The 2020MAZDAMAZDA3 carries 49 consumer safety complaints in NHTSA's Office of Defects Investigation database for this specific model-year cohort. Within that volume, owners reported 0 crashes, 0 fires, 0 injuries, and 0 fatalities. For crash performance, NHTSA's New Car Assessment Program gave this cohort an overall 5/5 rating, with 5/5 front crash, 5/5 side crash, and 5/5 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 2020 MAZDA3 is forward collision avoidance: automatic emergency braking with 13 filings, followed by forward collision avoidance: warnings (9) and steering (3). 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 2 active recall campaigns, 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 2020 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.

FORWARD COLLISION AVOIDANCE: AUTOMATIC EMERGENCY BRAKING
Mazda North American Operations (Mazda) is recalling certain 2019-2020 Mazda3 vehicles. The Smart Brake System (SBS) can falsely detect an obstacle while driving, activating the automatic emergency braking system and suddenly stopping the vehicle.

Mazda North American Operations (Mazda) is recalling certain 2020 CX-30 and Mazda3 vehicles. The front brake caliper mounting bolts may not have been tightened properly during assembly, possibly allowing the calipers to loosen.
My Mazda3 began producing a chirp when shifting from 3rd to 4th gear (automatic transmission). The dealer stated that the car needed a new torque converter. At the time the car only 37,000 miles on it, quite low mileage for a torque converter to fail. Mazda has previously admitted to producing cars with faulty torque converters, as specified in Mazda TXXXXXX] ). While my car fit the description of both the problem and proposed fix, and also fell within the applicable models/VINs listed on the TSB, Mazda corporate HQ stated that my specific VIN was not covered by the TSB, and therefore the repair cost was my responsibility. Since the problem, solution, and general vehicle type are entirely as described in the TSB, it appears possible that the TSB was too narrowly scoped and omitted impacted vehicles, to the detriment of owners. This would also cause potential safety concerns, since an unrepaired torque converter could produce unexpected shifting problems. Therefore I suggest that NHT
I pulled into the driveway (at about 5 mph) of my passenger's home, when a very loud, metallic pop occurred somewhere inside my vehicle. I could not discern the problem by visually inspecting the car. Upon returning to my home, I arranged for the dealership to inspect the car's suspension. They found that both rear springs had snapped off from their lower vehicle attachment points. At the time of the incident, my car was less than 6 years old and had approximately 62500 total miles. I had the dealership replace both rear springs and associated attachment hardware. Prior to this failure, the dealership had routinely inspected the suspension of my vehicle as part of PA annual inspections. I experienced NO warning symptoms prior to the suspension failure.

My car display shows few malfunction warning messages. Following captured from MyMazda app. 1. Forward sensing camera malfunction. i-ACTIVESENSE advanced safety and driver support systems may not operate correctly. 2. High Beam Control System is disabled.

While driving on a residential street the automatic emergency braking system activated and brought the car to a very abrupt stop but there was nothing in the front of the car to activate the system. There were no cars in the on-coming lane and no cars in the lane beside my car. When the car stopped the Brake warning appeared in the windshield and a warning tone sounded. It was in the early evening and it was raining. Fortunately there were no cars behind me so there were no injuries. I took the car to the Mazda dealership and upon inspection they noted that the radar system associated with the automatic emergency braking system was malfunctioning and not correctly calculating the distance between the car and other objects. They are in the process of replacing the radar. If this had happened on the highway at higher speeds or if there had been a car behind me I would have been injured.
My car's automatic emergency brake is deploying without warning, during driving, when there are no other cars in my forward proximity. I took it to the dealership to have it fixed, and on the drive home, it did it again. There is a recall for similar makes and models for this year, but my car has not been included.

on 3 occasions may 2023, June 2023 and July 2023 the forward Collison camera activated. in May and June it showed the vehicle to near stop like radar cruise control in rush hour speed traffic. in July 2023 it sounded the alarm and came to a full stop in heavy traffic. it occurs on bright hot days going straight no turns no oncoming traffic no traffic around and no obstacles hold or dips. this can cause the car to stop immediately and cause an accident. App detects problem with system but dealer cannot find problem and blame camera or GPS or satellite radio factory equipped.

in May 2023 the visors of the vehicle hinge melted causing the visors to hang down to eye level and would not hold up causing visibly issues for driver and passenger. dealer said it is a common issue in heat but it blocks forward visibility and won't hold up and if there were and accident, forward movement of passenger or driver can cause the head to hit the visor causing injury.

Automatic safety notification censoring system for the brakes engaged when a stop was not applicable or necessary causing the car to brake on its own in traffic. Luckily no one else was on the road.
Lane departure warning activated and attempted to correct during a gentle curve. The location had shifted lanes due to construction, so clear lines were visible but not the actual lane to follow which is a frequent occurrence in New York City. The system came close to steering me into the adjacent lane occupied by another vehicle forcing me to fight the correction. There was a lane departure warning on the dash and I believe the blind spot indicator was on (i.e. the adjacent vehicle was detected in some capacity). I considered this especially dangerous as in this zone also had very tight lanes so my physical correction could have also caused an accident. There was no malfunction of the physical components. No dealer or service center has reproduced the issue however I have discussed with other drivers of the same line (2020-23 Mazdas) who have had similar experiences leading to a decision to disable these "safety" features. Mazda provides a reasonable description of scenarios where la
