If it makes you feel better, electronic componentry exhibits a bathtub curve failure distribution. In other words, failure rates of components are highest very early in the lifespan due to inherent defects or manufacturing errors and then then failure rates drop precipitously until some later point when wear (mostly heat) eventually degrade them, then failure incidence rises sharply. For high density microchips of which there are many in the modern vehicles even the best fabs will have duds. Advanced lithography is not fool proof and the physics and margin for error are challenging enough that some defects are given. Hence chipmakers 'bin' high performance chips because some come out perfect, but most do not. Imperfections do not generally inhibit functionality until they do which generally manifests in use as the initial curve spike.

In a sense, getting these bugs out of the way very early when the dealer and manufacturer are most motivated to resolve them is ideal. Kind of a shake down run, put it through the paces, see if anything has issues, fix them and then hopefully you're golden for the next 300k miles.

For this reason, I like to go through systems test a few times early in a vehicles lifespan. Check feature function a few times, engage lockers, transfer case, sway bar etc to make sure everything operates smoothly and functions properly. The worst time to test your transfer case for the first time is when you need it.
