My interpretation is that it doesn't work reliably. As said, there
aren't any entries in logfiles.

Hibernating isn't worth taking a risk.

There's the dealers selling the hardware and warranty on the
hardware. Do you expect to behave a car as described above just
because you buy it as is? Do you buy cars certified by the
manufacturer to work reliably and to play nice with your specific
using conditions?

How do you deal with the plastic covers over the headlights many/most
cars have nowadays that go blind after a few years? It's obviously a
poor choice of materials made by the manufacturer, thus their fault,
and they should of course be replaced with no cost to you during the
lifetime of the car every time they are blind again ...

They aren't really telling you, that's the problem ...
