DJ3FS/DJ5FS/DJLFS (2014+) · 2014–present
1.3 Skyactiv-G (to Aug 2018) · 92 hp · 1.5 Skyactiv-D · 105 hp · 1.5 Skyactiv-G 110 PS (Aug 2018+, regular petrol) · 110 hp · 1.5 Skyactiv-G 116 PS (15MB, premium petrol, from 2015) · 116 hp
Known problems
- Critical usually from 0 mi (0 km)
Petrol low-pressure fuel pump impeller may swell and stall the engine
Symptoms: hard starting although the starter spins normally, loss of power while driving, rough running, in the worst case the engine stalls on the move
What to do: Applies to 1.3 and 1.5 petrol Demio/Mazda2 built 2017-2019 (two notifications). The pump is replaced free once parts are available; owners were mailed in 2024. Check the VIN on Mazda's recall search; if hesitation or a long crank appears, stop in a safe place and call a dealer.
- Critical usually from 0 mi (0 km)
SKYACTIV-D 1.5: soot builds up on injectors and exhaust valves
Symptoms: engine warning light or glow-plug light flashing, weak acceleration, vibration; in the worst case the engine stops
What to do: Two linked recalls (2016 and the 2018 follow-up), covering the 2014-2017 diesels. The software is updated, soot is cleaned from injectors, valves and the DPF, and valve springs and injectors are replaced free if the warning appears. Check the VIN; if the engine light or flashing glow lamp shows, go to a dealer promptly. Avoid a life made only of slow stop-and-go trips.
- Critical usually from 0 mi (0 km)
i-ELOOP diesel: DC-DC converter fault can short-circuit and burn
Symptoms: i-ELOOP warning light with a flashing i-stop light, then possible flat battery and engine stop; in the worst case a fire
What to do: Applies only to diesel cars with i-ELOOP deceleration energy recovery, built to April 2017. The engine computer is checked and reprogrammed, and the converter is replaced if faulty. If the i-ELOOP lamp comes on, do not keep driving; contact a dealer.
- Worth watching
1.5 petrol: S-VT actuator can fail (2018-2019 builds)
Symptoms: engine warning light and reduced power with poor acceleration
What to do: A software correction, with an actuator swap if a specific fault code is stored. Ask a dealer whether a 2018-2019 car with the 1.5 petrol engine was covered.
- Worth watching
A/C condenser tube corrosion (2014-2016 builds)
Symptoms: air conditioning blows warm because refrigerant leaks from a corroded condenser; road-salt and snow-melt exposure speeds it up
What to do: Car-by-car, based on the condenser part number; the condenser is replaced free if affected. If the A/C loses cooling in a snowy-region car, say so at the workshop.
- Worth watching usually from 0 mi (0 km)
Diesel accessory drive belt may snap (2014-2015 builds)
Symptoms: warning lights from a stopped alternator or water pump; in the worst case the engine stops and will not restart
What to do: Early diesel builds only. The belt is replaced free after a VIN check; today most surviving cars should have had it done, but a car from before late 2015 that never visited a dealer may be open.
- Worth watching
Diesel alternator pulley grease degrades (warranty extended to 10 years)
Symptoms: noise from the alternator pulley, then a charging-system warning light
What to do: For 2014-2019 diesel Demios Mazda extended the warranty on this fault to 10 years from registration with no mileage limit. If the alternator squeals or the charge lamp lights, ask a dealer to inspect; they swap the alternator and belt free if it qualifies.
- Worth watching usually from 0 mi (0 km)
Diesel fuel filter drain plug can leak
Symptoms: diesel smell or wet fuel filter after a service in which the drain plug was loosened and retightened
What to do: Two overlapping campaigns (2015 and 2016) on diesel cars built 2014-2016: an interim filter swap, then replacement of the drain plug and gasket. Check the VIN, and look for fuel wetness around the filter on an old diesel.
- Worth watching
SKYACTIV-D DPF clogs on short trips; fuel in the oil is expected
Symptoms: DPF lamp lights; the oil level rises slightly; engine note or exhaust smell changes while the filter cleans itself
What to do: Mazda says the filter cannot burn off soot when you crawl below about 15 km/h, repeat trips of 10 minutes or less, or idle for long. When the DPF lamp comes on, drive about 15-20 minutes above 20 km/h with a fully warm engine; a flashing lamp means go to a dealer. Use only the specified diesel oil (wrong oil ages the DPF faster) and keep to the severe-use oil interval for short-trip use.
- Good to know
Cars with i-stop need an idle-stop rated battery
Symptoms: i-stop stops working or takes long to engage after a weak or wrong battery, or after the terminals were disconnected
What to do: Fit a battery of the idle-stop class (Q-85 for the petrol and i-ELOOP diesel, S-95 for the diesel without i-ELOOP) and have the i-stop function checked after a change; Mazda recommends its own batteries.
