Faults that affect 2019 cars
- Medium severityFrequency: OccasionalFuelMicro-cracks in the fuel pump impellerBetween October 2017 and May 2020, Mazda built Mazda3 and CX-5 units with a fuel pump whose impeller can crack, swell and end up cutting off the fuel supply with the engine running; the manufacturer recalled the affected cars.
- Medium severityFrequency: OccasionalElectronicsECU programming and loss of power (CX-5 II and Mazda3 IV)On the CX-5 II built between 2017 and 2019, and the 2019 Mazda3 IV, incorrect engine ECU programming can cause loss of power or the engine to stall; Mazda fixes it with a software update acknowledged by Germany's KBA.
- Low severityFrequency: CommonIntakeCarbon build-up in the intake manifold and injectorsLike almost any direct-injection petrol engine, the Skyactiv-G accumulates carbon on the intake valves over the miles and can foul the injectors, with loss of power and a rough idle; gebrauchtwagenberater.de documents it on the Mazda2, Mazda3, CX-3, CX-30 and CX-5.
- Low severityFrequency: OccasionalLubricationHigher-than-normal oil consumptionSome Mazda3 BM/BN with the Skyactiv-G engine use more oil than expected between changes; the manufacturer itself considers up to 0.8 litres per 1,000 km normal, but gebrauchtwagenberater.de recommends not ignoring higher figures and checking the level regularly.
