Revealing mistake: Watch the scene where Michael fights two guys for a purse. Michael calls KITT for help. When KITT jumps off a cliff, an old vehicle is the one that jumps off the cliff instead.
Revealing mistake: Just after Michael is about to be rammed by the two Land Rovers, he jumps onto K.I.T.T. and gets inside. The film must have been reversed as he is sitting on the right-hand side, but when it cuts he is then shown to be sitting on the left-hand side.
Knight of the Drones (1) - S3-E1
Other mistake: When Dr. Hallsten fires the rocket from behind the grill of the car, he uses the red plastic switch cover to launch it, not the actual switch.
Knight Rider [Pilot; a.k.a. Knight of the Phoenix] (1) - S1-E1
Continuity mistake: When the police helicopter sees dead Michael by the car, he turns 180ยบ around between shots.
Just My Bill - S1-E6
Other mistake: Just as Michael jumps over the roadblock, the whole front of K.I.T.T. flexes showing it's not a real Trans-Am but a mock up.
Knightmares - S2-E11
Revealing mistake: When Michael and KITT are going to jump at the dam in order to save Cara from drowning in the water container just before they jump you can see a stunt ramp below KITT.
Lost Knight - S3-E10
Plot hole: The explosion strength of the XPL nitro-plastiqe is very inconsistent. In the opening scenes, six cubes are enough bring down a building. Later, Bobby throws two cubes of it out the passenger window. Oddly, they end up on opposite sides of KITT, and then cause only very minor explosions. In the next scene, Bobby throws the another two cubes of explosive out the window, and those explosions are enough to collapse a power pylon. (00:08:26 - 00:08:49)
Other mistake: When Michael is carrying Micki up the cliff, she's supposed to be unconscious. But he's not holding on to her and her hand stays wrapped around his neck to hold on. Not something she should be able to do. When they're near the top, her hand position changes, but she's still able to hold onto him.
Mouth of the Snake [a.k.a. All That Glitters] (1) - S2-E21
Other mistake: At about 7 minutes into the show, you see a US border sign in English and Spanish lying on the ground. The English version says "500 yards ahead." The Spanish version says "150 metros" which is roughly 500 feet, not 500 yards. It is also not clear why a sign fairly far on the Mexican side would have English text at all, especially with wording that is more typical of US rather than Mexican signs. (00:06:49)
Revealing mistake: In most episodes you can tell different versions of the car are being driven. In most close up shots, or inside the car, KITT has a distinct black panel on the top part of the windshield and no rear view mirror. In some shots, the black panel has a different shape. But in most wide shots where we see real life driving, there is no black panel at all and sometimes there's a rear view mirror that can be seen. You can also see a normal steering wheel in driving scenes, especially during stunts.
Knight Rider [Pilot; a.k.a. Knight of the Phoenix] (2) - S1-E2
Revealing mistake: When the 2 crooks take KITT, when Michael's on the phone, KITT takes over and the driver keeps saying he's not doing anything and isn't touching the wheel. When KITT is doing donuts, you see the driver's hands on the wheel, and he's the one doing the driving.
No Big Thing - S1-E8
Other mistake: When the semi is approaching Michael head on, KITT tell Michael to hit the brake, which Michael does. Then KITT tells Michael to put it in reverse, which Michael does. But then KITT says "why reverse, we could have jumped over?" as if he wasn't the one who suggested reversing.
Good Day at White Rock - S1-E4
Revealing mistake: After we first see the pack of bikers riding, it cuts to two guys on bikes. They're being towed on a platform of some sort because the never turn their handlebars or front wheel but still turn with the curves in the road.
Continuity mistake: When Michael starts to scrape the blue paint off the shell, he scratches across the blue band and you see a few scrape marks where the paint is gone and it's white, like the shell, underneath. In the close up, it's slowly scraping such a small potion of the paint off and you see it's yellow underneath now.
Continuity mistake: When Michael notices the accident report folder, the folder is touching the red candy basket. When goes to steal it by putting it under the basket, the folder is now further away.
A Knight in Shining Armor - S2-E13
Visible crew/equipment: As Michael walks over to KITT and the loud mouth challenges him to a race, a light set up is reflected on the car.
A Knight in Shining Armor - S2-E13
Other mistake: After stopping Stone, Michael calls for KITT. When the car starts up, it's in gear, and the selector goes to P (park). After pinpointing the hidden entrance, the picture is of soft sand hills covering it. When KITT goes to enter, it's a defined entrance with a thin layer of stacked rocks in it.
Revealing mistake: In the warehouse, after Michael calls him, when KITT busts through the door, the plastic sheeting used inside the driver's window to hide the stunt driver is noticeable.
Other mistake: When the guy goes to go around KITT to get behind Michael, as KITT cranks up, you see movement in the front seat.
White Bird - S1-E19
Visible crew/equipment: After KITT cuts the plane in half, the camera looking on the left side of the plane is mounted to the wing's underside. A moment later, when KITT nears it, the camera is gone.
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.
