At the sing-off, when the Chipettes are singing, Ian uses his phone to make a video. At the end, he winks to his phone. However, when the video is seen on a website by some record executives, Ian does not wink.

At the end of the move, the chipmunks and the chipettes all say goodnight. All but Alvin, who then fusses with Dave with the lights. When Dave switches it off, Alvin switches it on, then Dave switches it back on. The camera switches back to Alvin and somehow the switch is "magically" switched back up.
While the chipmunks are spinning in the bowl on the food processor they start spinning counter clockwise, then the shot switches to a close up and when it switches back to the wide shot just before they are thrown out of the bowl, they are spinning clockwise as they are thrown out of the left side of the bowl towards the hanging pots and pans.
Jackie Seville referred to Toby Seville as her grandson, but he later referred to her as his aunt. This was actually not a mistake because Toby was talking to Dave Seville at the time, and he was describing her from Dave's point of view.
The chipmunks were spinning in the the bowl on the food processor and they flew out, the phone rang and they answered it. Somehow in between the time they flew out and they answered the phone, the food processor is turned off, but no one went back to it to turn it off.
When Ian is is controlling the toy helicopter with the chipmunks on it, he suddenly trips and the controller flies out of his hand. While in the air, it suddenly shrinks enough for one of the chipmunks to catch it. Once one of the chipmunks catches it, it is small enough to fit on Ian's fingertip.
When Ian takes the Chipettes to the roof they perform for him on the Jett Records sign. The sign at the very edge of the building facing the parking lot. As Ian sits on the roof and watches the girls, the sign can be clearly read, but as it is three dimensional made of stylized, cut-out chrome letters, it would be backwards when viewed from the street.
