Continuity mistake: When Christine is fixing herself after the guys smashed her up, her front end is shown to be perfectly straight for its entire width and the hood is missing. Near the end of the scene, the front end is shown crushed and unfolds again, and the hood appears from nowhere.
Continuity mistake: At the the end of the film, Dennis uses the Caterpillar tractor to ram Christine. He also immobilizes the car by dropping the teeth of the loading bucket into the roof. Then we see close-ups of the car repairing itself completely. The next shot, just before the tractor starts to crush the car, shows the car in its previous smashed-up condition again. (01:44:15)
Continuity mistake: When Buddy stops his Camaro in front of the fuel station's service bay, the car is oriented at about a 45% angle to the facade of the building. But as he and the others step out, the car is parallel to the facade. This is even more obvious just as Christine crashes into the Camaro for the first time. (01:15:05)
Continuity mistake: When Christine is crushed and dropped from the junkyard crane, the side facing Dennis, Leigh and Junkins shows a steel wheel very prominently. As they talk, they are looking right at it, and when the shot returns to the cube, the wheel is gone, replaced by Christine's mangled grillwork and front bumper- as if the cube has spun 180 degrees. The viewing angle is unchanged, evidenced by the crane's tread belts and the area in the background, and if the cube were 'morphing', the 3 characters would have seen it and reacted. (01:45:10)
Continuity mistake: At the gas station that explodes, a car is lifted high in the left service bay, but is down on the floor when the building explodes. To try and fix this continuity error, a quick close-up shows the controls for the right bay's lift as Christine shoves the Camaro inside the right bay, smashing those controls. This should have no effect on the left lift (each lift is completely independent for safety), yet two quick close-ups (of the blonde guy, then his feet) show the car on the left is now coming down. But long before it could have traveled all the way down, the next shot is from outside as the building explodes with the car firmly on the floor. (01:15:55)
Continuity mistake: When the gas station explodes, one closer shot shows the far right end of the station where the tow truck is parked next to two fuel pumps. Behind the truck, the grounds erupts with a huge explosion. The next shot shows the entire station from further away, and at the right is the truck and two pumps with no fireball rising behind them, yet there should be. (01:16:50)
Continuity mistake: When Christine is about to push the Camaro sideways into the service bay, an interior shot looking at Trelawney in the bay, screaming, shows that the Camaro is already moving sideways before it is hit by Christine, yet the next exterior shows it isn't moving yet. (01:15:55)
Continuity mistake: When Leigh is choking inside the car at the drive-in, the speaker hanging on the driver-side door glass changes location. When the interior is dark, it is forward, against the vertical chrome bar. As the interior gets brighter, the shot from the back seat looking forward shows the speaker is completely missing. When the interior gets really bright, inside shots show the speaker is a few inches rearward from the original location while exterior shots show its move even further forward. And when dark again, the speaker is where it was at the start. (00:47:40)
Continuity mistake: Christine's instrument lighting is green in long shots and white in close shots.
