Known Kia Carnival faults
Every fault below is documented specifically for this model — researched and verified before it’s published.
01Lambda V6 Timing Chain Tensioner Rattle on Cold Start
CriticalOccasionalEngine $1,800–$5,500 to fix
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
Start the engine cold from overnight. 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. 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
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?”
02Alternator failure and overcharging (VQ Grand Carnival)
MinorCommonElectrical $500–$1,200 to fix
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
Ask the seller
“Has the alternator ever been replaced?”
“How many batteries has the car been through?”

Like any used car, it depends on the specific example and its service history. Across the 19 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 19 known faults for the Kia Carnival, covering engine, electrical, 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 Kia Carnival?
+
Most single repairs on the Kia Carnival fall between $480–$2,660 at NZ independent-workshop rates. Some of the 19 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 $17.90 far less than the cost of missing one of the faults on this page.
