Credov's researched list of the 5 faults the Kia Carnival is known for (2014–2020), 4 of them serious or costly. Each one says what to look for when you check the car, so you can spot it before you buy. Not every car has these faults: they are the ones worth checking on this model.
What to look for: Open and close both sliding doors several times by handle and remote, checking each latches fully.
Why it matters: A sliding door that opens or fails to latch while the vehicle is moving is a safety risk to anyone near the opening, not just an annoyance.
What to look for: Open the bonnet and check the secondary safety catch is not rusted, then confirm the closed bonnet will not lift.
Why it matters: A bonnet that can fly open while driving blocks the driver's view of the road ahead without warning, which is a serious safety risk, not just a cosmetic latch fault.
What to look for: Check the oil level on arrival, and listen for a knock from the bottom end when warm.
Why it matters: Oil consumption on this engine is often silent until the bearings have already been starved, and the usual outcome is a seized engine needing full replacement.
What to look for: Operate both power sliding doors several times by handle, key fob and button, checking each latches fully.
Why it matters: A power sliding door that jams partway, or will not latch, is both an inconvenience and a safety risk for anyone near the opening, and replacement motors and mechanisms are expensive.
What to look for: On a white car, look along the bonnet front edge, roof and tailgate under the rear glass for bubbling or flaking paint.
Why it matters: Once it starts, the paint keeps lifting and a proper fix means respraying the affected panels, which is a cosmetic cost a buyer should budget for rather than be surprised by.
