My 2019 f150 3. 5 ecooboost with the (10r80) transmission is unsafe to drive. The vehicle only has 66,000 miles and it is experiencing very serious transmission problems. I will lead off with the most dangerous safety issue. The 10r80 transmission will shift unexpectedly while traveling around 50 mph from 9th gear to 1st gear without actually engaging 1st gear, but simply becoming unresponsive on a highway at high speed. I was afraid I would be rear ended by another driver because I wasn't engaging any brake lights. A few other hazardous examples would be hard shifting such as from first gear to third gear and skipping second gear when gradually accelerating, downshifting hard when approaching a stop sign or red traffic light and shifting from sixth gear to seventh gear and simply not knowing which gear it wants to be in. The transmission is dangerously erratic. Recently the vehicle had a small (wrench) warning light illuminate. I referred to the manual and it indicates a powertrain malfunction. I brought my vehicle in for service and they did a software update. This did absolutely nothing and the transmission simply got worse. It was more erratic than ever. I scheduled another appointment for service and the dealership subsequently told me I need a new transmission. My truck has 66,000 miles on it. This is crazy. And a delicate 66,000 miles at that as I am meticulous with all maintenance intervals. The transmission is so erratic that I will not drive it. It is simply too unsafe and I do not want to cause any further damage. So in conclusion, I now have a 2019 f150 with 66,000 delicate miles on it, sitting in my driveway.

While slowing down at normal speeds, my 2013 Ford f?150 will suddenly and violently downshift into a much lower gear (appears to be 1st gear). When this happens, the rear wheels lock up briefly, causing the truck to skid and jerk forward. This creates a serious loss of control and a risk of collision. The issue is intermittent but recurring. It has happened multiple times under normal driving conditions. No warning lights remain on afterward, but traction control sometimes flashes during the event. I reported this to a Ford dealer, but they refused to repair it. This appears to match known issues with the 6r80 transmission and leadframe failures on similar f?150 models. This is a major safety hazard. If this occurs in traffic or on wet roads, it could easily cause a crash. I am requesting that NHTSA investigate and require Ford to address this defect.

While proceeding onto a busy highway the truck automatically shifted from 1st gear to 7th gear rendering it so sluggish it wouldnt barley move forward leaving in the middle of oncoming traffic. This has occured more than once and im now not using the truck.

My truck violently downshifted randomly and caused me to lose control for a little bit. I was lucky to narrowly avoid a crash. The truck is showing transmission range sensor codes after the truck downshifts harshly. My local Ford dealer did a diagnosis and confirmed that it has a faulty molded lead frame. However, they are refusing to cover the repair and are saying that I either pay them or stop driving the truck because the lead frame replacement is not explicitly listed as a remedy on the recall even though recall 26s28 lists the lead frame as a cause of the issue and even says that dealers will replace it at no cost if it has already gone bad, which mine has.

Transmission is locking itself into either 3rd or 5th gear and will not shift. Sometimes it will lock itself in 1st gear and not shift.

While driving at highway speed in 6th gear, the vehicle unexpectedly downshifted into what appeared to be 1st gear without warning. Immediately afterward, the vehicle falsely indicated that it was in reverse while still moving forward, and the backup camera activated during travel. The sudden downshift caused abrupt deceleration and created a significant safety concern due to the risk of loss of vehicle control and the possibility of being rear-ended by surrounding traffic. The issue has occurred multiple times and temporarily reset after shutting the vehicle off and restarting it. During the most recent incident, the vehicle also experienced a delayed restart. The vehicle was inspected by a Ford dealership, which retrieved diagnostic trouble codes p0706, p0707, and p1702 related to the transmission range sensor system. The dealership diagnosed failure of the molded leadframe/internal harness in the transmission main control, causing transmission range sensor faults and erratic shifting behavior. The dealership advised that the repair would cost approximately $4,000 and stated that the repair is not currently covered under the active Ford transmission recall. Prior to the failure, symptoms included intermittent erratic shifting behavior and false gear indication. No collision occurred, but the vehicle behavior created an unsafe driving condition at highway speeds. The failed component should be available for inspection through the servicing Ford dealership.

