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 owners wrote

“The forward camera on this vehicle fails and you lose all your adaptive cruise control, regular cruise control, Lane assist, emergency breaking, and adaptive high beams. This is the second failure of the camera since I have owned the vehicle 1.5 years and 30000 miles.”

“All warning lights related to the Honda Sensing driver assist features come on and the assist features are inoperative. Vehicle still drives fine but even normal cruise control is no longer an option. Some warning notifications pop back up while driving even after dismissed which is rather distracting.”

“All of the advanced driver assistance systems have failed: adaptive cruise control, emergency braking, forward collision warning, lane departure warning, lane keeping assistance. Additionally, there is a brake failure fault. The Honda dealership said that the plastic cover over the radar is prone to fogging and that we should clean it. We tried that and it did not work. Still get all of the faults and warnings.”

Should you keep driving it?

This page can't tell you that. 1 of 121 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.
