Revealing mistake: On the ice the tank is firing - in slow motion we see empty shells are littering the area. The shells have crimped ends, revealing them to be blanks.
Other mistake: When Dom and Cipher break into Mr Nobody's base, they use "the latest in concussion grenade technology which scrambles all senses and lasts an hour" which would include vision and is reflected as such. 2 min later Letty and Hobbs are able to see the kiss Cipher gives Dom.
Plot hole: Cipher took control of a lot of cars to stop the Russian and take the briefcase. Then Dom's team showed up and he had to escape with no aid from her whatsoever. Did she forget she could control cars?
Suggested correction: The cars they were in might not have had anything that allowed her to control.
Continuity mistake: During the car chase in New York none of the grappling hooks appear on the cars until they are needed, most noticeable on Roman's Bentley.
Continuity mistake: When the red Toyota starts up and rams the taxi in the New York scene the front off-side light cover pops off. In the next shot when it pulls away the light is repaired and the damage on the front is less, like brand new.
Continuity mistake: When Owen Shaw is shown to the team on the screen, in the first shot his last name is spelled "Shao" and in a following shot it's corrected to say "Shaw."
Plot hole: Anything conducting electricity within the blast radius of the EMP, and not in a Faraday cage, would have been permanently fried. Since the whole base was within the radius (needed to take out the gate) including Dom's car and the Submarine, Cypher's plan was flawed from the beginning.
Continuity mistake: At the end of the movie in the ice chase scene, Hobbs' get away truck has tank tracks for wheels, not tires. When he rams the Russians coming from the right, you can see his getaway truck has a tire on the front left. The next time you see the truck it is back to having only tracks again.
Other mistake: When the team get off the sub they leave the hatch open. That can only be closed manually, so the sub would have simply sunk within a few minutes of submerging.
Plot hole: Dom arrives in New York at the same time as Hobbs and his team. Dom meets up with Shaw's mum and then proceeds to steal the nuclear codes. Meanwhile at the same time, Hobbs and the team arrive at their secret hideout and start preparing the cars. The time frame isn't the same - Hobbs and co. simply haven't got the time.
Suggested correction: There are time lapses between when they arrive and the heist takes place.
Dom crosses the bridge as Hobbs and Co go underneath then Dom stops to change the spark plug a cover to have his pre arranged meeting with Shaw's mum, he then proceeds to do the heist, there is no time lapse.
