It’s possible that your car has a windscreen that was manufactured with this defect. In some cases, automotive glass can either be manufactured with a lamination fault or can delaminate sometime after that due to a variety of factors.

It could also be that you’re dealing with a windscreen that has been damaged by flying debris. This can be caused when the vehicle is transported from the docks or warehouse to a dealership on the back of a truck. If the debris was the right size, it could virtually `sand-blast’ the windscreen, leading to the problem you’re seeing in particular lighting conditions. You might have noticed cars being transported by truck where the new vehicle at the front of the semi-trailer will have its glass taped over. This is why.

The first step is to have a windscreen specialist look at the vehicle to determine what the problem is. If it’s a manufacturing or transporting fault, you should be covered by the vehicle’s new-car warranty.
