Known faults on the 2018 Ford Focus petrol
Reported by owners, mechanics and buying guides for this model and age. Check which engine the car has, as some apply to one engine only.
- 1.0 petrol (EcoBoost and non-turbo)
Timing belt that runs in oil (1.0 EcoBoost)
Ford’s 1.0 three-cylinder petrol uses a timing belt that runs in the engine oil on most cars. If oil changes are late or the wrong oil is used, the belt breaks down and sheds rubber that blocks the oil supply, which can wreck the engine. Some later cars have a timing chain instead: a Ford dealer can tell you from the VIN. Ford’s change interval is 10 years or 150,000 miles, and the belt isn’t covered by warranty.
At the viewing: Ask for a full service history with the right oil, and when the belt was changed. An oil-pressure warning light, a rattle or a rough idle are warning signs.

- Automatic versions only
PowerShift automatic gearbox
Expert buying guides suggest avoiding the PowerShift automatic on this Focus. Early versions especially were troublesome.
At the viewing: If it’s an automatic, ask for proof of gearbox fluid changes and test it in slow traffic for judder or hesitation.
Broken front coil springs
Front springs can snap. You may hear a clonk when turning the wheel.
At the viewing: With the car stopped, turn the steering from lock to lock and listen for a clonk or twang. Springs should be replaced in pairs.
If it needs doing: Coil springs (pair), about £175–£400. ClickMechanic
Rattle from the flywheel
A rattle as you switch the engine off can mean the dual-mass flywheel is failing, which is a big job alongside the clutch.
At the viewing: Switch the engine off and listen for a rattle. Check the clutch doesn’t bite very high.
If it needs doing: Clutch and dual-mass flywheel, about £650–£1,200. ClickMechanic
