Each component in detail
What the reports in each category say, in the owners' own words
Electrical
Reports naming the electrical system — wiring, battery, charging, control modules, infotainment and electrical accessories.
From owner reports, verbatim
The contact owns a 2016 Mazda Mazda3. The contact stated that while driving and while starting the vehicle, the instrument cluster was inoperable. The contact also stated that the instrument cluster screen was peeling, and critical information for the vehicle was not displayed. Additionally, the infotainment system became intermittently inoperable due to the failure. The dealer was contacted; however, the vehicle was not diagnosed or repaired. The manufacturer was not made aware of the failure. The contact expressed concerns that the inoperable instrument cluster created a hazardous and unsafe condition due to the complete loss of instrument panel functionality. The approximate failure mileage was 142,000.
When I checked for recall information 2 recalls were listed under my car's vin #: Recall #1: 3219D with Closed status. Recall #2: 6023G is listed as Active. But, when I tried to schedule a repair for the active recall, the manufacturing website ONLY listed the "closed" recall (3219D) was listed as available for repair, which is bizarre. Please see the attached screenshot of the website. Thanks.
Brakes
Reports naming service brakes, the antilock braking system, brake hoses, master cylinders or the parking brake.
From owner reports, verbatim
The contact owns a 2016 Mazda Mazda3. The contact stated while the vehicle was parked, the parking brake became firm and failed to engage as needed, causing the rear passenger’s side brake pads to not respond as needed after the vehicle was repaired under NHTSA Campaign Number: 17V393000 (PARKING BRAKE). The contact stated that the recall repair failed to fix the vehicle. There was no warning light illuminated. The contact checked the temperature of the brakes and noticed that the brakes were hotter than normal. A dealer was contacted. The vehicle was towed to the dealer where it was diagnosed that the parking brake actuator was rusted on the inside. The vehicle was not repaired. The manufacturer was notified of the failure and opened a case. The failure mileage was 188,900.
Parking brake does not fully disengage. This causes the rear brakes to wear prematurely and also has the potential to generate excessive heat.
Driver assistance
Reports naming forward-collision avoidance, lane keeping, back-over prevention, cruise control and related electronic driver-assistance systems.
From owner reports, verbatim
My 2016 Mazda 3 has had a faulty rearview camera, computerized controls, and monitor display screen for over 2 years now. I am not sure if there is a problem with the electrical system because I have lost the ability to turn on the navigation function, the stereo function, and to see the vehicle maintenance information with non-functioning electrical controls and display screen. Sometimes the monitor display would show a blank screen or a fuzzy screen which is a safety hazard especially when I'm driving my vehicle in reverse and could potentially cause an accident. There has been a recall on the rearview camera since July 2023. I have contacted the Mazda dealership multiple times, and they have repeatedly said that the rearview camera parts are still not available. This is unacceptable because it seriously compromises my safety and the safety of others if I cannot safely back up my vehicle when driving due to the faulty rearview camera, computerized controls and monitor display screen. There should also be a recall on the computerized controls and monitor display screen.
The contact owns a 2016 Mazda Mazda3. The contact received notification of NHTSA Campaign Number: 23V487000 (Back Over Prevention); however, the part to do the recall repair was not yet available. The contact stated that the rearview camera image was distorted or failed to display an image while reversing. The local dealer was contacted. The vehicle was not diagnosed or repaired. The contact stated that the manufacturer had exceeded a reasonable amount of time for the recall repair. The manufacturer was made aware of the failure. The failure mileage was approximately 60,000. Parts distribution disconnect.
Powertrain (other)
Powertrain reports that are not specifically the engine or transmission — driveshafts, axles, transfer cases and differentials.
From owner reports, verbatim
I am writing to formally report a serious safety issue with my 2016 Mazda 3 manual transmission, which experienced a sudden and complete clutch failure at less 60,000 miles — without any warning lights or diagnostic alerts. I am deeply concerned that: •There was no dashboard warning, even as the clutch system failed •The gear indicator was inaccurate in prior days, which may have been an early sign of failure •There was no protection mechanism to prevent complete drivetrain failure during normal use.
Timing cover leak, all maintenance was completed before the service bulletin. This is a TSB but should be a recall for how common this issue is as they stated it could be caused from the assembly line during a pressurized test. “ This may be caused by oil escaping from a fine clearance created at the sealant applied to joint (A)between the cylinder block (B) and head (C) when the engine was pressurized during leak testing on the engine assembly line.” TSB Bulletin No.: 01-018/18. Timing cover issues are not something that should be happening under 100k miles.
Visibility
Reports naming windshields, glass, wipers, defrosters and mirrors.
From owner reports, verbatim
It’s been over a year since recall number 23v-487 was issued Need to get it taken care of
The windshield wipers work but the washer does not squirt the windshield washing fluid out and it the reservoir is full of fluid but there are certain days in which I need that to work because my visibility is greatly reduced which has made the risk of accident that much greater. it says there is a recall pertaining to this problem and the fix was a relay However nothing comes up for my specific car when I enter the Vin but I would like this problem fixed and I’m not sure how to go about it

Airbags
Reports naming the air-bag system — deployment behaviour, inflators, sensors and warning lights.
From owner reports, verbatim
The contact owns a 2016 Mazda Mazda3. The contact stated while driving 40 MPH, the front driver's side door air bag and the front driver's seat air bag deployed. The contact sustained some busies due to the failure. The vehicle was taken to the dealer for inspection and diagnostic testing. The dealer inspected the vehicle and determined the failure was the result of an accident. The contact stated that the vehicle was inspected by Progressive Insurance and noted the failure as a mechanical failure by the manufacturer. The vehicle was not repaired. The manufacturer was made aware of the failure but did not assist. The failure mileage was approximately 126,000.
Nothing has happened yet but Ive done a bunch of research and a lot of the 3rd generation Mazda 3's all have the same airbag code 16 flashing on their dash and it's not on any recall list

