Continuity mistake: Even after KITT's voice modulator changes to the three bars in the episode "Hearts of Stone," any shot of KITT starting himself up still shows the old voice modulator (a simple red square).
Knight Rider [Pilot; a.k.a. Knight of the Phoenix] (1) - S1-E1
Continuity mistake: If you look closely at KITT throughout the pilot, the position of his scanner lens changes from being the normal scanner that we're all used to, and the scanner being at the very tip of the front bumper. (The latter case is because the car was used for a promo shots to sell to NBC, and after the show was picked up, they changed KITT's look, but still used the earlier shots).
Knight Rider [Pilot; a.k.a. Knight of the Phoenix] (2) - S1-E2
Continuity mistake: During Comtron's Demolition Derby, Michael engages auto control. Michael controls the wheel during the ski mode stunt. When the car drops back on four wheels, Michael is driving with a regular steering wheel instead of KITT's steering wheel.
No Big Thing - S1-E8
Continuity mistake: At the end when Michael is driving Devon in K.I.T.T, there is a truck behind Devon which isn't behind Michael, depending on who is talking in the shot.
Continuity mistake: When Michael and K.I.T.T. go to rescue LT. Ladd off the firing range,the steering wheel isn't K.I.T.T.s usual steering wheel, it has metal bars coming out to the handgrips.
Continuity mistake: In the first few episodes watch KITT's glowing square. In some scenes the flasher says KNIGHT 2000 and other times it does not.
Blind Spot - S2-E5
Continuity mistake: After the KITT and Porsche chase scene, the police officer on the motorcycle comes to a stop in the dead-center of an intersection. But in the next shot when he looks around, he is barely inching into the intersection.
Continuity mistake: When Michael finds the stolen moving equipment, he parks KITT and then starts to climb down an embankment. The close-up shot of KITT's scanner reveals a tree in the hood's reflection. But when we saw KITT stop, there wasn't a single tree around.
Knight Rider [Pilot; a.k.a. Knight of the Phoenix] (2) - S1-E2
Continuity mistake: As Michael realises how he will be stopped on the way to the airport, he pulls over. KITT's front lower bumper does not have its spotlights, it is just a plain bumper.
Continuity mistake: At the beginning of many shows it will show the car's instruments, panning from one to the other. The speedometer will show various speeds in that shot, but a close up of the gauge will then show 55 MPH.
Knight Rider [Pilot; a.k.a. Knight of the Phoenix] (2) - S1-E2
Continuity mistake: After Michael gets shot and gets in his car to race to the airport, he calls Devon on the intercom. Before he gets into the car, he flinches and grasps his left side shoulder area where he was originally shot. When he talks to Devon, he's grasping his right shoulder. After he finishes talking and continuing the drive, he grasps the left one again.
No Big Thing - S1-E8
Continuity mistake: As KITT and the truck approach each other, the terrain alternates from tree lined to wide open. Also in the same sequence, after KITT suggests reverse, Michael's hand is shifting from reverse to the low gears.
Give Me Liberty... or Give Me Death - S1-E15
Continuity mistake: The General Lee explodes in flames, but in the next shot of the car, you can see that the car on fire is a completely different car. (00:28:50)
Lost Knight - S3-E10
Continuity mistake: The red wagon has Bob's plumbing painted on the side of the driver's side door.When being chased by Michael Knight, the sign is missing. It reappears later when Doug is playing inside it.
Continuity mistake: When Michael picks up the locket and opens it, the way he holds it with his fingers changes in the close-up shot.
Continuity mistake: When Gina locks the door after Michael leaves, the close up of the lock is different than the one on the door. On the door, the top of the faceplate is right next to the deadbolt knob, but in the close-up there's a lot more space that you can't even see the top of the faceplate.
Continuity mistake: When Michael is getting Dr. Bergstrom out of Goliath, he steps onto K.I.T.T.'s hood and Bergstrom is to his right, in the next shot Bergstrom is to his left.
Knight Rider [Pilot; a.k.a. Knight of the Phoenix] (1) - S1-E1
Continuity mistake: When KITT first stops talking the Auto Normal and Pursuit mode indicators change from old fashioned very angular with a different font and switches to the newer rounded rectangle with then new font. It does this several times.
Continuity mistake: Toward the end of the episode, the convoy moves out, with KITT bringing up the rear. If you look, there's nobody in KITT's driver sear. As KITT exits the yard, Michael is suddenly there, driving as usual.
Continuity mistake: Watch the scene where KARR engages in bank robberies. In one charge scene, KARR has the sticker job from Slammin' Sammy's episode, which it doesn't have at any other point.
Answer: I would say that unless there's visual evidence it was another K.I.T.T. car, as in you could see the bar scanner or cut steering wheel, people on here would correct the mistake by saying more than one 1982 Pontiac Firebird Trans-Am was sold and there's no reason it's meant to be a random car.
