I was driving it and randomly the AT and TC , and check engine light came on and the car went into limp mode, after doing some research it appears to happen to all 2009-2011 Mazda3's and it's a safety hazard. It's a safety hazard because of when it's stuck in limp mode sometimes if your at a light or something it'll start shifting and if you're not holding the brake completely down it will make the car lurch forward like 2-3 feet more if you don't react fast enough. This is a serious problem as it can cause a wreck. And you never know when it's going to happen there will be no symptoms it will just go into limp mode sometimes it'll rapidly go in and out and I'm sure that's causing damage to my transmission. Please make Mazda recall the TCM part and replace it. Thank you so much for taking the time to read my complaint/safety issue. Have a good day or night!!!

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 system failed to deploy during a major accident I was in, where my car rolled multiple times, and the collision that totaled my car. This includes the front airbags, impact sensors, and/or the airbag control module not activating. The vehicle is currently in the possession of the insurance company and can be made available for inspection upon request. During the crash, no airbags deployed, which significantly increased the risk of serious injury or death. The lack of airbag deployment left my partner and me completely unprotected at the moment of impact, including the number of times we rolled, seriously putting our safety at severe risk The vehicle is no longer drivable. The police report notes that the airbags did not deploy. The vehicle is in the process of inspection by my insurance adjusters as part of the total‑loss evaluation. The manufacturer has not yet inspected the airbag system, but the vehicle can be made available if Mazda requests an inspection. There were no warning lights, messages, or symptoms indicating an airbag or safety system issue before the crash. The airbag system gave no indication of malfunction before the failure occurred.

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.
