Oh boy, freaked out when I saw the brake warning light in the highway. I am guessing there is nothing I can do to avoid this.

It's either the camera opening on the windshield or the front emblem with the sensors inside that's covered in dirt/slush/snow. Essentially saying that it can't help you with its advanced guidance. Next time you clear off the windshield where the camera is - or the front emblem - you'll be all set.....

 

The windshield is frozen and covered in ice. When it melts, all will be good.

 

I had the same thing happen on my 11 MDX Adv with slushy snow that covered the plastic cover for the radar. A quick wipe and back to normal. I keep a cloth and windex wipes in the back now for the winter months.

 

I had that on my 12MDX Advance. Once when the sensor was covered with dirt and mud and the other time as an indication that my Alternator was on its way out. I'm sure your alternator isn't on its way out,
