What goes wrong, what it costs, and what to check before you buy a used Ford Cougar.
The Ford Cougar occupies a niche position on the UK market.
We track 5 known issues across the Ford Cougar range, including 2 rated as safety-critical. Knowing which variants and configurations to approach with caution can save you from expensive surprises after purchase.

MK1 (1998–2002) — Engine options included the 2.5L V6 Duratec, 2.5L V6 ST200. Our database flags 5 known issues on this generation, 2 of which are rated as safety-critical. The most significant concern is Structural corrosion at suspension mounting points (£800–£2,000 to address).
The Ford Cougar suffers from severe structural corrosion around suspension mounting points, particularly the rear subframe and front suspension turrets. The unibody construction uses relatively thin steel that corrodes from inside out, often appearing sound externally while being structurally compromised underneath. MOT data shows this model fails at over 15x the national average for load-bearing structure defects. This is a safety-critical failure that can cause suspension collapse.
Structural failure can cause sudden suspension collapse, loss of vehicle control, and serious accident. The car becomes immediately dangerous to drive and may not be economically repairable. Structural welding costs typically exceed the vehicle's value on cars over 15 years old.
Inspect the wheel arches, sills, jacking points and door bottoms carefully. Press gently on sills to check for soft spots. Look underneath for corrosion on structural components. Check the MOT history for corrosion-related advisories or failures.
Ford Cougar brake lines suffer from severe corrosion, particularly the steel pipes running along the rear axle and the flexible hoses at the front wheels. The brake lines are inadequately protected from road salt and moisture, leading to perforation and brake fluid loss. MOT data shows failure rates over 11x the national average for brake pipe corrosion. This represents a critical safety hazard as brake failure can occur without warning.
Brake line failure causes sudden loss of braking ability and immediate danger of serious accident. The car must not be driven with suspected brake line damage. Complete brake system renovation may be required if corrosion is widespread, often exceeding the vehicle's value.
Check brake disc condition for lipping or scoring. Test braking at moderate speed for pulling to one side or vibration through the steering wheel. Review MOT advisories for brake-related items.
Ford Cougar suspension components, particularly the lower control arms and anti-roll bar links, suffer from severe corrosion that leads to excessive wear and failure. The car uses steel suspension components with inadequate corrosion protection for UK conditions. MOT data shows failure rates over 24x the national average for suspension component damage. Failed components cause handling deterioration and MOT failure.
Corroded suspension components cause poor handling, increased tyre wear, and MOT failure. Complete failure of a ball joint or control arm can cause loss of control. Replacement typically requires multiple components due to corrosion affecting adjacent parts simultaneously.
Listen for knocking, clunking or rattling over bumps during the test drive. Inspect the underside for corroded or cracked suspension components. Check the MOT history for suspension-related advisories, which often predict future failures.
The Ford Cougar hydraulic power steering system suffers from high-pressure hose failure and pump wear. The system operates at high pressure and the rubber hoses deteriorate with age, causing sudden loss of power assistance. MOT data shows this model fails at over 72x the national average for power steering defects. Complete failure makes the car very difficult to steer, especially at parking speeds.
Complete power steering failure makes the car extremely difficult to steer, particularly dangerous in parking situations or emergency manoeuvres. High-pressure fluid leaks can cause environmental damage and MOT failure. Pump failure often damages other system components, increasing repair costs.
During the test drive, check the steering for excessive play, vibration or pulling to one side. Listen for groaning or whining when turning the wheel at low speed. Power steering fluid level and condition should be checked on hydraulic systems.
Ford Cougar wheel bearings, particularly the front units, develop excessive play and wear at relatively low mileages. The sealed bearing units are vulnerable to water ingress and road salt contamination, leading to premature failure. MOT data shows this model fails at over 9x the national average for wheel bearing defects. Failed bearings cause noise, vibration, and can lead to wheel detachment in extreme cases.
Worn wheel bearings cause increasing noise and vibration, leading to driver fatigue and further damage to suspension components. Complete bearing failure can cause wheel wobble or detachment, creating serious accident risk. Early replacement prevents damage to the hub assembly.
Listen for knocking, clunking or rattling over bumps during the test drive. Inspect the underside for corroded or cracked suspension components. Check the MOT history for suspension-related advisories, which often predict future failures.

Based on 4k real DVSA MOT tests, the Ford Cougar fails more often than average on several items. The biggest outlier is suspension ball joints worn at 123x the fleet average, followed by subframe bushes or mounts worn (118x).
When viewing a specific car, check its MOT history for recurring advisories in these categories. See the full Ford Cougar MOT failure breakdown for data at every mileage point.
Routine servicing (oil and filter change every 10k miles) typically costs £80–£120 at an independent garage.

The Ford Cougar has some well-documented weak points, including 2 safety-critical issues that demand careful checking. The right example, properly maintained, can still be a sound purchase — but cutting corners on the pre-purchase inspection is not advisable.
