NHTSA Complaint #10231063 — 2006 SCION XB

WHILE DRIVING, A CRACK BEGAN IN THE WINDSHIELD COMING UP FROM THE ABOUT FROM THE BOTTOM OF THE WINDSHIELD (ABOUT 8" FROM THE MIDDLE, CLOSER TO THE DRIVER). AFTER CLIMBING A ABOUT 9" IT MADE A 90 DEGREE TURN AND CONTINUED ON (MAKING ABOUT AN 18" CRACK W/IN AN HOUR). THERE WAS NO CHIP NEAR THAT AREA. THERE HAD BEEN A CHIP ON THE FAR PASSENGER SIDE THAT HAD BEEN REPAIRED. SINCE THEN THE WINDSHIELD HAS GOTTEN 4 OTHER ROCK CHIPS (INCLUDING ON THAT CAUSED A CRACK EXTENDING EXACTLY OPPOSITE OF THE 1ST CRACK -- COMING FROM THE TOP-PASSENGER SIDE OF CENTER, TOWARD THE DRIVER). THIS CAR HAS ONLY BEEN ON THE INTERSTATE FOR ABOUT 2000 MILES (IT HAS A TOTAL OF 20000 MILES). IT HAS NOT DRIVEN ON ANY ABNORMAL OR INDUSTRIAL ROADS (ALL CHIPS/CRACKS OCCURRED WHILE THE VEHICLE WAS TRAVELING ON AN URBAN INTERSTATE AT SEPARATE TIMES). I WOULD ALSO LIKE AN ASSESSMENT OF HOW MANY CHIPS/CRACKS CAN OCCUR BEFORE A CATASTROPHIC FAILURE OF THE WINDSHIELD. AS I WILL NOT REPLACE MY WINDSHIELD WITH EVERY OIL CHANGE (ONLY WHEN THE STATE FORCES ME TO DUE TO THE FREQUENT NATURE OF THESE INCIDENTS). *TR
