anyone else getting this? A dashboard popup 5 minutes after starting the car. Says "Temporarily Unavailable Camera View Restricted" and shows symbols for active distance assist, lane change assist, braking assist, etc. Took it to the dealer and service advisor says "oh yeah we've seen lots of those."

I would check to see if your tire pressure is being reported as slightly low.

I've seen two kind of camera issues. One is from moisture in the area between the camera and the windscreen, this usually comes at winter or in a cold and humid weather and it appears pretty soon, perhaps within a minute after start and then goes away after several minutes ones the camera heating makes moisture disappear from the camera view. This is normal and comes on all cars at certain conditions.

The other one I've seen happened most often only after some 20 minute to an hour drive (light traffic may affect the time). This concerns the stereo camera and throws an unavailable message for several assist features. Active distance assist and braking assist were the most common ones and more could come during a longer trip. This happened on the wife's car that has the same stereo camera as a MY22 W223. The car visited service several times but finally the workshop changed some "deflector" part and the issue stopped occurring. Not sure which exact part they changed, Parts Information does not seem to have any individual part around the stereo camera that could be related. A warranty fix and they did not give the customer any details about the part.

I on occasion get a flurry of nanny features going offline. After I reach my destination and switch off the car, these features always come back online. Just yesterday, my Active Ambient Lighting went haywire and threw an error message that it was unavailable. When I got back in the car after a Costco run, everything worked fine. I think @Diesel Benz hit the nail on the head when he said the front-facing cameras lost their minds and threw the errors. My ambient lighting issue yesterday was a first for me; not sure what got it riled up.

old thread but thought I’d chime in.

Been dealing with this error for over a year. Initially told clean lenses and windshield. Didn’t help. Dropped car at MB dealer yesterday for recall replacement of gas pump (2022 GLE 450) anyway showed them pictures of persistent warning“Temporarily Unavailable Camera View Restricted”

without a beat was told by my account specialist of 12 years … yup I know what that is you need a new hood.
covered as tech/software/hardware error.
