Revealing mistake: When Dom is on the bridge and swerving with the safe, tyre marks from previous takes can be seen on the ground. (01:46:50)
Continuity mistake: When the Chief of police asks Hobbs if all this is necessary, Hobbs is looking at the officer. Camera cuts and he is looking at the file. (00:20:20)
Continuity mistake: Throughout the vault scene, the amount of police cars in pursuit is constantly changing. In one shot you have 4 black and white cars and 2 yellow 4x4's. Next shot the 4x4's have gone. (01:45:00)
Continuity mistake: When Paul and Mia jump off the roof in the favellas, in one shot Mia is in a sitting position in the air with her legs out in front of her. Camera cuts and she's now in a walking position, as if she would land on her feet. (00:33:45)
Continuity mistake: When the buggy first pulls alongside the train, in the first shot, the train is past the buggy. Camera cuts, and the train is next to the buggy. There is also shot where the buggy is in the sun, but after a cut the train's shadow is over the buggy. (00:09:55)
Factual error: Given the specs given in the movie (7x12 feet) and assuming standard container height (2.389m) and 45cm thick walls, the vault would weigh at least 73.76 tonnes. Not 10 tonnes.
Other mistake: Throughout the vault scene, Brian and Dom have black cars. Several times they bump into each other without getting any damage. (01:47:10)
Revealing mistake: When Dom and Brian skid to hook up the safe at the police station, tyre marks are visible on the ground from previous takes. (01:41:50)
Continuity mistake: When Hobbs is knocked off his feet by the RPG blast, the amount of dust on his shirt keeps changing. (01:36:15)
Plot hole: Reyes is the only one able to open his vault in the police station as shown in the movie. All the cash from the cash houses are taken to the vault and we see Reyes arrive to check the money is in the vault. How did the money get in the vault if only Reyes himself can open it? To assume the vault is kept open would be ludicrous as it would defy the whole point of the vault. (00:52:30)
Suggested correction: Reyes has all of his money taken from the safe houses to the police station, all at the same time. Yes, the vault is kept open until all the money gets there and then it is closed. There is no other way to do what Reyes wants without leaving the vault open. Bear in mind that under normal circumstances the money itself has very little actual security, because nobody else would be crazy enough to attack one of Reyes' safe houses.
While your correction is good in respect of the money being taken to the vault, my mistake was referring to the point before the heists. Reyes orders the money to be taken to the vault after the one safe house is hit. And when all the cash is being brought it, yes the vault would be kept open. But what about before the first hit on the safe house? It is extremely unlikely that the vault would have been open prior to this. So how was the vault opened to allow all the money to be brought in in the first place? If only Reyes can open it.
We don't know anything at all about the safe or its contents prior to the money being consolidated. It very well could have been completely empty and unlocked. Reyes could have unlocked the safe, left the building, and only returned once all his money was there. There just isn't enough information for this to be a plot hole. Remember, Reyes is only doing all of this because Dom burned his money. He fully trusts the cops to keep his money safe and it is fairly well established that nobody else in Rio would even attempt to steal from him.
