PRODUCTION-ADJUSTED DESCRIPTIVE METRIC

NORMALIZED COMPLAINT CONTEXT

Production-normalized complaint data is not currently available for this vehicle.

This metric compares the number of NHTSA owner complaint records retrieved by CarIQ with NHTSA-reported production volume for the corresponding vehicle population.

It is not a vehicle failure rate. Complaint reporting behavior, vehicle age, time on the road, production definitions, and other factors can affect the result.

RECENT OWNER COMPLAINTS

Fuel/propulsion System

Owner-submitted NHTSA complaint · ODI 11748076
Read complaint narrative

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.

Power Train

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.

Suspension

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.

NHTSA complaints are reports submitted by vehicle owners and other consumers. Complaint counts do not represent the percentage of vehicles affected and do not by themselves establish that a safety defect exists.

A higher complaint count can partly reflect how many vehicles were sold, vehicle age, and other factors. CarIQ does not yet normalize complaint counts by vehicles sold.

OFFICIAL NHTSA MANUFACTURER COMMUNICATION DATA

MANUFACTURER COMMUNICATIONS

TOTAL COMMUNICATIONS0

No NHTSA manufacturer communication records were returned for this year, make, and model.

Manufacturer communications include service bulletins and other technical information submitted by manufacturers to NHTSA. The existence or number of communications does not establish how often a condition occurs or whether an individual vehicle will experience it.

Some manufacturers may issue more detailed service documentation than others, so communication counts should not be used alone to compare vehicle reliability.

NHTSA DEFECT INVESTIGATIONS

TOTAL INVESTIGATION RECORDS0

No applicable NHTSA defect investigation records were returned for this year, make, and model.

NHTSA investigations evaluate potential motor-vehicle safety defects. The existence of an investigation does not by itself establish that a safety defect exists, and the absence of an investigation does not establish that a vehicle is problem-free.

Open and closed describe NHTSA's process status, not a CarIQ reliability judgment.
