01V35A twin-turbo V6 machining-debris main-bearing wear (engine-failure recall)

petrol2022 onwardEngine
OccasionalEngine $2,500–$42,000 to fix

Can't confirm for this car

Early-build LX600 3.5L V35A-FTS twin-turbo V6 engines can retain machining debris from manufacturing that circulates in the oil, wearing the crankshaft main bearings and causing knock, rough running, no-start or a sudden stall with loss of drive. Toyota/Lexus issued a global safety recall covering the shared 300-series powertrain: US NHTSA campaign 24V381000 (Lexus internal 24LB04/24LA04) for ~102,000 Tundra and LX600 units, with a November 2025 expansion adding further 2022-2024 LX600 vehicles. In Australia the campaign covered 789 GX550/LX600 units built 2022-2024; the diesel LX500d is NOT affected. Remedy is a free engine short-block or full engine replacement at a Lexus dealer, so verifying whether the recall was performed is critical.

Symptoms to notice

  • Engine knocking or metallic rattle, especially on start-up or under load
  • Rough running or noticeable loss of power
  • Sudden stall or engine will not start
  • Metallic particles or contamination visible in engine oil

What to check

Run the VIN through Lexus for recall status and confirm whether the engine-debris recall (NHTSA 24V381000 / Lexus 24LB04) has been completed or is outstanding; on a low-km early build (roughly the first 20,000-40,000 km) listen for cold-start knock, check for a replaced/updated engine, and inspect oil condition and service history for any bearing-related work.

Where to look: Engine, crankshaft main bearings / lubrication system

Parts involved: Turbocharger.

Ask the seller

  • “Has the V35A engine-debris recall been carried out, and do you have the dealer paperwork?”
  • “Was the original engine replaced or is it the factory unit?”
  • “Have you ever heard knocking or had a stall or no-start event?”
  • “Is the full Lexus service history available showing oil changes on schedule?”

02V35A engine recall — manufacturing debris destroys the main bearings

petrol2022–2023Engine
OccasionalEngine $0–$25,000 to fix

Can't confirm for this car

Lexus recalled LX models fitted with the V35A twin-turbo V6 because debris left behind during manufacturing can contaminate the engine and cause the main bearings to fail. The consequence is the engine stalling and the vehicle losing drive power, which on a large four-wheel drive at open-road speed is a serious matter. This is not wear and it is not something a careful owner can prevent — the debris was in the engine when it left the factory — so mileage, service history and condition tell you nothing about the risk. The only thing that does is whether the campaign has been carried out on this specific vehicle, which a dealer will confirm against the VIN for free. On an imported LX that check matters more, not less.

Symptoms to notice

  • Knock or rumble from the bottom of the engine, worst on start-up
  • Engine stalling, or a sudden loss of drive power while driving
  • Oil pressure warning light, especially at hot idle
  • Metallic glitter or shards in the oil or on the drain plug
  • Often nothing at all until the bearing lets go

What to check

  1. Take the VIN from the base of the windscreen or the driver's door jamb and ask a Lexus dealer whether the V35A engine campaign and any other outstanding one has been completed — this is the check that matters and it is free, because nothing about the vehicle's condition tells you anything here.
  2. Ask the seller for dealer invoices and read them, and ask whether the vehicle was imported and whether it has been to a Lexus dealer in New Zealand.
  3. Then be there for a stone-cold start: stand at the front with the bonnet up as it fires and listen to the BOTTOM of the engine rather than the top, for a deep knock or rumble in the first seconds even if it fades.
  4. Let it idle to temperature and watch the dash constantly for the oil pressure light, since a flicker at hot idle is significant.
  5. Take the oil filler cap off and look at the underside, and check the oil on the dipstick for a metallic glitter in the film.
  6. Ask directly whether the engine has ever stalled or lost power.
  7. If a workshop inspection is possible: an oil analysis is the test that finds bearing material before the bearing fails.

