The contact owns a 2021 Toyota Sienna Hybrid. The contact stated that while depressing the brake pedal, there was a three-second delay before the brakes would respond. Additionally, the brake pedal was difficult to depress, creating an extended stopping distance. The vehicle was taken to the local dealer who adjusted the brake stroke sensor and recalibrated the braking system; however, the failure persisted.
