Driver assist on other Model Y 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: 2025.
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 software (16 reports) and the camera (3 reports).

What owners wrote
“Lane departure pulls the car unsafely when two lanes merge or one lane splits. It has caused us to swerve a few times leading to major safety concerns. It's locked by software we are forced to turn off manually every time we drive. Even when off it seems to pull me around on certain roads”

“Adaptive cruise control slams on the brakes at highway speed alleging âcurvature assistâ on flat, straight roads. Dealer replaced firmware and problem persists. Defect appears to be inherent to adaptive cruise control”

“FSD was unable to avoid object in road, may be due to how the adaptive headlights work as I was unable to see the object as well FSD/adaptive headlights may may it hard or impossible to see objects on road at night No In the process of a insurance claim No”

Should you keep driving it?
This page can't tell you that. 2 of 34 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.