Where to look: Bottom of the engine — crankshaft main bearings

Parts involved: Turbocharger.

Ask the seller

  • “Has the V35A engine recall been completed, and can I see the dealer invoice?”
  • “Has the engine ever stalled or lost power while driving?”
  • “Was the vehicle imported, and has it been to a Lexus dealer here?”

0310-speed auto brake-clutch disc slow neutral disengagement (vehicle-creep recall)

Check the VIN for the Lexus Australia transmission-ECU recall and confirm the reprogram was completed.2022 onwardTransmission
OccasionalTransmission $250–$6,000 to fix

Can't confirm for this car

A brake clutch disc inside the Aisin 10-speed automatic (shared with the 300-series Land Cruiser) may not immediately disengage when Neutral is selected, allowing the vehicle to creep forward at up to about 6 km/h if the driver does not hold the brake or parking brake, an unintended-movement/rollaway risk. Lexus Australia recalled roughly 1,350 LX500d and LX600 vehicles produced 10 December 2021 to 10 January 2024 for this; the remedy is a free transmission ECU software reprogram at a Lexus dealer. Because both petrol LX600 and diesel LX500d are covered, confirm the reflash has been applied and check for any driveline damage from creep events.

Symptoms to notice

  • Vehicle creeps forward in Neutral without throttle
  • Delay or hesitation shifting into or out of Neutral
  • Faint driveline engagement noise when selecting Neutral
  • Warning of unintended movement when parked without parking brake

What to check

Check the VIN for the Lexus Australia transmission-ECU recall and confirm the reprogram was completed; on the test drive select Neutral on a slight incline (foot ready on the brake) to confirm the vehicle does not creep, and confirm the 10-speed shifts smoothly with no harshness or slip.

Where to look: 10-speed automatic transmission (brake clutch disc) / transmission ECU

Parts involved: Clutch.

Ask the seller

  • “Has the transmission ECU reprogram recall been completed on this vehicle?”
  • “Have you ever noticed the car creeping when in Neutral?”
  • “Is the transmission software up to date per the recall notice?”
  • “Any harsh shifts or transmission warning lights?”

012UZ-FE Timing Belt Failure

Confirm service history shows timing belt replacement at or before 100,000 km intervals.petrol1998–2007Engine
OccasionalEngine $1,400–$2,800 to fix

Does not apply

Unconfirmed. This entry does not match our record of which engines and years this model was sold with, and is awaiting review. Confirm it against the car before acting on it.

The 4.7L V8 2UZ-FE is an interference engine requiring timing belt replacement every 100,000 km. Belts on high-mileage Japanese imports frequently present at or beyond service life. Belt failure causes catastrophic valve and piston contact. Water pump, tensioner, and idler pulleys must be replaced simultaneously as labour costs are shared. Many LX470s arrive in NZ/AU with no documented belt history.

Symptoms to notice

  • Engine fails to start or cranks without firing after belt failure
  • Visible belt fraying, cracking, or glazing at inspection
  • High-pitched squealing under load if tensioner bearing is failing

What to check

Confirm service history shows timing belt replacement at or before 100,000 km intervals. On unknown-history imports, budget for immediate replacement. Ask for receipts rather than verbal assurance. If a workshop inspection is possible: Remove the inspection cover and check belt condition.

Where to look: Front of engine behind plastic cover on the driver's side of the engine bay

Parts involved: Timing belt.

Ask the seller

  • “Can you provide receipts showing timing belt replacement?”
  • “What is the current odometer reading versus the last belt service?”
  • “Has the water pump and tensioner been replaced at the same time?”

028-Speed Automatic Torque Converter Lock-Up Shudder

Drive at constant 80 km/h on a flat road under light throttle and note any vibration through the drivetrain.petrol2007–2021Transmission
OccasionalTransmission $400–$4,500 to fix

Does not apply

The AA80E 8-speed automatic fitted to LX570 models develops torque converter shudder caused by the lock-up clutch slipping due to ATF degradation or incorrect fluid specification. The symptom is a vibration felt through the drivetrain during light-throttle cruising in the 60–100 km/h range. A full ATF flush using Toyota-specified WS fluid often resolves early cases. Delayed service allows clutch material to wear into the fluid, contaminating the valve body and requiring torque converter replacement.

