300-series (J300) · 2021–present
3.3 V6 Turbo Diesel · 304 hp · 3.5 V6 Twin-Turbo · 415 hp
Known problems
- Critical
V35A-FTS engine bearing failure (manufacturing debris)
Symptoms: knocking or rough running, in worst cases engine failure; affects a subset of early twin-turbo V6 builds
What to do: A batch of the 3.5 twin-turbo V6 (shared with Tundra and Lexus LX 600) can suffer main-bearing damage from machining debris left in the oil passages during manufacture, and Toyota has recalled/engine-replaced affected vehicles. Check the VIN against open recalls, keep oil-change records, and have any knock investigated immediately.
- Good to know
Diesel DPF regeneration on short trips (F33A-FTV)
Symptoms: warning to complete a regeneration, higher fuel use or reduced performance if regens are repeatedly interrupted
What to do: Like all modern turbo-diesels the F33A relies on periodic diesel-particulate-filter regeneration, which short, cold trips can prevent from completing. Give the vehicle occasional longer runs at temperature and allow active regenerations to finish to avoid a clogged DPF.
Service schedule
| Item | Interval | Notes |
|---|---|---|
| Engine oil & filter change | every 6,000 mi (10,000 km) or 12 months | turbocharged engines dislike extended intervals — halve under severe/short-trip use |
| Cabin filter | every 9,000 mi (15,000 km) | — |
| Air filter | every 25,000 mi (40,000 km) | — |
| Spark plugs (V35A-FTS petrol) | every 37,000 mi (60,000 km) | turbo direct-injection plugs wear faster than an old V8's — shorter interval; diesel has none |
| Brake fluid important | every 36 months | — |
| Timing chain | — | both V6 engines are chain-driven — no scheduled belt replacement |
200-series (J200) · 2007–2021
4.5 V8 Twin-Turbo Diesel · 249 hp · 4.6 V8 · 309 hp · 5.7 V8 · 381 hp
Known problems
- Critical usually from 93,000 mi (150,000 km)
Diesel injector wear and fuel dilution of the oil (1VD-FTV)
Symptoms: rough idle, black smoke, power loss and poor economy; a rising oil level and diesel smell in the oil signal fuel leaking into the sump
What to do: The 1VD-FTV common-rail injectors wear with high pressure and poor fuel, and a leaking injector or nozzle-return line can let diesel drain into the sump. A rising, fuel-diluted oil level is a red flag that can ruin the engine, so use clean fuel, check the oil level (not just condition) between changes, and have injectors tested and replaced at the first sign of leakage.
- Worth watching usually from 25,000 mi (40,000 km)
Brake judder / rotor 'warping'
Symptoms: pulsation felt through the pedal and steering wheel under braking, worse when the brakes are hot
What to do: The heavy 200-series is prone to front brake pulsation, usually from uneven pad-material transfer onto the rotor rather than true warping. Bed pads in properly, avoid holding the pedal after a hard stop, and have rotors machined or replaced when judder appears; it commonly returns without a change in braking habits.
- Worth watching usually from 62,000 mi (100,000 km)
Early diesel oil consumption (pre-2010 1VD-FTV)
Symptoms: higher-than-expected oil use, occasional smoke
What to do: Some earlier twin-turbo diesels burn oil, linked to the vacuum pump and to the oil strainer/pick-up becoming restricted. Keep to clean oil and shorter intervals, monitor consumption, and have the vacuum pump and pick-up checked if it climbs; later engines were improved.
- Worth watching usually from 75,000 mi (120,000 km)
Adaptive/hydraulic suspension (AHC) faults
Symptoms: the vehicle sits low or uneven, will not change ride height, or shows suspension warnings; fluid leaks on AHC-equipped trims
What to do: On AHC-equipped 200-series (Sahara / LX-derived) the hydraulic height system can fail to complete adjustments as it ages, and leaks or worn spheres develop. Have the AHC serviced with correct fluid and repaired by someone familiar with it; conventional-suspension trims avoid this entirely.
