I think he should've told you right away what had happened to the latch since I'm sure he's aware of how safety-cautious you are by now.

Maybe sitting him down now and telling him that next time it happens to let you know immediately. I think there should be some communication about this and tell him (even if he already knows) how important it is to you to know that you are safe and everything is working correctly, such as the latch.

Sorry if I can't give any more advice.
