Not sure about which component failed and put my family and I in significant danger. We had just come to a stop at a traffic light at the end of a highway exit ramp when the car shut off without warning. Completely off. Hazard lights didn't even work. Nothing worked. Took a minute or two until the vehicle restarted as if nothing had happened. Cars were coming up fast behind us and had to move quickly to get around us. This was late at night so we were hard to spot without any working lights. Thank the Lord no one was injured. I suspect it has something to do with the idle-stop feature. This incident happened within the last 2 hours so it hasn't been reproduced or confirmed by a service center. Please require Honda into issue a recall for whatever caused this defect.

At a stop light the engine idle shutoff feature shut off the engine. Then a few moments later the entire vehicle shut off. I could not turn the vehicle back on after trying several times to do so. After about five attempts the vehicle turned back on in park gear. During this time the light turned green and the vehicle would not turn on, cars behind began honking. This has happened a few times since owning the vehicle. I was dead in the middle of a busy intersection. I have asked the dealer to look at the electrical system as there have been several anomalies but it checks out fine. I replaced the battery thinking that might be the problem but did not work. I believe it is the same problem as PE22005

Our Odyssey is equipped with idle stop. Sometimes when idle stop engages, the engine won't start again afterwards. We need to turn the car off completely, and then try again. Usually it turns on after doing so. We try to always turn off the idle stop when we start up the vehicle, but sometimes forget. This hasn't led to an accident yet, but has led to some angry vehicles when we can't move when a traffic light turns green. To be clear, this was not an isolated incident, but happens somewhat regularly if idle stop isn't turned off. Honda dealers have told us they don't have any fix, and have recommended that we could purchase a third party "idlestopper".

My Vehicle was at the dealer for service in March of 2025. At that time they performed RECALL 23-008 although the vehicle did not have issues with the idle stop system. Since some time in June, at multiple occasions, the vehicle shifted to Park on its own when restarting from idle stop. Last night, the vehicle fully shut off and lost all electrical power when restarting from idle stop leaving me stranded in the dark at a busy intersection without the ability to turn on my hazard lights. The vehicle repowered after a few minutes. When the system restarted, the info-tainment system activated the anti theft software which happens during full power loss.

On at least 5 occasions the car has not restarted after going into auto idle while stopped. Normally after pressing the brake pedal all the way down while stopped, the engine will shut off and then restart after releasing pressure from the brake pedal. When it doesn't restart, all the lights on the dashboard come on and you can't do anything. It won't restart if your press the start button and you can't shift it to neutral to push it out of the road. Eventually it will restart by pressing the start button. I have not had this problem if I turn off the auto idle, however you have to manually turn off the auto idle every time you restart the car.

The car stalled when stopped at a red traffic light. This happened on 2 occasions, 11-3-23 and 12-9-23. The second time other cars behind us had to go around us while we tried to restart the car which put them at risk of being hit by cars in the other lanes. There was no warning. I took the car in for regular maintenance a few days ago during which the dealership did a multi point inspection but did not discuss this issue. Yesterday I heard about the fuel pump recall and think this might be the same issue. I called the dealership today but they said our car is not under the recall. Our car is available for inspection upon request.
