“The contact owns a 2023 Toyota Highlander Hybrid. The contact stated that while depressing the brake pedal, there was a hesitation, and the vehicle surged forward before coming to a stop. There were no warning lights illuminated. The contact became aware of TSB 0059/23, NHTSA ID Number: 10244133 (Electrical System, Air Bags, Service Brakes) for the 2021 - 2022 Toyota Highlander.
