107NHTSA owner complaints
4safety recalls
$1,200worst-case single repair
The best-driving compact car of its generation, undone slightly by a fussy infotainment screen and a couple of dumb recalls.
Every documented failure, earliest first
Ordered by the mileage the problem typically appears. VERY HIGH
confidence means it's tied to a documented NHTSA recall, and 1 of these are rated Critical.
0k–15k mi● Critical$0–$300VERY HIGH
Windshield wiper relay failure (recalled) — wipers stop working mid-drive
How to catch it: Confirm the wiper relay recall (part of the 4 listed) was actually performed — check VIN on NHTSA's recall lookup before buying.
Source: documented (NHTSA recall)
20k–50k mi● Plan$500–$1,200MODERATE
Mazda Connect infotainment screen cracking / 'ghost touch' malfunctioning
How to catch it: Ask Mazda dealer if the Special Service Program was extended to your VIN before paying out of pocket — it originally covered 2014-2016 cars only, so push back if yours does it too.

30k–60k mi● Watch$0–$400VERY HIGH
Rear-view camera image distortion/no-display (recalled harness/connector issue)
How to catch it: Verify recall completion; if camera flickers or shows static, get the wiring harness inspected under warranty first.
Source: documented (NHTSA recall)
40k–70k mi● Watch$300–$600MODERATE
Front brake rotor warping / squeal (soft OEM pads and rotors)
How to catch it: Upgrade to slotted rotors and better pads at first replacement — OEM parts warp early under spirited driving.

60k–90k mi● Watch$400–$900MODERATE
Skyactiv-G 2.5L timing chain tensioner noise (rare but reported rattle on cold start)
How to catch it: Use full-synthetic oil on schedule and listen for cold-start rattle; catch tensioner wear before it stretches the chain.

80k–120k mi● Plan$800–$1,200MODERATE
Clutch wear on manual transmission cars (light clutch, easy to abuse)
How to catch it: Budget a clutch job around 100k if it's been driven hard — the light pedal feel invites slipping habits.
