I'm sure if you look at ANY auto manufacturer, even some of the most reliable, you will see engine or other major mechanical failures. On what percentage does it happen or? Who knows.

Isuzu DOES have a good reputation for high quality products in the past and present (although they tend to keep the same technology in use for a while). Now, I can't speak as to why there have been a few people, on this board even, that have had engine troubles... which could quite possibly mean that there could be the same percentage Isuzu owners driving vehicles with similar engines (Trooper, Amigo, Rodeo) having these problems as well. I haven't heard of many more cases outside of this board, so I don't know how common the problem is.

I must say, though, that just the number of people I have heard of here, on this forum, is enough to make me cautious.
