Driver assist 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
These reports come from drivers whose assistance systems did something they didn't ask for. Adaptive cruise switches itself off, or brakes for a car that isn't there. Lane keeping tugs the wheel toward the line, or a "sensor blocked" message appears on a clear day. Because both systems can brake or steer, owners tend to file them as safety complaints, and NHTSA files them under speed control, lane departure or forward collision.
What got replaced
Owners who name the part that was replaced mention the camera (90 reports), the software (17 reports) and the radar (8 reports).
Recalls and investigations
No recall on collision avoidance covers the 2020 model year as of Oct 2, 2026.
What owners paid
44 of the 120 reports quote a price. Each dot is one quote. The middle half runs $1,400 to $2,060.
When it happens
The middle half of failures fell between 37,000 and 76,000 miles, from the 19 reports that gave a mileage.

“All warning lights came on for Adaptive Cruise Control, Automatic Emergency Braking, Forward Collision Warning, Lane Departure Warning, and Lane Keeping Assistance.Based on my research, it seems the forward facing camera has failed. The vehicle only has 37,000 miles on it and it is only 5 years old.”

“Out of nowhere I got a bunch of errors involving the addaptive cruise, lane keep assist, auto highbeams, collision avoidance, and the brake system light came on. the van has under 40K miles on it. From a quick search I can see that this is a VERY common issue.”

“The design defect of the camera in front of the car seriously affects the life safety of the driver. The dealer did not pay attention to this problem. The car did not collide, but six error prompts appeared during driving: Adaptive Cruise Control Problem, Lane Keeping Assist Problem, Collision Mitigation System Problem, Road Departure Mitigation System Problem, Auto High-Beam Problem.”

Should you keep driving it?
This page can't tell you that. 0 of 120 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.
