On June 23rd while driving my 2021 XL SuperCrew with the 3.5L EcoBoost engine, the engine quit while I was driving about 30mph. I pushed the accelerator slightly intending to accelerate to 35mph and when the truck downshifted, the engine stalled, and I think the transmission tried to move to park. I got a notification of parking brake error on the dash and started hearing a ticking/clicking noise while still rolling, now down a hill. I moved the column shifter to neutral and it didn't do anything to stop the ticking. I pulled onto the shoulder and slowed down and, and as I neared stopping, the truck finished shifting into park and it jolted to a stop. I then saw a bunch of other errors like engine coolant too hot, stability control disabled, and forward collision warning disabled. There may have been others but I don't recall. The tachometer was frozen showing roughly 2000 rpm until I turned the key to off. Then the dash said to be careful exiting because the parking brake wasn't on. After turning the key to off, I restarted it, the lights on the dash cleared, and I was able to shift to drive, and make it home 3 min later. There are no lights on the dash, so I'm hoping this can still diagnosed at this point. The truck has 793 miles on it as it sits now. The soonest service appointment I have been able to make is for July 8th, but the dealer won't guarantee that it will be seen then.
