I posted this in 2016-2022 forum... I had this problem for years with our 2016 honda pilot and posted about it on this forum. Submitted multiple complaints about it to NHTSA and Honda beginning in 2017. I checked the NHTSA report on the investigation they've opened and my complaints are included in their report. Honda replaced the battery, stop/start button, starter motor assembly, etc. Nothing fixed the problem. Someone from NHTSA emailed a few times. Last time I heard from them was in fall 2019 but they told me they couldn't share what was going in in their research into the problem. Since it looked like no solution was in sight, we finally got rid of it for a new car. Will never buy Honda again. Given that people, including me, were complaining about this to Honda and NHTSA more than 5 years ago and they are just getting around to a "preliminary investigation" now doesn't give me confidence this will be resolved urgently, but maybe those of us who purchased this defective car can get some compensation. Totally agree that should file NHTSA complaint if still having this problem. Best to also take it into dealer so it can be documented.
