NHTSA Complaint #11697100 — 2017 HYUNDAI SANTA FE

SPONTANEOUS PANORAMIC SUNROOF EXPLOSION - SERIOUS SAFETY DEFECT On October 12, 2025, at approximately 10:00 PM, while my 2017 Hyundai Santa Fe Sport was being driven on Interstate 85 near Greenville, South Carolina, the panoramic sunroof spontaneously exploded without any external impact or warning. What Happened: - My son was traveling at highway speed in normal driving conditions and he said it sounded a shotgun being shot at close range. The explosion created a period of dangerous distraction. - There was NO impact from road debris, rocks, or any external object - The sunroof suddenly and violently shattered, making a loud explosive sound - A few tempered glass fragments entered the passenger cabin, by the vast majority blew out of the vehicle. - The incident created an immediate safety hazard for vehicle occupants and for other vehicles who may have been following. - Visibility was not compromised, but due to glass exploding, my son had to drive on the shoulder of the Interstate at a slow speed with his hazard lights on in order to make it safely to an exit. Safety Concerns: - Sudden Loss of Structural Integrity - The sunroof exploded outward without warning - Glass in Passenger Cabin - Tempered glass fragments fell into the vehicle, endangering occupants - Driver Distraction - The sudden explosion and noise created a dangerous distraction at highway speed - Visibility Impairment - Glass debris and the sudden opening affected visibility - Weather Exposure - Immediate exposure to wind and weather elements at highway speed - Ongoing Safety Risk - This defect affects thousands of vehicles still on the road What Did NOT Happen: - No collision or impact with another vehicle - No road debris struck the vehicle - No rocks or projectiles hit the sunroof - No hail or weather-related damage - No recent sunroof operation or manipulation - No aftermarket modifications or repairs This was a spontaneous failure of a defective component during normal vehicle operation.
