2013 Ford Escape Titanium - Sensors and Alerts Stopped Beeping... Can I Leave It Like This?

I have a 2013 Ford Escape Titanium, and recently, the sensors and alerts that usually beep and flash when a car or person is nearby have stopped working. I actually kind of like the silence, but is it safe to leave it as is? Or should I get it checked out?

Check the sensors on your bumpers. They might be covered in dirt, which can mess with the system.

I did get a ‘BLIS sensor service’ message on the dash, and then it stopped beeping altogether.

Try washing your car. Sometimes that’s all it takes to clear up sensor issues.

Just bought it used about a month and a half ago, so not sure if this was already an issue.

Quick question—how do I start a new thread? I need advice about fitting an ’07 moonroof on an ’09 Escape. I can handle the wiring, but I’m not sure if the tracks and mounting holes will match up.
