I do remember being annoyed with the Fallout 3 A.I. for standing out in the open and not taking cover when I spray them with bullets. Idiots.
To be fair, that might be because taking cover behind some very common objects (cars) is considerably worse for your health than standing out in the open, mooning the enemy, and then trying to shoot them from between your legs.
In City of Heroes, allied NPCs can sometimes be more of a hindrance than help, as they try to attack everything in sight, and usually aren't that durable. Thankfully, you're rarely required to keep them alive.
A couple times in X-Com: Apocalypse my team acted like idiots. Normally the AI is great, and it works well for firefights. However, there's a suicide bomber alien rushing at a squad, so the squad takes cover instead of firing back. Alien gets in the middle of the squad, explodes, and then the ceiling falls and kills the squad (they're armored to hell, one bomb won't take em out. 10 tons of concrete, however...).

The AI try to hug the tank.
Every single time.
Especially if he is on fire.
And on Expert.
The only trouble of I've had with the AI on L4D is with the Witch. They won't sneak around her. I can take her out with no damage, but they often disturb her before I get the chance (I also have this problem with many players...)
