(at around 1h 1 min) During the car chase the rear right hand tire of the black SUV is clearly shredded and running on the rim, but in the next shot the tire is full again.
(at around 1h 4 mins) During the fight in the sporting goods store, the blue-shirted employee behind John disappears and reappears between shots.
(at around 1h 3 mins) Just after the turn, John slams into Magnus's vehicle and causes his own rear passenger window to shatter. Just as the tire is blown and they go onto the next few shots, it's clear that the same window has now repaired itself, even after the car rolls and crashes.
(at around 1h 3 mins) Magnus aims the shotgun right at Sarah, through the window, and fires, but the front tire gets shot out instead.
(at around 1h 3 mins) As the car flips, you can see the front bumper has somehow repaired itself completely.
(at around 11 mins) After Magnus vomits, as he exits the house we can see his vehicle is running already - there is vapor emitting from the exhaust pipe. Yet when he gets in the car he has to turn the ignition key.
When John smashes Magnus's head in with the ball bat, it is obvious that he is just smashing a wooden prop (unrated version).
(at around 1h 3 mins) Just as John's car flips you can clearly see bursting to the left the blow canister which aids the flip.
When the driver exits the black Ford Explorer after it rolls, the rollcage is clearly visible when he opens the door.
No mention is made to any of the Unisols needing to be cooled off every so often due to their body temperatures despite this being prominent in previous installments.
