On June 20, 2025, my 2023 Toyota Tacoma (VIN [XXX] ed a sudden loss of effective braking during normal driving conditions (dry roadway, clear weather). The vehicle was being driven by my adult son. While slowing for a turn, the instrument cluster displayed a Pre-Collision System (PCS) malfunction warning and a Vehicle Stability Control (VSC) warning. The Driver applied the brake pedal continuously, but the vehicle did no decelerate as expected. ABS did not activate, and braking effectiveness was insufficient. During braking, the driver experienced reduced steering responsiveness. In order to avoid entering a busy roadway without adequate braking capability, the driver applied maximum steering input, fully loading the left side of the steering wheel with as much force as possible in an attempt to redirect the vehicle. Any reduction in speed occurred primarily due to the change in direction and tire to road friction, not effective braking. The vehicle was towed to a Toyota dealership. Dealer intake records document a PCS warning and no brakes upon arrival. Event Data Recorder (EDR/CDR) data shows continuous brake pedal application for approximately 5 seconds prior to the event, accelerator at 0%, and brake system hydraulic pressure reaching approximately 12.14 MPa (maximum recorded). Despite this, the vehicle did not stop as expected. No frontal crash pulse recorded. Toyota Motor North America later denied responsibility, asserting incorrect vehicle speed and stating that a CARFAX report indicated prior front-end damage. The CARFAX vehicle history report, dealer purchase disclosures, and service records show no reported accidents or damage. Toyota declined to provide brake system ECU logs (ABS/VSC/brake control modules). This incident raises concerns regarding a potential safety defect involving electronically controlled braking and its interaction with PCS stability control systems. Supporting documentation available. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5

Wiring harness on the vehicle is being completely replaced due to "rodent damage" according to the dealer. I am not an automotive engineer but if compromised wiring finally fails while driving I suspect a number of systems could be affected. There was no indication of this problem during vehicle operations. My insurance company agreed to pay for this about $7200. I have owned the vehicle for ten months.
