--Exhaust leak, at left first band clamp downstream from catalyst --Safety is of immediate concern due to exhaust leak directly under driver seat --Local Ford dealership service dept did not fix leak --Exhaust leak was inspected and reported to local Ford dealer service dept- NOT fixed On 20 November 2023, I purchased a 2021 Ford F-150 XL, VIN: [XXX], from Crain Ford of Jacksonville, Arkansas, 1800 School Drive, Jacksonville, Arkansas 72076. Phone 501-436-4981. After driving the vehicle for a day, I noticed a fluid leak on my garage floor under the vehicle-??s engine area. On 21 November 2023, I took the vehicle to the dealership, which I bought the truck from, Crain Ford or Jacksonville, AR. They inspected the underside and found no leaks and suggested I just keep an eye out for any fluid leaks. The next week I kept watching for leaks, and each day I saw what appeared to be a fluid leak of some type or fluid on the floor of my garage. On 27 November 2023, I took the vehicle back t o the same dealership, Crain Ford, and I showed them a video of the leak I discovered. The video can be viewed at: [XXX] As the video shows, upon cold startup of the vehicle, you can see water leaking from the band clamp on the exhaust system just below the left catalyst. I fully understand that the fluid is water and is a byproduct of the combustion system and is normal. That is NOT the problem, the problem is, if water can leak out at the band clamp on the exhaust system, as shown, then so can deadly exhaust fumes right under the driver area. I showed the video to the Ford service dept foreman and he had a technician check the exhaust and assured me that the band clamps were at factory spec torque and they could smell or observe no leaks. I took the vehicle home. The next morning, there is still a deadly exhaust leak occurring at the band clamp on the exhaust pipe as I can see water dripping out, just as the first video showed INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

I was stopped at a red light at a busy intersection in an Atlanta suburb. I was several cars back from the red light. I saw the light turn green so I took my foot off of the brakes to engage auto start and barely tapped the gas and the truck dinged and showed me an error on the screen. I was so mortified and my heart started racing that I could barely read the error, all I remember seeing was "Shift to P." However, I tried to shift to Park and the shifter wouldn't do anything! I was desperately trying to engage the brake and shift to Park or Neutral and it wouldn't budge. I kept trying back and forth back and forth trying anything to get it to shift. It finally shifted to Park. I turned truck off. Opened the door, closed the door, and restarted engine and it had a slight hesitation but then let me shift down to Drive and proceed. Luckily, I had enough time to fix it before I started getting cussed out or honked at and possibly shot for having this happen on a busy intersection. My heart was beating so fast. So scary. I got home and connected my OBD scanner and no error codes were found. Sunny day, about 65 degrees, and truck had drive 55 miles to my Mom's a few hours before. This was on my way back to my house in Atlanta from my Mom's house an hour outside of Atlanta. I had no time to take a picture of the error on the screen because I was scared to death trying to get my truck to shift and drive. There was no reason for this error as I did not do anything differently. The auto start/stop engaged on its own when I come to a stop and then starts itself when I begin to depress the gas. Very concerning and I don't panic at all, but in this case...I sure did.

This is the 4th time since purchasing the truck that this event has happened with time having the most severe results. When shifting from reverse to park the shifter goes into park and jumps back into reverse. First event (after exiting the truck) the truck rolled into a shipping dock breaking a taillight and buckling the rear bumper. Next two I had one foot on running board and one foot in the truck ant was able to hit the brake stopping the truck. This fourth event one foot was on the running board and one on the ground. As truck went back the door flattened me to the ground and the front tires rolled over both of my legs. The truck rolled up an inclined parking lot, across a busy road and down a bank. I was driven by ambulance to the hospital and then transferred and airlifted to trauma center at Ruby Memorial Hospital. After the second event the local Ford dealer said they could not duplicate the event. The brakes do not hold even though they are depressed and set when the shifter is shifted.

Started with check engine light for cylinder 5 misfire and engine was running rough with loss of power. Took the truck to dealer and dealer reports compression loss as reason for engine failure. After doing some research there appears to be a major issue with the same engine (2.7 ecoboost) of the same year(2021) reported for the Bronco and F150 for catastrophic engine failure. I suspect this is the same engine failure that my truck experienced.

This problem has been ongoing, happening nonstop up to multiple times daily since Feb of 2022 and has spent now 70 days at the dealership in search of the issue. Luckily, the vehicle has not caused an incident yet, but I am afraid to drive it if I get it back from the dealer again as the issue has just gotten worse. The vehicle randomly while driving goes into a "limp mode" in which 1 of 2 things happens. 1) If unable to pull over immediately, the vehicle has very erratic throttle control and 2) the vehicle sometimes gives a warning about the "adavancetrack" system and will sometimes shift itself into neutral out of nowhere forcing you to coast to a stop no matter where or what type of street you are on. In researching this problem to help my dealer at first and now to try and protect myself while in a battle with ford, it seems to be a common problem discussed on many forums on the internet and facebook and seems quite common among the F-150 powerboost. Ford is refusing me a buyback at this time and ignoring the safety implications that my vehicle is having
