2019 MAZDA MAZDA3 — Problems, Recalls & Safety Data

1. What component or system failed or malfunctioned, and is it available for inspection upon request? The airbag system, specifically the curtain airbags and related airbag control components, malfunctioned by deploying spontaneously without any collision or impact. The vehicle and deployed airbags are still available and can be inspected upon request. 2. How was your safety or the safety of others put at risk? The spontaneous deployment of all four curtain airbags created an immediate safety hazard. Airbag deployment can cause injury, disorientation, or loss of control, especially if it occurs unexpectedly. Although the vehicle was stationary at the time, deployment without warning posed a serious risk of injury to occupants and could have resulted in a crash if it had occurred while driving. 3. Has the problem been reproduced or confirmed by a dealer or independent service center? The problem has not been reproduced, as the airbags have already deployed. However, the spontaneous deployment itself is clear evidence of a malfunction. The issue has not been resolved or repaired, and responsibility for repair has not been accepted. 4. Has the vehicle or component been inspected by the manufacturer, police, insurance representatives, or others? The incident was reported to Progressive Insurance, which denied coverage because there was no accident or collision. The vehicle has not yet been inspected by the manufacturer for defect analysis. No police inspection occurred because there was no crash or injury. 5. Were there any warning lamps, messages, or other symptoms of the problem prior to the failure, and when did they first appear? Yes. The airbag warning light was illuminated prior to the incident, indicating a potential system fault. Additionally, a strong chemical odor was noticed inside the vehicle immediately before deployment, originating from the front passenger side, moments before all four curtain airbags deployed.

To whom it may concern, I was on a back road late in the evening not far from home [XXX] and a small deer ran into the road. I needed to brake to avoid hitting the deer. After breaking, a Brake System Malfunction warning message and i-ACTIVESENSE System Malfunction warning illuminated on my dashboard. I brought the car to a Mazda dealership the next morning. The technician determined that the brake fluid level sensor became stuck, requiring replacement of the brake fluid reservoir and the brake fluid level sensor. What failed: The repairs include replacement of the Brake Fluid Reservoir and the Brake Fluid Level Sensor. This is the link to the dealer report [XXX] . No one other than the dealer has inspected these parts to my knowledge. There was no accident of any kind. I personally felt unsafe after these parts failing and reached out to Mazda Customer Care to request investigation of the issue. The case manager just called me back today to say they could not help me. Mazda has denied warranty coverage, claiming the parts are not covered. However, I really do feel this is a critical safety system component that failed after normal emergency use with no collision or impact. Why I feel this is a safety concern: - The brake warning system became unreliable after a single emergency stop. - My car only has 42k miles and is in excellent condition and is fully dealer serviced. - A driver could lose the ability to receive proper brake system warnings if this failure occurs again. - A critical brake sensor should not fail under normal driving conditions, and its failure could lead to delayed driver response in an actual brake fluid loss scenario. It makes me worry for the future. For your consideration: I believe this represents a safety-related defect that should be investigated, as it affects the reliability of the brake system warning indicators in the 2019 Mazda 3. I appreciate your time and consideration. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)
