Plot hole: It makes absolutely no sense why the Terminator, who is a programmed killer, chooses not to kill anyone in this film. In Terminator 2, he didn't kill because John, who was his master, ordered him not to. In this film, we learn that John is not his master. Kate Brewster is. And she spends most of her time complaining and trying to escape from John and the Terminator. She certainly wasn't gonna bother giving the Terminator a pep talk on no killing. So it just remains a plot hole.
Suggested correction: Kate Brewster told the Terminator not to kill when she reprogrammed him in the future. It's a logical order to give since its mission is to protect. It's likely John gave her that idea in the future when telling her about the terminator from T-2 (before he died of course) who he gave the same order to.
I agree, but it is also possible that Kate programmed him not to kill anyone.
That's what I said.
Other mistake: After the T-X is hit by a truck, her primary weapon is damaged and she is seeking a replacement. As she is cycling through available weapons, dummy text is below the weapon name. The text reads: "TEXT regarding the current weapon is being displayed in XP040 weapon sub-window. Important information regarding this weapon is being displayed here." (00:59:52)
Revealing mistake: When the Terminator, Kate, and John are escaping the cemetery, they come down a winding road and drive in front of the camera in a hearse. Both Kate and the Terminator have been replaced by stunt drivers.
Audio problem: When Arnold makes the slow turn at the cemetery from Dr. Silberman's view, he starts firing his weapon at the police but we don't hear it. In the very next shot, he repeats the same action but we hear it this time.
Audio problem: When the T-X steals the car in the beginning, she's driving with both hands on the steering wheel. The car appears to be a 2001-2003 Lexus SC which has a 5-speed automatic transmission (without steering-mounted paddle shifters). However, the sound from the transmission indicates it's a manual transmission rather than an automatic transmission. Therefore, she cannot be shifting gears while having both hands on the steering wheel. (00:07:15)
