We've identified 4 known issues that can affect the 2014–2018 DS Automobiles DS 4. 2 of these are serious faults that could be expensive to repair.
The timing belt runs in oil and can degrade, shedding debris that blocks the oil pickup and can lead to vacuum pump failure (affecting braking assistance) and total engine failure.
The turbo petrol DS 4 shares the same Prince-engine weak points as its Peugeot and Mini relatives, with timing-chain noise and carbon build-up the biggest ownership risks.
The semi-automated gearbox is acceptable when healthy but quickly feels broken if the clutch or actuator is tired, leading to jerky shifts and expensive catch-up work.
The DS 4’s firm ride and big wheels can punish the front suspension, so top mounts, links and bushes often become noisy on UK cars.
