NHTSA Complaint #11620083 — 2020 VOLVO XC60

Good Morning: I've attached a letter that I've written to Volvo USA regarding their security lug bolts on the wheels of their vehicles and the adapter that they provide to remove this. I found out after incurring a flat tire that these adapters are often non-functional and that the dealer is well aware of this. I think this is an issue that Volvo should address for all current and past owners. Also, during this incident I experienced what I think is a flaw in their tire pressure monitoring system - it illuminated a yellow caution which, I've seen happen when one tire was not at the same pressure as the others. In this instance the tire was flat. Shouldn't that warrant a different indication? Thank you for your attention to this.
