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.
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.
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.
