# Mazda Mazda3 2014–2018 · Pre-purchase checklist

Bring this to the inspection. Every check below is specific to this generation's documented failure modes, not generic used-car advice.

Check 01

Run the VIN for open recalls, especially 17V-393 (rear parking-brake actuator corrosion, 2014–2016) and, on a 2018, the low-pressure fuel pump recall. A Mazda dealer or NHTSA.gov does this free.

Check 02

Feel for brake drag: after a test drive, carefully check whether either rear wheel is hotter than the other. A seizing rear caliper is this car's signature failure.

Check 03

Work Mazda Connect hard for the whole test drive: watch for reboots, freezes, a black screen, or ghost inputs. A flaky CMU is a four-figure dealer fix.

Check 04

On manuals: full-throttle pull in 3rd–4th gear and watch for clutch slip; a high, vague engagement point on a low-mile car is the known pressure-plate failure starting.

Check 05

Listen for a speed-dependent hum at 40+ mph that changes when you swerve gently. Front and rear wheel-bearing hubs are a common wear item on 2014–2015 cars.

Check 06

Check brake pad and rotor life at all four corners. These cars eat rear brakes faster than most compacts, and prior owners often deferred it.

Check 07

Confirm the automatic's fluid has been serviced at least once by 75k–100k miles; skipped fluid is the main thing that kills the otherwise-solid 6-speed.

Walk-away signals

2014 (first-year car, most complaints by far: brakes, infotainment, interior quality) · 2014–2016 manuals unless the clutch has been replaced or passes a hard test drive
