Symptoms

Orange steering wheel warning light
Suddenly heavy steering, especially at low speed
Intermittent loss of assistance
Clunking or clicking from steering column
C1288 or U3000 fault codes

Root Cause

The EPS motor and control module are mounted on the steering column. The motor brushes wear out, the torque sensor fails, or the module develops faults. Heat and vibration accelerate wear on the column-mounted electronics.

How To Fix

Read fault codes with a Forscan-compatible reader — confirms EPS fault vs. sensor
Remanufactured steering columns available from £150-250 (exchange)
Programming required after replacement — many independent garages can do this
Full replacement at Ford dealer: £600-900. Independent: £300-500

Other Faults on This Variant

Timing Chain Stretch and Tensioner Failure

Critical

2012-201540,000–100,000 miles£600–£1200

Pre-2016 Ford 1.0 EcoBoost engines suffer from premature timing chain stretch. The plastic tensioner can fail, causing catastrophic engine damage with little warning.

Coolant Loss from Cylinder Head

Severe

2012-201860,000–120,000 miles£500–£900

The 1.0 EcoBoost has an integrated exhaust manifold cast into the cylinder head. This design causes head gasket stress and coolant loss, sometimes causing overheating.

Thermostat Failure and Overheating Risk

Moderate

2012-201850,000–100,000 miles£80–£180

The plastic thermostat housing on the 1.0 EcoBoost is prone to cracking. A stuck-open thermostat causes the engine to run cold and burn more fuel; a stuck-closed thermostat causes rapid overheating.
