Ford Cougar MOT Failures
An analysis of 9,156 real DVSA MOT tests on the Ford Cougar — what fails, how often, and how that compares to every other car on UK roads. Generations covered: MK1 (1998–2002).
Where the Ford Cougar fails its MOT
The single biggest MOT failure point on the Ford Cougar is subframe bushes or mounts worn — this model is 118 times more likely to fail on this item than the average car on UK roads. That makes it an extreme outlier for anyone buying or owning this model. Across 9,156 MOT tests, 23.92% of all Ford Cougar tests recorded this as a failure.
Suspension failures typically mean worn bushes, drop links, or dampers. These affect handling and tyre wear. Budget £150–£400 per corner at an independent garage for full suspension overhaul.
Other notable weak points include structural corrosion (50x the fleet average), power steering fault (94x the fleet average), abs fault (19x the fleet average), and seat mounting fault (15x the fleet average). These ratios compare the Ford Cougar's failure rate on each item against the national average for all cars tested — a ratio of 10x means this model fails ten times more often than a typical car.
The failures span 5 categories: Suspension, Bodywork, Steering, Seatbelts & Airbags, Brakes. If you're inspecting a Ford Cougar before purchase, these are the areas to focus on — and if any have been flagged as advisories on a previous MOT, they're likely to become failures in the near future.
How failures change with mileage
The Ford Cougar's weak points shift as the car covers more miles. Understanding these patterns helps you know what to expect — and what to budget for — at each stage of ownership.
Under 60,000 miles
At this mileage, most failures are either design-related or caused by age rather than wear. Components like bushes and drop links may not have been replaced yet, and original-fit parts can deteriorate even on low-mileage cars that spend a lot of time sitting.
For the Ford Cougar specifically, the DVSA data shows the most common failures at this mileage are subframe bushes or mounts worn (118x the average) and power steering fault (94x). headlight fault (21x) and parking brake efficiency below minimum requirement (16x) also appear frequently.
60,000 to 100,000 miles
This is where routine wear items start to show up. Brake components, tyres, and exhaust parts have done serious work by this point. Cars that have been well serviced will show fewer of these failures — this mileage band is where good maintenance really separates the well-kept from the neglected.
For the Ford Cougar specifically, the DVSA data shows the most common failures at this mileage are suspension ball joints worn (123x the average) and power steering fault (72x). structural corrosion (50x) and subframe bushes or mounts worn (27x) also appear frequently.
Over 100,000 miles
High-mileage cars accumulate failures across multiple systems. The key question isn't whether things will need doing — they will — but whether the car has been maintained well enough to keep on top of them. Look for a consistent service history and recent MOT passes with minimal advisories.
For the Ford Cougar specifically, the DVSA data shows the most common failures at this mileage are subframe bushes or mounts worn (16x the average) and structural corrosion (14x). seat mounting fault (12x) and abs fault (7.8x) also appear frequently.
Known issues beyond the MOT
An MOT only tests roadworthiness at a single point in time — it won't catch developing faults, intermittent problems, or issues that haven't yet reached the failure threshold. These are the issues that Ford Cougar specialists and owners flag most frequently, drawn from manufacturer technical bulletins, workshop data, and verified owner reports.
Structural corrosion at suspension mounting points (MK1) Dangerous
The Ford Cougar suffers from severe structural corrosion around suspension mounting points, particularly the rear subframe and front suspension turrets. Affects MK1; typical independent garage repair cost is £800–£2,000.
Brake line corrosion (MK1) Dangerous
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. Affects MK1; typical independent garage repair cost is £200–£600.
Suspension component corrosion (MK1) Major
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. Affects MK1; typical independent garage repair cost is £400–£800.
Power steering system failure (MK1) Major
The Ford Cougar hydraulic power steering system suffers from high-pressure hose failure and pump wear. Affects MK1; typical independent garage repair cost is £300–£600.

What to check before buying a Ford Cougar
Based on the MOT failure data and known issues above, here's what to prioritise when inspecting a Ford Cougar:
Suspension — check for subframe bushes or mounts worn, abs fault, anti-roll bar links worn. Bodywork — check for structural corrosion, vehicle structure corroded to the extent that t.... Steering — check for power steering fault.
Beyond the MOT items, ask specifically about structural corrosion at suspension mounting points and brake line corrosion. These won't show up on a standard MOT but can be expensive to fix — repairs start from £800. A specialist pre-purchase inspection is worth the investment on this model.
Always check the car's full MOT history for patterns — recurring advisories often become failures within 12 months. And verify the service history to confirm maintenance has been kept up to schedule. Enter any reg into our free car check to see the complete picture.
