On February 10, 2016, we were driving on I-25 headed to Arizona for a vacation. As we were just on the outskirts of Santa Fe, nm, we heard a loud explosion and it sounded like our entire car was blowing up. We were driving at 75 mph and there were no other cars close to us. We started hearing glass bouncing around on the sunroof curtain and realized that it was our sunroof that had exploded. We pulled into the first exit in Santa Fe and checked the car and the glass appeared to have exploded upwards. We drove to the next gas station and pulled out all the large pieces and vacuumed up what we could of the small pieces. Needless to say, we had to end our vacation and we turned around and drove home the same day. All we could hear on the way home was glass bouncing around and the road noise. We contacted GMC and they said we should claim through our insurance. Eventually, they relented and replaced the sunroof. I have done research on the internet and it appears that this is happening with many makes of vehicles not just gmcs. It appears there are some serious issues with sunroofs. If pictures are needed, we took several and I would be happy to provide. Thank you for addressing the issues with sunroofs. I no longer feel safe in this car and this is a vehicle that we purchased for road trips as we have two other vehicles which are our every day vehicles. It was the scariest thing we have ever experienced.

2015 GMC Yukon XL had been in service less than 4 months, only 5000 miles. Driver was driving 65 mph in moderate traffic on interstate 15 when the sunroof spontaneously shattered into tiny pieces. No airborne rocks or other debris was present that could have struck the window. About 4pm, weather was sunny, temperature mid 90's. the sunroof cover was closed which prevented most of the glass shards from entering the vehicle, but did scatter glass shards across the interstate.
