My Venga 2018 has a large gap between the top of the windscreen and body, it is now rusting along the gap. There are no chips anywhere on the windscreen or anywhere else on the body. My Kia dealer tells me it is stone chips, when I asked where are they and why is there no damage anywhere else he could not answer that. This my third Kia and the only one that as rusted. In fact it must be over 40 years since I had a car that rusted. Has anybody else had this problem?
