Known faults
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.
- Timing belt that runs in oil (1.0 EcoBoost)1.0 EcoBoost petrol
The 1.0 EcoBoost’s timing belt sits in the engine oil. Missed or wrong-spec oil changes can make it break down and block the oil pickup, which can wreck the engine.
At the viewing: Ask for a full service history with regular oil changes, and whether the timing belt has been changed when due.
- PowerShift automatic gearboxAutomatic versions only
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.
- 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.
