2015 SUBARU IMPREZA Visibilitywiper Problems

My windshield cracked on its own, with no cause, chip, etc.

I HAVE HAD THIS VEHICLE FOR TWO MONTHS, THE MILEAGE IS 24K MILES. A SUNNY DAY, 42F, I INSTALLED NEW WIPER BLADES ON BOTH FRONT ARMS IN MY DRIVEWAY. I DROPPED THE PASSENGER ARM FROM ABOUT 2 INCHES FROM THE GLASS AND HEARD A ZIP SOUND. A CRACK APPEARED FROM THE BOTTOM OF THE WINDSHIELD EXTENDING ABOUT 6 TO 7 INCHES VERTICALLY. I DROVE THE CAR A FEW MILES FOR AN ERRAND THAT PRODUCED A CURVED EXTENSION TO THE CRACK MAKING IT ABOUT 18 INCHES TOTAL LENGTH. IT IS OBVIOUS THAT THIS IS NOT IMPACT-RELATED DAMAGE BUT INFERIOR GLASS. THERE ARE HUNDREDS IF NOT THOUSANDS OF SUBARU OWNERS WHO HAVE POSTED SIMILAR OCCURRENCES ONLINE. IN 2018, SUBARU LOST A CLASS-ACTION SUIT LAST YEAR FOR THIS SAME ISSUE INVOLVING 2015-2016 OUTBACKS AND LEGACYS BUT OTHER YEARS AND MORE MODELS ARE AT RISK. MY IMPREZA DOES NOT HAVE WIPER HEATERS AS DO...

IMPREZA WINDSHIELD CRACKED WHEN THE DEFROSTER WAS TURNED ON IN COLD WEATHER THE CAR WAS PARKED IN HOTEL PARKING LOT IN BOISE ID. IT WAS SNOWING OVERNIGHT AND THERE WAS ABOUT AN INCH OR TWO OF ICE ON THE CAR WINDSHIELD. TEMPERATURE OUTSIDE WAS ABOUT 20F. WE SCRAPED OUT THE ICE ON THE SCREEN AND TURNED ON THE DEFROSTER (BOTH FRONT AND BACK). WHILE DRIVING ONCE ALL THE ICE WAS MELTED, WE NOTICED A CRACK STARTING FROM THE RIGHT BOTTOM OF THE WINDSHIELD (NEAR THE PASSENGER SIDE). SUBARU DEALERS WERE NOT HELPFUL AND DIAGNOSED IT DUE TO ROCKS IMPACT, INSTEAD OF REPLACING THE WINDSHIELD THROUGH WARRANTY. THE CRACK HAS BEEN SPREADING EVER SINCE AND REQUIRES A REPLACEMENT (WITHIN 2500 MILES), COSTING $658. *TR
