I know it's not the biggest deal, but I find this sort of thing rather depressing. Windscreens are not novel rocket science, how does a manufacturer get to using an OE supplier with such a quality issue? Is it a departure from proven technology in manufacture or just poor quality control? These sorts of faults simply should not happen.
The latest Jazz models seem to be experiencing too many similar type of niggly issues (splitting seat material, delaminating steering wheel finish, scratches in paint, door mirror faults etc)