Fuel system
Reports naming fuel storage or delivery — tanks, pumps, lines, injectors and fuel leaks.
From owner reports, verbatim
Fuel Tank has corrosion that allows vapors to enter the passenger compartment.
Recently noticed the odor of unburned gasoline, both inside and outside the vehicle. When driving, the ventilation system would flush this away in a few moments, but this phenomenon is new within the past few weeks. Our mechanic (not the dealer) traced the issue to the fuel tank, where the port for the fuel pump and sensors is located on top. This area is accessible by removing the rear seat cushion and a cover plate. He showed me how the fuel pump and sensor module has rusted to the thread of the port, preventing removal of the assembly, and that the port flange itself has rusted and has pin-holes, allowing vapor to escape. He was able to put slight positive air pressure to the tank as a test, and was able to cause liquid fuel to escape from the holes. The tank was about 3/4 full at the time. This seems like a serious safety issue. The port and matching threaded parts (fuel pump / sensor module) that inserts there should be corrosion-proof. I can provide a photo of the affected area if needed; I would get the image file from my mechanic.

Interior & seats
Reports naming seats, latches, locks, linkages and interior fittings.
From owner reports, verbatim
The cup holder on the car seat is damaged, as it broke from the car seat at the time of the incident. The hook in which buckles the car seat to the car is stuck and no longer pulls out nor in, No longer able to tie the car seat into the car correctly. My child is put at risk due to the buckle not being able to tighten nor more. Yes the insurance first stated they would replace it.

From owner reports, verbatim
UNKOWN
I PARKED AT THE TOP OF MY DRIVEWAY AT A SLIGHT INCLINE POSITION WITH THE EMERGENCY BRAKE ENGAGED AND THE CAR WAS IN SECOND GEAR (MANUAL TRANSMISSION). IT WAS IN A STATIONARY POSITION AT THAT TIME. MY FAMILY EXITED THE VEHICLE AND WE WENT INSIDE OUR HOME. APPROXIMATELY A HALF OUR LATER I NOTICE MY CAR ROLLED DOWN MY DRIVEWAY AND CRASHED IN BETWEEN TWO TREES ON MY PROPERTY. EITHER THE EMERGENCY BRAKE FAILED OR THE CAR'S TRANSMISSION FAILED WHILE PARKED. THE CAR WAS FOUND AT THE BOTTOM OF MY PROPERTY STILL IN GEAR AND HAD THE EMERGENCY BRAKE IN THE ENGAGED POSITION.

From owner reports, verbatim
The contact owns a 2016 Mazda Mazda3.The contact stated that while driving at various speeds, the contact stated that the vehicle's steering wheel would fail to operate as needed. The contact stated that an abnormal, clunking noise would emit from the steering wheel while turning at various speeds. The contact also stated that the steering wheel felt loose while driving at high speeds, fearing that he would lose control of the vehicle if he did not firmly grip the steering wheel.

THIS CAR IS TOO NEW TO HAVE THIS PROBLEM. MAZDA WILL NOT EVEN TRY TO HELP ME. THIS CAR IS MY LIFELINE.

Other / unspecified
Reports whose component NHTSA recorded as unknown, or that do not map to one of the categories above.
From owner reports, verbatim
The cup holder on the car seat is damaged, as it broke from the car seat at the time of the incident. The hook in which buckles the car seat to the car is stuck and no longer pulls out nor in, No longer able to tie the car seat into the car correctly. My child is put at risk due to the buckle not being able to tighten nor more. Yes the insurance first stated they would replace it.
When cleaning and adjusting the seat to move it to forward-facing, we discovered that two of the child harness straps (the crotch strap and one of the shoulder straps) had significant grooves cut into them, presumably by the plastic edges of the base. Given that this damage was not visible before moving the cover and adjusting the seat, and given that Graco advertises this seat as rear-facing from 4 to 50 pounds and forward-facing up to 65 pounds, a consumer wouldn't see or have any reason to expect this level of damage after about 3.5 years of use. I have to assume that this sort of severe wear compromises the strength of the straps and thus the safety of the seat if there were an accident (thank goodness we didn't have one). I have the seat still, and I contacted the manufacturer with pictures of the damage, and they did not seem to think it was out of the ordinary or alarming at all, just told me that they could send me a rebate for a discount on a new seat if I wanted since this one was out of warranty. I cannot believe that this is an acceptable and safe amount of normal wear. I can attest that we followed manufacturer instructions for care and install and did not use any cleaning products on the seat, submerge the seat, leave it outside, or do anything else that I can think of that would have constituted inappropriate care of the seat.

Seat belts
Reports naming seat belts, buckles, retractors and pretensioners.
From owner reports, verbatim
The contact owns a 2016 Mazda Mazda3. The contact stated that while the vehicle was parked, the driver’s side seat belt became inoperable. The contact stated that the seat belt latch failed to function properly. The vehicle was taken to the dealer but was not diagnosed or repaired. The manufacturer was made aware of the failure. The failure mileage was approximately 60,000.
Apparently all of sudden the front occupants seat belt had lock and malfunctioning to the point you are unable to pull the belt strap to securely wrapped around the passenger, took it to have it evaluated at the request of the auto maker, supposedly this what I understood from two separate auto repair shops ( Mazda) dealership and a reliable auto repair (Apex) shop stating that a spring loaded system mechanism part was actually missing and that the standard mechanical labor (code) cost for the repair were not (unknown) listed while the other suggested the whole seat belt needed to be replaced I strongly feel this should be a safety related issue for both the driver and passenger seat belts should be recalled and carefully looked into for driver/passenger safety reasons.
