2020 Toyota Highlander engine problems

In my 2020 Highlander I approached a stop sign at a "T" intersection behind 4 other cars. After stopping and looking to see road was clear of oncoming traffic, I pulled out and started my left turn. As I was turning into my lane the car engine turned OFF and the steering wheel was LOCKED in the left position. There was no power for the brakes, which left me jamming on the brake pedal as hard as I could only slowing the car slightly.

The contact owns a 2020 Toyota Highlander. The contact stated that while the vehicle was idling or parked, the engine would suddenly seize. The failure occurred intermittently. The check engine warning light illuminated with a message that the brakes were enabled. The contact restarted the vehicle several times before the vehicle operated as needed. The vehicle had been taken to the dealer 3 times however, the dealer was unable to diagnose the vehicle. The vehicle was not repaired.
