When Pilot was 2 years old a front windshield crack appeared at the bottom of the windshield directly in front of the center passenger seating position. No chip or hit to the windshield occurred and the crack actually grew from the bottom of the windshield where it is protected by the hood and appeared on a cold night while vehicle was parked. The body of the Pilot must have flexed at this spot and the crack is still there for inspection. My coworker has this same make, model, and year Pilot and his window also cracked in a similar fashion. I also have observed similar Pilots with the same crack. Since windshields are a vital structural part of the vehicle, I am concerned that Honda dealers deny that there is any defect when there absolutely is.
