Build my inspection planFrequently asked questions
Is the Kia Carnival reliable?
Yes — it's a solid family MPV; focus checks on the power doors and electronics.
Does the Carnival have door problems?
Power sliding-door faults are the most common complaint; test them fully.
What should I check on a used Carnival?
Power doors, screens, transmission and oil use.
Does the 3.5L V6 engine use a timing belt or a timing chain?
The 3.5-litre V6 petrol engine fitted to this generation of Carnival utilises a timing chain rather than a rubber timing belt. Under normal conditions, the chain is designed to last the lifetime of the vehicle and requires no scheduled replacement, provided the engine receives regular oil and filter changes.
What is the maximum towing capacity of the 2022-2024 Carnival?
When fitted with a braked trailer and the official Kia towing package, the Carnival can tow up to 1,587 kg. Dealers must ensure any fitted tow bar wiring harness has had the manufacturer recall carried out, as early genuine modules suffered from moisture ingress and short circuits.
Why does the battery drain quickly when parked on the forecourt?
The Carnival features multiple connected modules, including the telematics system and smart key proximity sensors, which can cause a parasitic draw. If the vehicle is left unlocked on the forecourt or the keys are stored too close to the cabin, the systems remain awake, flattening the 12v battery within days.
