Known Toyota Prado faults
Every fault below is documented specifically for this model — researched and verified before it’s published.
011KD-FTV Intake Manifold Swirl Flap Fracture
CriticalCommonEngine $600–$18,000 to fix
The plastic swirl flaps inside the 1KD-FTV intake manifold are mounted on a thin metal shaft that corrodes and fractures, releasing plastic or metal fragments directly into the combustion chambers. Ingested debris causes catastrophic piston, valve, and cylinder head damage. Toyota removed swirl flaps in revised manifolds after widespread failures; many owners proactively delete the flaps entirely as a preventive measure.
Symptoms to notice
Sudden severe engine knock or rattling noise
Dramatic loss of power under acceleration
Engine warning light with codes related to misfires or multiple cylinder failures
Metal fragments visible in engine oil or on the oil drain plug magnet
Engine hydrolocks or fails to restart after fragments lodge in combustion chamber
What to check
Check for unusual engine knock, loss of compression, or metal shavings in the oil. Confirm whether a swirl flap delete kit has been fitted (look for blanking plates on manifold ports). If a workshop inspection is possible: Remove the air intake hose and inspect inside the intake manifold with a torch for broken or missing flap vanes.
Where to look: Intake manifold — driver's side of the engine, accessible after removing the air intake ducting.
Ask the seller
“Has a swirl flap delete or blanking kit been fitted to the intake manifold?”
“Has the engine ever suffered a sudden power loss or knocking event that required investigation?”
“Can you show a compression test result or recent engine inspection report?”
02Rear Differential Lock Actuator Failure
MinorOccasionalSuspension $500–$1,500 to fix
The rear differential lock on the KDJ150/GRJ150 uses a separate electric actuator mounted on the rear differential housing; this unit is equally susceptible to water ingress and corrosion as the front actuator but is located in a more exposed position near the rear axle. Failure prevents the rear diff lock from engaging, eliminating a key off-road recovery capability. Many failures are caused by moisture tracking along the wiring loom to the connector rather than actuator motor failure alone.
Symptoms to notice
Rear diff lock warning indicator flashes and never confirms engagement
No mechanical clunk from the rear axle when rear lock is activated
Diff lock works intermittently depending on temperature or recent water exposure
Corrosion visible at the rear axle actuator wiring connector
4WD warning light on dash accompanying diff lock failure
What to check
Engage the rear diff lock on a safe surface and confirm the amber lock indicator goes solid within a few seconds. A flashing indicator means failed engagement. Inspect the rear axle actuator connector for corrosion and examine the loom along the axle for chafing or moisture entry points. Check for any 4WD-related fault codes.
Where to look: Rear differential housing — actuator mounted on the top or side of the rear axle, routed under the rear of the vehicle.
Ask the seller
“Can you demonstrate the rear diff lock engaging with the indicator going solid, not just flashing?”
“Has the rear diff lock actuator wiring been inspected or resealed against moisture?”
“Is there any history of the vehicle being driven in salt water, tidal crossings, or beach environments?”

Like any used car, it depends on the specific example and its service history. Across the 57 documented faults for the Toyota Prado, the recurring problem areas are engine, cooling, and fluid leaks. A Toyota Prado with a full service history and no signs of the issues listed on this page can be a sound buy but each one needs to be checked individually before you commit.
What are the most common problems with a used Toyota Prado?
+
We've catalogued 57 known faults for the Toyota Prado, covering engine, cooling, and fluid leaks. Two are written out in full on this page. The rest — with the symptoms to notice, what to inspect, and typical repair costs for each — are free once you create an account.
How much do repairs cost on a Toyota Prado?
+
Most single repairs on the Toyota Prado fall between $700–$2,500 at NZ independent-workshop rates. Some of the 57 documented faults cost less and a few cost considerably more, and no one car needs them all. Knowing which ones to look for before you view is what lets you negotiate the price down or walk away.
Should I get a pre-purchase inspection on a Toyota Prado?
+
Yes. A Toyota Prado inspection focused on its known weak points is the single best way to avoid an expensive mistake. KickTyres gives you a guided, model-specific inspection plus a market valuation and negotiation figure for $17.90 far less than the cost of missing one of the faults on this page.
