Adaptive Cruise Control problems of the 2019 Ford Expedition

I was driving and felt a clunk in transmission and lost power and almost got rear ended. The wrench light came on so I pulled over and turned off the vehicle. I restarted and it ran fine but the transmission is dangerous, I don't want that to happen again. The transmission constantly hard shifts. This was at 2am in the morning when I was driving from FL to MD.

The transmission has delays in shifting up and down causing unpredictable ability to accelerate when entering highways in front of speeding vehicles. The Ford technician confirmed the issue and stated that ultimately, the transmission could fail at anytime. The Ford technician strongly encouraged me to replace the transmission after his the dealership inspected the vehicle and were able to replicate the problem. This was an out of pocket expense. Ford has detailed this failure in technical service bulletin 25-2023 which states harsh engagement delayed engagement harsh shift delayed shift.

Fyi request #588758 let me know if you have any info I sent this letter on November 20, 2022 and as of January 10, 2023 I have had no response from Ford motors: james d. Farley, jr. Office of the ceo Ford motor company 1 american road dearborn, michigan 48126 2019 Ford Expedition acc-cruise control potential safety problem mr. Farley, I wanted to let you know of a bizarre recent acc cruise control issue with my 2019 Expedition. It has ~30,000 miles on it and has performed very well without problem before and after this incident. Several weeks ago I was driving on an interstate highway in a construction zone with stop and go traffic, and had the acc on. I slowed down behind a dull colored black Chevrolet pickup that had dark lens covers over the tail lights and a dark cover over the license plate to about 5 mph. Suddenly the acc had full acceleration then the auto safety braking slowed me abruptly, then the acc hit full acceleration again and the auto brake engaged. I turned the acc off, and then back on, and it did the exact acceleration and safety braking so I turned the acc off. There was no accident or problem other than this acceleration/braking sequence. When I no longer was behind the pickup I tried and acc and it has worked perfectly since then, as it had prior to this bizarre issue the acc seemed to not see this pickup truck but the auto safety braking system did. The pickup was an unusual non factory appearing paint job, dark gray or black not just a primer, and the tail lights and license plates also had some darkening coating. It seemed to be stealth to the acc, but not to the braking system. Maybe referred to the engineering section of the acc group to see if they have heard of this before or have any idea what occurred to help prevent any risks involving the Ford acc system. Again there was no accident or collision, only the sudden acceleration/braking. This only occurred one time on this 2019 Expedition and never on our other Ford products.
