What to look out for

The checks worth doing on a Kia Carnival before you hand over any money. Every documented fault is listed below, each with its own page.

  • Costly issue

    Operate both sliding doors multiple times via interior button, exterior button, and key fob.

    See why

    Power Sliding Door Motor and Roller Track Failure

    All generations of Carnival power sliding door systems are prone to motor failure, roller wear, and track debris causing doors to stall mid-travel, refuse to open or close, or slam shut unexpectedly. The motors are underpowered for the door weight in later KA4 models. Roller assemblies crack and seize. Child-safety implications when doors behave unexpectedly. The fault affects both left and right doors independently and is among the most consistently reported issues across all Carnival generations on owner forums.

    What you would notice

    • Sliding door stalls or stops mid-travel
    • Door refuses to open or close via button or remote
    • Grinding or clicking noise from door track during operation
    • Door closes too slowly or reverses unexpectedly
    • Error message or warning chime related to sliding door

    Typically $450–$1,100 to put right.

  • Costly issue

    Cycle both sliding doors several times from the key fob, the B-pillar button and the dash switch.

    See why

    Power sliding door failures - motors, latches and cable mechanisms (all generations)

    Every Carnival generation sold in NZ/AU has a documented history of power sliding door trouble: worn cables and motors on VQ (2006-2014), doors that pinch or fail to reverse on YP (US recall on the equivalent Sedona), and a KA4 recall for release actuators that stop the right-side door latching securely (about 3000 Australian cars from the July-October 2021 build, plus a 2025 recall for the passenger-side door remote controller). Symptoms are doors that stall, jam, beep and re-open, or won't latch. Repairs to motors, cables and latch actuators are labour-heavy.

    What you would notice

    • Door stops midway and reverses
    • Continuous beeping and door-ajar warning while driving
    • Door won't respond to button or key fob
    • Grinding noise from the door track

    Typically $400–$2,000 to put right.

  • Common issue

    Test the rear climate control through all fan speed settings with both heating and cooling active.

    See why

    Rear HVAC Blower Motor Failure

    The rear-zone climate blower motor in the Carnival ceiling unit is known to fail due to brush wear in the DC motor and deterioration of the motor's resistor pack, which controls fan speed. Failure typically presents as the rear blower working only on the highest speed setting before stopping completely. The motor is mounted in the roofline headliner unit and is labour-intensive to access, making what is otherwise an inexpensive part relatively costly to replace.

    What you would notice

    • Rear blower fan operates only on highest speed setting
    • No airflow from rear ceiling vents despite controls being active
    • Intermittent rear blower operation that becomes progressively worse
    • Grinding or squealing noise from the ceiling unit before the motor fails completely
    • Rear passenger complaints of no heating or cooling even when front climate is working

    Typically $320–$850 to put right.

CommonElectrical $320–$850 to fix

The rear-zone climate blower motor in the Carnival ceiling unit is known to fail due to brush wear in the DC motor and deterioration of the motor's resistor pack, which controls fan speed. Failure typically presents as the rear blower working only on the highest speed setting before stopping completely. The motor is mounted in the roofline headliner unit and is labour-intensive to access, making what is otherwise an inexpensive part relatively costly to replace.

  • No airflow from rear ceiling vents despite controls being active
  • Intermittent rear blower operation that becomes progressively worse
  • Grinding or squealing noise from the ceiling unit before the motor fails completely
  • Rear passenger complaints of no heating or cooling even when front climate is working

What to check

  1. Test the rear climate control through all fan speed settings with both heating and cooling active.
  2. Confirm air flow from the rear ceiling vents changes appropriately at each speed step — a motor that only works on maximum speed or is completely silent indicates resistor or motor failure.

Where to look: Overhead headliner unit — rear passenger zone ceiling, centre of cabin

Ask the seller

  • “Does the rear air conditioning blower work on all fan speed settings, not just high?”
  • “Has the rear blower motor or resistor ever been replaced?”
  • “Do all rear passengers get adequate heating and cooling from the ceiling vents?”

