Engines are bad at evaluating any position whose moves must have an impact greater than 10-15 moves later. Within this window they are very accurate, but outside of it they are completely blind.
Endgames provide countless examples of computer misevaluations. But also closed positions and openings. Their moves are not bad, but you can't trust the number evaluation without doing some work with the engine.

but, this is a draw game by perfect play. interestingly, the perfect play is very easy for black - he has to move his king b8 and c7 repeatedly.
