NHTSA Complaint #11711180 — 2025 HONDA PROLOGUE

Vehicle: 2025 Honda Prologue Location: Sacramento, California Date of Incident: [XXX] What failed or malfunctioned The vehicle experienced a sudden loss of directional stability involving the steering system, brake-by-wire system, and electronic stability control (ESC). Steering and braking inputs did not produce proportional vehicle response. What happened While driving under normal conditions, the vehicle began drifting to the left. I attempted to steer back to the right and applied braking; however, the vehicle did not respond as expected. Electronic stability control did not appear to engage or correct the loss of control. The vehicle then deviated from its intended path, overturned, and struck a fence. The vehicle was declared a total loss. No other vehicles were involved, and no injuries occurred. Safety risk This failure created an immediate and serious safety risk. The loss of steering and braking effectiveness could have resulted in severe injury or fatality. The rollover demonstrates a critical safety concern. Warning signs No warning lights, messages, or symptoms were present prior to the failure. The event occurred suddenly without notice. Inspections The vehicle was inspected by police and insurance representatives. The manufacturer has not yet inspected the vehicle. The vehicle remains available for inspection through the insurance provider. Dealer confirmation The issue has not yet been reproduced due to the vehicle being totaled. Additional concerns The vehicle’s behavior was inconsistent with normal operation of safety-critical systems designed to maintain vehicle control. I am concerned about system performance, calibration, or possible electronic control failure. Manufacturer contact I reported this issue to Honda Customer Care by phone and requested escalation to engineering review.
