2025 Toyota Grand Highlander Hybrid AWD, with about 16000 miles. While driving, the brakes failed. The brakes would only work if the pedal was pushed all the way to the floor. A "Low Brake Power" warning light came on the dash. The following warnings came on at the same time. Parking Brake System, Advanced Ultrasonic Detection, Vehicle Stability Control, Check Engine, Smart Stop System, Brake System, Electronically controlled Brake, Secondary Collision Brake, Anti-lock Brake System. I was lucky to have been traveling on a road that was not busy and was traveling at less than 30 mph very close to my home. Had I been driving on the interstate, on a busy road, or near pedestrians, the event could have injured or killed myself, my family, or others. The car was towed into the dealership. The dealership said that the issue was not current and the car operated normally when after it was towed in. The following DTC codes where present (P05E000, P05E062). This indicates an issue in wiring or brake pedal stroke sensor. They suspect its an intermittent issue with the sensor. The sensor was replaced (P/N, 89510-0R010 and 62112-0E040-C1). They also said the car battery was low and replaced it (P/N 00544-H5061-540). The dealership said that they would send the affected part to Toyota for inspection, but I have not heard anything back. The dealership experience was poor (Mark Jacobson Toyota, Durham, NC).
