Within that volume, owners reported 12 crashes, 1 fire, 5 injuries, and 0 fatalities. For crash performance, NHTSA's New Car Assessment Program gave this cohort an overall 4/5 rating, with 5/5 front crash, 3/5 side crash, and 4/5 rollover scores derived from standardized barrier and dynamic tests.
Component-level analysis is where model-year complaints become actionable: the top complaint category for the 2012 MAZDA3 is power train with 38 filings, followed by engine (32) and exterior lighting (31). Concentration in one or two component groups is the classic signature of a systemic defect; a flat distribution usually reflects normal aging, warranty complaints, or isolated build-plant variability. This model year has 1 active recall campaign, which means the manufacturer is obligated to remedy the covered defect at no charge for the life of the vehicle — the full NHTSA campaign numbers are listed below.
NHTSA currently has 21 investigation files overlapping the 2012 MAZDA3, and 1 remain open. Owners comparing this cohort against neighboring years should pair the counters above with the complaint-by-year trend on the parent model page — a spike in a single year often tracks to a platform refresh, a new transmission supplier, or an updated ECU calibration.

The car leaks gas when the tank is full and if the car is inclined slightly. I've noticed the problem several month ago with an occasional odor but finally saw the gas leaking recently when it was parked on a sloped street.
The brake pedal is soft and sometimes unresponsive unless it is pumped repeatedly. There have been several times where I have been concerned if I would come to a complete stop. I have had both sets of brake pads replaced in the last year, and have on driven 9,000 miles. Two independent service centers diagnosed the problem as a faulty master cylinder. However, upon replacing the master cylinder and doing three brake flushes, and inspecting my brake pads and calipers, the problem persisted and is unresolved. They directed me to order a new ABS module, believing that that is the only other part that could be causing the cars brake problems. This part (BFY1437AZCO) is on backorder until November 2025.
The Seat Lifter on the driver's side seat frame broke, the metal has a clear stress fracture right near the bracket where the frame connects to the rail. This is the same part that was recalled in the 2010 and 2011 Models by Mazda in 2017. NHTSA Campaign No. 17V-082 It causes the driver side seat to change positions while driving creating hazardous conditions and does not appear structurally stable if involved in an accident potentially putting the driver's life at risk.
Our fuel tank is leaking for no reason. Brought it in last year (2024) for state inspections and let them know we smell gas when we park sometimes. They poke around and find nothing, but note there is a faint gas smell and to bring it to the dealer. We take it to Mazda to see if they can fix, they find nothing and charge my wife $250. Fast-forward to a year later, go for the same state inspection and we get failed. Our mechanic says theres a noticeable gas leak from the fuel tank and to take it to Mazda. There is clearly some issue with the fuel tank parts. The car itself only has 77k miles and it is 13 years old.
The contact owns a 2012 Mazda Mazda3. The contact stated that after refueling the vehicle, there was an abnormal gasoline odor inside and outside the vehicle for the next 5 days, prompting the contact to only fuel the vehicle halfway. The contact observed fuel leaking underneath the vehicle near the fuel tank. No warning lights were illuminated. The vehicle was taken to an independent mechanic, who diagnosed a failure with the welded fuel tank nipple fuel line connector. The contact stated that the component was cracked along the bottom of the weld. The contact was informed that the fuel tank needed to be replaced. The vehicle was not repaired. The manufacturer was not notified of the failure. The failure mileage was 81,000.
Mileage: 81,000
2012 Mazda3i 5dr hatchback. Persistent issue with headlights, both low beam and high beam, as well as interior lighting and other lighting. The headlights flicker for several seconds any time the brake pedal is applied. Interior lighting also flickers when brake pedal is applied. Headlights sometimes flicker when vehicle is decelerating and no brake pedal is applied, most notable when vehicle is traveling downhill. Further, the luminosity (brightness) of the headlights visibly dims, but does not flash, when the vehicle is parked and the brake pedal is applied. A high volume of others report the same issue, including documented complaints. These vehicles are unsafe, defective as designed, and do not conform to FMVSS No. 108. NHTSA must investigate further. Many other owners are not aware of the cause of the issue and attempt to fix it by replacing headlights, alternator, etc. Mazda was aware of issue prior to July 2013, when it issued TSB 01-019/13. This document states, "Some vehicl

