Revealing mistake: Claire Bennett is accidentally tackled when she and Zach are arguing while watching the football game. Apparently, her neck is badly broken in the fall, even twisted a full 180°. However, if you watch closely as she falls, you can see that she is completely fine, stretching out her arms to take the impact before rolling around. She lands on her front, arms stretched out, all in all well prepared for the landing, and rolls around. In the next shot her neck is twisted in a way that simply wouldn't be possible in such a fall. She would have had to have her head stuck under something before rolling over, which she certainly did not. The guy tackling her did not land on top of her either. (00:19:40)
Revealing mistake: When Niki goes to find the 2 million in a case and open it, you can tell that all the money is fake as all the $100 bills have the same numbers. (00:37:37)
Revealing mistake: The money that Micah dumps out of his backpack is very obviously fake. In fact, the $20 bills have Benjamin Franklin's portrait on them.
Revealing mistake: When Mrs. Petrelli is sitting with the dead Peter, just before she lies down on his chest and starts to cry, you can see the "dead" man tilt his head slightly backwards. (00:21:10)
Chosen answer: Because he's an idiot. From the story point of view, they needed the vault to actually be physically open so that the release of the virus would be a credible threat. Unfortunately, this required that Peter conveniently forget that he could simply walk through The Wall and use his telekinesis to tear the door open instead. Peter's increasingly large arsenal of abilities, where he ended up having pretty much any ability required for any situation, led to a situation where it became necessary to either have Peter apparently forget that he had a given power, as with the vault door scene, or become naively trusting, as with his refusal to scan Adam's mind to confirm his good intent. This problem, which simply made Peter look increasingly dumb as the show progressed, may well have been a key factor in the decision to severely reduce his ability during season three.
