Just before the NATO base scene Luke is talking on the phone with the crew and is clean shaven. In the next scene his French beard is back again.
When Hobbs is in the Humvee with his partner during the Shaw chase he has no facial hair. In the next scene when meeting up with Dom's team the facial hair has reappeared in full.
In the tank chase, the exact same Toyota Corolla is seen in three different scenes (plate "NE34 12").
At the end scene at the original house in L.A. when Hobbs and Roman exchange insults, Tej's drink disappears and reappears between shots.
During the street race in London, Letty's Interceptor is equipped with an automatic transmission with a racing shifter, however during the race Letty is seen pushing a clutch pedal numerous times. An automatic car does not have a clutch. In one scene, as the car is accelerating she can be seen shifting the car from "2" to "1" on the automatic shifter.
The longest paved runway in Spain (where the scene takes place) is at Madrid's Torrejon airport, at ~4,800 meters, or about three miles. The heroes chase the villains down the runway (apparently unaware of where they are) for about a minute before the plane appears, thus eating up at least one third of the runway's length. The plane, an Antonov AN-124, plans to do a touch-and-go - a landing and immediate take off, once the villains are aboard. While this is certainly possible in the last two miles of runway, such a maneuver should take approximately one minute. Any longer at over 100 MPH, and there wouldn't be any more runway to fly over. The length of the scene is far beyond anything even remotely possible under the circumstances.
When Brian O'Conner is being escorted from a plane by U.S. Marshals, the Marshals are wearing jackets with the misspelling "Marshall" printed on them.
Just before the police raid Owen Shaw's hideout, near the beginning of the film, Owen is repairing his custom built car and remarks about switching out a bad part. The part in question is a spark-plug. It is later mentioned that the custom car is actually a diesel turbo car; which don't use spark plugs.
Spain does have an extradition treaty with the US. The Canary Islands are Spanish.
The headquarters of INTERPOL are in Lyon, France not in Moscow as appears.
No matter where they are in London the cars always pass the same number 4 double-decker bus.
When the plane lifts up the Jeep on the runway the tail shaft under the car is missing.
In the first chase scene when Dom's crew is chasing Shaw's crew in the low-rider cars, Shaw's men fire 3 electric devices into their cars to make them malfunction. The third one landed on the front bumper of O'Conner's car. However later is it shown on the driver's side and he is able to take it off by side swiping a pole.
Despite the absolute beating Roman, Han and Hicks suffer during their respective fights in the subway, none of them show any bruising or effects afterwards. Their skins are all unblemished.
When Hobbs and Shaw face off in the car park at night, and Dom targets Shaw with a laser sight from a building at height (as he is aiming down), Shaw moves and the laser point crosses his jacket zip revealing it is coming from in front and below (most likely a fixed position a few feet behind Hobbs right side) as half the dot on Shaw's shirt is above the half on the zip in front of the shirt.
Shaw's movement also reveals the laser is fixed as it does not track him as he moves (as a real sniper would do) and further reveals the low position of the pointer as he moves back and the point travels up over his shoulder.
There are several car chase scenes in London, however all the London police car sirens in the movie are actually American police car sirens, the London siren is a more drawn out sound.
Sound track for the Alfa Romeo Giulietta was dubbed from the previous movie. Sounds come from Brian's Subaru impreza
When Hobbs shoots the vending machine in London, the chocolates in the machine are chocolates found only in vending machines in the USA and not the UK.
The bridge after the opening credits they say is in Moscow, is actually Lambeth bridge in London, a few buildings have been edited in and some are missing, but it is Lambeth bridge.
When Tej uses the ATM (Cajero Automático), the signage displays "Banco Principal de Costa Rica." There is no such bank in Costa Rica. Also, the scenes were not shot in Costa Rica, as there is no location in Costa Rica which even comes close, in visual appearance, to the site used in this scene.
In addition, the bills dispensed by the ATM are red. No ATM in Costa Rica would dispense Red bills, as those are the equivalent of less than $2 in Costa Rica -- the Red Costa Rican bills are also smaller than the bills shown in this scene, and are made of plastic, not cotton/paper. Costa Rican ATMs dispense Green and Dull Orange bills... and, occasionally, Yellow bills.

Throughout the film, Shaw is portrayed as a rational but ruthless arms dealer who kills when necessary (a failed employee, someone whose death will advance his scheme, collateral damage), but not wantonly. During the tank chase, his persona morphs, inexplicably, into a psychopathic mass murderer, intent on causing as many deaths to innocent bystanders as he can, and he appears to be enjoying it.
After Letty and Dom's street race he talks about the first time they met, during his first street race at the age of fifteen. Though, in the first movie (The Fast and The Furious) Mia tells Brian that Letty and Dom have known each other their whole life as they've lived in the same neighborhood but Dom only showed interest in her at the age of sixteen.
During the plane chase the team shoots 4 grappling arrows into the wings of the plane to attempt to keep it from taking off. 1 of those arrows through the engine would have taken out that engine, which would likely have prevented the plane from taking off. 2 and it certainly would have been prevented. Of course that would have removed the drama of the cars being lifted up and down off the ground by the plane as it struggles to fly.
When Dom and Shaw talk face to face in the night after the street race between Dom and Letty, Dom offers Shaw a deal: "I walk away when she (Letty) walks away", implying that he and his crew would stop hunting Shaw if Letty quit his team. Yet in the first London meeting between Hobbs and all of Dom's crew, it was clearly stated by Hobbs that the objectives for them were to hunt Shaw and bust his mission and not only bring back Letty to Dom's side. Besides, in the same meeting, Brian and Dom had bargained with Hobbs so that if they hunted and busted Shaw, Hobbs would manage to grant them pardon for their crimes. Did Dom forget about about the agreement he made with Hobbs when he offered a deal to Shaw? Or was he keeping his promise and lying deliberately to Shaw ?
When the character Tej Parker first appeared in 2 Fast 2 Furious, he is shown with tattoos on both his left and right arms (as his actor does in real life). When he is reintroduced in this movie, he is shown with no visible tattoos on either arm.
After Denlinger shoots the chip onto the cars, Klaus says, "Chip 1 is ready," in Danish, yet none of the other characters is Danish.
