I parked my car in my driveway everyday. In the morning, I found the front windshield cracked. I touched windshield inside and outside to check if it was hit by something, e.g. stone. The inside and outside surfaces of glass are smooth. Obviously, it was not hit. I have driven it for 3 years and 9 months, mileage is 42,000 miles. I owned 4 other cars before, some are used cars, some were brand new when I bought them. They did not have problems like this. This sienna was brand new when I bought it from the Toyota dealer. Although it was not covered by warranty, it has quality issues with the windshield.
