Approximately 2 weeks after purchasing the truck I noticed some harsh shifting, jerking, and sudden acceleration, and hesitation issues. They were intermittent and I was advised this is not uncommon with this model vehicle. However, these issues have become more frequent and severe. Next, I noticed the gears began slipping and the truck seemed to not be able to -??find-?? the gear it needed to be in. The transmission would slam into gear or begin slipping under acceleration. There is no rhyme or reason to it, I have not been able to pinpoint it to a specific gear or up/down shift. It simply loses power and neither the gas nor brake work. It will coast until the wrench (check engine?) symbol comes on and then the gas will function. This week the transmission has started intermittently locking into a specific gear without the ability to shift. It-??s now happened 3 times. You cannot reverse or drive, the transmission puts itself in park while the dash still indicates its in drive or reverse. After parking the truck for a couple of hours, I could start and drive as usual. Most importantly, twice Saturday the truck seemed to shift out of gear, so hard my head hit the steering wheel, and lost power going 70mph on I64. I have attempted to video these events to help diagnose the issues, but obviously driving and recording are dangerous and difficult.

The contact owns a 2019 Ford F-150. The contact stated that while in park, the vehicle accelerated independently. While driving at unknown speeds, the vehicle accelerated without the accelerator pedal being depressed. The driver was unable to control the vehicle. The check engine warning and power train warning lights were illuminated. The vehicle was taken to an independent mechanic, who stated that the failure was related to the transmission. The contact called the local dealer, but the vehicle was not diagnosed or repaired. The manufacturer was not contacted. The failure mileage was 90,000.

PowerTrain Malfunction Failed, notification on my vehicle appeared on 4/28/23, although I had been notifying dealer for 3 months prior the safety issue I was experiencing, and nearly got killed on a major interstate, on 4/26/23 my truck stalled as foot pedal would not work. Major safety of semi-trucks and other vehicles on main I30 Interstate were trying to avoid hitting me due to my vehicle abruptly downshifts from 10- to 1st gear. Foot pedal inoperable during that time. Yes, the dealer and Ford on 4/28/23 provided me a rental vehicle after my near collision experience until they figure out what to do, replace transmission or rebuild, unresolved. No the vehicle had no warnings, but did have symptons, which I took to dealer and they ran a diagnostic, and found nothing, they said there are TSBs out there with the downshifting issues, and stalling, jerking of transmission. But they said just wait it out initially, and I had to call Ford Corporate relations and raise the roof, after I nearly got killed by semi trucks from being stuck in a major interstate highway. December 2022 when it began, the dealer kept doing a reset, which seemed to make it worse, then when I told them how unsafe it was they ignored me, until April 26th when I left a voice mail after nearly being killed. I demanded service as I have a warranty and they ignored the symptoms for so long. Multiple people could have been killed on the interstate when my truck stalled, I had to try and coast to the side of interstate as the truck foot pedal did not work after downshifting from 8 to 1.

Driving back from, San Antonio, Tx., to Millsap, Tx., in my 2019 Ford F-150 truck, I experienced down shifting and up shifting hard. It was making driving very difficult and dangerous. My Ford App alerted me that there was a Powertrain Malfunction. The little wrench light came on the dash indicating Powertrain problems. I was very concerned for my safety. I have turned it into, Southwest Ford, in, Hudson Oaks, Texas. I was not told that this was an issue with this year model, nor have I received anything in the mail about it. The Ford Dealership above was where I bought the truck and all the oil changes, ect., have been done. I have researched this problem and have come across a class action lawsuit that describes what happened with my truck. Ford has not notified me to this problem. What else should I do to resolve this?

The transmission started shifting down and up uncontrollably while traveling down the highway at 75 MPH. It would bounce between 9 and 10 gear and then down to 5 and 6, all within seconds. Was not towing anything, and it-€™s not the first time it-€™s happened. A wrench icon appeared, saying -€œsee manual-€. Transmission temp showed 240 degrees. Within 5 minutes we-€™d pulled over and turned vehicle off. As we were slowing down exiting freeway, gear shifting was extremely pronounced.

on 3/6/2020 I was in a serious car accident in the vehicle. which required surgeries for not only myself but also other drivers on the road. The driver air bags did not deploy, the turck was totaled and had body damage around the entire vehicle. There was a blood stain from my head hitting the driver door window but no air bag deployment. The gas pedal was not attached when reviewing the photos taken. The collision detection did not detect. we have asked Ford Motor Company to come and look at the car as it has been in a protective hold but the response from FMC was that due to covid they would not send anyone and we were left on out own. There were no warning messages, lamps, lights or indicators prior to the collision.

The vehicle hesitates while speeding up. This hesitation is dangerous in situations like entering and exiting the highway from an off-ramp, where acceleration is necessary to merge with traffic. The vehicle hesitation to accelerate is unpredictable. I tired several times to upload documentation as jpeg files. Each time I get Failed to Upload message. Consumer stated vehicle's hesitation has occurred several times and vehicle has not been repaired.

While driving on the highway today, I needed to accel quickly to avoid being in the blind spot of another truck as I was merging onto a different highway. After getting past the truck, I let off the accelerator pedal, but the vehicle continued to speed up. When this happened, I assumed that the cruise control was somehow trying to resume so I tapped the brakes to cancel it, but nothing happened. I then put on brakes, but it was simply fighting the engine as the vehicle continued to accelerate. I then tried pressing both the cancel button and the off button on my cruise control, but the vehicle continued to accelerate. By this time I was easily up to about 85 mph and had now other choice than to put the truck in neutral. I left it in neutral for about 3 or 4 seconds and then put it back into drive and the acceleration problem was resolved. This could have been a very bad situation for an inexperienced driver. I plan on stopping at the dealer where I purchased the vehicle last year and report it to them as well.

This happened twice today 10/24/2020. First time I was stopped at a turning light on a main road and as soon as I let off the break the engine shutoff. Second time I was in a residential neighborhood making a turn and the engine shutoff once again displaying the image attached.

While driving the vehicle on a city street it started to accelerate on it's own and I had to slam on the breaks because of it doing that. Again one December 20th 2019 it did it again. I dont know what's causing it to be doing that but I've taking it to the dealership and nothing can be found wrong.

When driving in adaptive cruise control the vehicle will agreesively decelerate when passing on the left side of a large profile vehicle. The greater the speed difference between the two vehicles the greater the rate of deceleration. If the speed difference is about 35 mph or greater the collision avoidance system will activate. This is potentially very dangerous on a crowded interstate with following vehicles very close.
