Chuck Versus the Imported Hard Salami - S1-E9
Continuity mistake: In the scene where Sarah and Chuck find the suspected bomb, Sarah initially tries to disarm it by removing the numeric key pad under the display.

Chuck Versus the Sensei - S2-E9
Continuity mistake: The yellow pen that John Casey stabs into Ty Bennett changes between shots after Ty pulls it out. As he rotates it in front of the camera we can see that the bold BUY MORE logo is only printed once. Still in the very next shot, not only has the text changed direction (reading from the hat-side to the tip-side now), the logo have also appeared in front of Ty. (00:05:50)
Chuck Versus Santa Claus - S2-E11
Continuity mistake: When Sarah shot the Fulcrum agent and Chuck was looking that moment at his mom's bracelet, she has the bracelet on her left wrist and the red watch on her right. However, when she comes back to Buy More to talk to Chuck and hug him, she has the bracelet on her right wrist and the red watch on her left. Also, the first time Chuck showed her the bracelet, he put the bracelet on her right wrist.
Chuck Versus the Fear of Death - S4-E8
Continuity mistake: Near the end when Jeff and Lester confront "Greta" in the cage she pulls out her knife. Jeff attempts to disarm her but she cuts off his tie. She cuts it very close to the top, leaving very little around his neck, but when it cuts back to him after showing the piece hit the floor there is much more tie left.
Continuity mistake: During the car chase, the NSA's black SUV rams into Chuck's little car. The front license plate breaks off and is hanging on by one corner. When it's backing down the stairs, the plate has somehow reattached itself perfectly to the bumper. (00:29:20)
