2019 Ford F-150

The contact owns a 2019 Ford F-150. The contact stated that while driving approximately 55 MPH, while attempting to depress the accelerator pedal, the vehicle hesitated and lost automotive power. The contact stated that seconds later, the vehicle started operating as intended. An independent mechanic was contacted. The vehicle was taken to an independent mechanic that the transmission needed to be replaced. The vehicle was not repaired. The manufacturer was notified of the failure. The approximate failure mileage was 99,000.

This is related to the incident report number XXX I filed previously. Before, between, and after that incident and this one reported today. The vehicle performs mostly normal, the severe issues are completely random and unpredictable. On 4/28/26 I started my truck and left to take my daughter to her [XXX] pediatrician appointment. I left my neighborhood and turned left into traffic. I didn’t speed up much, as the red light on the street stopped me about 100 yards down the road. Then, when green light hit I attempted to accelerate. The vehicle appeared to be stuck in 6th gear and would only rev up the RPMs to about 4000 and barely move forward. I managed to drive about 50ft and get the vehicle off onto the grass shoulder infront of someone’s house. I shifted the vehicle from park to drive and turned it on and off multiple times. This did not resolve the issue and I eventually put the truck in 4x4 in an attempt to make more power and drive forward. This entire time I’m on the shoulder of morning 55mph traffic, hazard lights on, with my infant in the back seat. I managed to get the vehicle to shift into 2nd gear and drive up the road. Once it came up to operating temperature it would shift into higher gears and we made it to the pediatrician. The truck stalled out similarly at two other stopped intersections and on the parking deck before we arrived at our destination. I called my wife and had her drive our daughter home after the appointment. I drove the truck home, on the same route, and it acted as if nothing was wrong. It shifted hard between 1-3rd but otherwise performed well enough. I have scheduled a transmission rebuild with a non-Ford service center for 5/4/26. It is extremely concerning that these issues are happening to myself and others with the 10R80 10-speed and Ford isn’t being forced to recall these vehicles. My truck is a 2019 with 86000 miles now.

The contact owns a 2019 Ford F-150. The contact stated that while driving at various speeds, the vehicle hesitated with the transmission slipping. The contact stated that the vehicle felt like it was being driven over a rumble strip. The vehicle was taken to the local dealer to be diagnosed, and it was determined that the transmission needed to be replaced. The vehicle was not yet repaired. The manufacturer was notified of the failure, but no assistance was provided. The failure mileage was 100,000.

I am the owner of a 2019 Ford F-150 Lariat equipped with a 10-sp transmission. In late 2021, early 2022 - whiled the vehicle still had warranty - I reported to a Ford dealership that the transmission was experiencing harsh shifting and jerking. At that time, I was informed that no issue could be identified. I complained of this each time I took the vehicle into the dealer for an oil change. After the warranty expired on this vehicle in 2023, the condition worsened. By 2024, the transmission began intermittently shifting into neutral while the vehicle was in motion. This occurred both when accelerating through lower gears (notably between 3rd, 4th, and 8th,9th) and while driving at highway speeds. These incidents created serious safety risks. On multiple occasions, the vehicle unexpectedly shifted into neutral while changing lanes on the interstate highway. The vehicle RPMs spiked and I was unable to regain power and had to maneuver to the shoulder while a semi-truck traveling at high speed approached from behind. This placed me in a dangerous and potentially life-threatening situation. On another occassion, the vehicle unexpectedly shifted into neutral while I was proceeding through intersections after a green light, leaving me without power, and unable to shift back into drive in active traffic. There were no service, or warning lights on prior to these failures. The issues occurred suddenly without notice, creating unpredictable and hazardous conditions. Warning indicators only appeared after the condition progressed where the vehicle became un-driveable. Two dealers have since inspected the vehicle and confirmed that the internal transmission components have failed. I was advised that a full transmission replacement is necessary. The issue has occurred multiple times and has progressively worsened since it was first reported under warranty. There was failure to identify and address safety risks sooner and this is extremely concerning. This is a known issue!

4/10/26 - I left my neighborhood to turn right, from a stop, onto a 55 mph highway. Headed to the grocery store, with my 6-month old daughter. The trucks transmission (F150 10R80 10 speed) would not shift any higher than 2nd gear, of 10 gears. This caused the truck to not accelerate at a reasonable speed and only do about 15mph. Two cars behind me nearly collided with me as I could not achieve or maintain speed. I quickly adjusted the steering and pulled the truck over on the grass shoulder. This avoided any accidents and only scared myself, my daughter, and two other drivers behind me. My daughter and I could have easily been severely wounded or killed. I did not know or expect the transmission would suddenly fail. This failure to change gears or hard shifts is a classic symptom of the Ford 10R80 transmissions CDF drum failure. Ford knows about this issue and refuses to recall these vehicles or repair them unless they are under warranty. My truck has 85k miles, just outside the 60k mile warranty. My neighbor with two small children has the same truck with the same issue, also potentially endangering their lives. This should be a forced recall by Ford to protect everyone on the road.

Transmission Gear Failure VEHICLE: 2019 Ford F-150 MILEAGE: 67,000 ​Description of Incident: I am reporting a catastrophic internal mechanical failure of the 10R80 transmission. While driving, the vehicle emitted a strong, pungent odor of burnt transmission fluid followed by a total loss of gear engagement. The failure was sudden and occurred without a "Check Engine" light or warning, leaving the vehicle stranded in a dangerous position in active traffic. ​Technical Assessment of Cause: Upon professional teardown, it was determined that the internal gear sets were severely damaged and required full replacement. The transmission fluid was heavily oxidized (burnt), and the planetary gear assemblies showed signs of extreme thermal distress and mechanical chipping. This indicates a failure of the internal lubrication system or a structural defect in the gear hardening process, leading to metal-on-metal contact and total component failure at only 67,000 miles. ​Safety Concern: The suddenness of this gear failure creates a significant risk of a "stalled vehicle" scenario in high-speed environments. Furthermore, a mechanical gear failure carries the risk of internal components fracturing and potentially locking the rear wheels, which could lead to a complete loss of vehicle control. This is a premature failure of a major powertrain component that is advertised to last the life of the vehicle.
