False collision warning on other Mustang Mach-E years
No other Mustang Mach-E model year has enough reports of false collision warning for a sheet of its own. See every Mustang Mach-E year.
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 (58 reports), the software (14 reports), the radar sensor (4 reports) and the windshield (4 reports).
Recalls and investigations
No recall on collision avoidance covers the 2021 model year as of Oct 2, 2026.
What owners paid
7 of the 81 reports quote a price. Each dot is one quote. The middle half runs $786 to $7,000.
When it happens
Too few of these reports state a mileage to give a range.
What owners wrote
“Front camera stopped working after a long period of working intermittently (started to happen after passing warranty at 30,000 miles). Without that camera many safety features are disabled, like a front collision warning, lane departure, cruise control with adoptive speed, emergency breaking. The cable and processor issue was confirmed by Ford dealership service.”

“I have had a camera fault error for several weeks. This leads to the pre-collision assist and other features not being available. The camera module has already been replaced once and I still have the same problem.”

Should you keep driving it?
This page can't tell you that. 1 of 81 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.
