On December 13, 2025, my vehicle (2021 Mazda CX-30) was serviced at a Valvoline Instant Oil Change location. During service, the technician stated he was checking tire pressure and asked whether 36 PSI was acceptable. I agreed. When I pulled out of the bay, the tire pressure warning light remained on and showed 29 PSI. I stopped immediately and informed the technician. He then stated he could not inflate the rear-left tire because he could not remove the valve stem cap due to corrosion. This was not disclosed before the vehicle was released. The technician told me I should drive the vehicle anyway and suggested I try removing the cap myself using pliers. No written warning or safety notice was provided. On December 16, 2025, while traveling on Interstate 81, I heard a pop/rattle and the vehicle became progressively louder. A warning displayed: “TPMS Malfunction. Have the vehicle inspected.” I continued driving until I could safely exit. The tire was shredded by the time I pulled over. The incident appears consistent with progressive deflation/underinflation leading to tire failure. The vehicle was released for highway operation despite the technician’s stated inability to service the tire at the valve stem.