Service schedule
| Item | Interval | Notes |
|---|---|---|
| Engine oil & filter change (Skyactiv-D diesel) Important | every 6,000 mi (10,000 km) or 12 months | Whichever comes first; 5,000 km or 6 months under severe conditions, e.g. short trips. Same Mazda manual page. Use only the listed diesel oils: other oil ages the DPF faster. |
| Engine oil & filter change (petrol) | every 9,000 mi (15,000 km) or 12 months | Whichever comes first; 7,500 km or 6 months under severe conditions. Mazda Japan owner's manual, DJ Demio (www2.mazda.co.jp/carlife/owner/manual/demio/dj/edke/contents/07051200.html, read 2026-10-26). Oil: genuine Golden ECO 0W-20 recommended; reset the oil data after each change. |
| Fuel filter water drain (Skyactiv-D) Important | every 12,000 mi (20,000 km) | Same Mazda manual page; skipping the drain can damage the engine, per the manual. Have a dealer do it. |
| Fuel filter replacement (Skyactiv-D) Important | every 37,000 mi (60,000 km) | Mazda manual, www2.mazda.co.jp/carlife/owner/manual/demio/dj/edke/contents/07051500.html (read 2026-10-26). |
| Coolant | every 62,000 mi (100,000 km) or 48 months | Golden long-life coolant: 100,000 km or 4 years; the first change at 180,000 km or 9 years. Standard long-life coolant: 2 years, first at 3 years (Mazda manual, www2.mazda.co.jp/carlife/owner/manual/demio/dj/edke/contents/07050200.html, read 2026-10-26). |
| Brake fluid Important | every 24 months | Every 2 years, first change at 3 years (Mazda manual, www2.mazda.co.jp/carlife/owner/manual/demio/dj/edke/contents/07050300.html, read 2026-10-26). DOT 3. |

DE3FS/DE3AS/DE5FS/DEJFS (2007-2014) · 2007–2014
1.3 Skyactiv-G (13-SKYACTIV, i-stop, 2011+) · 84 hp · 1.3 ZJ-VE · 91 hp · 1.3 ZJ-VEM (mirror-cycle, 13C-V with CVT) · 90 hp · 1.5 ZY-VE · 113 hp
Known problems
- Critical usually from 0 mi (0 km)
Driver seat height lifter link may crack (manual height adjuster)
Symptoms: creaks or play from the driver's seat; in the worst case the lifter link breaks or comes off and the seat tilts so the driver can no longer hold a proper driving position
What to do: Applies only to cars with the manual seat-height lever, built to September 2010. A dealer inspects the link and fits a reinforcing bracket, or replaces the seat adjuster if cracked. If the seat rocks or clunks, have it checked even if the VIN was cleared.
- Critical usually from 0 mi (0 km)
Front strut lower bolts may loosen (US Mazda2 2013-2014)
Symptoms: loosening of the nuts and bolts that join the front strut to the steering knuckle; in the worst case the knuckle separates from the strut and steering control is lost
What to do: US-market cars only (2013-2014 Mazda2 built July 2013 to August 2014); no matching Japanese Demio campaign was found. A Mazda dealer checks the bolts and retightens or replaces them free of charge.
- Critical usually from 0 mi (0 km)
Passenger airbag inflator (Takata) replacement
Symptoms: no visible symptom; the propellant in the front-passenger inflator can degrade after long exposure to humidity and temperature swings, so the inflator housing could rupture and throw fragments in a deployment
What to do: Very large campaign covering most 2007-2014 Demio. Check the VIN on Mazda's recall search or with a dealer; the inflator is replaced free. In Japan a car with the Takata repair outstanding is refused at the shaken inspection, so an old car that has never been in a dealer may still be open.
- Worth watching
Rear hub bearing can rust after slush-road driving (early 2WD builds)
Symptoms: humming or growling noise from a rear wheel in cars that are driven through melting snow; water collects in the rear hub and rusts the bearing surface
What to do: Small early-build batch (built to January 2008, 2WD). Dealers sealed the axle and, in snowy regions, checked the hub for rust. If a rear wheel hums, have the hub bearing checked and ask whether the sealant fix was done.
- Good to know
Early 13-SKYACTIV (i-stop) cars: software campaigns for restart, throttle timing and steering assist
Symptoms: engine may not restart on its own after an i-stop pause (the key still starts it); the intake variable valve timing can stick, with the engine warning light and weak acceleration; on some 2012-2013 cars the power steering may stay unassisted after an automatic restart
What to do: All three were software or part fixes done years ago on request; ask a dealer whether the VIN is covered. If an i-stop car behaves oddly after a restart or the engine light comes on, mention these campaigns when asking for diagnosis.
Service schedule
| Item | Interval | Notes |
|---|---|---|
| Engine oil & filter change | every 9,000 mi (15,000 km) or 12 months | Whichever comes first; 7,500 km or 6 months under severe use. From Mazda's Japanese owner's-manual page for a 'DEMIO' first edition (document 70201, API SM / 0W-20 oil). The page names neither the generation nor the engine, so confirm in your own booklet. The Skyactiv-G 1.3 (13-SKYACTIV) is not listed on that page. |
| Brake fluid Important | every 24 months | Conventional fallback, not a manufacturer figure for this generation (the later DJ manual gives 2 years, first change at 3 years). |
| Spark plugs, air filter, cabin filter, coolant | — | No interval stated on any Mazda page opened for this generation. Follow the maintenance booklet (メンテナンスノート). |
