3rd gen (JF5/JF6) · 2023–present
0.66 (NA) · 58 hp · 0.66 Turbo · 64 hp
Known problems
- Good to know usually from 25,000 mi (40,000 km)
Idling-stop (auto start-stop) battery wear
Symptoms: start-stop dropping out or slow cranking as the dedicated battery ages
What to do: Fit the correct heavy-duty idling-stop battery when needed and expect it to wear sooner than an ordinary battery.
- Good to know usually from 56,000 mi (90,000 km)
CVT longevity (watch item)
Symptoms: possible rubber-band feel or low-speed shudder emerging only at higher mileage as the kei CVT wears
What to do: This generation is recent with little long-term history, so treat CVT smoothness as a watch item: service the fluid periodically, avoid harsh launches, and have any judder checked if it appears.
Service schedule
| Item | Interval | Notes |
|---|---|---|
| Engine oil & filter change | every 6,000 mi (10,000 km) or 12 months | shorten for mostly short-trip city use, and on the turbo |
| Cabin filter | every 9,000 mi (15,000 km) | — |
| Air filter | every 19,000 mi (30,000 km) | — |
| CVT fluid important | every 25,000 mi (40,000 km) | regular changes help the kei CVT last |
| Spark plugs (iridium) | every 62,000 mi (100,000 km) | — |
| Brake fluid important | every 24 months | — |
| Timing chain (no belt) | — | chain-driven — no scheduled belt |
2nd gen (JF3/JF4) · 2017–2023
0.66 (NA) · 58 hp · 0.66 Turbo · 64 hp
Known problems
- Worth watching usually from 56,000 mi (90,000 km)
CVT wear and low-speed shudder at high mileage
Symptoms: rubber-band feel, a shudder or hesitation from a standstill, and gradual loss of smoothness as the kilometres build
What to do: Service the CVT fluid periodically, avoid harsh launches, and have any judder or standstill hesitation diagnosed early — the small kei CVT is worked hard in a heavy tall body.
- Worth watching usually from 62,000 mi (100,000 km)
Turbo wear on the turbocharged engine
Symptoms: loss of boost, turbo whine, or rising oil use on higher-mileage turbo cars
What to do: Use fresh correct-grade oil, let the turbo cool after hard driving, and inspect early if boost drops or oil use rises — the little turbo works hard in a heavy kei.
- Good to know usually from 25,000 mi (40,000 km)
Idling-stop (auto start-stop) battery wear
Symptoms: start-stop stops working, slow cranking or a battery warning as the special battery ages
What to do: Fit the correct heavy-duty idling-stop battery when it fails, not a standard one, and budget for it wearing sooner than an ordinary battery.
Service schedule
| Item | Interval | Notes |
|---|---|---|
| Engine oil & filter change | every 6,000 mi (10,000 km) or 12 months | shorten to ~5000 km for mostly short-trip city use, and on the turbo |
| Cabin filter | every 9,000 mi (15,000 km) | — |
| Air filter | every 19,000 mi (30,000 km) | — |
| CVT fluid important | every 25,000 mi (40,000 km) | regular changes help the kei CVT last in stop-start use |
| Spark plugs (iridium) | every 62,000 mi (100,000 km) | inspect/replace sooner on the turbo |
| Brake fluid important | every 24 months | — |
| Timing chain (no belt) | — | chain-driven — no scheduled belt; investigate any cold-start rattle |
1st gen (JF1/JF2) · 2011–2017
0.66 (NA) · 58 hp · 0.66 Turbo · 64 hp
Known problems
- Worth watching usually from 50,000 mi (80,000 km)
CVT wear and low-speed shudder at high mileage
Symptoms: rubber-band feel under acceleration, a shudder or hesitation pulling away from a standstill, and gradual loss of smoothness as the kilometres climb
What to do: Change the CVT fluid periodically even though the schedule treats it lightly, avoid harsh full-throttle launches with a small kei CVT, and have any judder or hesitation from a standstill checked before it worsens.
- Worth watching usually from 50,000 mi (80,000 km)
Front suspension and light-body wear
Symptoms: knocking or rattling over bumps, tired struts and bushings, and a bouncy tall-body ride as parts wear on rough roads
What to do: The tall, light kei body puts steady work into the front suspension. Have struts, stabiliser links, ball joints and bushings checked at service and replace worn parts to keep handling and tyre wear in check.
- Worth watching usually from 62,000 mi (100,000 km)
Turbo wear on the turbocharged S07A
Symptoms: loss of boost, whistling or whining from the turbo, blue-tinged exhaust smoke or rising oil use on higher-mileage turbo cars
What to do: Keep to fresh, correct-grade oil and let the turbo idle briefly after a hard run. The little turbo is worked hard in a heavy kei body, so treat any boost loss, smoke or oil consumption as a reason to inspect it early.
- Good to know usually from 25,000 mi (40,000 km)
Idling-stop (auto start-stop) battery wear
Symptoms: auto start-stop stops working, slow cranking, or a battery warning as the special high-load battery ages faster than expected
What to do: The idling-stop system uses a specific heavy-duty battery that wears with the constant restarts and is pricier than an ordinary one — budget for it and fit the correct type, not a standard battery, when it fails.
Service schedule
| Item | Interval | Notes |
|---|---|---|
| Engine oil & filter change | every 6,000 mi (10,000 km) or 12 months | the small 660 cc kei engine (especially the turbo) works hard and does a lot of short-trip city driving — many owners shorten this to ~5000 km |
| Cabin filter | every 9,000 mi (15,000 km) | — |
| Air filter | every 19,000 mi (30,000 km) | — |
| CVT fluid important | every 25,000 mi (40,000 km) | not always listed as scheduled, but regular changes help the kei CVT last in stop-start use |
| Spark plugs (iridium) | every 62,000 mi (100,000 km) | inspect/replace sooner on the turbo |
| Brake fluid important | every 24 months | — |
| Timing chain (no belt) | — | chain-driven — no scheduled belt; investigate any cold-start rattle |
Manufacturer-declared fuel economy
No manufacturer-declared figures for this model are in the Knowledge Base yet. A figure without the cycle it was measured under is not comparable to anything, so we publish none rather than a number you cannot interpret.
