When Ponch is driving the getaway car in the first heist scene, it's shown as a Chevy SS right up until they arrive at the docks. As he's about to torch the getaway car, the car changes to a Chevy Malibu.
When Baker cuffs the guy driving the red Ferrari, Ponch takes the guy away from Baker in cuffs. Then with the camera view changes, the guy has no cuffs and his wallet in his hands and Ponch doesn't have Baker's cuffs in his hands.
At about 33 mins into the movie when Karen is in the pool talking to Jon, in one shot she wrings water out of her hair and lowers her hands, it cuts to a shot from behind her and when it cuts back, she's still wringing water from her hair. This happens maybe one more time.
When Ponch and Baker go to TJ's second home (0:51:38), TJ and Barton's drivers license are shown to them, you can notice clearly that David Barton's Drivers License shows an error in his Date of Birth (DOB), it says 41/21/1976. It was probably supposed to read 01/21/1976 or 11/21/1976.
Early in the film, Baker mentions that his right humerus (right upper arm) is titanium. At the end of the film, though, bullets are fired at him and they strike his left arm, causing one to ricochet and kill the villain.
