Factual error: Micaela was pushed off a cliff and landed on a ledge, and tells Zeke she has dislocated her shoulder. Zeke helps her get back to the top, and for the last push, she puts out both arms and Zeke pulls her to safety. Not possible. A person with a dislocated shoulder would not be able to move that arm.
Continuity mistake: In season 1, the pilot episode, the tail fin of the plane is blue with a white logo only. Starting season 3, the tail fin has "Montego Airways" written in red above the white logo. In most episodes, the tail fin is shown from the other side than the one shown in the pilot episode but in the last episode, when the tail fin falls in the water, you can see both sides with the red writing above the logo.

Factual error: Escorting Saanvi and her colleague to see Dr. Cooper, NSA Agent Tim Powell flashes a gold badge and shouts "NSA" to the officers. NSA agents carry ID Badges, but not gold shields. Further, they would never identify themselves as NSA personnel to outsiders.
Other mistake: Micaela and her partner are chasing an RV. A man from the RV throws a propane tank in her path. You can tell from the sound and how it bounces that it is empty. When the car hits it, the tank explodes, and she swerves the car into the brush and the airbags deploy. Later, as she is driving on the same road she gets a call that the RV has been spotted. Her car shows no damage. (00:17:44 - 00:29:10)
