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.”

“Pre-Collision Assist Not Available has been persistent since purchasing last month. There is 27 page thread (https://www.macheforum.com/site/threads/front-camera-fault-pre-collision-assist-not-available-errors.18710/page-25) recommending that we file a report here.”

“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.
