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.

What owners say
On July 1, 2025, I was involved in a severe rear-end collision while driving my 2024 Mazda3 manual hatchback. The impact was forceful enough to shatter the rear windshield, leave a deep dent in the tailgate, and bend the trailer hitch mount under the vehicle by several inches. Despite this, none of the airbags deployed, and there were no airbag warning lights before or after the crash. After the incident, I checked my vehicle’s VIN on the federal safety agency’s recall lookup tool and discovered that Recall 7525E had been issued on June 6, 2025, for a critical airbag sensing system defect (SAS module), which can disable airbag deployment after battery depletion or improper power conditions. According to Mazda and the federal safety agency documents, this defect can completely disable airbag function, increasing the risk of injury in a crash. As of July 11, 2025, I have not received any recall notice from Mazda by mail, email, phone, or dealer contact—despite being the registered owner. Mazda’s documentation shows that: Dealers were notified as early as June 3, 2025 Owner letters are not scheduled until July 28, 2025 This means that I was driving a defective vehicle without knowledge of a serious safety issue at the time of the crash. I believe that: Mazda failed in its legal obligation to notify me in a timely and adequate manner. The non-deployment of airbags in my crash is consistent with the failure described in Recall 7525E. Other affected Mazda owners may remain unaware and at significant risk. I respectfully request that the federal safety agency: Investigate whether Recall 7525E was the cause of airbag failure in this incident. Determine whether Mazda’s recall notification practices met regulatory requirements. Ensure immediate outreach to affected owners to prevent further injury or risk. I am also seeking legal counsel due to the serious safety implications and potential liability arising from this defect. I will be retaining all documentation, vehicle records, photos, and post-

Air bag warning light went on. Found Code B1126:13 Driver Side Airbag deployment. Replaced driver side air bag under warranty.
When I’m driving the car, electricity of the car goes off, including headlights. The steering wheel gets locked. It doesn’t do that regularly. Sometimes, it takes weeks to do that, but sometimes it happens once in every five minutes. The red airbag light on the odometer turns on or off randomly. But, the worse case is that the airbags are not working while my steering wheel gets locked at the same time. They all start happening around the same time. I took my car to the Mazda Service and another mechanics. Neither of them found the issue. When I leave the car with them, the car doesn’t show these malfunctions. It literally randomly occurs. Therefore, they told me that I need to bring the car when it start happening in regular basis to understand the exact cause for the issue. I don’t know when it becomes a regular issue. 4-5 days ago, when I was turning right on a small street, the wheel locked again. I was about to crash. It’s a deadly malfunction, so I don’t want to wait until then.

The airbag light keeps coming on flickering periodically as I'm driving. I'm very concerned about this airbag if it's going to deploy while I'm driving or if it's going to even deploy if I do get into an accident and if it's going to work or am I going to be killed if it doesn't deploy I'm very concern it's is safety issue.
