Reliability & federal safety record

Owner-reported issues, recalls, investigations and service bulletins on record with NHTSA — an unfiltered look at what owners actually experience.

Owner complaints about the 2017 Mazda CX3 lead in one area — the fuel/propulsion system, 6 of 21 reports (29%), well ahead of the next concern. None of this vehicle's 1 recall campaigns target the fuel/propulsion system, so those reports read as owner-reported wear-and-tear rather than an acknowledged defect. 2 of the reports describe a crash and 0 a fire — a small share of the total, but worth weighing against the fuel/propulsion system pattern above. These are tallies of what owners actually reported to the federal government, not an editorial score — and higher-selling models naturally rack up more reports.
