Factual error: In the bathroom scene at the motel where Lucy is in the shower and Mimi is using the toilet, Mimi flushes the toilet and Lucy yells "Ahh, freakin' cold," however, if someone flushes a toilet whilst another person is in the shower then this would result in the cold water being removed from the shower, so Lucy really should have yelled "freakin' hot," unless the toilet water was hot water.

Factual error: When Carl first receives 26 at the hatchery, he asks what kind of dinosaur she is. He is told she is a Hadrosaur (duck-billed dinosaur), but when we see her, she is some sort of Ceratopsian (i.e.: Triceratops). She is later referred to as a Chasmosaur (which while not looking like 26, IS a Ceratopsian).
Factual error: Just after Austin recollects what Mini Me did last time he used the peace symbol, they both smash bottles to use for fighting. Austin grabs his out of a gift basket and Mini Me grabs his out of the mini fridge. Considering the location of both Austin and Mini Me's bottles, shouldn't liquid come out of the bottles because they are new? (01:03:40)
Factual error: In the introduction, when text flows across the screen, the words "ten thousand solar systems" appear. Strictly speaking, there is only one Solar system - ours. A star with planets is a "star system", our star is called "Sol", hence, the Solar System. This trivial error is made in many sci-fi films, BUT the Star Wars series has never fallen into this error before. Remember Episode IV, where Leia says something like, "The more you tighten your grip, the more star systems will slip through your fingers" (and that's only one example). So why has George Lucas allowed such a trivial but irksome error to be made here? [Some people have debated this point, saying that "Solar" from the Latin "Sol", can mean any star system, but it's backed up in the Isaac Asimov book "Nemesis". He knows a thing or two about sci-fi, and in the book a new star is discovered and called Nemesis, and its system is referred to as the "Nemetic system", as opposed to our own "Solar system".] (00:00:55)