Symptoms to notice

  • Vibration or judder felt through the floor and seat during steady light-throttle driving at 60–100 km/h
  • Symptom disappears under firm acceleration or when the transmission kick-down unlocks the converter
  • Transmission fluid appears dark brown or smells burnt

What to check

  1. Drive at constant 80 km/h on a flat road under light throttle and note any vibration through the drivetrain.
  2. Request full transmission service history.
  3. Check ATF colour and smell.
  4. Scan for transmission fault codes including slip-related codes.

Where to look: Torque converter between engine and transmission at the front of the gearbox bell housing

Parts involved: Torque converter.

Ask the seller

  • “Has the transmission fluid been changed and at what odometer reading?”
  • “Have you noticed any vibration or shudder during motorway cruising?”
  • “Has the transmission been serviced with Toyota WS fluid specifically?”

033UR-FE secondary air injection pump failure

Scan for secondary air injection codes, listen at cold start, and inspect the air switching valves for corrosion.petrol2008–2021Engine
CommonEngine $800–$3,500 to fix

Does not apply

The LX570's 5.7 3UR-FE V8, like the Tundra/Sequoia, suffers secondary air injection pump and valve corrosion, throwing P2440-series codes and a CEL. A common and costly fault on these luxury 4WDs.

Symptoms to notice

  • CEL with secondary air codes
  • Rough cold-start running
  • Loud pump noise at cold start
  • Emissions faults

What to check

Scan for secondary air injection codes, listen at cold start, and inspect the air switching valves for corrosion.

Where to look: Secondary air injection pumps and valves on the engine

Parts involved: High-pressure fuel pump.

Ask the seller

  • “Any secondary air codes or CEL?”
  • “Have the air pumps or valves been done?”
  • “Any emissions issues?”

04Secondary Air Injection Pump Failure (VSC and CEL Fault)

Inspect secondary air pump housing for cracks or water ingress.petrol1998–2007Engine
CommonEngine $600–$1,600 to fix

Does not apply

Unconfirmed. This entry does not match our record of which engines and years this model was sold with, and is awaiting review. Confirm it against the car before acting on it.

The 2UZ-FE uses a secondary air injection system to reduce cold-start emissions. The electric pump and associated check valves deteriorate on high-mileage vehicles, failing to deliver air to the exhaust manifold. This triggers a P0410 or P0411 fault, illuminating the Check Engine Light and typically the VSC and TRAC lights simultaneously as they share the same warning cluster. Diagnosis must distinguish between pump failure, check valve failure, and perished vacuum hoses, which have different repair costs.

Symptoms to notice

  • Check Engine Light active with VSC and TRAC lights lit simultaneously
  • P0410 or P0411 fault code stored
  • No driveability change but vehicle may fail NZ WOF emissions inspection

What to check

  1. Inspect secondary air pump housing for cracks or water ingress.
  2. Check vacuum hoses at the air switching valve for perishing.
  3. Test pump operation with direct 12V connection to confirm pump motor function.
  4. If a workshop inspection is possible: OBD scan for P041x codes before purchase.

Where to look: Secondary air pump mounted in engine bay on the passenger side; check valves and vacuum lines at the rear of the intake manifold

Parts involved: High-pressure fuel pump.

Ask the seller

  • “Has the Check Engine Light been on at any point?”
  • “Has an OBD scan been done – are there any stored fault codes?”
  • “Has the secondary air injection system been repaired or replaced?”

05Starter motor failure under the intake manifold

Test several hot and cold starts for reliable cranking, and ask if the starter has ever been replaced given the labour involved.petrol2008–2021Engine
OccasionalEngine $600–$1,800 to fix

Does not apply

The LX570/Tundra 5.7 V8 mounts the starter in the engine valley under the intake manifold, and when it fails the intake must come off to replace it, making an otherwise routine job labour-intensive and costly.