Service schedule
| Item | Interval | Notes |
|---|---|---|
| Engine oil & filter change | every 6,000 mi (10,000 km) or 12 months | petrol 0W-20; the 1VD-FTV diesel benefits from shorter ~7,500-10,000 km intervals, and watch the level closely (see fuel-in-oil issue) |
| Cabin filter | every 9,000 mi (15,000 km) | — |
| Air filter | every 25,000 mi (40,000 km) | — |
| Automatic transmission fluid important | every 62,000 mi (100,000 km) | 6-speed auto; replace sooner with heavy towing or off-road use |
| Spark plugs (iridium) | every 62,000 mi (100,000 km) | 1UR-FE / 3UR-FE petrol only |
| Brake fluid important | every 36 months | — |
| Timing chain | — | all 200-series engines (petrol and 1VD-FTV diesel) are chain-driven — no scheduled belt replacement |
100-series (J100) · 1998–2007
4.2 Turbo Diesel · 204 hp · 4.7 V8 · 271 hp
Known problems
- Critical usually from 124,000 mi (200,000 km)
Diesel cylinder head cracking / head gasket failure (1HD-FTE)
Symptoms: overheating, coolant loss, white exhaust smoke, oil-coolant mixing or loss of power after a hard tow or an overheat event
What to do: The 1HD-FTE can crack a cylinder head or blow a head gasket if it has been overheated or worked hard while towing. Keep the cooling system in top condition, address any overheating immediately, and be wary of imported examples with a history of hard use; repair is a major job.
- Worth watching usually from 75,000 mi (120,000 km)
Front lower ball joint wear
Symptoms: clunk or knock over bumps from the front suspension, uneven front tyre wear, vague steering
What to do: The independent front suspension's lower ball joints wear with age and off-road use and, if ignored, can fail. Have them checked at services and replaced once play develops; do not defer this one, as a failed joint affects steering control.
- Worth watching usually from 93,000 mi (150,000 km)
Exhaust manifold cracking (4.7 V8 petrol)
Symptoms: a metallic ticking or tapping on cold start that fades as the engine warms; occasionally an exhaust smell in the cabin
What to do: The thin factory manifolds on the 2UZ-FE, especially 1998-2002 cars, are prone to hairline cracks where the runners meet the flange. It is a noise and emissions nuisance rather than an immediate danger; have the manifold inspected and replaced or welded, and prefer a sturdier aftermarket manifold if it recurs.
- Good to know usually from 93,000 mi (150,000 km)
Diesel intake and intercooler soot/oil fouling (1HD-FTE)
Symptoms: gradual power loss, heavier smoke, oily residue in the intake and intercooler
What to do: Like most turbo-diesels of the era the 1HD-FTE accumulates oil and soot in the intake tract and intercooler over time. Clean the intercooler and intake during major services and keep the EGR/crankcase breather healthy to preserve responsiveness.
Service schedule
| Item | Interval | Notes |
|---|---|---|
| Engine oil & filter change | every 6,000 mi (10,000 km) or 12 months | petrol ~10,000 km; the 1HD-FTE diesel prefers ~7,500-10,000 km and shorter still on dusty or 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) | 2UZ-FE petrol only |
| Timing belt (2UZ-FE petrol) important | every 93,000 mi (150,000 km) | the 4.7 V8 is belt-driven but non-interference, so a snapped belt will not bend valves; replace on schedule anyway. The 1HD-FTE diesel uses gear-driven timing with no belt |
| Brake fluid important | every 36 months | — |
Manufacturer-declared fuel economy
| Engine | City | Highway | Combined | Cycle |
|---|---|---|---|---|
| 5.7 V8 200-series (J200) · 2007–2021 | 13 mpg (18.1 L/100 km) | 18 mpg (13.1 L/100 km) | 15 mpg (15.7 L/100 km) | EPA |
| 4.7 V8 100-series (J100) · 1998–2007 | 12 mpg (19.6 L/100 km) | 15 mpg (15.7 L/100 km) | 13 mpg (18.1 L/100 km) | EPA |
Lab-cycle figures, each shown with the cycle it was measured under — the same car under WLTP, NEDC, EPA or JC08 can differ by up to 20%. Real-world consumption typically runs 15–30% above the declared number, and that gap is normal, not a fault.
