Top issues to watch for
The most serious Ford Fusion problems ranked by severity. We track 5 known issues — here are the ones you need to know about first.
Dangerous
Brake pipe corrosion and failure
The Fusion shows extremely high brake pipe failure rates, with MOT data indicating failures at 26 times the national fleet average. The brake pipes are prone to corrosion, particularly where they run under the vehicle and near suspension mounting points. Both the steel pipes and their connections can fail, leading to brake fluid loss and potential brake system failure. This affects all engine variants and becomes increasingly likely with age.
What happens if ignoredBrake pipe failure results in immediate loss of brake fluid and potential complete brake failure, creating an extreme safety hazard. The car should not be driven if brake pipe damage is suspected. Repair typically requires replacement of corroded pipes and a complete brake system flush and bleed.

Major
Power steering fluid loss and pump failure
The Fusion suffers from widespread power steering system failures affecting the hydraulic pump, fluid reservoir, and connecting pipes. MOT data shows this model fails power steering checks at 49.8 times the national fleet average, with both low fluid levels and damaged pipes being persistent issues. The power steering pump can fail internally, causing fluid contamination and complete loss of assistance. This is compounded by poor pipe routing that leads to corrosion and damage over the vehicle's lifespan.
What happens if ignoredComplete power steering failure makes the car extremely difficult to steer, particularly at parking speeds, creating a significant safety risk. A failed power steering pump typically requires replacement along with a full system flush. If pipes are severely corroded, multiple components may need replacement simultaneously.

Major
Diesel emissions system failure (1.4 TDCi)
The issues stem from DPF (Diesel Particulate Filter) blockage, EGR valve carbon build-up, and fuel system contamination. Short urban journeys prevent the DPF from reaching the temperatures needed for regeneration, causing progressive blockage and excessive smoke production.
What happens if ignoredBlocked DPF systems cause the engine to enter 'limp mode' with severely reduced power and potential engine damage from fuel contamination. DPF replacement or professional cleaning is expensive, and the underlying issues often recur without changes to driving patterns. The car may fail MOT emissions tests repeatedly.

Throttle body failure and sticking
NHTSA data shows 537 complaints about throttle body failures on the Fusion, with symptoms including sudden loss of power, rough idling, and unintended acceleration events. The electronic throttle body can stick or fail due to carbon build-up on the throttle plate or internal motor failure. This affects petrol engines and can cause dangerous driving situations when the throttle becomes unresponsive or sticks open.
What happens if ignoredThrottle body failure can cause sudden loss of power while driving, creating a dangerous situation. Sticking throttles can cause unintended acceleration or inability to control engine speed. The throttle body typically requires replacement as cleaning is often only temporarily effective.
