False collision warning on other Model 3 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: 2019, 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 software (4 reports).
Recalls and investigations
No recall on collision avoidance covers the 2023 model year as of Oct 2, 2026.
When it happens
Too few of these reports state a mileage to give a range.

Should you keep driving it?
This page can't tell you that. 8 of 31 reports involved a crash and 2 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.
