Credov's researched list of the 3 faults the Kia Forte is known for (2013–2018), 2 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: Start the engine from cold and listen for a knock, then check whether it fades or stays as it warms.
Why it matters: This engine family can progress from a noise that many sellers dismiss as normal into a full bearing failure, each costing roughly a replacement engine.
What to look for: Check the dipstick and ask when it was last topped up, and listen on cold start for knocking.
Why it matters: This is a known manufacturing defect that can cause a loss of power and, in the worst cases, a fire risk, and the usual fix seen in other markets has been engine replacement.
What to look for: Lift the boot floor and spare wheel and check for standing water, rust or mould, then test every rear light.
Why it matters: A leak like this is often found only after several dealer visits, and a wet spare-wheel well left unchecked leads to rust, mould and intermittent rear light failures that can affect safety and WoF.
