All the King's Horses - S2-E10
Audio problem: When McGarrett and Danno pull away from the curb in McGarrett's big black Mercury, the tire-squealing sound effect begins before the car actually starts to move. (Doesn't happen unless you're flooring it and "peeling out," which they're not.) (00:41:50)
Kiss the Queen Goodbye - S2-E25
Audio problem: At the Governor's pageant, a group of young children sings and dances to ukulele music. But the song is just a little too noticeably dubbed in: none of the kids' lips are moving. (00:30:10)
Audio problem: Probably due to poor sound pick-up outdoors so near the ocean, much of the dialogue on the beach house patio is noticeably overdubbed. The sound is often out of sync with the actors' lips. (00:39:00)
Audio problem: Throughout series: "Hawaii Five-O's" favorite sound effect was squealing tires, and the effect was nearly always added whether McGarrett's big black Mercury actually "peeled out" or pulled away at a normal speed. More than once, the tire squeal sounded when the car was sitting on beach sand. Nice trick - if you could do it. But alas, you can't "burn rubber" on a beach.
Audio problem: In the film left behind by the killers, the two men in the picture can be heard talking - but their lips aren't moving.
Three Dead Cows at Makapuu (1) - S2-E23
Audio problem: The landing jumbo jet's tires start making skidding noises before they've actually touched the ground. (00:13:45)
3,000 Crooked Miles To Honolulu - S4-E4
Audio problem: During McGarrett's second visit to question the professor, in the midst of their conversation, something off-camera makes a very loud thump. Professionals that they are, Buddy Ebsen and Jack Lord carry on with their lines as though nothing has happened. But this looks just a bit odd, because you wonder why their characters aren't curious about the noise. (00:34:10)
Mother's Deadly Helper - S6-E22
Audio problem: Chin says "Telex from Washington"; Steve says "Good, good". Clearly overdubbed. Watch - their lips don't move. (00:40:20)
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.
