(at around 7 mins) During the playback of the beginning of the airport battle that takes place during Captain America: Civil War (2016), Spider-man's line after stealing Captain America's shield is "Hey Everyone". In Civil War, he doesn't say anything until after Tony speaks, and they exchange several lines of dialogue before Peter delivers the "Hey Everyone" line.
(at around 4 mins) The opening of the film states that the Battle of New York was eight years prior. This is a mistake. Tony Stark states in Avengers: Infinity War (2018) that the events of The Avengers (2012) happened six years prior. Also, Vision states that for two years he and Scarlet Witch have been trying to make a relationship work, putting Captain America: Civil War (2016) (as well as this) two years prior to Infinity War, four years after The Avengers. This cannot take place eight years after The Avengers if Infinity War takes place 6 years after. Even the directors of Infinity War have stated that the "8 years later" was a mistake.
(at around 13 mins) The Academic Decathlon poster is seen twice, but with different dates. Once just before the lunchroom scene, and it shows the date of the competition to be October 13-15th. Later (at around 46 mins), when Peter is with Ned, and he decides to attend the Academic Decathlon to chase the villains, they both look at a poster of the event hanging on Peter's wall, and the date is for one day, September 14th.
(at around 7 mins) Peter's video at the beginning of the movie differs from what is shown during Captain America: Civil War (2016) when Ant-Man becomes Giant-Man. In Peter's video, you see Ant-Man grow in the background and Peter says he's big now and has to go. In Civil War, they show Spider-Man's immediate reaction is to shout "Holy $&#!".
(at around 1h 35 mins) In the car chase, when Peter is in Flash's Dad's car, he supposedly doesn't know how to turn on the lights and makes Ned on the phone find out for him. However, the rear lights are on in the insert shots showing the car from the rear and there is no way to turn on just the rear lights without the headlights.
(at around 39 mins) It is established multiple times in dialogue that Liz's house party is held on a Friday night, yet Peter and Ned have school the next day.
(at around 1h 19 mins) When Iron Man welds the lower deck of the Staten Island Ferry back together, that would have done nothing to prevent the vessel from sinking. In fact all that it would have done is allowed the water already in the below decks hold to have remained where it was.
For loaded vessels to float, a sizable portion of them have to be below the water line to displace the amount necessary for them to float. That area cannot be filled with water because that would cause the vessel to sink due to its weight. Iron Man would have needed to dive under the ship's hull and also welded the split along the keel to prevent it from sinking.

(at around 1h 3 mins) The top of the Washington Monument is missing the lightning rod.
(at around 19 mins) When Peter stops the bank robbers, they are all wearing Avengers masks. The Thor mask has the signature helmet from the comics, which movie Thor (2011) never once wore on Earth. In the movie universe, where did this design come from?
(at around 1h 16 mins) The ferry was still moving forward when the accidental weapon's discharge cuts it in half. Given its inertia and the fact that at least one of the engines/screws would still be turning, one or both parts of the ferry would still be moving forward. Spider Man's webbing would not have had to hold the two pieces together, it would have had to have done so while the two parts were still traveling forward. The film specifically shows the ferry at a dead stop in the water during the fighting on the deck which caused the accident. There is no way that this could have occurred.
(at around 9 mins) When Peter Parker mistakes Tony Stark's reaching for the door as a hug, it is right after Captain America: Civil War (2016)'s events (they're even recording an alibi video for Aunt May). Peter's right eye looks totally fine. However, after he goes inside, the time is at the post-credits scene from Captain America: Civil War, where Aunt May is giving Peter an ice bag, and his right eye clearly shows bruising. But bruising often doesn't happen right away. Who's to say the post-credit scene didn't take place a day after he got back? Not to mention with Peter's powers, his may not injure as easily as a normal person so a bruise could take time to develop.
(at around 1h 45 mins) When Peter pulls up the aileron of the wing of the transport plane, he caused it to turn to the left. In many entertainment-grade flight simulators, that would only cause the plane to roll to the left. But in reality, an aileron turn is common because of its fuel efficiency. As the plane banks, the wings' lift is directed toward the low wing's side of the plane, causing it to bank; more so if the elevators are pulled into a climb, as this plane was doing.
(at around 37 mins) Somebody having a weapon capable of cutting a ferry in half should be an obvious warning sign of a danger rising, but even after witnessing it, Tony makes no attempt to clash with the Vulture.
After Peter has had his first encounter with Vulture, he informs Tony about him and the weapons. Tony responds that there are people who handle this sort of thing. However, he also notes that this sort of thing is a little below the pay grade of the Avengers (being a member, this would include Tony).
On the Staten Island Ferry, FBI-agents show up and attempt to arrest the Vulture. Afterwards, Tony tells Peter that he is the one who called the FBI.

(at around 5 mins) When Happy is driving the limo in the opening scene, the gear shifter on the steering wheel is in Park.
(at around 1h 35 mins) When Peter hijacks Flash's car during the Homecoming dance to pursue Toomes, he drives off erratically and crashes through a line of bikes. In the next scene, the front end of the car on the left side where it hit the bikes is completely undamaged.
The Vulture wears a flight jacket, but not an actual G-force pressure suit. This means that during any of his numerous acrobatics while in flight and during his acceleration, he would be subjecting himself to Gs beyond what could be tolerated by a normal human without passing out. Without a pressure suit, the blood in his body would remain in his lower extremities during these maneuvers and he would remain unconscious until he crashed into an object or the ground.
(at around 12 mins) When Peter is watching himself catching a car during class on Youtube, the red bar is not moving and the Youtube play button shows the play button, not pause button even though the video is playing.
(at around 13 mins) Peter Parker's milk carton reads "Best by: July 8" yet the movie is set in September.
(at around 1h 13 mins) The Staten Island Ferry is transporting cars on the lower level. However the ferry hasn't transported cars since September 2001 after the 9/11 attacks.
(at around 2 mins) During the 2012 events at the beginning of the movie, a Caterpillar 926M Small Wheel Loader can be seen in the background. The 926M was launched in 2015.
(at around 3 mins) Early on in the film when Toomes and his crew are back in his shop after losing the cleanup job from the New York incident in 2012, a Coors Banquet stubby bottle that was released June 1, 2013 can be seen on a table.
(at around 1h 21 mins) When Tony is talking to Peter after climbing out of his suit he says ''different story, right? Because that's on you''. His mouth movements don't match.
(at around 6 mins) During the Captain America: Civil War (2016) opening recap video montage supposedly filmed on Parker's phone for YouTube. A close up of the sleeping Happy Hogan reveals a reflection of the camera. It's not a phone but a shoulder mounted movie camera.
(at around 14 mins) During the first scene at the sandwich shop (located in Queens), a MARTA bus (the city of Atlanta's public transit system) can be seen driving past the shop.
(at around 1h 24 mins) When Peter is participating in the Spanish Class and produces a correct sentence, the teacher says "Muy Bueno" instead of "Muy bien" which is the proper sentence use to say something has been done correctly.
(at around 1h 21 mins) Following the Staten Island Ferry events, Tony says to Peter things about "what if somebody had died out there tonight?" He should have said "today" instead; this all clearly happened in broad daylight.
(at around 12 mins) One student is dressed in a military (ROTC?) uniform and is wearing his cap inside. This would be against regulations and the kid would know not to wear the cap in class.
(at around 44 mins) Peter later tells Ned that he had been dropped in a lake the first time he met the Vulture. However, when Spider-Man had hit the water, the George Washington Bridge can clearly be seen in the background making the body of water he fell in the Hudson River.
