   2025 Honda Odyssey. The auto idle-stop shuts the engine off at red lights as designed, but the engine intermittently fails to restart when the brake is released. Some days it happens, some days it does not; on occasion twice in one day. Restarting requires pressing the start button repeatedly. No warning lights appear before or during the failure. The vehicle is left stalled in active intersections when the light turns green, creating a risk of rear-end collision. The issue…

   I purchased a brand-new 2025 Honda Odyssey in June 2024. The vehicle currently has approximately 18,000 miles. The Auto Idle Stop system has repeatedly shut the engine off at traffic lights and failed to restart it. When this occurs, the engine does not crank, the dashboard remains illuminated, the radio and other accessories shut down, and the display instructs the driver to press the brake to start the engine. Pressing the brake and attempting to restart the vehicle does…

   My Honda Odyssey shuts the engine off at a stop under Auto Idle Stop and then fails to restart when I release the brake. I have to shift to Park and press the start button. This has happened at least 5 times, including today, while stopped at a traffic light at a busy intersection. The van was immobilized in active traffic. Extremely dangerous situation.

   Auto Idle Stop feature wouldn't restart vehicle while at an intersection. The vehicle eventually restarted, but not without causing traffic disruption. It took the entire light cycle(red-> green -> red) for my wife to be able to manually(had to push the start button several times) for the car to eventually restart. Warning light on dash said something to the effect of "unable to engage "something"(wife cannot remember, she was panicking due to being stalled in the middle of…

   The car stalls out/does not start back up when Idle Stop is used. This causes a risk for an accident as the vehicle does not more forward when it should. This now happens daily for the past month. This happened in the past with this same vehicle and the starter was replaced by the Honda Dealership Service Department. It is going into the Honda dealership Service Department on 10/5/2026.

   My 2025 Honda Odyssey Elite has recurring, intermittent difficulty restarting after the Auto Idle Stop system shuts the engine off at a stop. I purchased the vehicle in December 2024, and it currently has approximately 37,000 miles. When attempting to restart, the engine sounds as though it is struggling to turn over. Most of the time it eventually restarts automatically, but on some occasions it fails to restart automatically and I must use the ENGINE START/STOP button. An…

   My car has stalled numerous times when it stops, and the engine goes into the fuel saving off mode. It stalls when I try to drive away as my foot comes off the brake. This has happened more times than I can count. In addition, as a side not I rented another 2025 Honda odyssey, and it also died when trying to go. The dealer has supposedly driven my vehicle when we bring it in but never has reproduced it according to them. They did admit that they knew about it but had no…

    Several (more than 5) times over the past 2 months my car has had the same issue occur. The automatic Idle Stop feature was turned on and the engine was idling at a stop sign or red light. When I went to press on the gas to begin driving again, my engine would not restart and I received an error message. I was unable to change gears and had to manually turn off my engine, wait a few seconds and restart the engine, and then put back into drive. Again, this has happened…
