Alfa Romeo Gt MOT Failures
An analysis of 40,701 real DVSA MOT tests on the Alfa Romeo Gt — what fails, how often, and how that compares to every other car on UK roads. Generations covered: 937 (2003–2010).
Where the Alfa Romeo Gt fails its MOT
The single biggest MOT failure point on the Alfa Romeo Gt is structural corrosion — this model is 36 times more likely to fail on this item than the average car on UK roads. That makes it a significant weak point for anyone buying or owning this model. Across 40,701 MOT tests, 4.53% of all Alfa Romeo Gt 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 seat mounting fault (15x the fleet average), emissions failure (48x the fleet average), abs fault (29x the fleet average), and headlight fault (19x the fleet average). These ratios compare the Alfa Romeo Gt'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, Seatbelts & Airbags, Exhaust & Emissions, Suspension, Lights & Electrics and others. If you're inspecting a Alfa Romeo Gt 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 Alfa Romeo Gt'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 Alfa Romeo Gt specifically, the DVSA data shows the most common failures at this mileage are exhaust system damage (10x the average) and abs fault (9.9x). subframe bushes or mounts worn (6.3x) and subframe bushes or mounts worn 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 Alfa Romeo Gt specifically, the DVSA data shows the most common failures at this mileage are emissions failure (48x the average) and anti-roll bar links worn (30x). cable damaged or knotted (21x) and headlight fault (19x) 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 Alfa Romeo Gt specifically, the DVSA data shows the most common failures at this mileage are structural corrosion (36x the average) and main load-bearing structural member fractured o... (31x). abs fault (29x) and electrical wiring fault (16x) also appear frequently.
The shift from exhaust system damage at lower mileages to structural corrosion 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 Alfa Romeo Gt specialists and owners flag most frequently, drawn from manufacturer technical bulletins, workshop data, and verified owner reports.
Structural corrosion around suspension mounting points Dangerous
The GT suffers from severe structural corrosion around suspension mounting points and subframe attachment areas, particularly affecting the rear suspension mounting points and front subframe mounting areas. Affects All; typical independent garage repair cost is £800–£1,500.
DPF blockage and emissions failure (1.9 JTD) Major
The 1.9 JTD diesel engine suffers from diesel particulate filter (DPF) blockage, with MOT data showing smoke opacity failures at The DPF system requires regular high-speed driving to burn off accumulated soot. Affects All; typical independent garage repair cost is £200–£400.
Suspension component corrosion Major
GT models suffer from accelerated corrosion of suspension components, with MOT data showing failures at 842.4x the fleet average. Affects All; typical independent garage repair cost is £150–£300.
General body corrosion Major
The GT suffers from widespread body corrosion issues typical of Italian cars from this era. Affects All; typical independent garage repair cost is £300–£800.

What to check before buying a Alfa Romeo Gt
Based on the MOT failure data and known issues above, here's what to prioritise when inspecting a Alfa Romeo Gt:
Bodywork — check for structural corrosion, exhaust system damage. Seatbelts & Airbags — check for seat mounting fault. Exhaust & Emissions — check for emissions failure. Suspension — check for abs fault, anti-roll bar links worn.
Beyond the MOT items, ask specifically about structural corrosion around suspension mounting points and dpf blockage and emissions failure. 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.
