Carrier/rack problems of the 2014 Mazda CX-5

Complained to Mazda that my driver side window rattles when driviing and driver side mirror shakes at 50 miles per hour. They told me there is no recall. Also I got a stress crack in my windshied started from bottom of windshield in the middle and turned right. The car was parked and in my driveway when this happened.

2014 Mazda cx5, heard a pop and noticed the windshield was cracked. The crack started from the base, center of windshield, and traveled vertical approx 12-15 inches. There was no rock or gravel strike, no visible chip. This is a recurring issue with other Mazda cx5's.

When I got in my car I noticed a mark in the center of on my windshield just under the rear view mirror. I realized it was a crack and when I got out to inspect it discovered that is was about 6 inches. It was hidden from the inside by all the rear view mirror attachments. I couldn't locate where something had hit the windshield. The safelite tech who came out to see if it needed to be repaired or replaced said she had never seen such a clean crack and said it was too large to repair. I was unable to get it replaced before going out of town for several weeks. When I got back the crack had grown another 12 inches just while sitting outside. It was in the sun for part of each day. The technician who replaced my windshield ran a ball point pen down the crack and it did hit a spot that apparently was from something hitting the windshield, but you couldn't see it just by looking. The number of instances of this happening makes it appear that Mazda is manufacturing inferior windshields. I have never seen or heard of a windshield that would crack that rapidly or cleanly.
