NHTSA Complaint #11642785 — 2022 VOLVO XC40

My car was sitting inside my garage, and just formed a crack, with no external disturbance. There is absolutely no way this was caused by external damage. You will see in the pictures that there is no external damage, and you can mainly see the crack looking up from inside the car. If you look at pictures of the glass, you see that the crack is on the underside of the glass, and that there is no single point of impact (like a radial crack, or chip, or anything on the outside surface). The Volvo dealership I took my car to said that even if it is a defect or an installation issue, that Volvo would do everything in their power to deny my claim. The dealer said they will document that that this was caused by external damage like a rock hitting the roof, even though I told them several times that the car was not being driven and was sitting inside my garage for months. I asked the dealer if they could show me exactly where the damage was, if they could point out to me where he initial outside impact or chip was. The dealership could not specifically point out where the chip was. I have contacted Volvo customer service and filed ethical complaints. They have more or less admitted to denying warranty claims on false evidence. It is also clear that the dealer gets paid more if it is not done through warranty, so they have no incentive to tell the truth (that this was a manufacturing/installation defect) I have done plenty of online research and found that many many other Volvo xc40 owners have the same defect in cars between 2020-2022 (their roof glass forms a horizontal crack completely unprovoked.)
