2020 Mazda Mazda3

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.
