Seat Exeo MOT Failures
An analysis of 76,849 real DVSA MOT tests on the Seat Exeo — what fails, how often, and how that compares to every other car on UK roads. Generations covered: 3R (2009–2013).
Where the Seat Exeo fails its MOT
The single biggest MOT failure point on the Seat Exeo is brake hoses perished or damaged — this model is 23 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 76,849 MOT tests, 5.65% of all Seat Exeo tests recorded this as a failure.
Brake failures on the MOT range from worn pads and discs (routine maintenance) to corroded brake lines and seized calipers (more serious). Check for any pulling under braking and listen for grinding.
Other notable weak points include track rod ends worn (13x the fleet average), any part of the noise suppression system insecure (11x the fleet average), seat mounting fault (11x the fleet average), and body panel or body component (7.0x the fleet average). These ratios compare the Seat Exeo'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 7 categories: Brakes, Steering, Exhaust & Emissions, Bodywork, Lights & Electrics and others. If you're inspecting a Seat Exeo 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 Seat Exeo'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 Seat Exeo specifically, the DVSA data shows the most common failures at this mileage are brake hoses perished or damaged (23x the average) and track rod ends worn (13x). coil springs broken (5.7x) and coil springs broken 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 Seat Exeo specifically, the DVSA data shows the most common failures at this mileage are brake hoses perished or damaged (16x the average) and any part of the noise suppression system insecure (11x). light unit fault (6.8x) and tyres on the same axle or on twin wheels are di... (5.8x) 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 Seat Exeo specifically, the DVSA data shows the most common failures at this mileage are seat mounting fault (11x the average) and brake hoses perished or damaged (10x). body panel or body component (7.0x) and any part of the noise suppression system insecure (6.1x) also appear frequently.
The shift from brake hoses perished or damaged at lower mileages to seat mounting fault 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 Seat Exeo specialists and owners flag most frequently, drawn from manufacturer technical bulletins, workshop data, and verified owner reports.
Flexible brake hose deterioration (3R) Dangerous
The flexible brake hoses on the Exeo deteriorate at an exceptionally high rate compared to other vehicles, with the 2.0 TDI showing brake hose failures at over 23 times the national fleet average. Affects 3R; typical independent garage repair cost is £120–£200.
Steering rack gaiter deterioration (3R) Major
The steering rack gaiters (rubber dust covers) on the Exeo fail at 12.8 times the national fleet average, becoming damaged, deteriorated, or missing entirely. Affects 3R; typical independent garage repair cost is £80–£150.
Suspension component wear (3R) Major
The Exeo shows suspension pin, bush and joint wear at 4.3 times the national fleet average, with failures becoming more common above 60,000 miles. Affects 3R; typical independent garage repair cost is £200–£400.
Brake disc warping (3R) Major
This occurs notably early in the vehicle's life, with failures seen from 40,000 miles onwards. Affects 3R; typical independent garage repair cost is £150–£300.

What to check before buying a Seat Exeo
Based on the MOT failure data and known issues above, here's what to prioritise when inspecting a Seat Exeo:
Brakes — check for brake hoses perished or damaged. Steering — check for track rod ends worn. Exhaust & Emissions — check for any part of the noise suppression system insecure. Bodywork — check for seat mounting fault, body panel or body component.
Beyond the MOT items, ask specifically about flexible brake hose deterioration and steering rack gaiter deterioration. These won't show up on a standard MOT but can be expensive to fix — repairs start from £120. 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.
