Fiat Coupe MOT Failures
An analysis of 16,256 real DVSA MOT tests on the Fiat Coupe — what fails, how often, and how that compares to every other car on UK roads. Generations covered: 175 (1993–2001).
Where the Fiat Coupe fails its MOT
The single biggest MOT failure point on the Fiat Coupe is structural corrosion — this model is 51 times more likely to fail on this item than the average car on UK roads. That makes it a major concern for anyone buying or owning this model. Across 16,256 MOT tests, 15.18% of all Fiat Coupe tests recorded this as a failure.
Bodywork failures usually mean structural corrosion — not cosmetic rust, but rot that affects the car's structural integrity. Check sills, subframes, and chassis rails carefully, especially on older examples.
Other notable weak points include service brake efficiency below minimum requirement (25x the fleet average), emissions failure (21x the fleet average), braking effort inadequate at a wheel (71x the fleet average), and steering rack wear (22x the fleet average). These ratios compare the Fiat Coupe'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 6 categories: Bodywork, Brakes, Exhaust & Emissions, Steering, Suspension and others. If you're inspecting a Fiat Coupe 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 Fiat Coupe'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 Fiat Coupe specifically, the DVSA data shows the most common failures at this mileage are structural corrosion (51x the average) and parking brake efficiency below minimum requirement (16x). headlight fault (15x) and anti-roll bar links worn (13x) 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 Fiat Coupe specifically, the DVSA data shows the most common failures at this mileage are abs fault (132x the average) and braking effort inadequate at a wheel (71x). service brake efficiency below minimum requirement (25x) and structural corrosion (22x) 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 Fiat Coupe specifically, the DVSA data shows the most common failures at this mileage are braking effort inadequate at a wheel (47x the average) and headlight fault (14x). service brake efficiency below minimum requirement (13x) and subframe bushes or mounts worn (11x) also appear frequently.
The shift from structural corrosion at lower mileages to braking effort inadequate at a wheel at higher mileages is typical — early failures tend to be design or factory-related, while high-mileage failures reflect accumulated mechanical wear. A car that's been well maintained will usually dodge the worst of both.
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 Fiat Coupe specialists and owners flag most frequently, drawn from manufacturer technical bulletins, workshop data, and verified owner reports.
Structural corrosion around suspension mounting points Dangerous
MOT data shows this model fails at 131.8 times the fleet average for load-bearing structure failure within 30cm of suspension mounting points. Affects 175; typical independent garage repair cost is £800–£2,000.
Brake system deterioration Dangerous
The brake calipers seize due to corrosion in the piston bores and guide pins, causing uneven braking force distribution. Affects 175; typical independent garage repair cost is £600–£1,200.
Emissions system failure Major
The catalytic converters deteriorate due to age and contamination from oil consumption common on these engines. Affects 175; typical independent garage repair cost is £400–£800.
General body corrosion Major
0 times average for general structural corrosion. Affects 175; typical independent garage repair cost is £500–£1,500.

What to check before buying a Fiat Coupe
Based on the MOT failure data and known issues above, here's what to prioritise when inspecting a Fiat Coupe:
Bodywork — check for structural corrosion. Brakes — check for service brake efficiency below minimum requirement, braking effort inadequate at a wheel. Exhaust & Emissions — check for emissions failure.
Beyond the MOT items, ask specifically about structural corrosion around suspension mounting points and brake system deterioration. 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.

Fiat Coupe MOT FAQs
What are the most common MOT failures on a Fiat Coupe?
Based on 16,256 DVSA MOT tests, the most common failure is structural corrosion — at 51x the national fleet average. Other frequent failures include service brake efficiency below minimum requirement and emissions failure.
Is the Fiat Coupe reliable based on MOT data?
The Fiat Coupe has 15 MOT failure categories above the fleet average. Specialists also flag structural corrosion around suspension mounting points as a concern. A pre-purchase inspection and service history check are recommended.
What MOT failures should I expect at high mileage?
Above 100,000 miles, the Fiat Coupe most commonly fails on braking effort inadequate at a wheel and headlight fault. Under 60,000 miles, the main issues are structural corrosion and parking brake efficiency below minimum requirement.
