2023 Subaru Outback

Sunroof spontaneously exploded. Temperatures were around 50 degrees, no cars around me at the time and as far as I can tell, nothing could have hit the window at least at that moment. I had been driving for about 1 hour and no sudden changes in temperature or pressure. It sounded very much like an explosion when it happened. Thankfully, the inside slide cover was closed when this happened. If the slide window cover had been opened, It could easily have caused an accident as some of the glass would have fallen on the driver. Also, the breaking window resulted in a shower of glass over the car roof and would have hit cars behind me if present. At the time, I had less than 3000 miles on the car and the car was less than 6 months old. The window has since been replaced. If you look at the profile of the car from the side, the sunroof seems to be more sloping downward than on some other cars. My understanding is that sunroofs are made from tempered glass. It would seem that safety glass would be a better option at least in terms of the protection they might offer in preventing the dramatic shower of broken glass that happened in my case.

Dear NHTSA, I am writing to report an issue I have experienced with the windshield of my Subaru vehicle. Recently, I noticed a crack on the passenger side of the windshield, which initially measured around 5 inches in length. To my surprise, the crack expanded to over 10 inches in just a day and continued to grow thereafter. Upon visiting the dealership, I was informed that the crack was likely caused by a small impact point on the windshield. However, I am not satisfied with this explanation as the "hit point" is extremely small and not commensurate with the size of the crack. I am also concerned about the quality of the Carlex windshield glass used by Subaru, as I have seen numerous complaints regarding the same on various websites. It is worth noting that Subaru does not allow customers to choose better quality aftermarket glass and refuses to perform recalibration if customers opt to use third-party glass. Furthermore, the Carlex glass costs approximately $1000 (without recalibration) and is of lower quality. I respectfully request that you investigate this issue further and take any necessary measures to address this problem for the safety of all vehicle owners. Thank you for your attention to this matter. Sincerely, [XXX] INFORMATION Redacted PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6).
