NHTSA Complaint #11510767 — 2022 VOLVO XC40

A series of large cracks have formed on the sunroof panel of the car. The cracks are on the top of the vehicle, and there have been no occassions of rocks or debris hitting the vehicle (which would have been noticed as it would've needed to be a direct hit straight from the sky). I live in San Diego and the car us usually garaged, so there have been no weather incidents to consider either. Plus, the cracks appear to be stress fractures as there is no spider-webbing type breaks which you would expect to see with strike. This same breaking has been noted by various other owners of this car on a forum (https://www.xc40forum.com/threads/crack-in-panoramic-sunroof.2403/page-3) including pictures of the breaks. In each case, it is the same glass panel directly on the top of the vehicle, the same side to side cracking near the front of the panel, and always Volvo says "it must be a rock strike". (Local Volvo service center said the same to me on 3/7/23). However, it seems very unlikely that everyone would be experiencing the same stress type cracking (not spider-webbing) near the same part of the panel, on the same panel, on the same type of car - AND that all were hit by a top down direct rock strike to that part of the vehicle without ANY other damage to any other part of the roof or hood. From the forum it looks like this has been reported by others to the NHTSA. My concern is that this panel will continue to crack until it potentially shatters glass on the occupants of the car, potentially while in motion which could present a risk to the occupants as well as others on the road. This should be addressed by Volvo at their expense, and given the consistency and growing number of reports should be addressed quickly before something much more dangerous occurs.
