Loud Engine Noise problems of the 2018 Ford F-150

My vehicle I purchased in 2019 second owner is now not running. I am unsure as to what is going on or why it stalled on me approximately 3 months ago. I filed a claim with my insurance company they closed it without assistance. I had it towed home. It will start up but it has a really loud clanging in the motor area. I don't know what's going on with it. My vehicle has not been neglected and it has been taken care of and I don't understand why it's not running to only be 2 years old. I was driving my vehicle to pick up my daughter from work in town. I noticed a very loud sound and I pulled over at a local circle k and it didn't start back up at that time. I am finding recalls, but not specific to my VIN.

Tl the contact owned a 2018 Ford F-150. The contact stated that he had taken his vehicle to thomasville Ford Lincoln (1515 e jackson st, thomasville, GA 31792) on multiple occasions due to abnormal noises coming from the engine, the transmission skipping gears, and the check engine light illuminating. On his last visit, a diagnostic was performed on the vehicle and multiple failure codes appeared on the vehicle. The diagnostic he received from the dealer stated for him to leave the vehicle at the dealer; however, the dealer allowed that contact to drive the vehicle home. Upon return of his vehicle, the contact stated that while driving at 10 mph after making a right turn, the vehicle accelerated independently without warning. The contact lost complete control of the vehicle and crashed into a telephone pole. The air bags deployed upon impact. The police were called to the scene and a police report was filed. The contact received medical attention at the scene and was transported to the hospital where he was treated for a concussion, an injured vertebra, a herniated disc, and injuries to his left arm, left hand and left thumb. The vehicle was totaled at the scene and was towed to an independent collision center. The same dealer was notified of the failure and offered no assistance. The manufacturer was notified of the failure and a claim was filed. The failure mileage was 4,354.

2,363 miles on the truck it downshifted on the hwy from 80 mph to 20 mph on its own, with a loud noise. Had to get in the slow lane so not to have a wreck. It is equipped with auto start, where the truck engine automatically stops at a stop sign or light and restarts on its own. The trucked shut itself off while in traffic and had to be put in park and restarted, almost causing a wreck. Took the truck back to the dealer again, when it made a loud noise and felt like we hit something when going 55 mph,the truck jolted we again got in the slow lane. Then when sitting in the driveway the motor started racing on its own not touching the excelerator. Had to turn off truck. We are afraid to take our grandkids in our new 2018 truck we are paying dearly for. The last time we took the truck to the dealer, they said there was nothing wrong with it. We are about to retire and wanted this truck to be our last, we have not even had it a year. We have done some checking online, we are not the only ones experiencing these types of problems.

My truck has a constant rattle/detonation/preignition noise during all driving. It is especially bad during hot summer months. It has only gotten worse as months have gone by. It is especially noticeable while climbing very slight uphill grades and at speeds between 35-55mph. It can be heard from inside and outside vehicle. The noise is coming from engine. A vibration and shudder can be felt in vehicle when noise is present. When it is really bad, the sound is very loud and sounds like a metal hammer banging on inside of engine. I was told this would get better with mileage, but has only gotten worse. I have audio and video recordings of noise over then past 10months. I am very worried that this engine is going to fail.
