20250224VISIBILITY/WIPER

I was driving in dense traffic at 55mph. The rear window suddenly, and without warning, exploded. Glass shards peppered my wife’s and my back neck. The window is protected by a headache rack (see pictures). My thought is the glass is improperly made, in that it should not explode; or improperly factory installed.
