Audio problem: Jim has been beaten up in front of the Sierra and dragged back into his own car. When they drag him out inside of some warehouse, he says "Take it easy! I'm not struggling, am I?", but James Garner's lips are not moving and the line is obviously dubbed in. (00:24:30)
The Countess - S1-E4
Audio problem: The Countess' husband looks annoyed at the teenager frolicking in the pool. The sound does not match Sally's mouth. (00:10:30)
Audio problem: Driving his dad's pickup, Rockford gets flanked by one of the worst dressed killers in history. The guy shoots him about 3 times, but the audio is at really low level for a revolver shot from a couple of meters of distance and there's no flash or smoke indicating that any shot in fact is fired. Combined with the fact that it's preposterous that the guy could miss from such a short range and no arm/body movement is present, it's an adequate guess to imagine that the sounds have been added in post to add some sense of danger and were not planned when shooting the actual scene.

Tall Woman in Red Wagon - S1-E6
Audio problem: When Rockford is having his no dill lunch with Sandra Turkel, the audio, in particular at the beginning of the scene, changes ambience noticeably when the camera angle changes - not quite justified, they are sitting at the same cafe table. (00:05:20)
Audio problem: Warner Jameson is making perfectly clear to Jim how much in control he is. When he says that he plays a mean game, part of the audio is dubbed in and does not mix with the rest. (00:21:40)
