2011 Mazda Mazda3

From 2000 through 2017, Takata produced millions of air bag inflators using two types of phase-stabilized ammonium nitrate ("PSAN") propellant -- propellant 2004 and propellant 2004L. After prolonged exposure to high temperature cycles and humidity, inflators using propellant 2004 can degrade, causing the propellant to burn too quickly when ignited. The rapid burning can cause the inflator to rupture during deployment, potentially causing serious or even fatal injury to vehicle occupants. See 2016 Blomquist Report at www.nhtsa.gov/sites/nhtsa.gov/files/documents/expert_report-hrblomquist.pdf.Consequently, all frontal inflators using propellant 2004 that do not contain a "desiccant" (a substance that traps and holds moisture) in US vehicles are under recall. These "non-desiccated" inflators either have been or are required to be replaced.In some cases, the remedy part for these recalled inflators was, or will be, an inflator using either propellant 2004 or 2004L that does contain a desiccant. None of these "desiccated" remedy parts (which were installed in older model year vehicles) are currently under recall for a degradation concern. Certain subsets of desiccated PSAN inflators using propellant 2004 for use as original equipment, however, have been recalled for a degradation concern. All Takata inflators produced with propellant 2004L contain desiccant, and none of these desiccated inflators using propellant 2004L are under recall for a degradation concern. There have been no reported field ruptures in any non-recalled desiccated PSAN inflators.It is understood that desiccants fully saturate at some threshold, at which point any additional moisture will not be captured. This means the degradation process observed in non-desiccated inflators using propellant 2004 may also occur in non-recalled desiccated inflators using propellant 2004, assuming additional moisture enters the inflator and high temperature cycling occurs. Based on available information, desiccant saturation can occur within the first five years in the worst environments, and the time required for full saturation is affected by multiple factors. While no present safety risk has been identified, further work is needed to evaluate the future risk of non-recalled desiccated inflators using propellant 2004.Three entities -- Takata (now known as TK Global), the Independent Testing Coalition, and Exponent -- have been studying the long-term behavior of Takata desiccated PSAN inflators using propellant 2004L (as well as 2004) in the presence of moisture and temperature cycling. The research efforts, which include development of predictive modeling techniques and field sample analysis, are ongoing. To date, none of the researchers have identified field evidence showing that propellant 2004L is undergoing a degradation process that leads to aggressive deployment and potential rupture. However, the time in service of such inflators remains short compared to that of the inflators using propellant 2004. Further study is needed to assess the long-term safety of desiccated inflators using propellant 2004L.The Office of Defects Investigation is opening this investigation to examine whether a safety defect related to propellant degradation exists in non-recalled desiccated PSAN frontal inflators manufactured by Takata. This investigation will require extensive information on Takata production processes and surveys of inflators in the field. Lists of recall actions that may have used desiccated PSAN inflators as remedy parts, as well as the makes and models originally manufactured with them, is available with the downloadable version of this document (see nhtsa.gov/recalls?nhtsaId=EA21002 -- note this information is subject to change/revision as the investigation proceeds). This investigation does not supersede EA15-001, which remains open.

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.

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!!!

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.

The car is jerking and check engine light is on. Also when you are stopped and press on the gar it takes a bit to get speed. The transmission control module needs to be replaced. There seems to be this issue on many mazda's just not sure why a recall hasn't been done for this case.

Defective Driver's seat construction made by Mazda Mfg Corp. I was the first person to report this cheaply made driver's seat failure to Mazda Corp in Irvine, CA in early 2015 or 2016. Recall was finally issued a year afterwards because Mazda dragged their feet, and only after I threatened to sue them if I was ever in an accident, and the seat was to totally fall apart, and maim me for life did they finally take action. The Recall fix (cheap bandaid clamp that again failed because seat frame welds had failed as well) was never done right, and as a result the seat totally fell apart, and Ed Howard Lincoln Mazda of Sarasota, FL didn't want to do anything further at that point (cost out of pocket wise). I was told by a different Mazda Dealership in Ft Myers, FL that that defective seat should have been totally replaced if they would've handled it correctly. So Ed Howard Lincoln Mazda really screwed me on that one! As related to the 2.5L Mazda engine, I also had/have a engine failure part there as well. It's called the ENGINE COOLANT (WATER) OUTLET FLANGE, and the bottom left hand bolt (1 of 4 bolts total) that's suppose to hold this cheap plastic part in place was stripped (over-torqued) at the production assembly line time that the engine was made (put together). Now the cheap plastic replacement part is leaking again from the same lower left hand corner, and this is a well Known Ford & Mazda 2.5L engine failure design as stated in many a Mazda online forum! This also should have been recalled, as now my 2011 Mazda 3 is down again. Engine overheated again on Oct 13, 2023. Prior repair to replace this defective Flange was done in Feb or Mar of 2022. Cheap Plastic parts put on a Metal engine just don't work well at all. Common Physics would tell you that! I have documents in my storage unit if you need them.

My seat lifter broke causing the driver's seat to rock back and forth. I brought my vehicle to my local dealer on 05/18/2022 to have an outstanding NHTSA recall 17V-082 performed to repair the issue. I was informed that the necessary part to repair the seat was on backorder and there was no ETA, but that I would be contacted when a part was available. Over the following nine months, I periodically followed up to see if they had received the part, culminating with being told by the dealer on 03/02/2023 that the part order was canceled and flagged as no longer available and that I needed to contact Mazda directly. I then called Mazda, who told me that the part was indeed marked as retired and advised that I seek an aftermarket replacement, of which none is available. They did check in my local area and found only one remaining part in a dealer's inventory, which I'll be driving to on 03/11/2023 to have the repair done. There has been no consideration made by Mazda for my safety while driving the vehicle, and for anyone still requiring this repair, the part is "retired" and no longer available from Mazda for an open recall.

A musty/mildew type odor may come from the vents when the air conditioning (A/C) system is operating. It is most noticeable when the A/C is first turned ON. This odor is the result of mold growth in the A/C evaporator/cooling unit which is caused by condensation, dust, and pollen within the cooling unit. This condition is usually worse during high humidity conditions. “Mazda Air Cooling Coil Coating” is available to encapsulate the mold to reduce odors. If the product is properly applied, it can effectively reduce the musty/mildew odor for up to three years. NOTE: See parts information for Mazda Air Cooling Coil Coating and Kit part numbers.

Some vehicles may experience exterior trim heat damage such (melted, separating, etc.) when parked near a glass building or Low-E windows. This may be caused by the sun's reflection. If a structure's windows create enough of a curve, the concave glass can focus the sun's rays onto a small area and acting like magnifiying glass direct the sunbeams into a hot pinpoint of light. This magnifcation of the sun's rays can cause damage to vehicle trim (see examples). Additional information and exemplar images regarding this phenomenon can be found by performing a google search.
