2018 CHEVROLET SILVERADO 1500 Visibilitywiper Problems

My rear glass broke yesterday with my two year old daughter in the back seat. I was informed that there was a previous recall on this and its now closed. If you look in the attached photos you can see it appears the rear defrost is what caused it to shatter. The dealership is telling me that there is no recalls.

WHILE WAITING TO ORDER A MORNING COFFEE AT A LOCAL COFFEE SHOP DRIVE THRU (STATIONARY), THE REAR DEFROST/DEFOGGER CAUSED ONE OF THE GLASS PANELS OF THE REAR WINDSHIELD/BACK GLASS TO SHATTER/EXPLODE. THERE WAS ALSO SMOKE & AN UNMISTAKABLE ELECTRICAL BURNING SMELL PRESENT AT THAT TIME. PLEASE REFER TO GM CANADA RECALL N192220470, AS I BELIEVE THIS SHOULD BECOME A SAFETY RECALL IN THE UNITED STATES OF AMERICA AS WELL.

WHILE VEHICLE WAS PARKED, THE TEMPERATURE IN THE 30S-40S, I REMOTE STARTED IT TWICE TO WARM IT UP. WHEN I WENT OUT TO LOAD MY THINGS IN THE CAB, I OPENED THEN CLOSED THE BACK DRIVER SIDE DOOR AND THE REAR GLASS EXPLODED.

DRIVING WITH MY FAMILY ON A STATE HIGHWAY DURING A RAINSTORM AND THE FRONT WIPERS STOPPED WORKING ON ALL SPEEDS. THE SPRAYER STILL WORKED AND HAD RAINX. AFTER WE STOPPED AND ATE BREAKFAST THE WIPERS MADE ABOUT 3 PASSES THEN PARKED THEMSELVES AND HAVEN'T WORKED SINCE.

THE REAR GLASS SHATTERED WHILE DRIVING. NOTHING HIT THE WINDOW. I SHATTERED ON ITS OWN WHILE DRIVING ON A SMOOTH ROAD.

IN COLD WEATHER THE WIPER BLADES FREEZE AND DO NOT CLEAR THE WINDSHIELD CAUSING THE DRIVER TO NOT BE ABLE TO SEE OUT THE WINDSHIELD. EVEN WITH THE FRONT DEFROSTER ON HIGH, THE WIPERS BLADES FREEZE UP. THE WIPERS DO NOT HIT THE ENTIRE WINDSHIELD. DURING NON FREEZING CONDITIONS.
