My panoramic sunroof on my 2022 Hyundai Sante Fe spontaneously exploded today while driving down a county highway…the glass shattered and fell in (tempered glass failed completely resulting in a 18” x 20” hole and glass fell onto the retractable fabric sunroof cover, so not into the car itself). Likely due to heat, as there was nothing else around us. We were able to pull over and eventually get the vehicle to a dealership who put us in a loaner and said it will be fixed in 3-4 weeks. I alerted NHTSA, as I personally know of another Hyundai owner who had the same thing happen to his sunroof last week and the complete spontaneous failure of tempered glass does not bode well for safety in a rollover accident. When I called Hyundai from the dealership to file the incident claim, the customer service rep told me this was a known problem with the Hyundai panoramic sunroofs. I’ll never buy a vehicle with a panoramic sunroof again.