The onboard speed sensor (oss) failed, causing my vehicle to abruptly, and without advanced warning of a problem, to shift from 6th gear at 65mph, to 3rd gear. This caused an immediate deceleration in the middle of a flow of traffic travelling at highway speeds. Several cars behind me were forced to brake hard, nearly causing a multi-vehicle accident, putting those drivers, myself and my passengers all in danger. Ford had issued an extended warranty to cover this known defect in the leadframe assembly, but because it was never issued as a recall notice, I never received the notification or the option to bring the truck in for repairs. It is riduclously dangerous and negligent that this was never issued as a recall, when it has been acknowledged by Ford and is both wide-spread and extremely dangerous to both the vehicle driver as well as other drivers on the road.

In the second year of ownership I noticed that occasionally I would get no throttle response from the gas pedal when trying to accelerate. After several occurrences I began to pay close attention as to when this was occurring. I found that this occurs mostly, not exclusively, when I am slowing the vehicle to a near stop, not a full stop and then accelerating to continue, like slowing to round a corner on a green light and getting into traffic. For example, I was exiting a home depot parking lot, the driveway exits to the roadway. As I approached the driveway to enter the roadway I slowed, preparing to stop. Seeing no traffic on the roadway I then pushed the accelerator to enter the roadway. The pedal was dead, I got absolutely no acceleration. I pushed the pedal down slowly, nothing. I pushed the pedal to the floor, nothing. The truck rolled out onto the road, I coasted to the side of the road. Had there been traffic I'd have been hit. This has happened 20 times in two years and 80k miles. The most recent event was this week with my wife present, very scary, dead pedal, not throttle response. If you research "dead pedal" on google, you will get the following response: the "dead pedal" in the Ford F-150 powerboost—a dangerous lag or total loss of throttle response—is a widely reported issue, particularly when accelerating from low speeds, turning, or right after starting. [1, 2, 3] the cause can range from a software glitch to transmission issues or failing sensors. Ford said there was a TSB, however the work performed had no effect on the dead pedal on my truck. Invoice attached from March 2026, it just occurred again this week. I am going to trade the vehicle in but I doubt that Ford will disclose this flaw to the next buyer, it will be their's to discover, hopefully not by "accident". I am going to trade this vehicle in and I'm sure the new buyer will have no idea of this potentially deadly flaw.

The contact owns a 2016 Ford F-150. The contact stated that while driving at an undisclosed speed, the vehicle failed to shift gears properly with no warning lights illuminated. The vehicle was taken to an independent mechanic, where it was diagnosed that the transmission had failed and needed to be repaired. The vehicle was repaired; however, the failure recurred. The contact later received notification of NHTSA campaign number: 26v237000 (power train); however, the parts required for the recall repair were not yet available. The dealer was not contacted. The vehicle was not diagnosed or repaired. The contact stated that the manufacturer had exceeded a reasonable amount of time for the recall repair. The manufacturer was not made aware of the failure. The approximate failure mileage was 151,088.

Hard downshift caused my truck to slow suddenly and became very hesitant where the vehicle behind me had to slam on their brakes. I then pulled over when it was safe, turned the truck off and then attempted to turn back on with no success due to the shift indicator no longer lighting up. This matches up with the current recall for this particular vehicle.

What component or system failed or malfunctioned, and is it available for inspection upon request? the transmission is failing. Yes, it is available. How was your safety or the safety of others put at risk? my safety was put at risk by the vehicle losing forward motion while traveling through an intersection. Has the problem been reproduced or confirmed by a dealer or independent service center? yes I have a diagnosis for transmission rebuild or replace by both a dealer and an independent service center. Has the vehicle or component been inspected by the manufacturer, police, insurance representatives or others? no. Were there any warning lamps, messages or other symptoms of the problem prior to the failure, and when did they first appear? symptoms of slight gear slippage occurred prior to the incident.

