The auto high beams work fine on my Civic. They're not too quick to switch back on after someone passes me, but they work.
The thing is, when I manually intervene (switch off the high beams or flash someone) I have to "reset" the auto lights. Just flick the switch to another position and then to AUTO again.
Traffic sign recognition works very precisely- indicates the change in speed limit the moment I pass the sign.
Seems like you could have an issue with your camera module since both systems rely on it to function correctly.
I recognize the signs with my eyes
