Isuzu KB Xrider 2017

I bought my Isuzu KB Xrider in August 2017 at our local Isuzu dealer, where lucky to skip the long wait, but from the first I got some isues, the front bumper do not lined up on the left, a noice from the tyres or bearings or diff, but complaining the local dealer fix the bumper with new bumper clips, looks better but still not perfect like the right front. After alot of complaining the local dealer found that the problem is the tyres, but there are nothing they do because there only 3 custumers complaining from two dealers. After not accepting the story I took my complain to Isuzu head office, not very helpfull, there excuse where the 18in AT tyres are commin to have a road noice, and that there are no problem with the tyre, no body at the dealership took the tyre off to inspect, only promises that they will look into the problem. Did less then 20 000km in a year, cause it is unpleasant to drive.
