2023 Honda CR-V brakes problems

I was pulling up to the Subway sandwich shop to pick up my lunch. I was approaching from their back ally (coming from Walgreens next door) so I could not have been going faster than a few miles per hour. As I approached the parking space the car started speeding up so I turned right to keep from going through the building and drove in circles to keep from hitting the buildings. I could not go onto the street because traffic was heavy.

The contact owned a 2023 Honda CR-V Hybrid. The contact stated that while her husband was driving 50 MPH, the vehicle in front slowed down, the brake pedal was depressed but traveled down to the floorboard, but the vehicle failed to respond and rear-ended the vehicle in front. The contact stated that the vehicle bounced and spun around, facing incoming traffic. The contact was unsure whether there was a warning light illuminated. The contact was unsure if any other vehicle had crashed into his vehicle.
