Radar blocked by the lightest snow flurry ever

Ahahahah. Nice one! Burn. Damn, you got me. There must not be much going on over in Orwigsburg today.

I agree the warning pop-up (that returns as soon as you dismiss it), is super annoying and distracting. You have to go into the menus (while it keeps popping up) to disable the safety feature requiring the front radar if you want the warning to go away. And messing with menus is a hazard in itself while driving. Not ideal. I would love a button to press for when it's snowing (pretty common occurrence where I live) to turn off the safety features needing front radar. One more button for when I use my hitch bike rack to turn off the relevant rear sensors. Those would be great quality of life buttons.

Happened to me yesterday on the Mass Pike. While I dont have a problem with the truck stopping functions based on sensor contamination, what drove me crazy was the warning message that keeps popping up every 8 seconds (Yes I timed it) to tell me functions are not working. Tell me once and just display a little icon.

OP - same up here in N. Va. Cleared the front grill area but still had sensor annoyingly beep when stopped about object in front of right front sensor. First time so like the rear brake when bike rack attached to tow hitch, got to adjust the warnings.

Can confirm it is very, very annoying. Also noted the headlights can freeze over and don’t appear to get warm enough to melt ice formed on them.

My worry is the radar system is linked to the emergency braking control, so a sudden covering of it makes the car nail the brakes.
Is this a possibility?

It’s the parking sensors. Radar didn’t give me an error so unsure.

It’s any modern car with sensors. My Cayenne does it, as does my wife’s Macan. Those are even more touchy. Best you can do is use a snow brush or knock if off I reckon.

works fine if you get a storm during the night and it passes thru.

different story when you are driving down the road/highway and it cakes up on the sensors. this is the most annoying part from slush, heavy snowfall or snow melting from the hood onto the sensors and freezing.

i just normally drive w/o radar CC and just use the normal constant cruise control. also i have most of the nannies turned off or turned down to the lowest distance setting.

not possible. the system knows something is blocking because the reflection
is on the sensor itself. that and it doesn't change distance

Yup, it is possible. We had an ice storm overnight the other day and the next morning my truck front sensor were covered by ice and all bells and whistles went off when I was trying to move forward and the truck slammed on the brakes pretty hard, very annoying. It seems that the sensors can’t make the difference between ice covering them and a real obstacle.
