4th gen (R90 / ZWR90) · 2022–present
1.8 Hybrid · 140 hp · 2.0 · 170 hp
Known problems
- Good to know
Hybrid EGR upkeep on the carried-over 1.8
Symptoms: no faults expected early, but the 1.8 hybrid still uses cooled EGR that can carbon up over very high mileage
What to do: The hybrid engine is a refined version of the earlier 1.8, and later 2ZR-FXE units largely tamed the EGR-clogging issue — but on a high-use car an EGR/intake clean is still worthwhile preventive maintenance, and any misfire is worth acting on early.
- Good to know
Power sliding door care
Symptoms: as on the earlier Noah, the power doors depend on healthy sensors, clean tracks and a good 12V battery
What to do: The R90 is recent with little long-term history, so treat this as preventive: keep the door tracks clean, the sensors clear and the 12V battery healthy, and report any door hesitation while under warranty.
Service schedule
| Item | Interval | Notes |
|---|---|---|
| Engine oil & filter change | every 6,000 mi (10,000 km) or 12 months | halve under severe, city or short-trip use |
| Cabin filter | every 9,000 mi (15,000 km) | — |
| Air filter | every 25,000 mi (40,000 km) | — |
| CVT / e-CVT fluid important | every 37,000 mi (60,000 km) | 2.0 uses a Direct-Shift CVT, the hybrid an e-CVT |
| Spark plugs (iridium) | every 62,000 mi (100,000 km) | — |
| Brake fluid important | every 36 months | — |

3rd gen (R80 / ZRR80 / ZWR80) · 2014–2021
1.8 Hybrid · 136 hp · 2.0 · 152 hp
Known problems
- Worth watching usually from 50,000 mi (80,000 km)
Power sliding door faults
Symptoms: power door won't open or close from the button, stops or reverses partway, or works only intermittently; often just one side
What to do: Cycle both power doors several times when buying and at service. Trouble usually traces to a weak 12V battery, dirty obstacle sensors, dirt in the tracks or a worn door harness rather than the motor — clean the tracks, clear the sensors and check the battery first.
- Worth watching usually from 75,000 mi (120,000 km)
Suspension and bushing wear on a loaded MPV
Symptoms: knocks over bumps, tired dampers, worn bushings and uneven tyre wear on higher-mileage cars
What to do: Typical for a family minivan that carries loads. Have the suspension inspected at service and renew worn dampers, arms and bushings to keep ride quality and tyre wear in check.
- Worth watching usually from 81,000 mi (130,000 km)
Hybrid EGR cooler and valve carbon clogging (2ZR-FXE)
Symptoms: rough or unstable idle, misfires, hesitation and warning lights (often an EGR insufficient-flow code) as the fine EGR-cooler passages and valve fill with carbon
What to do: The main thing to watch on the 1.8 hybrid: the cooled-EGR passages slowly clog with hard carbon, which if ignored can cause misfires and, in bad cases, contribute to head-gasket trouble. Have the EGR cooler, valve and intake passages cleaned as preventive maintenance and deal with any misfire or coolant loss promptly.
- Good to know usually from 93,000 mi (150,000 km)
Hybrid 12V and HV battery ageing
Symptoms: the small 12V battery weakens with age (no-start, electrical quirks); the high-voltage battery slowly loses capacity, and a clogged HV-battery cooling-fan filter can let it run warm
What to do: Keep the 12V battery healthy — a weak one causes many odd faults on a hybrid. Periodically clean the HV-battery cooling intake/filter (near the rear seats) so the pack stays cool, and budget for eventual HV-battery service on very high-mileage cars.
Service schedule
| Item | Interval | Notes |
|---|---|---|
| Engine oil & filter change | every 6,000 mi (10,000 km) or 12 months | halve under severe, city or short-trip use |
| Cabin filter | every 9,000 mi (15,000 km) | — |
| Air filter | every 25,000 mi (40,000 km) | — |
| CVT / e-CVT fluid important | every 37,000 mi (60,000 km) | 2.0 uses a Super CVT-i, the hybrid an e-CVT; a fluid change every ~40-60k km helps CVT longevity under load |
| Spark plugs (iridium) | every 62,000 mi (100,000 km) | — |
| Brake fluid important | every 36 months | — |
| Timing chain | — | both engines are 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.

Frequently asked
What are the most common Toyota Noah problems?
The faults reported most often are: Power sliding door faults; Suspension and bushing wear on a loaded MPV; Hybrid EGR cooler and valve carbon clogging (2ZR-FXE). Symptoms, the mileage each appears at and what to do about it are all above.
How often does the Toyota Noah need servicing?
Engine oil & filter change — every 6,000 mi (10,000 km) or 12 months. The full published schedule is above; your car's own service book always takes precedence.
Where does this data come from?
Brimly's Vehicle Knowledge Base — the same verified facts the app's AI assistant answers from. Every fault is written up from public sources and then checked by a human before it is published; nothing here is generated on the fly.
