2024 Honda Odyssey ELECTRICAL SYSTEM,ENGINE

The contact owns a 2024 Honda Odyssey. The contact stated that while stopped and using the Auto START/STOP feature, the vehicle failed to restart as designed. While attempting to restart the vehicle, the battery warning light flashed on the instrument panel. The vehicle restarted after several minutes. The vehicle was not diagnosed or repaired. The manufacturer was not notified of the failure. The failure mileage was approximately 41,000.

The 2024 Honda Odyssey has an idle-stop feature which is hesitating too much and risking stalling at intersections. Honda tried to blame it on the battery but even Honda has tested the battery as fine. The 2025 model has a software fix to disable the idle-stop when the AC is running hard and this would fix the 2024 but they claim to have to fix for the car. This is dangerous to be stalling at major intersections and many Honda and Acura vehicles have had and many still have this problem. Remembering to disable the control every time one starts the car is NOT a fix. Please help get this problem for 2024 Honda Odyssey’s fixed before someone gets injured or worse trying to restart a car when it keeps stalling

With the auto cutoff engaged when stopped at a red light, the vehicle shut off on its own. I had to put the vehicle in park and try the push button start a few times before the vehicle turned back on. I had to put my flashers on because the light turned green before I could get it restarted. Someone had to swerve to avoid me. I was almost rear ended because the intersection I was stopped at was near an interstate offramp and the driver did not recognize I was stopped. I took it to a Honda Dealership and they said they could not replicate the problem but that there was a bulletin identifying the issue and that the bulletin had been withdrawn. I was told that it likely meant a recall would be coming in the future. The following message came on when the vehicle turned off: Shift to park. The red battery dash light was on.

While operating the vehicle, I have experienced repeated problems with the idle stop/start system. Specifically: 1-The engine automatically shuts off at stop signs and stop lights as designed, but at times the vehicle fails to restart immediately when the brake is released or the acceleration is pressed. 2-Multiple occasion while stopped in traffic the vehicle unexpectantly shifted into "Park." 3-For the last 3 weeks the vehicle sometimes hesitates to start on first attempt.

For a fourth time this year, the vehicle suddenly loses power while travelling on the freeway. It completely shuts off acceleration for 30-60 seconds and then picks back up by itself. The last two ocassions it happened was between 8:10 am and 8:12 am on August 18,2025. It happened on the freeway again on August 22 at about 8:13 am. I fear for my safety and life driving on the freeway
