2019 Ford F-150: sudden loss of power

Filed Oct 28, 2026 · Engine, Transmission · UT

I am filing a safety complaint regarding a known manufacturing defect in the Variable Cam Timing (VCT) system of my 2019 Ford F-150 equipped with the 2nd Generation 3.5L EcoBoost engine. The vehicle currently has approximately 80,000 miles. The vehicle is experiencing severe cam phaser degradation due to failing internal locking pins, a widespread issue previously acknowledged by Ford under Customer Satisfaction Program 21N03. This mechanical failure causes a violent rattling noise upon cold starts, indicating a lack of oil pressure retention. More critically, as the component degradation worsens, it causes significant engine lag, severe hesitation during acceleration, and intermittent stalling. This presents a severe safety hazard, as the vehicle has experienced sudden power loss and hesitation while attempting to merge into high-speed highway traffic and execute turns, creating an immediate risk of a collision. Despite this being a well-documented factory defect in the 2017–2019 model years, Ford corporate has declined out-of-warranty or goodwill assistance to resolve the issue. I am requesting that the federal safety agency investigate this systemic powertrain defect, as the unpredictable loss of propulsion and stalling poses a direct threat to driver and passenger safety.

So, the transmission is slipping and causing the truck to lose power and jerk and not shift properly. I have had it looked at found out that the same transmission that was on a recall for other trucks is the same that is in mine, yet NO recall has been made. I have had no warning signs or any warning before it started shifting different.

While driving on a residential road, my 2019 Ford F-150 (10R80 10-speed automatic with 88k miles) lost power to the wheels – the engine revved but the truck would not move. It did not recover after I shifted to reverse, then park, then shut the engine off and restarted. The vehicle had to be towed. This followed an earlier event on or around July 7, 2026 (at ~86,500 miles) where the transmission failed to downshift from 4th gear at a stop and stalled the engine, recovering only after cycling the shifter. The truck has a history of hard shifting into and past 4th gear for over a year now. No warning lights appeared during these events. The safety risk is that the transmission intermittently loses drive engagement and can stall the vehicle in traffic. When the engine stalls, power brake assist is lost after one or two pedal applications. Had the loss of drive occurred in an intersection or on the highway rather than a low-speed residential road, it could have caused a collision. An authorized Ford dealer has twice been unable to duplicate the fault on test drives, consistent with the intermittent 10R80 CDF clutch cylinder hydraulic leak described in Ford TSB 25-2126. The dealer’s technician suspects an F-clutch concern.

The transmission started to clunk into gear very heavily when I started my drive and then as I was driving down the highway going 60mph, the 10r80 transmission suddenly downshifted from 7th gear to 1st gear, and jolted the truck and I lost all power and it took around 5-7 seconds before the throttle was registering again to pick up speed. A car was a ways behind me but if it had been closer, there is no doubt I would have likely been hit. After this happened, in trying to increase speed back to the speed limit, the transmission would not shift back into 7th gear, and a wrench and code popped up on the dash.

I started noticing hard and delayed shifts from 7th into 8th gear. My RPM's were not increasing when this happened, and then on a very crowded major road I lost all power, vehicle shut off and drifted, then started up and jerked again very hard. This failure could have caused a severe accident and jeopardized the well being of my wife, daughter, her friend and myself along with any other people that could of potentially been involved in a collision if one had occurred. My dash showed no warning lights. After lots of research and consultation with a private owned mechanic shop, I learned the 2019 F150 has a sever and known transmission issue with the learning tables and the transmission control module resulting in failure. Further research reveled a law suit against ford ([XXX] v. Ford Motor Company (Case No. [XXX] in the U.S. District Court for the Northern District of Illinois, targets Ford over alleged defects in the 10R80 10-speed automatic transmissions equipped in 2017–2020 Ford F-150 trucks) regarding this exact issue I was having with my truck, with only 72,000 miles on it! Bob Bell Ford in Glen Burnie Maryland, was less than helpful and the staff was rude when I was explaining what was happening and the information I learned, and quoted me a price of around $12,000.00 to replace the transmission, and that they knew there was a problem with that transmission. I had the vehicle repaired by Glen Burnie Transmission in Glen Burnie Maryland for $8,200.00. That shop told me that they replace several of these transmissions a month (confirming it is a sever issue) and the service tech could tell me what the 8th digit in my vin was based on the symptoms, and he was spot on! I was told the CDF drum and bushings failing—that cause harsh, erratic shifting, sudden lunging, jerking, hesitation, and gear slipping This repair costed me $8200.00 to replace, and another $450 to Bob Bell Ford for them to repeat to me what I already told them.

This problem started a few months ago. In the first few minutes of driving my truck each morning i have been experiencing problems with my truck shifting. Sometimes there is a lag. Sometimes there is unexpected shift. Sometimes it jumps from 10th gear to 1st. It can be jarring at times. Then by the time i get to where i am going the problems seem to go away. Lately, the problems show up slightly, later in the day. And most recently, the little wrench light came on, indicating a "Powertrain malfunction / Reduced power" With the description "The transmission control module has detected a concern when trying to shift to 7th gear. A failsafe logic disable 7th gear for the remainder of this key cycle." I had my truck towed to a Ford dealership, and they claim i need a whole new transmission! When i researched this it seems that this is a very common problem with the Ford F150 and the 10R80 transmission. It was recommended that i file a complaint with the federal safety agency

The contact owns a 2019 Ford F-150. The contact stated that while driving approximately 40 MPH, the vehicle abruptly lost power, decelerated and stalled. The contact was able to maneuver the vehicle off the road and parked the vehicle. The vehicle was later towed to the local mechanic who diagnosed that the driveshaft had sheared off inside the shaft and the vehicle was undrivable and informed the contact that the drive shaft needed to be replaced. The vehicle was not yet repaired. The local dealer was notified of the failure and informed that the vehicle was not included in the federal safety agency Campaign Number: 21V986000 (POWER TRAIN, STRUCTURE). The contact stated that the vehicle had experienced the failure listed in the recall. The manufacturer was not notified of the failure. The failure mileage was 212,000.

While driving on a highway, my 2019 Ford F-150 suddenly lost power during acceleration due to a transmission malfunction. The truck hesitated and failed to respond to the accelerator, nearly causing a rear-end collision. The transmission required a major overhaul at approximately 53,000 miles, yet the same symptoms returned shortly after the repair. Around 56,000 miles, the engine also developed a cam phaser/timing chain failure requiring extensive repairs. These major drivetrain failures at such low mileage raise serious safety concerns and indicate a potential manufacturing defect. I believe this vehicle poses an unreasonable safety risk to drivers and the public.

"Upon shifting the vehicle into the 'Drive' (D) position, the transmission produces a loud, audible striking/clunking sound. When accelerating from a stop, the transmission consistently slips and exhibits severe hesitation. Furthermore, the vehicle experiences a complete loss of power/engagement when attempting to shift into 4th gear, creating a safety hazard during higher-speed driving. These symptoms occur regularly and affect the predictable control of the vehicle."

Since before my 60K warranty expired, I have experienced clunking when automatic transmission is espeically shifting down from about 4 to 3 of the 10 speeds. It has gotten worse, and it actually has good and bad days just like you and me. The other day it felt so severe that it seemed the entire truck would implode and then I would be sitting duck, or worse, hit something out of control or from quickly losing power steering. I know this issue is known, and there are now lawsuits. Date below is first onset. Dealerships have told me all sorts of crazy options to solve it over the years, from changing transmission fluid, to replacing transmission.
