2018 Chevrolet Silverado Visibility & Wipers 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.

TL* THE CONTACT OWNS A 2018 CHEVROLET SILVERADO 1500. THE CONTACT STATED THAT WHILE DRIVING AT 45 MPH, THE PASSENGER'S SIDE REAR WINDOW SHATTERED WITHOUT WARNING. THE CONTACT DROVE HOME AND IMMEDIATELY CALLED BOSAK CHEVROLET, BUICK, GMC (9911 W 300 N, MICHIGAN CITY, IN 46360) BUT WAS OFFERED NO ASSISTANCE. THE MANUFACTURER WAS NOTIFIED OF THE FAILURE AND DAYS LATER THE CONTACT WAS INFORMED THAT THERE WOULD BE NO ASSISTANCE SINCE THE VEHICLE WAS BEING REPAIRED THROUGH THE INSURANCE COMPANY. THE VEHICLE WAS NOT REPAIRED. THE FAILURE MILEAGE WAS APPROXIMATELY 7,500.

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.

2018 CHEVROLET 1500. CONSUMER WRITES IN REGARDS TO BLIND SPOTS ON PASSENGER SIDE MIRROR AS WELL AS SLOW ACCELERATION. *LD *JS
