2012 QX56; this morning I noticed a crack in the windshield that was not there the night before (it is noticeable enough I'm sure I would have noticed when parking in the garage). There is not any appearance of a rock or other debris that would start the crack. Looking from the front of the vehicle the crack begins at the top of the windshield where it meets the chrome strip, slightly to the right of the rear-view mirror, runs down about 6 inches, then left toward the passenger side about 12 inches just left of the rear-view mirror mount. The entire crack is inside the black/dark shaded upper part of the windshield (embedded antennae?? or sun block? whatever it is
).
Has anyone ever had this problem? I plan to take to the stealership Monday and hopefully a windshield defect. Has anyone otherwise had to replace a windshield? Repaired by stealership or independent glass shop? Cost?