01Lambda V6 Timing Chain Tensioner Rattle on Cold Start

Start the engine cold from overnight.petrol2015–2023Engine
OccasionalEngine $1,800–$5,500 to fix

Can't confirm for this car

The 3.3L Lambda II and 3.5L Lambda III GDI V6 engines use a hydraulic timing chain tensioner that relies on immediate oil pressure at startup to maintain chain tension. On high-mileage examples (typically above 120,000 km), oil pump output or tensioner check-valve function degrades, allowing the chain to momentarily slap the guide rails on cold start before oil pressure builds. Prolonged neglect causes chain guide wear, chain stretch, and ultimately timing deviation that can cause valve-to-piston contact.

Symptoms to notice

  • Metallic rattling from the front of the engine for 2–10 seconds on cold start
  • Rattle that reappears after the vehicle has sat for several hours
  • Check engine light with camshaft position error codes P0011, P0014, P0021, P0024
  • Rough running or misfires if timing has shifted due to chain stretch
  • Engine stall or no-start in severe cases of chain jump

What to check

  1. Start the engine cold from overnight.
  2. Listen for a metallic rattling or clattering sound from the front of the engine in the first 2–5 seconds of running; the noise should clear completely within 5 seconds once oil pressure builds.
  3. Any rattle that persists beyond 5 seconds or is present on a warm restart indicates worn guides or a failing tensioner.

Where to look: Front of engine block — timing chain cover, accessible after front engine cover removal

Parts involved: Timing chain.

Ask the seller

  • “Does the engine make any rattling or clattering sound in the first few seconds after a cold start?”
  • “Has the timing chain, tensioner, or guides ever been inspected or replaced?”
  • “What oil specification and change interval has been used throughout ownership?”

042.2 CRDi injector faults and leaking injector seals

diesel2011–2020Engine
OccasionalEngine $600–$3,500 to fix

Can't confirm for this car

The 2.2 R-series diesel (late VQ and YP Carnival) suffers injector problems: leaking copper injector seat washers that let combustion gases escape (chuffing noise and black tar around the injectors - so-called 'black death'), and failing injectors that cause hard cold starts, black smoke and rough idle. Left alone, a leaking injector can seize into the head, turning a seal job into a head-off repair. Australian owners on ProductReview and Kia forums report injector seal replacements as a known service item on higher-km diesels.

Symptoms to notice

  • Chuffing/ticking noise from the top of the engine
  • Diesel/exhaust smell in the cabin
  • Hard starting when cold
  • Black smoke and rough idle

What to check

With the engine running, open the bonnet and remove the engine cover if easy - listen for a rhythmic chuff and look for black sticky deposits around the injectors. Ask when injectors or seals were last done.

Where to look: Injectors on top of the engine, under the plastic engine cover

Parts involved: Fuel injector.

06R 2.2 CRDi EGR Cooler Failure and Coolant Contamination

Check for oil leaks around valve covers, sump and gaskets.diesel2009–2020Engine
CommonEngine $1,330–$2,660 to fix

Can't confirm for this car

The D4HB 2.2-litre diesel's EGR cooler is prone to internal cracking, allowing coolant to enter the EGR circuit and intake manifold. Symptoms include white smoke at idle, unexplained coolant loss and in severe cases hydrolock. ACCC has records of EGR-related complaints on this engine family. The cooler and EGR valve typically require replacement together; if coolant has entered the combustion chambers a compression test is mandatory before reassembly.

Symptoms to notice

  • Blue or white smoke from exhaust
  • Coolant loss or steam from engine bay
  • Difficult cold start or unstable idle

What to check

  1. Check for oil leaks around valve covers, sump and gaskets.
  2. Inspect coolant condition and level.

Parts involved: EGR valve.

07R2.2 CRDi EGR Valve Carbon Fouling and Failure

Inspect the EGR valve connector and body for carbon seepage.diesel2015–2022Engine
CommonEngine $480–$1,800 to fix

Can't confirm for this car

The 2.2L CRDi exhaust gas recirculation valve operates in a high-soot environment and accumulates carbon deposits on the valve seat and actuator shaft over 80,000–150,000 km. A stuck-open EGR delivers excessive inert gas into the intake, causing rough idle, black smoke, and significant power loss. A stuck-closed valve triggers a check engine light and may cause overheating of the EGR cooler. In worst cases, cooler failure allows coolant to enter the intake manifold.

