general problems of the 2025 Honda Odyssey

My 2025 Honda Odyssey has experienced an intermittent failure of the auto idle stop system on four separate occasions. While stopped at a traffic light, the auto idle stop system shuts the engine off as designed. When I release the brake pedal to proceed after the light turns green, the engine fails to restart automatically. Instead, the dashboard lights illuminate and flash, and the vehicle displays the message "press brake and start button. " pressing the start button once does not restart the engine. I have had to repeatedly press or hold the start button before the vehicle eventually restarts. During these events, the vehicle is completely disabled in active traffic and cannot be driven until it restarts. This has occurred four times, including while stopped at busy multi-lane intersections. The vehicle remained stationary after the traffic signal turned green while surrounding traffic expected it to move. This created a safety hazard because the vehicle unexpectedly became immobilized in an active traffic lane. I took the vehicle to an authorized Honda dealership. The service advisor acknowledged they are aware of similar complaints from other 2025 Odyssey owners but indicated Honda has not provided a definitive repair or service procedure. A diagnostic appointment has been scheduled. I have also found numerous reports from other 2025 Honda Odyssey owners describing the same auto idle stop failure. In many of those cases, dealerships ultimately replaced the starter under warranty after diagnosis. The consistency of these reports suggests this may not be an isolated incident. I am submitting this complaint because this is a safety issue. A vehicle that unexpectedly cannot move when traffic begins to flow creates a risk of a rear-end or other collision.

Vehicle shut off and put itself in park leaving a stop light. Was hard to restart.

Van completely shut down while in an intersection and the battery light came on. It was hard to restart. Took it to the dealership and they cannot find the problem.

The auto idle stop system on my 2025 Honda Odyssey fails to restart the engine when the brake pedal is released quickly after a full stop. When this occurs, the vehicle stalls completely in traffic and must be manually restarted by the driver. This has happened multiple times and is reproducible. The failed component is the auto idle stop/engine restart system. The vehicle is available for inspection. My safety and the safety of others has been put at risk multiple times because the vehicle stalled at traffic lights in active traffic, leaving me unable to accelerate through an intersection. The problem has been confirmed by Honda marysville dealership. The dealer stated they could not repair the issue and advised me to modify my driving behavior as a workaround. No repair was performed. The vehicle has been inspected by the selling dealership. A message appears during the failure telling me to restart the car. The problem first appeared within the first year of ownership on a brand new vehicle with basically zero miles at purchase. The cause appears to be a defect in the auto idle stop restart system that fails under specific braking conditions.
