While driving on the highway multiple vehicle dash lights began flashing, including brake system, tire pressure, check engine; and the vehicle suddenly and completely lost the ability to accelerate. The car was clearly still on and in drive, but pressing the gas pedal had no effect. After turning off the car and restarting after a few minutes, the brake system alert persists. Car was towed to dealer out of concern for safety. The attached picture is after the vehicle restarted.
