Automatic Transmission Torque Converter problems of the 2019 Ford F-150

The contact owns a 2019 Ford F-150. The contact stated that while driving on several occasions at various speeds, the vehicle shuddered and vibrated abnormally. The vehicle was taken to a dealer where it was diagnosed and determined that the tires were out of balance. The vehicle was repaired but the failure persisted. The vehicle was then taken to the same dealer again where it was diagnosed that the driveshaft needed to be replaced. The vehicle was repaired but the failure persisted. The vehicle was taken to another dealer where it was diagnosed that the torque convertor and valve body needed to be replaced. The vehicle was repaired but the failure persisted. The vehicle was taken back to the first dealer to be diagnosed but the failure was unable to be replicated. The manufacturer was notified of the failure. The failure mileage was approximately 77,000.

Vibration throughout the cabin between 54-60mph as we left the dealership. Brought it back a few days later and the service manager drove the truck with me and agreed that "there was defiantly an issue that needs to be addressed" . So I set up an appointment for the following week to drop the truck off. I dropped the truck off the following week. I got a call from the service manager (same one that drove the truck) and he asked if there was a level kit installed since he drove the truck last week. I replied yes, but that has nothing to do with the drivetrain vibration! he then stated that they will not look at this as a warranty issue anymore and would charge me (even though the problem occurred 100' after I left the parking lot with my brand new truck and the fact that he drove it and agreed there is defiantly an issue (that day!) I left and won't be back. Long story as short, I looked deep into this and found thousands of trucks with the same exact issue (2015-2020) and no fix from Ford yet: road force balance tires, no. Re-balance driveshaft, no. Replace rear axle, no. Replace driveshaft, no. Replace all rims, no. Wheel bearings, no. Brake components, no. Rear diff ring, no. Driveshaft carrier, no. Rear diff shims, no. 4-wheel alignment, no. U-joints, no. Replace all tires, no. Replace rear shocks, no. Pinon angle, no. Front drive shafts, no. Front diff, no. Shim pinion gear, no. Torque convertor, no. Trans valve body, no. Ring & pinion gears, no. This has been an issue since 2015. No recall. No TSB. Laughable.
