This could be urban legend but it could be true. Most likely some rattles, squeaky noises and similar. BUT, some major issues could be discovered too, like Civic gen10 issue with mixing oil and gas.
I know new Accord had issue with HUD rattle. Fix was simple as implemented by owners themselves and I believe Honda has correct that in later production years.
Some people are brave or they need new car asap or want to be 'first on the block'. If you can wait, you could wait at least 3-4 months. I hope closer to the year end dealers will be more flexible with pricing AND potential issues might show up.
So far I only heard (on this forum) about bluetooth issue. My concern is more with transmission, engine, technology package and similar - major car components.
