2026 Honda Prologue

On August 23, 2026, I was backing my 2026 Honda Prologue Touring out of a parking space at a Costco parking lot in Cedar Park. I was reversing very slowly, at below walking speed, and repeatedly applying light brake pressure because of interruptions and pedestrian traffic in the lot. While reversing in this manner, the vehicle abruptly and forcefully applied the brakes on its own. The braking was violent enough that I initially believed I had struck an object. There was no vehicle, pedestrian, cart, or obstacle behind me, and no vehicle was crossing behind me from either direction. Conditions were daylight, warm and dry. The electric parking brake did not engage, and no warning message or fault light appeared before, during, or after the event. The vehicle operated normally afterward. An unexpected hard stop while reversing risks injury to occupants and creates a risk of being struck by a following or crossing vehicle. This is one of two uncommanded braking events on this vehicle; I am filing a separate complaint regarding a forward automatic braking event. Mileage at time of incident: approximately 1,600. The vehicle has no open recalls and has not yet been inspected by a dealer.
