Engine Noise problems of the 2020 Ford Explorer

This particular problem has occurred on more than one occasion, most recently today (January 30, 2021). While driving and then accelerating, the car sputtered and almost died. We were pulling into oncoming traffic and needed to accelerate. We pushed on the accelerator and the car made a sound as if it would speed up, instead it stalled. (a message flashed on the screen, but it was too quick for me to read. ) we were almost hit by a car before we were able to pull into a parking lot. We turned off the car and drove around for a few minutes. We went to pull back out onto the street and accelerate when it sputtered and stalled. We turned the car off and sat. We were lucky we were not on a highway or busier street.

Steering wheel shakes and engine sounds as it is going to stall at speeds between, 35 and 45 mph. Ford had vehicle for two weeks total and confirmed issues. They did not know how tp fix. They said vehicle is within specifications'.

2020 Ford Explorer st with approximately 1,927 miles. I started the vehicle and put it into drive and it started to roll forward even though my foot was on the brake. Regardless of how hard I pushed the brake, the car continued to inch forward until I fully depressed/repressed the brake. I shut off the vehicle, waited a few minutes, and attempted to restart. Upon the attempted restart, all lights on the dashboard began flashing and the engine failed to turnover. The in-dash display then began beeping, flashing service/hazard/warning indicators, and cycling through the following error messages: -park brake fault service now; -pre-collision assist not available; -service advancetrac; -driver door ajar; -steering assist fault service required; -check park aid; -see manual; -front camera fault service required; -full accessory power active; I turned off the vehicle and attempted a few more restarts ranging in intervals from an immediate start/stop, 1 minute, 5 minutes, and 10 minutes without success (same error messages displayed as described above). There were also no alert messages/notification in the Fordpass mobile app indicating the above failures. My next attempt was a few hours later and the vehicle started without error, but did not give any indication that the vehicle had failed to start the previous time. I stopped/restarted the vehicle again without error and put it into reverse and then drive and there did not appear to be any failure of the brake pedal. I took the vehicle for a test drive around my neighborhood and noticed that 1st and 2nd gear appeared to shift just fine, 3rd gear made a loud grinding/vibrating noise and took longer to shift than normal, and then the vehicle did a hard shift into 4th gear. I only got up to about 35 miles per hour, but the vehicle never shifted out of 4th gear, but appeared to hold the rpms higher than normal.
