When agent Torres is placed inside K.A.R.R., a spiked implant stabs him in the center of his chest through his shirt. When Michael approaches Torres after K.A.R.R.'s destruction, there is no hole in Torres' shirt and no chest wound.
In the scene, that takes place in the shut down SSC. Billy realizes one of KITT's data packets has been downloaded to a young kid's XBOX360. The address on his computer screen read as follows: 707 Rocket Drive, Minneapolis, MN 55405. However Billy says the kid is located in Portland, Oregon.
Billy gives the name of the X-Box owner as "Cody Lundstrom". Billy's screen, however, shows the boy's name as "Cody Sandstrom".
The exhaust ports that provide K.I.T.T.'s turbo thrust are not engaged when K.I.T.T. turbo boosts through K.A.R.R.
How does a piece of data on a website accidentally get embedded into an X-Box game?
It was established that Charles Graiman built both the Knight Industries Two Thousand and Knight Industries Three Thousand in the premier movie and therefore could be assumed that he built both versions of KARR. Based on the disastrous events that happens in the 80s, it doesn't make sense that Charles would create another AI with the same flaw as the first KARR instead of creating a new AI with the programming of KITT.
When Michael, Zoe, and Billy are breaking into the SEC, they break in through what appears to be an ventilation unit. Since there is no security at the moment, why don't they just go through the hanger or the front door?
Why did Michael ask Sarah how she got into the SSC? Secret passageway aside, is it unheard of to assume that she got in the same way they did?
When agent Torres orders K.A.R.R. to stand down, it states that it only takes orders from Dr. Graiman. Since K.A.R.R. was reactivated using K.I.T.T.'s processor and data files, it would have already known that Dr. Graiman was dead.
