Overview

Mazda's light crossover, built on the DJ Mazda2 platform and sold in Australia from early 2015 across Neo, Maxx, sTouring, Maxx Sport, Akari and special editions. It is a monocoque on-road soft-roader - low ground clearance, mostly front-wheel drive, with optional on-demand i-ACTIV AWD on the higher grades and the diesel. Mechanically it is a smart used buy because it avoids the dual-clutch and CVT gremlins that plague rivals: every CX-3 uses a conventional torque-converter 6-speed auto (or a 6-speed manual on early cars), and the petrol is a timing-chain naturally aspirated SkyActiv-G. The volume engine in Australia is the 2.0L SkyActiv-G (PE-VPS, 110kW/195Nm); a 1.5L SkyActiv-D twin-cam turbo-diesel (S5-DPTS, 77kW/270Nm) was offered from 2015 but sold poorly and was quietly dropped around 2018, so diesels are rare and need extra scrutiny. The diesel is the one to be cautious about - it was subject to a serious 'engine over-run / self-destruct' recall and shares the SkyActiv-D family's DPF, intake-coking and oil-dilution tendencies on short city trips. Across the range the well-known issues are minor: a large reversing-camera wiring recall, a fuel-pump impeller recall on 2017-2019 builds, an engine over-run PCM recall, MZD Connect infotainment glitches, thin/easily-chipped paint, a tight rear seat and small boot, and Takata airbag recalls on early cars. Note the 2.0 was lightly revised over the years (later cars are quoted around 109kW/192Nm with cylinder-deactivation on some) - don't read minor spec differences as different engines.

Transmission

Timing chain / belt / gear

Timing chain (no scheduled belt replacement)

Pros

Simple, tough naturally aspirated petrol - no DPF, no turbo
Timing chain, no belt to replace
Conventional 6-speed torque-converter auto (or 6MT), not a CVT or DCT - a real reliability advantage over rivals
Cheap to buy and run with an excellent reliability record; FWD or i-ACTIV AWD available

Cons

Only modest 110kW/195Nm - feels stretched fully loaded or on hills
Low 1200kg braked tow rating
Direct-injection intake-valve carbon possible at high km
Subject to the engine over-run / fuel-pump impeller recalls - check they were done

Known problems

high

Engine over-run / uncontrolled high-RPM (oil-draw) recall

If the engine is revved hard in Park/Neutral, residual oil accumulating in the intake can be drawn in, causing the engine to run away at high RPM until it is damaged or destroyed. The subject of an Australian recall requiring a revised PCM calibration.

Fix: Confirm the PCM recalibration recall was completed via VIN; have it done free at a Mazda dealer if outstanding.

Any (affected build years) · Recall (free) to $3000+ if ignored

medium

Fuel-pump impeller failure (2017-2019 recall)

A defective low-pressure fuel-pump impeller can crack and swell, causing rough running, stalling or a no-start. Part of a large Mazda recall covering ~90,000 Australian vehicles including the CX-3.

Fix: Check the fuel-pump recall is complete; replace the in-tank pump if symptomatic and not covered.

Any (2017-2019 builds) · Recall (free) to $600-1200

low

Direct-injection intake-valve carbon

Like most direct-injection petrols the SkyActiv-G can build carbon on the intake valves over time (no port-injection wash), causing rough idle or minor misfire at high km.

Fix: Walnut-blast / intake clean if symptomatic; quality fuel and regular oil changes slow it.

Excellent economy (mid-4s to low-5s L/100km) and strong low-down 270Nm torque
Timing chain and a conventional 6-speed auto/manual - no DCT or CVT
Refined and quiet for a small diesel; long touring range
FWD or i-ACTIV AWD available

Cons

Subject of a serious engine over-run / 'self-destruct' recall - verify it was rectified
DPF / EGR / intake coking and oil-dilution on short urban trips, like all SkyActiv-D
Sold in tiny numbers and dropped around 2018 - parts and diesel expertise scarce
A poor fit for short-trip city use; only worth it for regular highway running

Known problems

high

Engine over-run / 'self-destruct' recall (diesel)

Australian CX-3 diesels were recalled because residual oil in the intake could be drawn into the engine, causing uncontrolled high-RPM run-away until the engine failed - widely reported as the 'self-destructing engine' recall.

Fix: Confirm the recall (PCM/intake rectification) was completed via VIN before purchase; have any outstanding recall done at a Mazda dealer.

Any (affected build years) · Recall (free) to engine replacement if ignored

high

DPF clogging, EGR and intake/swirl-valve carbon coking

Short urban trips stop the DPF completing regeneration, leading to blockages, forced regens and heavy soot coking of the EGR, intake and swirl valves - causing rough running, lost power and limp mode, a signature SkyActiv-D problem.

Fix: Regular 20-30 min highway runs to allow regen; clean EGR/intake; budget for a DPF on a neglected town car.

Any (worse on short trips) · ~$800-3000 (new DPF $1500+)

medium

Oil dilution / rising oil level (DPF regen)

Post-injection during DPF regen washes diesel past the rings into the sump; on short trips the regen never completes, oil level rises and thins, accelerating wear. Common to the SkyActiv-D family on city-only use.

Fix: Do regular highway runs; change oil early and monitor the level; avoid for short-trip-only duty.

Any (worse on short trips) · ~$300-2500

Common problems (all variants)

medium

Reversing-camera wiring recall

A very large Australian recall (over 176,000 Mazda vehicles including the CX-3) covered a wiring problem that could disable or disrupt the reversing-camera display - a reversing-safety concern.

Fix: Confirm the reversing-camera wiring recall has been completed via VIN; have it rectified free if outstanding.

Any (2015-2020 builds) · Recall (free) to $200-600

medium

Front suspension joint / fastener recall

The DK CX-3 was subject to a recall involving a front suspension joint/fastener that could loosen or fail, potentially affecting handling.

Fix: Run the VIN through Mazda / Product Safety recall checks and confirm the suspension recall was completed.

Any (affected builds) · Recall (free)

high

Takata airbag recall (early cars)

Like most cars of the era, early CX-3s were caught in the industry-wide Takata airbag inflator recall, where ageing inflators can rupture and fire shrapnel.

Fix: Verify the Takata airbag recall has been completed; do not drive an affected unrectified car - rectification is free.

Any (early DK) · Recall (free)

low

MZD Connect infotainment glitches

The MZD Connect head unit can freeze, reboot, drop Bluetooth, fail to connect Android Auto / Apple CarPlay, or show a faded/mottled screen; some units need replacement.

Fix: Software/firmware update first; replace the display or head unit if hardware-faulty.

Any · ~$0-1200

low

Thin paint / dark-colour chipping

Paint is thin and chips easily, particularly on dark colours and the popular Soul Red; stone chips on the bonnet and front bumper are common.

Fix: Paint protection film up front; touch-up or respray affected panels.

Any · ~$200-1500

low

Tight rear seat / small boot and headlight condensation

Practical niggles rather than faults: a cramped rear seat and small boot for the class, plus reports of headlight condensation appearing after the warranty period.

Fix: Headlight condensation can sometimes be cleared by reseating/drying the unit or replacing the seal; the packaging limits are inherent to the car.
