2023 Subaru Outback electrical system problems

My son was traveling at an appropriate highway speed when the truck in front of him stopped suddenly. He braked immediately and was able to slow down significantly, but not enough to avoid colliding with the back of the truck in front of him. He was going approximately 20 mph, still braking, when the collision occurred. His best recollection is that the vehicle's pre-collision system did not engage until after he collided with the truck. There was damage to the front end of the vehicle but it was not severe.

The contact owns a 2023 Subaru Outback. The contact stated that upon purchasing the vehicle from the dealer on October 3, 2022, he noticed that the automatic collision alert to the Emergency Services, the diagnostic alert, the remote services, the SOS emergency alert, the stolen vehicle recovery alert, the Roadside Assistance alert, and the multimedia features were inoperable.
