NHTSA Complaint #11603292 — 2019 SUBARU OUTBACK

Severe windshield cracking requiring replacement. 2 in 6 month period. 1st was November 2023. Extremely cold temperatures. Cracked directly above heater vents on both sides same time. I watched it go from outer lower edges and move all the way to the center, entire length of the shield. I did not see anything hit the windshield, but they were iced and snow covered. I felt the temperature difference outside compared to in the cabin may have caused the crack. 2nd occurred July 12 2024. Extreme heat ( 100 plus) air-conditioning blasting cold air. Low traffic, at least 4 car lengths between mine and the car ahead. I did not see any debris. I did hear a noise, and then watched the windshield crack from the same location (lower outside edge) this time only the passenger side. The crack started approximately 6 inches. The following morning that crack had moved past midway of the windshield. This is not normal for any other vehicle I have driven. I have been driving 45 years. I have had a rock hit the windshield, some large rocks. In only one case I suffered a chip that was fixed with resin. There is a problem (safety) with this windshield. Installation, glass, design flaw?? I don't know the cause, but It is hazardous. The dealer's mechanic that replaced the 1st one told me "it is a KNOWN issue for my model" someone needs to address and correct an issue that is known which could be catastrophic. I was driving 35 mph in November incident, and 70 mph in July. I can provide documentation re: 1st replacement. I did not take pictures of that one. I can provide photos of 2nd one. I have not done 2nd replacement. I may just trade it out. That is how concerning this issue is to me.
