2023 Volkswagen Tiguan

Driving long the interstate in South Carolina, all of a sudden there was a loud explosive sound and a crackling sound accompanied by the loud explosion. It startled me!! I gathered myself and put on hazard lights and got over on the far right lane to pull onto the shoulder of the highway. I thought that a tire or two had blown but was not the case. I got back into the car and started visually looking around to see where the crackling noise was still coming from. I looked up towards my Sunroof and discovered that a large hole in my Sunroof. Fortunately, my sunshade was closed and shield the debris/glass from spraying my face and body. I took the car to the V.W. dealership and explained the infraction to them. They diagnosed the problem and contacted me later that day to let me know that they were sending the request to V.W. corporate to get authorization to repair under warranty. The dealership did not detect any signs of rocks or debris causing the explosion. Corporate denied the dealerships request to repair under warranty. I filed the damaged Sunroof under my auto insurance. Im currently awaiting for the adjuster to inspect the damaged Sunroof that is at the dealership. I feel that Corporate dud not even consider the fact that this could have been an exploding Sunroof...and im sure that they have encountered this defect before. There are articles on-line of others who encountered this problem.
