Have they had any hailstorms there local where the dealer is? That could happen if the glass was replacement before the cars sold.
I know at least 30 owner of the new altima has the same issue they just woke up and found the windshield broken no hit nothing and the dealer in my country replace it under the warrentyMy wife and stepson both bought new 2020 Nissans a few months back. She bought an Altima and he bought a Kicks. They bought their vehicles from the same dealership, same salesman at the same time.
Not a month after having their cars, the windshields cracked, starting from center top and quickly worked its way down. Both of these cracks happened on different days, but while the cars were parked. In both windshields the crack started top center and went down.
Called the service department at the dealership and of course they say they've never heard of this happening, which I don't believe. But basically, they won't cover it.
Has anyone else experienced this with Nissans windshields???
