Warning lights on other Odyssey 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: 2014, 2015, 2016, 2021, 2022, 2023, 2024, 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 (8 reports), the module (4 reports) and the sensor (3 reports).
Recalls and investigations
One recall on the electrical system covers the 2018 model year. A recall on the same system isn't always the same failure, so read the defect text.
The wire harness for the third row seat accessory power outlet may get pinched between the unibody and rear trim panel, possibly damaging the wires and causing an electrical short.

What owners wrote
“The front facing camera has stopped working. Anytime we turn the vehicle on we get multiple warning lights (lane assist, cruise control, bright lights, braking, etc) aren't working.”

“The Foward Looking Camera is failing and causing all the ADAS not to work and has all the lights on the dash. The code comes back as U3000-49 which is a multi purpose camera failure.”
Filed Sep 6, 2025
“Front camera failure causes multiple safety issues. Lane keep assist collision mitigation road departure mitigation high beam problem This is a known issue and the dealership knew about this immediately hearing the multiple warning signs. Cost of replacement is over $2000.”
Filed Jul 12, 2025
“Multiple dash lights warnings (LKAS, forward collision, lane departure, etc.) came up. Brought it to the dealership and was told that this is an electrical camera issue that is overheating, and there is no preventative or ways to keep it from happening. It would cost an upward of $2000 to fix it. This should be part of the recall since it seems like itâs happened quite frequently with the other Honda Odyssey.”

Should you keep driving it?
This page can't tell you that. 0 of 33 reports involved a crash. 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.
