Warning lights on other Accord years
Report counts are for each model year on its own, so a newer car has had less time to collect them. Model years with too few reports of it for a sheet: 2016, 2017, 2021, 2022, 2023, 2024, 2025, 2026.
What this problem usually is
This sheet is for the moment the whole dash lights up at once: a string of warnings for systems that seem to have nothing to do with each other. Sometimes features drop out. Sometimes it's all gone on the next start. When that many systems complain together, it makes sense to look first at what they have in common.
What got replaced
Owners who name the part that was replaced mention the battery (5 reports) and the sensor (3 reports).
Recalls and investigations
One recall on the electrical system covers the 2020 model year. A recall on the same system isn't always the same failure, so read the defect text.
A software error may cause intermittent or continuous disruptions in communication between the Body Control Module (BCM) and other components.

Should you keep driving it?
This page can't tell you that. 1 of 33 reports involved a crash and 1 people were hurt. Owners who file are the ones who had a bad experience, and nobody checks their reports. If the problem affects steering, braking, power or a fire risk, treat it as a safety fault and have it inspected before a long or high-speed drive.
File your own report with NHTSA. Complaint counts are how a problem gets an investigation. How reports land on this sheet.
