While traveling on a highway entrance ramp, the glass of my moon roof "exploded" spontaneously. At the time of the incident (approximately 12:00 pm est), the temperature was around 30 degrees fahrenheit and there were no adverse weather conditions, I was traveling under no overpasses, and there were no vehicles in front of me. I noticed no objects striking my car before or at the time of the incident, my passengers and I only heard a noise that we agreed sounded like a gun shot coming from above the vehicle. Since I happened to have the sun shade closed over the moon roof, no glass entered the interior of the vehicle, but a significant amount of the moon roof (approximately 2/3) blew towards the back of my car and onto the highway ramp. Since I was traveling with my wife, mother, 5 year old daughter, and 2 year old son, this incident poses a significant safety hazard because if I hadn't had the sun shade closed, all passengers would have been exposed to flying debris from the blown out glass. I am confident that no objects struck my car to breach the moon roof, I strongly feel that this was a failure of the vehicle/component itself.
On 4/17/09 at about 2pm, I was traveling in a 2007 Hyundai Sonata southbound at 70mph on I-75 in florida between sr64 and sr70. Smooth traffic flow, no road hazards, bumps, potholes or debris. Weather 80 degrees, overcast. I had my ac on, windows closed and sunroof/sunshade closed when "boom" I heard an explosion above my head followed by the sound of wind. Startled, I immediately pulled over, got out and saw that my sunroof had literally exploded upward, with the shattered rim edges intact. Thank god I had my sunshade closed or I might have had glass fly into my eyes, blinding me and causing a catastrophic accident. I drove home and put a tarp on it because it was overcast and I was afraid of rain damage. I have used the sunroof on almost every day without incident, grinding noise, leak or concerns of any kind. I sincerely believe that this sunroof explosion was caused by a structural or mechanical defect from the manufacturer that could have lead to a serious, possibly fatal, accident. I am taking photographs and will be taking the vehicle to a Hyundai dealership for evaluation.
