2019 Nissan Rogue cruise control problems

Tl* the contact owned a 2019 nissan rogue. While the brake pedal was depressed at a fuel station, the engine revved independently. As the engine revved, the vehicle accelerated forward independently and crashed into a parked vehicle and a building. It was discovered that the vehicle was traveling 56 MPH when the failure occurred. The all wheel drive error and malfunction warning indicators flashed across the instrument panel after the crash. The air bags did not deploy.

I was driving at I-80 westbound from council bluffs to omaha. Just after entering in omaha my nissan rogue sl suddenly slowed down its speed from 65miles to 40 miles for no obvious reason. I had my pro pilot assist function on at it seems that the car decided for no reason to decrease the speed as there was no vehicle in the front of the car that I could have seen in my lane. I was worried and got panicked as there was a semi truck behind me.
