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)
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.
