There is an issue with the transmission slipping or not engaging properly. There is a strong and often loud jolt with a hard shift at times. It will also simply not engage in the next gear other times. I can be pushing down on the gas and you can hear the engine revving but the truck isn't picking up speed. This has been the most dangerous part of the transmission issues. If I'm pulling out to cross an intersection or turn onto a street and the truck isn't moving, my family is in extreme danger of being hit by oncoming traffic. The vehicle was looked at for this issue at the Ford dealership, Mel Hambelton, in Wichita, KS previously. The issue seemed to be better, almost non-existent, after I believe they reset some code. The problem has returned in the last couple of weeks and is much worse. We have an appointment Nov. 1st to have it looked into again. I don't feel very safe driving my vehicle and we couldn't get it in for at least 3 weeks to the same dealership so we are using the Ford Dealership in Hutchinson, KS to hopefully get it fixed sooner. There is no warning/check engine associate with this issue.

F150 will not shift out of gears. Example, stays in 1st gear, regardless of speed. Ford dealer said it was a "Molded Leadframe" transmission problem at first, then decided to "reprogram" the computer to eliminate the shifting problem. Problem returned a few weeks later. Now shifts immediately into 7th gear (instead of 1st) and stays in that gear only. Ford dealer is not able to acquire the "molded lead frame" part to repair my vehicle. This problem was subject to an earlier year recalled which does not cover my 2017 vehicle.

While traveling down the interstate at the posted speed limit of 70 MPH in the fast lane, I experienced the vehicle immediately hesitating without pressing the brake and a loud grinding noise in the front drivers side and caused me to put on my brakes, change lanes and drive off to the side of the road. The grinding stopped and then it happened again about 20 more miles down the road. I was able to get it to the Ford dealership and was told it was a defective IWE Check Valve which attempted to put my vehicle into 4 Wheel Drive. As a result, I had to replace the Front IWE and the new & improved IWE Check Valve which was designed to prevent this from happening in the future. For obvious reasons, I became upset that a known issue with defective IWE check valves causes this event to occur. After exploring the internet for this same exact problem, I found this has been going on for more than 5 years. I now have the "corrected" part, but my major concern is that while I did not get into an accident this time, what is to prevent it from happening to someone who may not exhibit the same composure and causes their vehicle to crash into someone else and death or injury is caused and could have been prevented with a relatively cheap replacement part.

Truck downshifts periodically from 3rd to 2nd gear or from 4 to 3 of 4th to 2nd, for no reason, while keeping speed same on flat road. This causes tire squealing action in some cases and is unsafe. Also, at the same time, rear motion sensor system failure light comes on with an OK button. I select the button and then a wrench sign lights up indicating service requires. Sometimes also a check engine light comes on. Sometimes also the display showing what gear truck is in goes blank, or flutters through all gears. Sometimes a fan/generator comes on as well for no apparent reason. Sometimes the truck is goes in to no gear at all (neutral?) while I am moving. I pull over, restart the engine and the problems usually go away. This problem was reported to 2 Ford dealers (Cella and Bergey) on about 7/2022 and 8/2022. They gave me very different assessments of the problem, the most expensive being a new lead frame ($1,300) Problems originally started around 3/2022. Truck has about 35,000 miles on it.

I was on a highway in rain on cruise control approaching an off ramp. My speed was 72 mph as set by cruise control. I applied the brakes to disengage and slow for the off-ramp which is sharp. As I approached I started to apply more brake pressure. The vehicle began accelerating as I was going into the turn. I stomped on the brakes and the brakes went to the floor repeatedly while still accelerating. I navigated the turn at high speed with the back end breaking loose and fish tailing. I barely made it around and proceeded to hit the off button frantically. The truck shut down and I coasted to the side of the road. I had my 7yr old girl in the truck. It was terrifying. When I restarted the truck the cruise control was disengaged and the brakes worked

Today was the worst of the 4 times that this same situation occurred. I was driving in traffic on the highway in downtown atlanta when I accelerated and switched lanes to pass a slow moving vehicle. The truck accelerated fine but would not stop accelerating when I removed my foot from the gas peddle. I had to break hard to avoid hitting another car. As soon as I removed my foot from the break, the car engine revved up and accelerated forward again even though I was not touching the gas. This went on for almost 5 minutes and was very scary. I could have easily had an accident. At first, thought is was the cruise control kicking in but it was off. Each of the 4 situations occurred when trying to pass another vehicle. I reported the problem to my dealership back on August 12th when it happened the 3rd time. They could not find anything wrong. I know there is a very dangerous problem with my truck and need to find a solution before I or someone gets hurt.

In motion the throttle body is very slow in responding to commands given to it by gas pedal causing unsafe delay in acceleration and unexpected minor increase in speed in stop and go traffic.

First event: While I was driving back from the countryside on a two way road ' single lane -, I overtook a big truck on an uphill area, and all the sudden my truck died. Lost all the power and I had to make an emergency maneuver to avoid the big truck I was overtaking and also the car that appeared at the curve ahead. It was close. I almost crashed. After calmed me down, I step out of the truck, opened the capot while the engine was idling and making this huge 'valve' noise. I took my phone and recorded a video. Some component on a side of the valve cover was moving and making that noise and all the sudden, I smelled gas, looked down the scape manifold and saw gas all over it. I ran back to the cabin and turned the engine off, took the extinguisher and ran back to the capot. Fortunately nothing happened. Second event: While driving on the highway, with the cruise control on at 120 km/H, on a pretty flat area, the gear shifted from 10 to 7 with no reason at all, and I felt like the truck started to activate the brakes. The highway was clear in front of me. No car or obstacles were near the front of the truck. Seconds after that, the engine started to fail, dropping the rpms like those old mechanical carburetor stuck with a dirt and suddenly, all got back to normal. Fortunately was almost reaching the toll control to access to my city. So I slowed down to 50 kms/H, put my foot on over the brakes and started to press it very gentle. Suddenly and with no warning, the truck sped up itself full gas and I had to Dodge a car that was in front of me driving on the line to the toll and press the brake pedal very hard. Several lights invaded the dashboard; low coolant, check engine, the dash board dimmer light and others that I couldn't saw on this fast flash of lights. It was like the cpu was crazy. After that, truck went back to normal, but several obd2 errors got stored.

This is a brand new truck I have purchased about 3 weeks ago. I have noticed some strange behavior of the accelerator pedal, I had an impression that sometimes it was getting a bit stuck or changed the position on its own. Today I have discovered by myself that the accelerator pedal assembly is completely loose, all 3 bolts are not torqued at all, I could turn them with my bare fingers. This explains the strange behavior I observed. Last week I complained to the dealer about the rough downshifting, they did a test drive (!) and found nothing wrong. I have made a video, I hope it will better explain the nature of the problem: Https://youtu.be/B9ijtdtdqya I definitely consider this a safety issue and I suspect Ford does not have adequate quality control to ensure that the accelerator assembly is installed correctly. I am going to see the dealer tomorrow morning.
