I know this is an old thread… but.

I just picked up my 2024 Crosstrek Limited.
The eyesight cameras (all three) are encased in a black plastic shroud.
You can not see anything from inside, though you can see the lenses from outside.
I guess this protects the lenses from Windex and fingerprints.
There is also a large oddly shaped black area on the windshield. It‘s purpose may to shade the camera lenses from the sun? It is not as large as the gray windshield “no go zone” in the manual.

Anyway: Does anyone have a renewed opinion of the windshield no-go zone?

Now that the cameras are pretty much completely boxed in, you can’t really violate their views from inside.
Does the gray box rule the day for my dashcam install? Or will I be ok inside the gray, but outside the shroud?

If you haven't already done so, read the manual...especially the Eyesight guide. After that, when in doubt, test it out! Case in point - After reading my 2019 Eyesight booklet about not using Certain fluid in my windshield washer, I decided to go ahead and test using Rainex washer fluid, and in 4 years have never had a single glitch or problem that I'm aware of.

As mentioned, read your owner's manual about Eyesight and placing dash cams and EZ-Pass transponders anywhere near. Subaru warns against placing electronics near Eyesight so that's your first clue. If you choose to ignore warnings and Eyesight fails, there are only three reasons; aftermarket electronics interfering with Eyesight, inside/outside obscuration of cameras or outright Eyesight failure. You can experiment with temporary setups to see if interference occurs before a semi permanent installation but beware of environmental conditions triggering Eyesight failure with an error message and indicator; in addition to what's already mentioned, interior window fogging can occur to disrupt Eyesight.

My new Crosstrek Sport, since July, has triggered Eyesight errors. Each occurrence were brief. After reading issues about Eyesight in previous models, my Eyesight errors in my estimation, are attributed to inside fogging on warm humid days I didn't want ac and used blower speed for ventilation with windows closed. As soon as Eyesight triggered an error message with yellow symbol, I guessed humidity and either turned on ac or raised blower speed set for defrost to move airflow onto the windshield. No visible fogging was seen in every occurrence. Eyesight returned in a few blocks of local driving. The Eyesight covers do not completely seal against moisture intrusion into cameras as they're more for protection against interior damage from cleaning and maintenance. My concern, in NYC weather, is if Eyesight drops out more as temps drop and snow occurs as humidity goes up. Several rain days did not stop Eyesight, one or two days were pouring with wipers trying to keep the windshield clear for local driving. I usually have blower on for ventilation with windows closed to enjoy quiet driving and/or listening to music. In hot summer heat, ac was always on and I assume interior fogging is a non issue affecting Eyesight.

After a cold night, I imagine that the (glass?) lenses of the cameras are nice and cold And fog up. Even with the defroster on, they might take longer to defrost than the windshield.

AK:
I will be watching this thread with interest, thanks.
I had my first encounter with eyesight shutting off when I was driving in a light rain and then a deluge hit. Even though I cycled my WSW to high the rain was too much and the eyesight system shut down and several warning lights on the dash lit up. After the 'hard' rain had passed the eyesight system resumed normalcy after about 5-10 seconds.

I was pretty alarmed when it happened as I thought something had broken on the eyesight system, but apparently it worked as it was designed. Just shut down, let you know about it and when conditions allowed, it came back on.
Huh, who knew!

That's why when I got my 2019 I read every word in the main user's manual and the Eyesighte booklet and it warned me of those things that might cause it to shut off. That way I wasn't shocked when **** happened LOL. For the most part, the only time man has shut off briefly is when I'm going through road construction areas where it can't see a right side lane marker or the center lane markers.

Everywhere isn't free of overnight condensation along with temperature drops. going off script for a moment, temperature dewpoints vary around the country so fogging may be more likely to occur in some regions than others. I would presume Subaru engineers had this thought out in advance with real world testing to determine acceptable design without becoming annoying with owners calling/visiting/emailing SOA for comments. While I cannot prove interior fogging occurred in my Sport (no visible fogging seen) to trigger Eyesight fault, the return of Eyesight function after any combination of increasing blower speed, ac use or defrost mode, seems to verify my suspicions as opposed to actual intermittent failure that would encourage me to visit to my dealer while my Sport is under warranty.

Dew point temperature is a function of temperature and relative humidity, not location. At a particular temperature and relative humidity, if the temperature goes up, the relative humidity decreases.
Ok, in Death Valley you might be less likely to get fog than at my brother’s lake front in the evening, but that’s still a function of dew point. The air is so dry in Death Valley, that the dew point is extremely low.

If the temperature goes down, the relative humidity goes up. When you reach 100% relative humidity, you’re at the dew point and fog starts to happen. If you park your car in winter full of moist warm air, when the glass gets cold it will fog up. Especially when you turn on the heat without the defroster/AC - which dry out the air before it blows on the cold windshield.

When it comes to Florida, your reasoning is incorrect. We very often have fog here. When the humidity is not at 100 percent, sometimes not much higher than about 82 %. And as temperature tracks up-and-down, Humildty can go either direction get higher or get lower. Lived here for 12 years now and it is definitely the case here at least. Weather in the subtropics and trophics does not always behave quite the same as weather further North. If you're learning to go when I lost the house. It was 69° out and relative humidity was 82% and we had moderate fog for the first few hours.

It’s not “reasoning”. It’s literally the definition of Relative Humidity and Dew Point.

If these humidity readings are from your own inside hygrometer, it really has no relation to the RH% out doors.
If these humidity readings are from your own outside hygrometer, know that even fairly expensive meters are notoriously inaccurate, especially at the top end.
