1999 Toyota Sienna Wipers & Visibility Problems

I WAS DRIVING AT APPROXIMATELY 35 MPH AND THE LEFT, REAR WINDOW BLEW UP. THE GLASS SPEWED ALL OF THE BACK OF THE CAR. LUCKILY, I HAD JUST DROPPED OFF MY KINDERGARTER AT SCHOOL AND NO ONE WAS INJURRED. I CALLED THE POLICE AND HE SAID IT DIDN'T LOOK LIKE ANYTHING HIT IT. HE SAID THAT SOMETIMES WHEN THE WINDOW SLIGHTLY OPENS LIKE THIS ONE DOES WHEN I PUSH THE BUTTON IT MAKES THE WINDOW WEAKER. I DIDN'T HAVE THE WINDOW OPENED AND IF THAT VENT MAKES THE WINDOWS EXPLODE, THEY SHOULDN'T BE INSTALLED IN THE CARS WHERE CHILDREN AND OTHERS CAN BE HURT. IF ANYONE WAS SITTING IN THE BACK, THEY COULD'VE BEEN SERIOUSLY WOUNDED. IS THERE ANY OTHER REPORTS OF THIS HAPPENING WITH BACK AUTO WINDOWS IN MINI VANS? NOW I'M AFRAID THE OTHER SIDE WINDOW IS GOING TO BLOW AND HURT SOMEONE. DT

WHILE DRIVING AT 35 MPH DRIVER'S SIDE BACK WINDOW SHATTERED WITHOUT WARNING. PLEASE PROVIDE ANY FURTHER INFORMATION.*AK

WHILE STOPPING AT A TRAFFIC LIGHT REAR WINDOW EXPLODED WITHOUT WARNING INTO LITTLE PIECES, THAT SHATTERED COMPLETELY. THERE WAS NO COLLISION INVOLVED TO CAUSE THIS. CONSUMER FELT THIS WAS UNSAFE BECAUSE CHILDREN WERE PRESENT.*AK

I NOTICED DISTORTION WHEN LOOKING THROUGH THE WINDSHIELD. DELRAY TOYOTA REPLACED THE GLASS TWICE. THE DISTORTION IS STILL THERE, BUT YOU SEE IT IN DIFFERENT AREAS OF EACH NEW WINDSHIELD. THE DEALER THINKS I MIGHT GET A GOOD PIECE OF "AFTER MARKET" GLASS SINCE EACH OF THE WINDSHIELDS SUPPLIED BY TOYOTA HAS THIS PROBLEM. THE WINDSHIELD LOOKS LIKE IT WAS MOVED BEFORE IT CURED PROPERLY. THIS GIVES A "MELTED" APPEARANCE TO THE GLASS. SOME PEOPLE MENTION THE REFLECTION FROM THE DASHBOARD CAUSING A DISTORTION PROBLEM, BUT THAT IS EASILY NOTICABLE AND NOT WHAT I AM DESCRIBING HERE. *AK

REFLECTION OF THE DASHBOARD IN THE WINDSHIELD CREATES A DISTORTION WHICH IMPAIRS VISIBILITY, AND COULD RESULT IN A COLLISION. *AK
