Suzuki Swift MOT Failures
An analysis of 156,754 real DVSA MOT tests on the Suzuki Swift — what fails, how often, and how that compares to every other car on UK roads. Generations covered: EA11R (1984–2003), RS413 (2004–2010), FZ (2010–2017), AZ (2017–2024).
Where the Suzuki Swift fails its MOT
The single biggest MOT failure point on the Suzuki Swift is seat mounting fault — this model is 92 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 156,754 MOT tests, 7.79% of all Suzuki Swift tests recorded this as a failure.
Other notable weak points include abs fault (93x the fleet average), braking effort inadequate at a wheel (280x the fleet average), light unit fault (275x the fleet average), and structural corrosion (103x the fleet average). These ratios compare the Suzuki Swift'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: Seatbelts & Airbags, Suspension, Brakes, Lights & Electrics, Bodywork and others. If you're inspecting a Suzuki Swift 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 Suzuki Swift'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 Suzuki Swift specifically, the DVSA data shows the most common failures at this mileage are braking effort inadequate at a wheel (280x the average) and light unit fault (275x). power steering fault (101x) and service brake efficiency below minimum requirement (81x) 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 Suzuki Swift specifically, the DVSA data shows the most common failures at this mileage are braking effort inadequate at a wheel (59x the average) and emissions failure (57x). light unit fault (46x) and abs fault (44x) 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 Suzuki Swift specifically, the DVSA data shows the most common failures at this mileage are emissions failure (21x the average) and suspension component missing, (20x). obstruction within the driver's field of view t... (20x) and suspension component damaged or corroded (17x) also appear frequently.
The shift from braking effort inadequate at a wheel at lower mileages to emissions failure 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 Suzuki Swift specialists and owners flag most frequently, drawn from manufacturer technical bulletins, workshop data, and verified owner reports.
Structural corrosion reducing chassis rigidity Dangerous
The Swift suffers from severe structural corrosion that affects the main chassis rails and body shell to the extent that structural rigidity is compromised. Affects EA11R, RS413, FZ; typical independent garage repair cost is £1,500–£4,000.
Suspension mounting point corrosion Dangerous
The load-bearing structure within 30cm of suspension component mounting points suffers from severe corrosion on the Swift, with MOT failure rates up to 65 times higher than the fleet average. Affects EA11R, RS413, FZ; typical independent garage repair cost is £800–£2,500.
Brake pipe corrosion Dangerous
Brake pipes on the Swift suffer from corrosion at a rate 26 times higher than the fleet average, with over 204,000 recorded MOT failures. Affects EA11R, RS413, FZ, AZ; typical independent garage repair cost is £200–£600.
Brake imbalance across axles Major
The Swift exhibits brake imbalance across axles at a rate 65 times higher than the national fleet average, where braking effort from one wheel is less than 70% of the maximum effort from the other wheel on the same axle. Affects EA11R, RS413, FZ, AZ; typical independent garage repair cost is £300–£800.

What to check before buying a Suzuki Swift
Based on the MOT failure data and known issues above, here's what to prioritise when inspecting a Suzuki Swift:
Seatbelts & Airbags — check for seat mounting fault. Suspension — check for abs fault, suspension pin, bush, joint or bearing worn, suspension component damaged or corroded. Brakes — check for braking effort inadequate at a wheel. Lights & Electrics — check for light unit fault.
Beyond the MOT items, ask specifically about structural corrosion reducing chassis rigidity and suspension mounting point corrosion. These won't show up on a standard MOT but can be expensive to fix — repairs start from £1,500. 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.

Suzuki Swift MOT FAQs
What are the most common MOT failures on a Suzuki Swift?
Based on 156,754 DVSA MOT tests, the most common failure is seat mounting fault — at 92x the national fleet average. Other frequent failures include abs fault and braking effort inadequate at a wheel.
Is the Suzuki Swift reliable based on MOT data?
The Suzuki Swift has 26 MOT failure categories above the fleet average. Specialists also flag structural corrosion reducing chassis rigidity 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 Suzuki Swift most commonly fails on emissions failure and suspension component missing,. Under 60,000 miles, the main issues are braking effort inadequate at a wheel and light unit fault.
