Other mistake: In the scene that Callaghan's daughter went into the portal, there is a track for the capsule to go into the first portal, but there was no track for the return portal.
Other mistake: Honey touches the pink ball and it explodes into a pink puff of smoke. Despite standing in the smoke with Honey, Hiro does not get any of the pink on him, whereas Honey is covered in it.
Other mistake: In the fight scene, right after "Gogo" takes over the car, she moves it into 5th gear, turning very quickly onto an extremely steep road. In this turn, she loses most of her speed because of a very large drift and then sharp turning. She never changed gears and went at the same speed up the hill, never taking any time to accelerate. This isn't the biggest mistake because this road was almost double the maximum incline for a road. In 5th gear, you couldn't make it anywhere near the top.
Other mistake: In the garage when completing his invention there are 12 blue bins full. But only 5 characters have a bin each entering the building, but there are 6 bins when they are chatting before the inverters show. (00:16:29)
Other mistake: To save the two from the portal, Baymax overrode his healthcare protocol by removing the chip and placing it in his glove. However, he still asked whether Hiro was satisfied with his care before shutting down.
Suggested correction: He says it before the moment when camera not looking at him for a second, when he had a chance to remove the chip.
