Top issues to watch for

The most serious Ford Cougar problems ranked by severity. We track 5 known issues — here are the ones you need to know about first.

Dangerous
Structural corrosion at suspension mounting points (MK1)
MK11998–200260k–150k miles
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.
What happens if ignoredStructural 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.

Dangerous
Brake line corrosion (MK1)
MK11998–200240k–150k miles
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.
What happens if ignoredBrake 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.

Major
Suspension component corrosion (MK1)
MK11998–200240k–150k miles
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.
What happens if ignoredCorroded 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.

Major
Power steering system failure (MK1)
MK11998–200260k–120k miles
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.
What happens if ignoredComplete 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.
