Problems & Worst Years

With just 47 complaint occurrences across eight distinct problems, the 2018 Mazda3's NHTSA record is modest compared to many other models in this data set, and none of its reported issues carry a safety-severity rating. The most common complaint is an infotainment glitch owners describe as ghost touch — the touchscreen registering inputs on its own — logged 17 times at high severity, more than a third of all reports for the year. A malfunctioning backup camera follows at 10 occurrences, also rated high.

Mechanically, the picture is thinner but not absent: five owners reported the engine stalling during an attempted start, five reported windshield wiper system failures, and four described a high-pressure fuel pump failure rated high severity. None of these approach the volume of the infotainment complaint, but a fuel pump issue paired with stalling on startup is worth asking a seller or independent mechanic to check, particularly on a higher-mileage example.

Two NHTSA recall campaigns are on file for this model, 17V745 and 21V875, and a buyer should confirm both have been completed using the vehicle's VIN before purchase — an open recall is a straightforward thing to resolve and shouldn't be a dealbreaker on its own.

Overall, this is a comparatively clean data year for the Mazda3, with low total volume and no safety-rated complaints, though it's the only year of data available here, so there's nothing to compare it against directly. It's worth keeping in mind that these figures reflect owner-filed reports rather than a true failure rate, and that a pre-purchase inspection plus a look at the service history will tell you more about any individual car than the model year alone.