Symptoms to notice

  • Rough, lumpy idle especially when cold or at low engine load
  • Black smoke from the exhaust under light acceleration
  • Noticeable loss of power, particularly below 2,000 rpm
  • Check engine light with codes P0400, P0401, P0402 (EGR flow fault)
  • White smoke and possible coolant smell if EGR cooler has failed

What to check

  1. Inspect the EGR valve connector and body for carbon seepage.
  2. Check the intake manifold for heavy black soot deposits visible through the throttle body.
  3. On a cold start, watch for excessive black smoke at idle that does not clear within 30 seconds of warm-up.

Where to look: Left side of engine — EGR valve between exhaust manifold and intake, with cooler unit

Parts involved: EGR valve.

Ask the seller

  • “Has the EGR valve ever been cleaned or replaced, and is there a receipt?”
  • “Has the engine ever thrown a check engine light relating to exhaust recirculation codes?”
  • “Does the engine idle smoothly from cold without excessive black smoke?”

01R 2.2 CRDi Brake Vacuum Pump Failure

Inspect pad thickness and rotor condition.diesel2010–2021Brakes
CommonBrakes $980–$1,960 to fix

Can't confirm for this car

The engine-driven vacuum pump that supplies the brake booster on the D4HB diesel can fail due to worn vanes or a failed pump seal, reducing or eliminating power brake assist. Pedal effort increases sharply and stopping distances grow. The fault can be intermittent, making diagnosis difficult. A failed pump also contaminates the engine oil circuit with brake vacuum residue. Replacement of the pump and inspection of related seals is the fix.

Symptoms to notice

  • Longer stopping distances than expected
  • Fault codes or irregular readings when scanned

What to check

  1. Inspect pad thickness and rotor condition.
  2. Check for uneven wear or scoring.
  3. Test pedal feel and stopping distance.

CommonEngine $2,200–$4,500 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 Lambda II 3.8 V6 (VQ38) uses a secondary timing chain on the rear bank that is prone to stretching and guide failure from around 100,000 km. Cold-start rattle that persists beyond warm-up is the primary indicator. Guides can disintegrate and lodge in the oil sump; left unaddressed the chain jumps a tooth causing catastrophic valve damage. Well-documented on Kia Carnival owner forums in Australia and New Zealand.

Symptoms to notice

  • Rattling or ticking noise from rear of engine on cold start
  • Rattle persists for more than 30 seconds after startup
  • Check Engine light with cam timing codes P0016, P0017, P0018, P0019
  • Rough idle or misfires after extended rattle period

What to check

  1. Start cold and listen immediately for chain rattle from the firewall-side of the engine.
  2. Inspect oil for metal debris.
  3. Request full service history and ask if timing chain work has been completed.
  4. If a workshop inspection is possible: Check for cam timing DTCs with an OBD scanner.

Where to look: Rear of the 3.8 V6 engine, secondary chain between exhaust and intake cams on rear bank

Parts involved: Timing chain.

Ask the seller

  • “Has the secondary timing chain or guides been replaced?”
  • “Has the engine ever thrown cam timing fault codes?”
  • “When was the last oil service and what weight oil was used?”

02Rocker cover gasket oil leaks onto coil packs, and head gasket history (3.5/3.8 V6)

Look down the sides of the engine for wet oil trails from the rocker covers.petrol2006–2014Engine
CommonEngine $400–$3,500 to fix

Does not apply

On the VQ Grand Carnival V6 the rocker (tappet) cover gaskets harden with age and leak oil externally and into the spark plug tubes, soaking the coil packs and causing misfires. Earlier Carnivals were also known for head gasket failures, so any overheating history on a VQ deserves suspicion. The gasket job itself is cheap; ruined coil packs and ignored leaks add up, and a head gasket on the V6 is a major repair.

Symptoms to notice

  • Misfire or rough running, especially in the wet
  • Oil around the spark plug wells
  • Oil smell / smoke from the engine bay
  • Coolant loss or white exhaust smoke (head gasket)

What to check

  1. Look down the sides of the engine for wet oil trails from the rocker covers.
  2. Check the coolant reservoir for oil contamination and the oil cap for mayonnaise.
  3. Ask about any overheating events.

