Isuzu not the brand it used to be!

Brand New Isuzu KB 250 D-Teq 4x4 12 000KM on the clock <br> On the 12/08/2015 crown wheel bolt was not fitted properly, came loose causing a massive hole in the diff. After lengthy delays the problem was eventually repaired under warranty. <br> <br> Last month my clutch plate seized, subsequently Isuzu The Glen expect me to pay R12 000 for the repairs? This is a brand new vehicle, what a joke, I expected more from Isuzu. Your feedback will be appreciated.
