M900 (Daihatsu Thor-based; also sold as Tank) · 2016–present
1.0 · 69 hp · 1.0 Turbo · 98 hp
Known problems
- Worth watching usually from 37,000 mi (60,000 km)
CVT behaviour and fluid neglect
Symptoms: rubber-band feel under acceleration, low-speed shudder, jerks or slipping on cars where the CVT fluid was never changed
What to do: The Daihatsu-built CVT is reliable with fresh fluid but sensitive to old, overheated fluid. Change it around every 40,000 km, avoid harsh launches and prolonged wheelspin, and have any shudder or hesitation checked early.
- Good to know
Daihatsu certification-test scandal (built by Daihatsu)
Symptoms: not a mechanical fault — the Roomy/Tank is a rebadged Daihatsu Thor, and in 2023 Daihatsu admitted irregularities in its certification and safety testing across many models
What to do: This concerns test/certification procedures rather than a confirmed defect in your car, and Toyota/Daihatsu conducted re-verification. Keep an eye on any official recall notices for your VIN and have them actioned; otherwise service the car normally.
- Good to know
Light build and road noise
Symptoms: audible road and wind noise and light, easily-marked panels typical of a small budget tall-wagon
What to do: Expected for the class rather than a defect. Treat stone chips promptly to avoid rust; added sound insulation improves comfort if desired.
- Good to know usually from 50,000 mi (80,000 km)
1.0 turbo three-cylinder — maintenance sensitivity
Symptoms: characteristic three-cylinder idle vibration; on the turbo, sensitivity to oil quality and heat, with turbo and mounts as the main wear concerns at higher mileage
What to do: Some idle buzz from the three-cylinder is normal. On the 1KR-VET turbo keep the oil fresh and let it idle briefly before shutting down after hard runs to protect the turbo; check engine mounts if vibration worsens.
Service schedule
| Item | Interval | Notes |
|---|---|---|
| Engine oil & filter change | every 6,000 mi (10,000 km) or 12 months | halve for the turbo and under severe/short-trip use |
| Cabin filter | every 9,000 mi (15,000 km) | — |
| Air filter | every 25,000 mi (40,000 km) | — |
| CVT fluid important | every 25,000 mi (40,000 km) | change around every 40,000 km to avoid slip/shudder — the box is sensitive to old fluid |
| Spark plugs (iridium) | every 62,000 mi (100,000 km) | inspect the turbo car's plugs sooner |
| Brake fluid important | every 36 months | — |
| Timing chain | — | chain-driven — no scheduled belt replacement |
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.
