Known problems
- Good to know
Diesel DPF regeneration on short trips (2.8 1GD-FTV)
Symptoms: prompts to complete a regeneration, higher fuel use if regens are repeatedly cut short
What to do: The carried-over 2.8 diesel needs periodic particulate-filter regeneration, which short cold trips can interrupt. Give the vehicle occasional longer runs at temperature and let active regenerations finish to avoid DPF clogging. The 250-series is new, so long-term fault history is still limited.
Service schedule

2.7 Petrol · 163 hp · 2.8 D-4D Diesel · 177 hp · 3.0 D-4D Diesel · 173 hp · 4.0 V6 · 282 hp
Known problems
- Critical usually 62,000–93,000 mi (100,000–150,000 km)
Cracked pistons on early diesel (1KD-FTV, 2009-2014)
Symptoms: power loss, rough running, blow-by or smoke
What to do: Early 150-series with the 1KD-FTV carry over the Euro IV cracked-piston risk, typically 100,000-150,000 km and often linked to injector faults. Toyota introduced stronger pistons and improved injectors in 2014, so later 1KD and the 2.8 1GD are far less affected; on an early diesel, keep injectors healthy and investigate power loss/smoke early.
- Worth watching usually from 19,000 mi (30,000 km)
Diesel particulate filter clogging (2.8 1GD-FTV, 2015-2017)
Symptoms: DPF warnings, forced/limp-mode regenerations, higher fuel use, sometimes oil-level rise from post-injection fuel
What to do: Early 2.8 1GD-FTV Prados (2015-2017) were prone to DPF clogging under lower-speed/short-trip use; Toyota released an ECU update (service campaign) to raise exhaust temperature and lengthen the regeneration cycle. Ensure the campaign reflash is done, give the car regular longer runs, and let regenerations complete.
- Worth watching usually from 75,000 mi (120,000 km)
Diesel injector wear (1KD-FTV / 1GD-FTV)
Symptoms: rough idle, smoke, poor economy, hard starting
What to do: Common-rail injectors wear with mileage, fuel quality and high injection pressures. Use clean fuel, change the fuel filter on schedule, and have injectors tested and replaced when symptoms appear — worn injectors can over-fuel and damage pistons.
- Good to know usually from 75,000 mi (120,000 km)
Diesel EGR and intake carbon build-up
Symptoms: gradual power loss, hesitation, sooty EGR valve and intake manifold
What to do: As with most modern diesels, soot builds up in the EGR system and intake over time. Clean during major services and keep the breather system clear to preserve response.
Service schedule
| Item | Interval | Notes |
|---|---|---|
| Engine oil & filter change | every 6,000 mi (10,000 km) or 12 months | diesels prefer shorter ~7,500-10,000 km with quality oil; halve under dusty/short-trip use |
| Cabin filter | every 9,000 mi (15,000 km) | — |
| Air filter | every 25,000 mi (40,000 km) | shorten in dusty/off-road conditions |
| Fuel filter (diesel) important | every 25,000 mi (40,000 km) | critical for common-rail injector life; use quality fuel |
| Spark plugs (iridium) | every 62,000 mi (100,000 km) | 2TR-FE / 1GR-FE petrol only |
| Brake fluid important | every 36 months | — |
| Timing chain | — | petrol and diesel engines are all chain-driven — no scheduled belt replacement |
120-series (J120) · 2002–2009
2.7 Petrol · 163 hp · 3.0 D-4D Diesel · 166 hp · 4.0 V6 · 249 hp
Known problems
- Critical usually 62,000–93,000 mi (100,000–150,000 km)
Cracked pistons (1KD-FTV diesel)
Symptoms: power loss, rough running, blow-by or white/grey smoke; in severe cases coolant or oil contamination
What to do: The Euro IV 1KD-FTV is known to crack pistons, most often between roughly 100,000 and 150,000 km, frequently downstream of a leaking or over-fuelling injector. Keep injectors in good order, use clean fuel and quality oil, and investigate power loss or smoke early; Toyota reshaped the pistons and oil jets to reduce it, but it remains a costly repair.
- Worth watching usually 62,000–87,000 mi (100,000–140,000 km)
Diesel injector failure and copper seat/washer leaks (1KD-FTV)
Symptoms: rough idle, black smoke, poor economy; white smoke and a diesel-in-oil smell when injector copper seats leak
What to do: The 1KD-FTV common-rail injectors wear (often around 120,000-140,000 km) and the copper seat washers, especially on 2004-2007 cars, can leak combustion gases and let fuel past. Have injectors tested and reseated/replaced at the first symptoms; a bad injector is also a leading cause of the cracked-piston failure above, so do not delay.
- Worth watching usually from 75,000 mi (120,000 km)
Diesel EGR and intake carbon build-up (1KD-FTV)
Symptoms: gradual power loss, heavier smoke, hesitation; sooty intake manifold and EGR valve
What to do: The EGR valve and intake tract clog with soot and oil mist over time, restricting airflow. Clean the EGR and intake during major services and keep the crankcase breather clear to maintain response and economy.
- Good to know
Dashboard cracking / trim shrinkage
Symptoms: cracks or splits appearing in the dash top and trim, more common in hot, sunny climates
What to do: The 120-series dashboard can crack with age and heat. It is cosmetic; a dash cover or a replacement/reconditioned panel resolves it, and parking in shade slows it.
Service schedule
| Item | Interval | Notes |
|---|---|---|
| Engine oil & filter change | every 6,000 mi (10,000 km) or 12 months | the 1KD-FTV diesel prefers shorter ~7,500-10,000 km intervals with quality oil; halve under dusty/short-trip use |
| Cabin filter | every 9,000 mi (15,000 km) | — |
| Air filter | every 25,000 mi (40,000 km) | shorten in dusty/off-road conditions |
| Automatic transmission fluid important | every 62,000 mi (100,000 km) | replace sooner with towing or heavy off-road use |
| Spark plugs (iridium) | every 62,000 mi (100,000 km) | 2TR-FE / 1GR-FE petrol only |
| Brake fluid important | every 36 months | — |
| Timing chain | — | 2TR-FE, 1GR-FE and 1KD-FTV are all chain-driven — no scheduled belt replacement |
