On June 3rd, 2026, about 1:15 PM, I braked in the rain because there was a stopped car in front of me. The brakes did not work; the Automatic Emergency brakes did not work; the Forward Collision Warning did not work and I hit the car in front of me causing a 3 car accident. As I hit the car I saw the Forward Collision Warning come on and then go out. Unfortunately, the brakes worked after that and the Mazda Collision Center cannot find anything wrong with the brakes. I note that the 2022 and 2023 models of the same car did have recalls related to the brakes. The claim is still open and I have not yet received the final damage report. Yesterday I was told the revised estimate is $16,000 and my car and the middle care with front and rear and damage are considered totaled.

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.

Following a recent inspection at Perry Mazda in Santa Barbara, my vehicle was diagnosed with a failed clock spring mechanism causing airbag malfunction warnings. Clock spring failure under 70K miles on a 2021 vehicle is premature and suggests a defect rather than normal wear. I contacted Mazda North America and it has been over a week without a response. I have maintained the vehicle responsible and have no history of collisions or modifications that could have contributed to this failure.

The left and/or right side sun visor does not stay in the fully retracted position and may lower slightly due to its own weight. The problem is attributed to a broken connection point where the sun visor attaches to the vehicle. Impaired visibility, particularly in bright sunlight.

The climate control system suffered a sudden, complete failure due to an engineering defect documented in Mazda Technical Service Bulletin (TSB) ID: MC-10203760-0001. The factory evaporator core leaked refrigerant rapidly starving the A/C compressor of essential lubricating oil. This caused the compressor to overheat and complete seize. This failure occurred during extreme summer heat exceeding 100 degrees Fahrenheit, creating an immediate health hazard inside the cabin during my daily 40-mile highway work commute. Additionally, the complete loss of climate control functionality compromises the vehicle's defogging and defrosting capabilities, creating a severe visibility hazard during sudden weather changes on the highway. Mazda customer service corporate teams refused to cover or reimburse the repair because I had to utilize an independent repair facility (Firestone) within walking distance of my home to safely remedy the immediate environmental hazard. The manufacturer is actively denying financial accountability for a well-documented manufacturing flaw that leads to premature secondary component failure. No warning lamps, messages, or other symptoms of the problem prior to failure. First appeared 7/23/26.