2019 Ford F-150 4wd super crew 10 speed automatic with 51,330 miles. The transmission upon acceleration will slip, slow to shift, disengage, then slam into gear. I was afraid that the transmission would lock-up disengage causing an accident. There was a warning icon of a wrenchon dash display. I took to Ford dealer where they confirmed a cylinder bushing had slipped. They recommended to replace the transmission.

The contact owns a 2015 Ford F-150. The contact received a recall notification, NHTSA campaign number. 26v237000 (power train) however the parts were unavailable. The manufacturer was not contacted. The contact had not experienced any failure regarding the unrepaired recall.

1. Unexpected downshift into second gear while driving - like the engine is falling - causes severe jerk and sometimes truck revs/ goes into neutral - just revs. 2. Frozen tailgate latches and door latch defects 3. Additionally the transmission harsh shifting when cold (safety/drivability defect): when the vehicle is cold, the 10?speed transmission shifts harshly, hesitates, clunks, and delays engagement. This matches Ford’s transmission tsbs for calibration and adaptive learning issues. The dealership acknowledged the shifting issue but did not perform the required calibration or TSB procedures. The dealership refuses to document my reported symptoms or perform the TSB repairs unless the failure is happening in front of them. This prevents known defects from being repaired and leaves the vehicle in an unsafe condition. Ford customer service confirmed the shifting issue exists but the dealership still did not perform the calibration. Ford corp customer service didnt understand and manager didn’t even know what a TSB is:/ so no help at corporate. As chuck the manager stated he didn’t know what document I was referring to and I told him the number as well ? I contacted Ford customer service and a case was opened. A customer service manager named chuck returned my call. He stated that the TSB is “not a warranty” and that the dealership “has to duplicate the condition” before Ford will authorize the repair. I explained that the tailgate freezing issue cannot be duplicated on demand because it only occurs in cold overnight temperatures, not during daytime service hours. Despite this, Ford insisted the dealer must reproduce the failure, even though Ford’s own tsbs describe this exact cold?weather condition.

For the past several weeks, I have experienced an ongoing issue with my truck’s transmission shifting unpredictably. At random times, it becomes stuck in third gear, and while driving it has downshifted from fifth to third and then to first without warning. Even when stopped at a red light, the vehicle will sometimes remain in third gear. These incidents have created multiple safety concerns while driving and stopping. On 05/11/2026, my truck stopped completely in the middle of the road; fortunately, other drivers were able to stop and I was not hit, but I am concerned it is only a matter of time before a serious accident occurs. I also recently received a recall notice, which I was not expecting, and I had assumed this repair would be an out-of-pocket expense. I have contacted Ford regarding the recall repair, but I was advised they do not anticipate a remedy until July. Waiting several more months to drive a vehicle with ongoing drivetrain and downshifting problems feels unreasonable, and I am also concerned the condition may be causing additional damage to the transmission.

My vehicle has abrupt unintended downshifts straight down to first gear at fast speeds, which is causing rear-wheel lockage near heart attack and near-loss of control spinout. The sudden downshifting causes a loud violent high extreme rpm engine over rev. Sounding as if it is about to blow up or an internal explosion. This is occurring at highway speeds up to 70 mph. At these speeds, is an immediate risk to me and others! causing a fatal high-speed rollover or a multi-vehicle collision due to this malfunction! this was a recall 19s07 for my year of truck but my VIN was somehow was not on the list which I guess makes me not qualified unless I get into a crash and then have a lawsuit.

The contact's son owns a 2018 Ford F-150. The contact stated that while his son was driving on the interstate at 70 mph, the vehicle downshifted into 4th gear. No warning lights were illuminated. The local dealer was not contacted. The vehicle was not diagnosed or repaired. The manufacturer was contacted, who confirmed there were no recalls. The failure mileage was approximately 8,100.

Sudden downshift at highway speeds. Sudden shift into neutral at highway speeds. Transmission slams into lower gear causing rear end to make noise.
