4th gen (LA650/LA660, DNGA) · 2019–present
0.66 KF (NA) · 52 hp · 0.66 KF turbo · 64 hp
Known problems
- Worth watching usually from 50,000 mi (80,000 km)
Power sliding door mechanism wear
Symptoms: a power sliding door (now on both sides) that slows, sticks, or needs a manual assist as it ages
What to do: Keep the tracks and rollers clean and lubricated and have the door motor, cables and pinch sensors checked if operation slows — power-door repairs are among the costlier items on the car.
- Good to know
2023 Daihatsu safety-certification testing irregularities (context)
Symptoms: not a mechanical fault of the car — a corporate-conduct issue disclosed in 2023
What to do: Be aware that in 2023 Daihatsu disclosed it had irregularly conducted certain safety-certification tests (including side-collision and airbag tests) over many years, which triggered a temporary production and shipment halt. Independent investigation and re-testing reported the affected vehicles still met occupant-protection standards. Factor it as background, not as a specific defect of an individual car.

D-CVT — service the fluid, limited long-term history
Symptoms: no widespread failure pattern yet; the concern is neglected fluid on this newer split-gear transmission leading to shudder or wear at high mileage
What to do: Keep the D-CVT fluid serviced on schedule (sooner under heavy city/heat use) and have any shudder or hesitation checked early. This split-gear "dual-mode" CVT debuted on this generation, so long-term durability data is still building — treat fluid care as the main preventive step.

KF oil consumption / chain-cover weep (watch item)
Symptoms: possible minor oil seepage at the timing-chain cover and a modestly rising oil appetite at higher mileage
What to do: Check the oil level regularly and keep fresh, correct-grade oil in it. Carries over the KF family's tendency; still a watch item on this newer generation.
Service schedule
| Item | Interval | Notes |
|---|---|---|
| Cabin filter | every 9,000 mi (15,000 km) | — |
| Engine oil & filter change | every 9,000 mi (15,000 km) or 12 months | shorten to ~5000-7500 km for short-trip/city use, sooner on the turbo |
| Air filter | every 19,000 mi (30,000 km) | — |
| D-CVT fluid important | every 37,000 mi (60,000 km) | the DNGA D-CVT adds a mechanical split gear; treat the fluid as serviceable (roughly 50k under severe use, up to ~100k normal) rather than fill-for-life |
| Spark plugs | every 62,000 mi (100,000 km) | iridium on the NA; halve on the turbo |
| Brake fluid important | every 24 months | — |
| Timing chain (no belt) | — | chain-driven KF — no scheduled belt; keep oil fresh and investigate cold-start rattle |
3rd gen (LA600/LA610) · 2013–2019
0.66 KF (NA) · 52 hp · 0.66 KF turbo · 64 hp
Known problems
- Worth watching usually from 37,000 mi (60,000 km)
CVT judder / longevity depends on fluid
Symptoms: a slight shudder or juddering at higher rpm, or hesitation and lost smoothness as mileage climbs, especially if the fluid has never been changed
What to do: Change the CVT fluid on a sensible interval (roughly every 40k, sooner under heavy city or hot-climate use) rather than treating it as fill-for-life. Have any persistent shudder or slipping diagnosed before it worsens.
- Worth watching usually from 50,000 mi (80,000 km)
KF timing-chain-cover oil weep and oil use
Symptoms: minor oil seepage around the timing-chain cover or valve cover, and a gradually rising appetite for oil between changes on higher-mileage engines
What to do: Check the oil level regularly and keep to fresh, correct-grade oil — the chain relies on clean oil and a clear oil jet. Have any weeping cover seals resealed before they drip onto belts or the exhaust.
- Worth watching usually from 50,000 mi (80,000 km)
Power sliding door mechanism wear
Symptoms: a power sliding door that opens/closes slowly, sticks part-way, needs a manual nudge, or stops responding to the switch as the car ages; the pillarless "Miracle Open Door" left side is the most used
What to do: Keep the door tracks and rollers clean and lubricated, and have the drive motor, cables and pinch sensors checked if the door slows or hesitates — parts and labour for the power door are among the pricier repairs on this car.
- Good to know
Tall-kei stability, noise and light construction
Symptoms: sensitivity to crosswinds and lorry wash at motorway speed, noticeable body lean, and a fair amount of road and engine noise from the light, thin-panelled body
What to do: Ease off in strong side winds and leave more braking margin — this is a tall, light 660cc city car, not a motorway cruiser. Its small footprint and light structure also offer less crash protection than a larger car, so drive defensively.
Service schedule
| Item | Interval | Notes |
|---|---|---|
| Cabin filter | every 9,000 mi (15,000 km) | — |
| Engine oil & filter change | every 9,000 mi (15,000 km) or 12 months | a small hard-working 660cc triple — shorten to ~5000-7500 km for mostly short-trip/city use, and sooner on the turbo |
| Air filter | every 19,000 mi (30,000 km) | — |
| CVT fluid important | every 25,000 mi (40,000 km) | Daihatsu's own CVT lasts well on fresh fluid; many owners do a partial change every ~20-40k with a pan clean under city/heat use |
| Spark plugs | every 62,000 mi (100,000 km) | iridium on the NA; roughly halve the interval on the turbo |
| Brake fluid important | every 24 months | — |
| Timing chain (no belt) | — | the KF is chain-driven — no scheduled belt; keep the oil fresh and 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.
