Continuity mistake: When the Terminator drives the police van into the Cyberdyne building to rescue Sarah and John, one of the van's mirrors becomes crushed in on the side. Once the van is onto the freeway the mirror is intact again. (02:00:30)

Continuity mistake: The computer that the T-1000 reads in the police car (at the beginning) reads that John is 10 years old and was born in February of 1985. Which means that the movie would have to take place in 1995 (2 years before Judgment Day). Yet Arnold claims in the car, (while driving towards Mexico) that Judgment Day would happen in 3 years, just after the Skynet funding bill is passed by congress. (01:14:20)

Continuity mistake: In the shot where T-800 arrives in the time bubble, the bubble removes a clean cut chunk of the rear end of the truck. If you look at the very center of the wheel that is cut in half, there is part of the axle right at the tip of that wheel which is not cut. (00:06:25)
Continuity mistake: In the scene where the T-1000 disguised as John's foster mother, stabs Todd (foster father) through the mouth, she is standing at the table facing it. When it transforms back into its default form, it has moved away from the table completely. This is so that it can walk forwards (out of the shot) without having to walk around the table. (00:41:55)
Continuity mistake: When the T-800 arrives between the tractor-trailers, you can see a bumper sticker (i.e. "Vehicle makes wide turns") on the back of the trailer when the sparking begins. When Arnie arrives in the bubble it "melts" out the back corner of the trailer, and the sticker is no longer there. (00:05:50)
Continuity mistake: In the scene where the Terminator is nude in the biker bar, one biker stabs him. The Terminator then grabs the knife with his left hand and twists the biker's arm. Then the Terminator uses his right hand to hold the biker's arm down on the pool table while still holding on to the knife with his left. Immediately in the next shot, the Terminator right arm is in the air with the knife in his right hand and stabs the biker. (00:08:05)
Continuity mistake: In the hospital scene where Arnie is rescuing Sarah, he throws a black man against a glass wall. In the next shot the man is sliding down the wall and he's now white. (00:55:20)
Continuity mistake: When the Terminator pulls John off the dirt bike during the drainage ditch chase, the dirt bike falls onto its left side and the gas tank is about to be crushed by the tow truck.

Continuity mistake: When Sarah Connor hits the guy with the broom handle in a bid to escape, after the first hit, we see a close-up shot of him on the ground clutching his face. In the background we see her swing back and start bringing it down again. We then cut to a wider shot, and she repeats the motion. (00:52:40)
Continuity mistake: When the T-800 and Connors are leaving the hospital in the car driving backwards, the car jumps off a grassy embankment and lands hard on the asphalt, knocking the rear bumper loose to a hanging position. A few shots later the bumper is back on snug again. (01:04:50)
Continuity mistake: At the Galleria, the T-1000 fires rounds into the Terminator's back, but the damage to his jacket disappears when he is thrown through the window. (Director James Cameron said the scripting of this sequence at the time of filming was different). (00:32:10 - 00:32:55)
Continuity mistake: In the desert when John says "bad example", he turns round and his hair has changed. It goes from in his eyes to neat and by the side of his face. (01:12:30)
Continuity mistake: The gas that the Terminator shoots at the SWAT members while inside the foyer of the Cyberdyne building, is nowhere near the front door when compared to when the Terminator exits the building. The Terminator has to walk through a gas haze as he opens the front door. (01:59:45)
