Vehicle was running but transmission was in park. Suddenly on screen in front of driver this message appeared: brake system failure 43mph top speed warning service esc. Vehicle was not moving. Engine was running but vehicle was in park. I had to drive it home. Very difficult to stop. Brake pedal vibrated violently. Very long stopping distance even at 20mph. I had the vehicle towed to the dealership from which I had purchased it. I bought this vehicle on 25 Nov 2024. Right now its mileage is 3757. Obviously my safety and that of others was put at risk. The service department at the dealership has not communicated with me at this time. There was no prior warning nor were there any prior symptoms of this problem. It occurred very suddenly.
