Re: Windshield Cracking
What [MetalCooper] says is correct. The Tech Tip existed because Toyota was getting reports of cracked Sienna windshields while sitting on dealer lots. They issued the Tech Tip to get data and determine frequency of occurrence. Passing on owner data can only add to the sense of urgency to develop a repair procedure. There is no guarantee that it will fall under the warranty, but it may.
