I´ve renderd a car. After rendering there are litte black "boxes" at the front lights and the seats.

what could it be?

It's a bug that appears not often with a few objects, most of the time when they are transparent.
I'll try to fix it in a future version, even if I'm sure it can be easily corrected.
