NHTSA Complaint #11707300 — 2025 HONDA PROLOGUE

On December 1, 2025, the 2025 Honda Prologue was pulling into a parking spot between two parked vehicles at low speed. While in forward gear, the Prologue experienced an unexpected acceleration event and collided with three parked vehicles, two of whom were hit with sufficient force to impact adjacent parked vehicles. The driver is unaware of having pressed down on the accelerator and is additionally concerned about why none of the vehicle safety features such as the equipped Collision Mitigation Braking System (CMBS) activated to prevent these collisions. The vehicle was brought to a local Honda dealership, yet they were unable to draw any conclusions regarding why the unexpected acceleration event occurred. The vehicle owner requested a DTC scan report and EDR (event data recording) data from the vehicle, and received the DTC report but not EDR data. The Honda dealership advised calling the American Honda customer service line with the case number to obtain EDR data. The customer service line was not able to assist because they were not able to identify the case manager, which points to a documentation error within Honda servicing processes.
