At a stop light and the car shifted to neutral and lost power, had to restart car. This happened twice, once on a busy road and we were almost rear-ended. Took the car to dealership they said the only thing they could find was that it needed a new battery. Changed battery and has not happened since. They said that likely the battery did not have enough power to power the auto stop/start feature so when I stopped the car lost power. I had no indication that the battery was low and never had a car with a low battery lose power in the middle of traffic. I feel like this is bad design and a potential safety hazard.

Problem with Auto idle stop mechanism. There was an event of no restart after the auto start/stop engaged. There have been several issues with it over time. For a while it cut out completely until we got a new car battery. Especially in the past 3 weeks the car has hesitated to start after a stop. Then, yesterday, [XXX] it failed to start creating a traffic hazard. We were at a red light and once green, I removed my foot from the brake and it would not start. Traffic was approaching behind us and it was a dangerous situation. It was stressful for me, the driver as well. After putting the car into several gears and pressing the start button twice, it eventually started. A display messages appeared only when the car would not start. I believe it said to put the car into neutral. If the car failed to start, it would have been stuck at a major intersection posing danger to ourselves and fellow drivers. Previously, when the feature stopped working, we reported the issue to our local Honda dealer and they did not offer a solution but said there are a number of factors that could cause it to not operate. We didn't mind it wasn't working because we loathe it. Later we purchased a new battery and it started working again. Also previous to [XXX], we updated the software system. We were aware that there was an update for this issue. To ensure we have the update, I checked it again, today, 8-10-2025 and our software was up to date. We (my wife and I) were so alarmed by yesterday's operation failure that we are considering getting rid of the vehicle. However, we don't want to pass the problem onto someone else. We are petitioning that this become a bulletin or recall fully covered by Honda. We see that similar 2016 to 2021 vehicles are under a bulletin. Honda is aware of the issue since 2016. 2022 Honda Pilot should be included. The software update did not resolve the issue. Please escalate from investigation phase to a mandatory Honda fix. TY!
