2017 RX350 F Sport Panoramic Sunroof
 

Has anyone had to replace the sunroof glass? The back sunroof glass shattered, and I strongly believe its a defect or Lexus is denying issues with the glass. No road debris hit the glass and it shattered in the driveway and its like it imploded inwards. I live in the south and its been unseasonably hot lately. But once again Lexus says heat is a external factor that they do not warranty.

Lexus here quoted over $6,000 to replace the shattered back glass.
