Here is a position that a chess engine will tell you white is winning, when in fact its a draw.
Capablanca has a great quote that applies today. Just replace the word "books" with "engines"
Chess books should be used as we use glasses: to assist the sight, although some players make use of them as if they thought they conferred sight
I actually would recommend not paying too much attention to engine analysis. The engine will tell you that something is a good move, but won't tell you why, and until you're much stronger (~2000), you will often be unable to figure it out for yourself.
An engine is good for spotting blunders and missed tactics. Otherwise, I wouldn't recommend using it too much.
