2010 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 AT light came on the dash, added transmission fluid because it was a little low but the light still has not gone off. I think there is an electrical problem within the transmission. It's had shifting issues since purchasing this vehicle. I also have a small child that comes with me to work and I do not want my car to catch on fire while we are in this vehicle.

my girlfriend had bought a car from a dealership in Pennsylvania and the car is registered in Pennsylvania at a dealer called premier world wide auto sales. when she had bought the car all four of the tires i believe should have failed pa safety inspection and the owner of this shop keeps telling me that they pass one hundred percent even though the tires have signs of dry rot all the way around all four tires and would not stop giving me problems and trying to prove me wrong the dot codes show that the tires in the front were 10 years of age and the rear tires at 8 years of age and showing signs of dry rot the tire size all around is 205/55r16 and this is completely unacceptable for a business that has been operating for as long as its been operating because all i can think about is how many other cars has this dealership sold with dry rotting tires nor did they show my girlfriend when she bought the car any of the work that had been done by the shop that had done the inspection prior she was told that everything on this car was great and that there weren't any issues when infact that was not the case i found a leak coming from an engine oil pressure sensor and a cv axle boot torn and flinging grease along with the tires with none of this being disclosed to my girlfriend who bought the car shortly after

NHTSA Complaint Narrative I am filing this complaint regarding a 2010 Mazda 3, VIN [XXX] . The vehicle experiences intermittent transmission control failures, including difficulty shifting out of first gear and warning indicators triggered by vibration. The transmission and transmission control module have already been replaced. The dealership has identified the wiring harness as the cause of the remaining failure. Mazda North American Operations has confirmed that the required wiring harness (BBM9-67-020H) is discontinued and unavailable. However, Mazda has not provided a written determination of whether the known wiring harness recall (engine wiring harness chafing affecting control systems) applies to this VIN, nor confirmed recall completion history. Mazda has advised the customer to seek aftermarket or salvage parts, but has not provided an approved repair remedy or goodwill assistance despite the issue affecting drivability and safety. I am requesting that NHTSA review whether Mazda has met its obligations regarding: 1.recall applicability determination by VIN, and 2.providing an adequate remedy when OEM repair parts are no longer available for a safety-related defect.

I have reason to believe the dealership I bought my vehicle from rolled back my odometer. Upon checking my carfax information, 12/01/24, the odometer read 161,142, which the dealership did own my vehicle at this time. When I bought this car in April of 2025, the odometer was reading 130,000.

On August 15, 2025, my 2010 Mazda 3 began displaying the ABS warning light intermittently while driving. The ABS system is a critical safety feature, and when the light comes on, I am unsure if the braking system will function properly in an emergency. I scanned the vehicle using a Foxwell diagnostic tool and retrieved the following ABS-related fault codes: C0020:1C-2B – ABS Pump Motor Control Circuit U0425:62-60 – Invalid Data Received from IPC/ABS Control Module U0140:00-28 – Lost Communication with Body Control Module These issues are consistent with Mazda Technical Service Bulletin 04-002/13 (July 17, 2013), which documents ABS pump motor failures caused by poor motor brush contact. This is a serious safety concern because the ABS system fails without warning, leaving the driver and passengers at risk of brake loss in critical conditions. Why this should be investigated: The defect occurs intermittently, making it difficult to predict or reproduce. It matches a known documented defect acknowledged by Mazda in TSB 04-002/13. Other owners have reported similar ABS pump failures in Mazda vehicles of this generation. The failure compromises safe braking and should be treated as a safety defect warranting investigation and possible recall. Action Requested: I am requesting that NHTSA investigate this recurring ABS pump/motor failure in 2010 Mazda 3 vehicles and determine whether a recall should be issued to address this known defect.

The a.b.s pump module is defective in these vehicles. There are tons of people having issues with them. When they fail it happens suddenly resulting in brake failure, power steering failure, the car does not like to shut off, the vehicle will go into "limp mode" and every light on the dash comes on. The part itself is costing close to $1000 u.s.d . With all of tge effected things tgat go with it i believe it can be very dangerous and should be recalled

This vehicle is subject to recall #: 17V-082 referring to a drivers seat lifter link than can break. My car has a broken lifter link, was brought to the dealership and instead of replacing the entire seat adjuster unit like the recall states, they simply installed a reinforcement bracket. When brought back to Med Center Mazda they state it has already been repaired and therefore cannot be repaired again. The vehicle still has a broken seat lifter link.

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.