The Mazda dealership reported to me the push rod was broken, that it âjust snappedâ. The car was towed by Zaben towing company courtesy of the auto insurance company associated with the vehicle to the Mazda dealership, however the towing company was on its way to another Mazda dealership per their app despite a clear address location given by the purchaser of the auto insurance. I found one of the hubcaps missing and placed in back seat of the Mazda after delivery and the Mazda not parked properly at Mazda dealership. The hubcap was not in back seat prior to the drop off. The clutch snap, as described by Mazda, did not happen while I was driving the vehicle. It was working perfectly fine two days prior to the discovery of collapsed clutch when I was driving around town. The clutch was found not working, collapsed after the car was parked for two days. Also, Texas Mazda dealership recommended another eight hundred dollar worth of work totaling near two thousand dollars yet I have b
Weak braking and spongy brake pedal created near accidents at highway speeds. Brake pedal needs to be pumped to get firmness. But the check engine warning light did not come on, either. So I had mechanics replace front rotors, front disc pads, and bleed/refill system with fresh brake fluid and inspect system for leaks. But spongy brake pedal problem was not fixed. So when I researched the problem on the internet, it appears that it's a systemic, long-time (10 model years or more) safety issue with Mazda that they failed to recall nationwide. Totally irresponsible. Among Mazda owners, after replacing all other brake system components and not solving the spongy brake pedal issue, it turned out to be a faulty ABS System Module, a $2,000 to $3,000 repair at Mazda dealerships.
Car started jerking and on the way home, the car lost all power to the transmission. The check engine light came on as well as the AT and traction lights. Absolutely no power to the transmission. codes P0780 and P0751.

My issue is with computer firmware updates the manufacturer (Mazda) needs to have done occasionally to help w/traction control and other issues, that the consumer is stuck paying for it, I had a check engine light come on and took it to the dealer. The dealer said that the TCM (traction control module)and the PCM (power control module)needed to be updated. And being the car was out of warranty that I was going to be responsible for paying $330. I would think that if a manufacturer decided to make new updates to help with safety and performance that it shouldnât fall on the consumer as we bought the car thinking they had this stuff already figured out. Like our smart phones when there updates we the consumer donât pay for the updates to help protect our phones from security issues and other thingsâ¦. So why is it acceptable for consumers to pay for auto industryâs updates to help with safety.
The dashboard of my 2012 Mazda 3 has separated from the instrument panel causing a gap between them. The dashboard has become very sticky leaving a black sticky film on the surface. This has caused a glare on the windshield making it hard to see at times while driving. There is a letter dated May 2017 from Mazda, Special Service Program (SSP) A9. The letter states that the warranty was extended 7 years (84 months) from the original warranty start date or April 30, 2018, whichever is later, with no milage limitation. As I read it, 7 years of 84 months from 2018 should extend the warranty for repair of replacement through 2025. Mazda refuses to make repairs, or replacement of this equipment that has an impact on the proper function of the airbag system and impairs the driver's vision because of the constant windshield glare. This is an issue. that needs to be addressed as an important safety.

[XXX] covers a safety oriented problem with my car. Jim Ellis Mazda in Marietta refuses to work on my car because it is more than 10 years old. This is a proprietary issue since it deals with the computer system in the car. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)
Headlight flickering and turns off and on randomly.
The car started to stall, hesitate and even stop completely for no apparent reason. The mechanic first recommended a new ECU/TCU which did not help the problem and in the course of duplicating the problem check engine light has come on for the transmission with problems shifting/sticking in a gear and not returning to first gear. My mechanic has stated that there is a known problem with Mazda3 transmission, and I should reach out to Mazda. They indicate there is no recall, but mechanic provided me TSB reference number 0500814 from a service bulletin. The car is a death trap and I have stalled while driving on the streets and freeway so obviously I can't drive the car. The car is still at the mechanics since parts cannot be found. Please help any way possible. Thank you.
My brake pedal became very spongy and soft after the ABS was activated. The brake pedal has to travel all the way to the floor to stop the vehicle. My rotors, pads and other brake parts are checked by experts and there is not any issue found with other brake parts. Even though the brake system is not working properly, there are no ABS lights on the dashboard. I risk an accident every day. I killed a squirrel because the brake system didnât work properly. Maybe one day I will die or cause to lose someoneâs life because of this braking issue. I started to be affected psychologically. I've read many complaints from Mazda users on forums about this problem. In subsequent investigations, Ford has recalled 600,000 2006-2010 Fusion, Mercury Milan, and Lincoln MKZ midsized cars to fix an ABS problem. The ABS valve reacts with the brake fluid currently used in the vehicles and can significantly slow or stop the action of the ABS valve, leading to braking problems. When I took my car to my m