Symptoms to notice

  • Intermittent no-crank / click on start
  • Slow or hesitant cranking
  • Starter noise
  • No-start when hot

What to check

Test several hot and cold starts for reliable cranking, and ask if the starter has ever been replaced given the labour involved.

Where to look: Starter motor in the engine valley under the intake manifold

Parts involved: Intake manifold, Starter motor.

Ask the seller

  • “Has the starter ever failed or been replaced?”
  • “Any hesitation when starting hot?”
  • “Any intermittent no-crank?”

01Height-control / hydraulic suspension (AHC) failure

Cycle the height control through its settings, check for leaks at the AHC spheres and lines, and scan for suspension codes.2008–2021Suspension
OccasionalSuspension $800–$5,000 to fix

Does not apply

The LX570's Adaptive Height Control and hydraulic suspension leaks and fails with age, causing sagging, harsh ride and warning messages. AHC repairs are complex and expensive, a key check on used examples.

Symptoms to notice

  • Vehicle sagging or uneven height
  • Suspension warning message
  • Harsh or bouncy ride
  • Height adjustment not working

What to check

Cycle the height control through its settings, check for leaks at the AHC spheres and lines, and scan for suspension codes.

Ask the seller

  • “Does the height control work through all modes?”
  • “Any AHC leaks or repairs?”
  • “Any suspension warnings?”
Fluid leaks2

01Rear Differential Breather Blockage Causing Seal Blow-Out and Oil Loss

Inspect rear diff housing and both axle flange areas for oil staining from beneath the vehicle.petrol2007–2021Fluid Leaks
OccasionalFluid Leaks $250–$900 to fix

Does not apply

On LX570 and 200 Series Land Cruiser platforms, the rear differential breather hose routes to the top of the diff housing. Mud, dirt, and grime block the breather over time — particularly on NZ/AU vehicles used for any off-road driving. A blocked breather causes internal pressure to build during normal operation, eventually blowing the diff output shaft seals. Oil leaks from the rear axle flanges appear, leading to diff oil starvation if not caught. Breather cleaning is a cheap preventive fix; seal replacement is moderate cost.

Symptoms to notice

  • Oil residue or staining around rear axle flanges or diff housing
  • Diff oil level dropping
  • Smell of gear oil from rear of vehicle during or after driving
  • In advanced cases, whining or rumbling from rear diff under load

What to check

  1. Inspect rear diff housing and both axle flange areas for oil staining from beneath the vehicle.
  2. Locate the diff breather hose (routes up inside the chassis on LX570) and check for blockage or compression.
  3. Check rear diff oil level.
  4. On any used LX570 used off-road, breather cleaning is advisable.

Where to look: Rear differential housing, output shaft seals at both rear axle flanges, breather hose routed up inside chassis rail

Parts involved: Differential.

Ask the seller

  • “Has the vehicle been used off-road or through water?”
  • “Any oil leaks near the rear axle or diff?”
  • “When was the rear differential oil last changed?”

02Front differential pinion seal leak

Inspect the front diff pinion seal and flange for weep and check diff oil level.petrol2008–2021Fluid Leaks
OccasionalFluid Leaks $250–$900 to fix

Does not apply

The LX570 front diff pinion seal weeps gear oil onto the front driveshaft flange, common on high-km 4WDs. Left unchecked it lowers diff oil and can damage bearings.

Symptoms to notice

  • Oil film on front diff pinion flange
  • Gear oil drips under front axle
  • Low diff oil
  • Diff whine if run low

What to check

Inspect the front diff pinion seal and flange for weep and check diff oil level.

Where to look: Front differential pinion seal

Parts involved: Differential.

Ask the seller

  • “Any diff seal leaks?”
  • “When was the diff oil serviced?”
  • “Is it used off-road?”
