Other Faults on This Variant
Powershift Dual Clutch Gearbox Failure
CriticalThe 6-speed Powershift (MPS6/6DCT450) automatic gearbox is notoriously fragile. Internal plastic parts shatter, clogging the transmission filter.
Steering Rack Motor Failure (EPS)
CriticalThe Electronic Power Steering rack on the Mk3 Focus suffers from water ingress, causing the motor to short out.
Air Conditioning Condenser Leak (Stone Damage)
MinorThe air conditioning condenser is mounted at the very front of the cooling pack, making it highly susceptible to stone damage from the road, leading to refrigerant loss.