01Engine wiring harness recall - crank sensor connection causes stalling (KA4)

Run the VIN through the Kia Australia/NZ recall checker and confirm all outstanding campaigns are closed.2021 onwardElectrical
RareElectrical $0–$1,500 to fix

Does not apply

2023-build KA4 Carnivals were recalled in Australia because an incorrectly manufactured engine wiring harness can give a poor connection at the crankshaft position sensor, causing the engine to stall or lose power without warning - dangerous at speed. A related 2024-build recall covered the main harness chafing on the steering column, which can knock out power steering assistance. Both are free dealer fixes; the danger is buying a car that never went in.

Symptoms to notice

  • Intermittent stalling or loss of power
  • Engine cranks but won't start
  • Check engine light with crank sensor codes
  • Sudden heavy steering (2024 harness issue)

What to check

Run the VIN through the Kia Australia/NZ recall checker and confirm all outstanding campaigns are closed. Any history of unexplained stalling on a 2023-2024 build needs the recall status verified in writing.

Where to look: Engine wiring harness, engine bay and steering column

Parts involved: Steering rack.

Ask the seller

  • “Are there any open recalls on the VIN?”
  • “Has the car ever stalled or lost power steering?”

02Alternator failure and overcharging (VQ Grand Carnival)

With the engine running, measure voltage at the battery: it should sit between about 13.5 and 14.7V.petrol2006–2014Electrical
CommonElectrical $500–$1,200 to fix

Does not apply

VQ Grand Carnival owners in Australia and NZ commonly report alternator failures, including units overcharging above 15 volts, which cooks batteries and can damage electronics. The V6 alternator is buried low in the engine bay and labour makes the job dearer than the part. Combined with the model's appetite for batteries, an unexplained battery warning light or repeatedly dead batteries on a VQ points here first.

Symptoms to notice

  • Battery warning light on or flickering
  • Headlights brightening/dimming with revs
  • Repeated dead or cooked batteries
  • Voltmeter reading over 15V

What to check

With the engine running, measure voltage at the battery: it should sit between about 13.5 and 14.7V. Check the battery's age sticker - a very new battery on an old car can mean a charging problem was being chased.

Where to look: Alternator, low on the front of the V6 engine

Parts involved: Alternator.

Ask the seller

  • “Has the alternator ever been replaced?”
  • “How many batteries has the car been through?”
Fluid leaks1

01Fire-risk recalls: V6 fuel leak and tow-hitch harness module (KA4)

Sniff for fuel with the engine warm.petrol2021 onwardFluid Leaks
RareFluid Leaks $0–$800 to fix

Does not apply

Two separate KA4 fire-risk recalls matter to buyers: about 6000 V6 petrol Carnivals were recalled in Australia (July 2026) for a fuel leak that can lead to a vehicle fire, and 2022-2023 cars fitted with a genuine tow hitch were recalled because water pooling on the tow hitch harness module's circuit board can short and catch fire. Both fixes are free, but a fuel smell or a towbar-equipped car with unknown recall status should be treated seriously.

Symptoms to notice

  • Fuel smell around the engine bay or under the van
  • Trailer lighting faults
  • Melted or burnt smell near the rear bumper (tow module)

What to check

Sniff for fuel with the engine warm. If the car has a factory towbar, check the recall status for the tow hitch harness campaign by VIN. Ask for recall completion paperwork.

Where to look: Fuel system in engine bay; tow hitch wiring module behind rear bumper

Ask the seller

  • “Have the fuel leak and tow hitch recalls been done?”
  • “Has the car ever smelled of petrol?”

Kia Carnival buyer questions

Is the Kia Carnival reliable?

Like any used car, it depends on the specific example and its service history. Across the 17 documented faults for the Kia Carnival, the recurring problem areas are engine, electrical, and fluid leaks. A Kia Carnival 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 Kia Carnival?

We've catalogued 17 known faults for the Kia Carnival, covering engine, electrical, and fluid leaks. All 17 are written out in full on this page, with the symptoms to notice, what to inspect, and typical repair costs for each. Free to read, no account needed.

How much do repairs cost on a Kia Carnival?

Most single repairs on the Kia Carnival fall between $480–$2,660 at NZ independent-workshop rates. Some of the 17 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 Kia Carnival?

Yes. A Kia Carnival 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 $24.90 far less than the cost of missing one of the faults on this page.
