Continuity mistake: When they get to the warehouse the door to the van closes, the shot changes it closes again.
Continuity mistake: When Jack and MacGyver jump out of the window, after they land the fire extinguisher by MacGyver keeps changing position from in his arm to on the ground.
Dia de Muertos + Sicarios + Family - S3-E5
Other mistake: A caption is misspelled towards the end - it says "cementario" when it should be "cementerio". (00:36:20)
Diamond + Quake + Carbon + Comms + Tower - S5-E10
Other mistake: MacGyver makes a diamond in his kitchen to mount on a ring to propose to Desi. He shows it to Bozer, and - miracle of miracles - it is already faceted. (00:01:30)
Rails + Pitons + Pulley + Pipe + Salt - S5-E9
Factual error: Every time the Phoenix Foundation airplane is shown, it has absolutely no markings. Every aircraft has to be registered somewhere and display its registration prominently, and no aircraft can fly in a country's airspace without a registration number at the very least. (00:01:55)
Factual error: They're in Malaysia where cars are right-hand drive, and they drive on the left side of the road. The traffic and in-car shots are all US/European.
Banh Bao + Sterno + Drill + Burner + Mason - S5-E4
Factual error: A tracker is found in the engine compartment of a government car. To disable it, it is stomped on. And sparks fly. Inert electronics do not emit sparks when crushed. It was powered by the car battery. (00:16:20)
Banh Bao + Sterno + Drill + Burner + Mason - S5-E4
Factual error: The whiz kid is attempting to remote control a car. He asks Mattie for her cell phone, and then opens it with his hands. That is impossible. It takes a lot of effort and tools to do so. (00:12:44)
Resort + Desi + Riley + Window Cleaner + Witness - S5-E1
Factual error: MacGyver and Russ are locked in a hotel room. They cannot use their comms. MacGyver says it is because the room is secure with reinforced walls to keep comms blocked. But there is a big glass window with only bars on it. If the room were indeed secure to comms there would be a screen to complete a Faraday Cage and prevent radio frequencies from passing through. (00:26:45)
Resort + Desi + Riley + Window Cleaner + Witness - S5-E1
Factual error: Riley and Desi pick the locks on a safe deposit box and extract a hard drive. They then are going down some stairs with Jane when Jane menaces them with a gun and asks for the hard drive. Riley tells Desi not to worry and shows her the actual disk in her hand. We're later shown she opened the casing with her bare hands and the disk dropped out - not at all possible. (00:29:30 - 00:32:00)
Resort + Desi + Riley + Window Cleaner + Witness - S5-E1
Plot hole: Paula Matos comes into her room and surprises Desi and Riley. Paula has a gun. Riley asks her if the gun is ceramic, as no guns are allowed in the hotel past security. It is not answered, but it would be the only way Paula could have a gun. So far so good. But later when they have made a deal, and they are leaving the room, Riley tells Paula to leave the gun behind because there might be metal detectors along the way. If it is indeed ceramic, then there is no need to leave it behind. And if it is metal, how did it get past the metal detectors in the first place? One or the other premise is wrong. (00:24:05 - 00:26:00)
Resort + Desi + Riley + Window Cleaner + Witness - S5-E1
Character mistake: "The Butcher of Brazil" walks into the "Spa" at the Zurich Grand. Instead of saying Boa Noite (proper Portuguese), he says "Buenas Noches" (in Spanish). (00:27:00)
Loyalty + Family + Rogue + Hellfire - S4-E12
Character mistake: Maddy is talking about "sending in the calvary." It should be "sending in the cavalry." (00:09:10)
Father + Son + Father + Matriarch - S4-E8
Factual error: Mac and Desi have been invited to a "pop-up" restaurant. There aren't many limitations on pop-up restaurants when it comes to choosing a location. You could host a pop-up in another restaurant's kitchen during off hours. Or you could set up shop on a city rooftop, at an apartment complex, or in an unconventional space. What is NOT a location is a place with swanky double entrance doors with the name of the pop-up restaurant in custom etched or frosted glass on them. Really? (00:06:10)
Lidar + Rogues + Duty - S3-E16
Other mistake: MacGyver arrives at an airplane crash site. It is smoking. Yet this is supposedly days after the crash. And there is no evidence of fire anywhere. (00:11:25)
Lidar + Rogues + Duty - S3-E16
Plot hole: Riley's father Ellwood shows up unannounced at Phoenix headquarters. The address for the Phoenix Foundation Headquarters is classified, as is Riley's job. How did he know where to go? (00:22:10)
Factual error: Scenes are in Puerto Rico, but the little girl looks Mexican and speaks with a Mexican accent. The guitarist was playing Cuban songs. And building codes in PR require concrete and concrete block structures for new construction, not wood, tar paper, and shingles. Wrong patrol cars, too. Real ones actually say "San Juan Police Department", not San Juan Policia. And they only use blue lights, never red. SWAT teams are part of the State Police, not SJPD, and legitimate trucks say "Special Weapons and Tactics" across the top and then POLICIA below.
Soccer + Desi + Merchant + Titan - S4-E5
Other mistake: A spectator has a vuvuzela in his hand. This is a horn that emits a very loud monotone. It is common at soccer matches where he is. But what is he doing with it? He is looking through it as if it were a telescope. (00:32:05)
