2022 Nissan Sentra electrical system problems

I was told that the throttle malfunctioned. I was driving on the highway and the car would not accelerate, the dash said malfunctioning and the cars driving beside me had to swerve around me. I took the car back to the dealership where I purchased it and was told that parts had to be ordered and that it was a throttle malfunction. The car has not been inspected by anyone except those at the Nissan dealership where it was purchased. There were no warning signs before the malfunction.

The contact's son owns a 2022 Nissan Sentra. The contact stated while driving at various speeds at night, the front headlights were independently turning off. The contact had to pull over and turn off and turn on the headlight switch several times before the lights turned on. Additionally, the contact stated that her son stated that the Forward Collision Avoidance, and the back-up sensors were also turning off independently.
