Known Lexus Windom faults
Every fault below is documented specifically for this model — researched and verified before it’s published.
012AZ-FE 2.4 head bolt thread pull-out from aluminium block
CriticalOccasionalEngine $1,800–$4,500 to fix
The 2AZ-FE 2.4-litre four-cylinder fitted to XV40 ES240 variants suffers a documented head bolt thread pull-out defect where the aluminium cylinder block threads strip under repeated thermal cycling, allowing coolant and combustion gas crossover. Toyota issued a special warranty coverage extension for this specific defect. NZ and AU examples outside warranty require helicoil thread repair or engine replacement.
Symptoms to notice
Coolant level dropping without any visible external leak
White steam or sweet exhaust smell from the tailpipe
Milky or frothy oil on the dipstick indicating coolant contamination
Temperature gauge rising toward overheat or overheating events
Bubbling visible in the coolant reservoir when the engine is running
What to check
Check the coolant reservoir for a milky or oily contamination line. Inspect the oil dipstick for frothy or light-coloured oil. Check exhaust for persistent white steam under load on a warm engine. If a workshop inspection is possible: Have a cooling system pressure test performed — internal leakage will be evident.
Where to look: Cylinder head to block joint, 2AZ-FE 2.4-litre four-cylinder engine
Ask the seller
“Any unexplained coolant loss or regular top-up needed?”
“Has the cylinder head or head gasket been off this engine for any reason?”
“Any overheating events in the vehicle history?”
02Front lower control arm ball joint premature wear
MajorOccasionalSuspension $400–$900 to fix
XV70 ES300h front lower control arm ball joints have been reported by owners and independent mechanics to wear earlier than expected for a vehicle in the premium segment. The ball joint boot compound degrades in NZ and AU conditions, allowing water ingress that accelerates joint wear. Owner forum reports from 60,000 to 100,000 km examples document this as a recurring WOF-time item on NZ-registered XV70 ES models.
Symptoms to notice
Clunking or knocking from the front suspension over bumps or rough surfaces
Slight wandering or vagueness in the steering at highway speeds
Uneven tyre wear across the front axle
WOF advisory or failure for front suspension component play
What to check
Inspect the ball joint boot on both sides for cracking or grease expulsion which indicates the joint is running dry. Check both sides as wear is often bilateral on this platform. If a workshop inspection is possible: With the vehicle on a hoist, lever the front lower control arm upward and check for ball joint vertical play.
Where to look: Front lower control arm ball joints, both driver and passenger sides
Ask the seller
“Have the front lower control arms or ball joints been replaced or inspected?”
“Any WOF advisories or failures related to front suspension?”
“Any clunking over bumps or looseness in the steering?”
