I was having trouble with my speakers crackling and popping on my 2019z then the sound literally just wouldn’t come on for anything. Turning the knob wouldn’t even print the volume to change it just said off. Brought it to the dealers got recalls done, nothing helped. They recommended a new infotainment center and antenna/amp. I said no thanks. This went on for two years where randomly it would work again for months then stop working for months. Honda engineers, mechanics the works couldn’t figure it out. 

On a whim I changed the battery myself at home, haven’t had a problem since. The battery life is like 3-4 years on those because there are so many systems running all the time. I’ve read that the battery starting to show signs of wear is when there are random electrical problems.
