vehicle will shut off while stopped or almost at a complete stop and the dashboard will have an error message with the auto start stop symbol and instructions that say to put the vehicle in park and turn the key to the off position and then back on. This has happened with the auto start stop button on the truck being pushed in the OFF position. This has happened in traffic multiple times, and once while reversing. 𝗤𝘂𝗲𝘀𝘁𝗶𝗼𝗻 𝟮: The vehicle turning off randomly or suddenly accelerating poses a large safety issue when driving on any city streets or parking lots. 𝗤𝘂𝗲𝘀𝘁𝗶𝗼𝗻 𝟯: Not as of yet, however, the 10r80 transmission in this truck has already been recalled on similar models and other Ford vehicles.
