False collision warning 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, 2025, 2026.
What this problem usually is
This group is about the forward collision warning itself. Owners describe alarms with nothing ahead, a forward camera that fails or reports itself blocked, and other safety features shutting off at the same moment. A lot of them happen at highway speed, and a lot end with a dealer who couldn't reproduce it.
What got replaced
Owners who name the part that was replaced mention the forward camera (76 reports), the radar sensor (15 reports), the windshield (15 reports) and the software (12 reports).
Recalls and investigations
No recall on collision avoidance covers the 2018 model year as of Oct 2, 2026.
What owners paid
22 of the 115 reports quote a price. Each dot is one quote. The middle half runs $1,700 to $2,000.
When it happens
The middle half of failures fell between 33,000 and 90,000 miles, from the 13 reports that gave a mileage.
What owners wrote
“The front camera has failed so all of my forward driving safety features no longer work such as lane keep assist, adaptive cruise control and collision mitigation. Every time I turn on the engine I have multiple warning lights that appear every time that have to manually acknowledge to clear them from my dashboard.”

“The windshield-mounted front monocular camera (Honda Sensing unit) overheated and failed/burnt out. This failure completely disabled the Forward Collision Warning, Automatic Emergency Braking, Lane Departure Warning, Lane Keeping Assist, and Adaptive Cruise Control systems, triggering multiple safety system warning lights on the dashboard.”
Filed Aug 31, 2026
“ADAS front facing camera died at 104,716 miles. No prior warning. All ADAS systems are down. Five emergency warnings on starting up the car. Normal driving is OK, but safety systems are no longer working. Reported repair cost from Honda dealership is $2000+.”

Should you keep driving it?
This page can't tell you that. 3 of 115 reports involved a crash and 3 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.
