If you suspect that something is wrong with your VX while it is still under warranty -- drive to your dealer ASAP. That's my advice, because once your over mileage or time they won't cover anything even if it's their fault.

As for the motor, Isuzu supposedly found an internal problem with some of the blocks from 1998 - 2002. Supposedly all the new motors have been changed to eliminate the problem. I don't have the details on exactly what the problem was, but as soon as I lost my engine I started searching the net for any information about this engine. There are alot more Trooper owners that have had the same problem with losing their engine with relatively low miles. I'm hoping that Isuzu did in fact change the block design because I don't want to drive another 20K to 60K miles and have to replace the motor again. I only have a 24K mile warranty on the new engine.
