Factual error: During the Nick Fury chase scene that takes place in D.C., several black and white state highway 6 signs are visible. These signs are unique to Ohio. Route 6 goes straight through downtown Cleveland where the scene was filmed. Plus during other chase scenes several Cleveland landmarks are visible in the background.

Continuity mistake: After the SHIELD agents have rescued the hostages, Steve begins a fight with one of the terrorists who tells him to take off his helmet. Steve takes it off and drops it beside him, leaving it on the floor. After Steve kicks the terrorist and runs over to him, you'll see in the next shot, that the helmet is still right beside him, despite his run.
Continuity mistake: On the bridge when the Winter Soldier attacks; when Steve, Natasha, and Sam are in the car stopped, a Hummer rear ends them and starts to push the car. The first shot of the Winter Soldier shows various cars near him. Then a brief shot of Sam, and back to the Winter Soldier and the various cars have changed drastically.
Character mistake: When Steve and Romanoff "switch on" Arnim Zola, Zola says "I may not be the man I was when the Captain took me prisoner in 1945." In the first Captain America, it was shown Steve took Zola into custody the same day as his friend Bucky supposedly died. However, the bio of Bucky shown at the Smithsonian earlier in the film said that he died in 1944.
Continuity mistake: After the Winter Soldier blows up the car he assumed Romanoff was hiding behind, she sneaks up behind him and kicks the gun out of his hand. When he throws her at one of the cars, the gun is on the road to the left of some yellow lines, next to a car. A few shots later, when the Winter Soldier picks up the gun, the gun and car have both moved - the gun is now right on the lines, the car is still the same distance from it.
Continuity mistake: When Steve and Romanoff are lying against the knocked over blinds after dodging the grenade, there is a box shown with some papers in it between them. The first shot shows a white piece of paper sticking furthest out of the box. Next shot, the furthest piece of paper sticking out of the box is now a peach coloured piece of paper.
Continuity mistake: At one point near the beginning of the infiltration of the helicarriers, Captain America's chinstrap has a twist from his right jaw down to where it covers his chin. This is visible in two shots. The next time his right side is shown afterward, the twist is gone. The chinstrap is too tight for it to have flipped on its own accidentally, and the pad which covers his chin is molded so it wouldn't have sat properly on his face even if it had somehow flipped around. There were undoubtedly several prop helmets made, and this one must have been put together incorrectly.
Continuity mistake: There is a sweat stain on Sam's jumper after he finishes jogging with Steve. As he lies against a tree, the stain is around the neck area and some of it is partway down his jumper. When Steve helps him up, the stain has reduced to just sweat around his neck.
Continuity mistake: After the bus flips, the truck that hit it stops right in front of a Corvette. But when the Winter Soldier is shooting at Romanoff, she takes cover behind a truck. In the wide shot, there is a Monaro, and SUV and a mini-van, but the Corvette is nowhere to be seen.
Factual error: When Rogers is launched through the front window of the bus after the Winter Soldier shoots him with a grenade, the bus is hit by a truck and flips. But if you look closely, the damage is minimal. On the truck it would qualify as a fender bender, and the dent in the bus looks like it was made with one decent swing from a sledgehammer. No way was that collision powerful enough to flip a fourteen ton bus on its side.
Continuity mistake: When the Winter Soldier approaches the car before throwing the grenades at it, one shot shows a water trail dripping at the front of the car he is hiding behind. A few seconds later, after Romanoff ambushes him, a wide angle is shown as he throws her at the car and the water trail is no longer there.
