I have the surround option. Today there was the first significant snowfall. I took a short drive to the mall -- everything was fine. On the way home, I started getting red flashes and audible warnings from the front sensors. I was really concerned it would set off the automatic brake. No cars were near me, and I was at least 100 feet behind other cars (and sometimes no one in front of me.) Most of the time it was the center sensor segment lighting; a few times the right side.

When I got home I found frozen drips over the bumper sensors (I had cleared the hood; apparently the snow falling on the hood after I parked melted and ran down over the sensors.

I can check on this before I drive, but in an icy storm this might happen en route.

Any else have this issue?

Yes, today in NYC the sensors kept going off when no one was in front of our car

We experience this during our first significant snowfall a few weeks ago in NE Ohio. It was only happening when stopped or at low speeds which I figured out was the Parksense feature and not the forward collision warning. My wife called me rather annoyed at the constant beeping and I first had her disable the forward collision and the warnings persisted. Once I had her disable Parksense everything quieted down. Fortunately Parksense is a physical button and much easier to turn on and off than FCW.

Yeah, I've had the issue with the Parksense sensors when ice and snow was on them, but I haven't had it happen with the Forward Collision Warning. After the Parksense alert sounded a few times, it popped up a message that said "Parksense disabled. Please clean sensors" or something to that effect.

Plus, if I am not mistaken, the Forward Collision Warning uses both the radar emitter in the front center of the lower grill and the forward facing camera, not the proximity sensors on the bumper.

Correct, the proximity sensors are shorter range and only work at slow speeds.
