Upon returning from vacation, we found our moonroof had shattered. The vehicle was sitting in a parking garage at Logan airport in Boston for 7 days, with no evidence of any cause. The entirety of the glass was shattered and bowed up towards the center as if popping under tension. If the sunshade were open, shards of glass would have fallen upon myself and three children in the car. The description appears to match several other similar events described by other owners in previous NHTSA reports as well as online message boards.

As I was driving on the freeway the sun roof spontaneously exploded. Nothing hit the vehicle, there were no cars or trucks around me tossing debris and I was not under an overpass. Temperature was around 55 degrees, it was raining off and on throughput the day, not raining at the time of the incident.

Driving on a highway on 1/13/2023 and suddenly the sunroof exploded! It sounded just like a gunshot when it happened. Nothing at all hit the vehicle or sunroof, just a spontaneous explosion with glass going everywhere. Luckily there were no injuries to the driver from falling glass and we did not go into oncoming traffic on a two lane highway. It was extremely startling! This car only has about 8,000 miles on it, we bought it new in November 2021. I contacted the dealer where it was purchased. Fortunately they saw fit to repair it free of charge to us, and provide us with a loaner car.

Two days ago, my husband took our vehicle to the car wash. At the other end of the car wash, it was discovered that the closed panoramic sunroof was completely destroyed during the process. Shards of glass were everywhere. We have contacted Hyundai and they have told my husband there is no class action suit about this problem. Even though it is under warranty, as it is a 2022, they refuse to take responsibility to take care of the damages. I have found through my research, that this was a class action lawsuit, which was closed in 2017, but continues to be a very bad problem for not only Hyundai but many other vehicles using a particular type of glass. we are now unable to get the parts to repair it, as the glass company cannot get a part from Hyundai, and Hyundai refuses to comply comply.

The contact owns a 2022 Hyundai Palisade. The contact stated that while driving at an undisclosed speed, the sunroof glass exploded. There was no impact on the sunroof to have caused the sunroof glass to shatter. The sunroof screen prevented the glass shards from entering the cabin of the vehicle. The contact did not sustain any injuries. The vehicle was taken to the dealer where it was diagnosed that the sunroof glass needed to be replaced; however, the replacement part was not covered under warranty. The vehicle was not repaired. The manufacturer was made aware of the failure but informed the contact that the replacement part was not covered under warranty. The failure mileage was approximately 4,700.

On May 7, 2022 I was driving to Georgia to visit a loved one in the hospital at night. I was driving by myself with my dog. Approximately 1:50 AM, I stopped in Greensville, NC (my halfway point to my destination) to relieve myself, let the dog relieve himself, and fill up my gas tank for the 2nd time (which was 5 hours from my destination). Approximately 15-20 mins after getting back on the road, I opened my sunroof to smoke a cigarette and I hear a loud "boom" on the roof of my vehicle. I looked up to see if my roof luggage crossbars were still in place (and it was). I continued to drive. I finished my cigarette and began to close the sunroof when I heard another loud noise with glass falling into my vehicle. I looked up and noticed that my sunroof has shattered completely. I hit the S.O.S button for assistance and they asked me to pull over. I told they, "Absolutely not! This is not a well lit area; I'm driving by myself; it's just me and my dog; I don't know where I am; I'm in the middle of nowhere; I'm scared; and it's 2:00 in the morning!" I continued driving and told the operator that I was coming up on an area that looked better lit with signs showing food, lodging, and gas. I told her, I was going to get off the highway and go to one of the gas stations in that area. I took the exit and headed to the gas station; however, all of them were closed. I asked her what were my options? She stated that she wanted to send Roadside Assistance to my location and they would tow my vehicle to the nearest hyundai dealership. I told her that everything was closed and because it was so late and I was in the middle of nowhere, I would continue to my destination and call back. I continued to drive 5 hours straight (without stopping) to get to Georgia. During the remainder of my travel, I had to keep holding the sunroof cover because of the vibrations from the wind pockets to keep the cover from sliding and vibrating.

Sunroof shattered. We were traveling on I70 in eastern Colorado. The temperature outside was just below freezing and the temperature inside was set to between 72 and 78. We heard a loud bang and we were showered with broken glass. My wife, two sons and I received minor cuts. My wife possibly got some glass in her eye but seems to have gotten it out with no ill effect. While I was very startled I didn-€™t swerve. If I had, we would likely have lost control of the vehicle. We were traveling at freeway speeds and I think we would have been seriously injured or killed if this had occurred.
