Low pressure fuel pump failure with 75,575 miles on odometer. Fuel pump completely seized. Car was parked at a retail location and would not start. Upon troubleshooting, mechanic was able to determine the low pressure pump was not delivering fuel. Pump was replaced. Faulty fuel pumps could lead to hazardous conditions as they are mounted within the fuel tank. I feel this is too early in the vehicles life for this component to have completely failed.

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 NHTSA investigate to determine if additional vehicles are impacted by Mazda's faulty torque converters.

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.

Google search shows Mazda has common problem with their front sensing camera, people are reporting the issue for different Mazda models across the board for the last few years including newer models as well. 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. Automatic switching between high and low beams is unavailable.
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.
