Death Wish on Tantalus Mountain - S5-E2
Character mistake: McGarrett tells Pereno that the sabotaged race car went over a cliff. But the car crashed into a wall, with no cliff in sight. It's very unlike Hawaii's top cop to get the facts wrong - especially when he was an eye witness to the event. (00:44:00)
'V' For Vashon: The Father (2) - S5-E10
Character mistake: Hayward tells Vashon that McGarrett's office is on the third floor of the Iolani Palace. Previous episodes have placed the office on the second floor, or have shown the palace to have only two floors. (00:31:45)
'V' For Vashon: The Father (2) - S5-E10
Character mistake: Chin and McGarrett call the bomber Marcos, but his name on the social security card says Macros and Vashon calls him Macros.
'V' For Vashon: The Patriarch (3) - S5-E11
Character mistake: When Ben talks to the old guy about Spider Brown, Ben says, "Somebody that got rich the past week." The time between the shooting and trial was probably months, not just one week. Spider would have been flashing money right after the hit, and then disappeared.
The Clock Struck Twelve - S5-E12
Character mistake: After distracting the guards, Danno tosses a grappling hook onto a ledge and climbs the side of the building. He then goes about his business, carelessly leaving the hook and rope dangling from the ledge for all to see. For a seasoned 5-0 team member, that's pretty sloppy covert operations. (00:22:40)
Answer: He was fired. He never really appreciated his character. He felt Kono was portrayed as a big dumb Hawaiian and that the stereotype was racist. He also felt underutilized. He was fired after a heated argument with the show's publicist regarding his character. It seems there's not much details given regarding the incident or the firing, so it's seems possible he upset the show's producers as well.

No he said something derogatory about one of the Jewish producers that's why he was fired.
