While driving at approximately 20-25 mph, the panoramic sunroof glass of my vehicle suddenly shattered without any warning. There was no impact from road debris, no visible chip, and no prior damage to the glass. The glass appeared to explode outward, creating a loud noise and causing shattered glass to fall inside the vehicle. This created a dangerous situation that could have led to driver distraction or injury. Safety Concern: This incident poses a serious safety risk. Sudden shattering of the sunroof while driving can: Distract the driver and lead to loss of control Cause injury from falling or flying glass Create hazardous driving conditions, especially at highway speeds Dealer Response: I reported the issue to a Toyota dealership, but they denied warranty coverage, stating it was not covered without providing evidence of impact damage. Additional Notes: There was no visible point of impact, which suggests a possible stress fracture or manufacturing defect rather than external damage. Request: I request that NHTSA investigate this issue as a potential defect, as spontaneous sunroof glass failure while driving presents a significant safety hazard.

We were going down the highway in our brand new Grand Highlander yesterday (3500 miles, 3 months old) and it was like a bomb had gone off. The panoramic sunroof exploded up and out. Glass started falling on my daughter whom was in the middle seat. My husband had to quickly pull off the highway to safety. I have never experienced anything like this and it was extremely scary. Obviously there is a defect that needs to be addressed.
