Continuity mistake: When Arnold shoots the crane tires, the motorbike is shown to have a windshield. Right after when the T-X knocks him off the bike the windshield is missing. The next shot is the ambulance hitting the bike and the windshield is back. (00:33:15)

Visible crew/equipment: During the "target acquired" chase scene when the red pickup truck flips over after going through the split semi-trailer there is an overhead shot shown of the action. The next shot when the T-X looks in her rear view mirror at the action, the camera crane that filmed the previous overhead shot is visible in the background. (00:32:25)

Revealing mistake: When they are driving the tundra after the big champion crane crashes, the Terminator gets in the truck. If you look closely, the truck's shifter is all the way in park. (00:37:55)

Continuity mistake: When John and the vet arrive at the mountain in their Cessna, the sun casts a shadow straight under the plane. The very moment they walk through the door into the hangar integrated in this mountain (which in the film is immediately after they landed), their shadows are in front of them indicating a low sun. (01:30:45)

Continuity mistake: When John is threatening to kill himself, his finger alternates from being on the trigger of the handgun to being on the trigger guard from shot to shot. (01:04:55)

Continuity mistake: When the TX pulls up to Jim's Burgers, notice the umbrellas in front of the store and the "in-out" arrows on the road. Asking for Jose Barrera at the drive-through speaker, she drives in and shoots him from the passenger side of the car and exits on the same side of the building she came in. You can see the front of the store with umbrellas upon entry and exit, yet the speaker has disappeared. (00:16:30)

Visible crew/equipment: Just before John Connor crashes into the car in front with the Tundra, there are a couple of shots shown from inside. During these shots, there is a cameraman visible on the extreme left hand side of the frame, hiding behind a black jaguar. (00:30:05)

Continuity mistake: When John talks to Catherine while sitting at the table in a moving RV, watch the explosives he is working on. Position of the charges changes with every shot facing Catherine. At one point they completely disappear from the table leaving only the Glock 18 handgun, and just a second later the table shown full of explosives again. (01:09:55)

Other mistake: When Kate is viewing the T-X on the security cameras, the two views of the corridor do not match each other. For example, the first camera shows glass walls, whereas the second shows wall panels. (00:23:30)

Continuity mistake: When the T-X steals the car in the beginning, she's weaving in and out of traffic and from her view we see that she is coming up to a truck in the right lane. The view changes to view from outside the car and she's turning into the right lane and driving straight ahead. The truck is gone. (00:07:50)

Continuity mistake: When the Terminator is hitting the T-X with the fire extinguisher, she puts her fist up and punctures it so the Terminator chucks it down on the floor. We see it on the floor again, but when the Terminator is running towards the T-X you see where the extinguisher was but now it has vanished. (01:18:55)

Revealing mistake: When the animal rescue truck crashes through the seminary gate, the sparks that fly come a few seconds after the truck hits. (00:48:25)

Continuity mistake: When the Terminator gets in the Toyota Tundra with John (after destroying the crane that the T-X was in), you can see that there is no seat belt in the seat belt holder. But when the Terminator is examining John for "brain trauma", there is now a seat belt in the seat belt holder. (00:38:00)
