NHTSA Complaint #11687666 — 2011 MAZDA MAZDA3

The instrument panel above the information display in my 2011 Mazda3 has warped and created a visible gap, which is a known defect previously covered under Mazda’s Special Service Program A9 (SSP A9). While originally described as a cosmetic issue, in my vehicle the gap now allows engine odors and emissions to enter the passenger cabin. This condition presents a safety and health risk to occupants. My daughter drives the vehicle daily to college and is regularly exposed to these fumes. To confirm the problem, I used a Temtop M2000C Advanced Air Quality Monitor and recorded the following CO₂ levels inside the cabin compared to outside air: - Outside vehicle (baseline): 348 ppm - Inside after 1 minute: 436 ppm - Inside after 5 minutes: 1,027 ppm - Inside after 15 minutes: 1,645 ppm According to the monitor’s air quality guide, 1,501–2,500 ppm CO₂ is classified as “Unhealthy.” These readings indicate a measurable intrusion of emissions into the cabin. Mazda Customer Experience has acknowledged the vehicle is outside the SSP A9 warranty window and denied repair assistance, but I believe this issue is no longer cosmetic. The defect now creates a condition that may adversely affect occupant health and safety and should be considered under NHTSA’s authority for potential investigation. The vehicle can be inspected upon request. A Mazda dealer (Group 1 Mazda Denton, Texas) has provided a repair estimate of $1,307.77 for instrument panel replacement. Photos of the gap and air quality readings are available.
