While driving on the highway, the panoramic sunroof on my vehicle suddenly shattered out of nowhere leaving small shards of glass on the rear seat. It sounded like I was getting shot at as a loud pop caused me to almost swerve off the road before I pulled to the side of the road. My passenger, who was in the front passenger seat, informed me that sunroof had just randomly shattered. I made my way to my residence and call VW Customer Care immediately. I was informed to take my vehicle to my local VW dealer and have the issue diagnosed and that it should be covered under warranty. I took my vehicle to my local VW dealer first thing the next morning for diagnosis. After they documented the issue they sent the information to VW Customer Care for review. After having my vehicle for several days, I was contacted my local VW dealer who stated that VW corporate will not be covering the sunroof issue and that the repair would cost in excess of $4,000.00 to repair. I have contacted VW corporate numerous times since, looking for an explanation as to why this was denied but have been unable to speak with a Customer Care Rep via phone. I have been getting the run around that they didn’t have the right phone number for me which know a lie. My VW account is very clear and had my cell number listed. Today I received an email from VW Customer Care that they will not be covering the sunroof issue because they feel that it was not a manufacturer defect. This is also a lie. Sunroofs just do not shatter out of nowhere. It has been well documented in numerous class action lawsuits against VW and online internet posts, on such websites as Reddit, that VW has major issues with these panoramic sunroofs leaking and shattering out of nowhere. This is through no fault of the operator. I feel that a thorough investigation is warranted in regards to these defective sunroofs before someone gets seriously hurt or killed while driving one of these vehicles.
