AS I CLOSED THE TAIL GATE THE REAR WINDSCREEN EXPLDED OUTWARDS RESULTING IN MINOR CUTS AND ABRASIONS ON FACE,NECK AND ARMS. THE WHOLE WINDSCREEN JUST SHATTERED FOR NO REASON. WHEN SAFELITE CAME TO REPLACE THE GLASS THEIR TECHNICIAN ADVISED THAT THIS IS A KNOWN ISSUE WITH CHEVY VENTURES, I BELIEVE THAT GMC SHOULD PAY FOR THIS REPAIR AND NOT THE CONSUMER, COSTING $184.
