The car is in a garage 90% of the time and is rarely used these days. The cracks don’t look like they are from impact of debris and resemble situations cited in the class actions.
Out of own experience (albeit with Toyota) - the service technician took a pen and followed the crack. Should there be no catch on the way along it it would be covered with warranty. A catch was indicating the location where the rock hit to start the crack. I don’t know how much of a real test is it but it may give you some early indication as to how realistic your warranty claim may be.
