Fiat Sedici MOT Failures
An analysis of 30,893 real DVSA MOT tests on the Fiat Sedici — what fails, how often, and how that compares to every other car on UK roads. Generations covered: GEN1 (2006–2014).
Where the Fiat Sedici fails its MOT
The single biggest MOT failure point on the Fiat Sedici is brake hoses perished or damaged — this model is 50 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 30,893 MOT tests, 25.51% of all Fiat Sedici 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 suspension component damaged or corroded (14x the fleet average), fluid leak (8.6x the fleet average), emissions failure (7.8x the fleet average), and brake pipes corroded (10x the fleet average). These ratios compare the Fiat Sedici'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 4 categories: Brakes, Suspension, Exhaust & Emissions, Bodywork. If you're inspecting a Fiat Sedici 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 Sedici'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 Sedici specifically, the DVSA data shows the most common failures at this mileage are brake hoses perished or damaged (50x the average) and subframe bushes or mounts worn (31x). abs fault (19x) and brake pipes corroded (10x) 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 Sedici specifically, the DVSA data shows the most common failures at this mileage are brake hoses perished or damaged (8.6x the average) and electrical wiring fault (8.6x). fluid leak (7.9x) and vehicle structure corroded to the extent that t... (7.8x) 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 Fiat Sedici specifically, the DVSA data shows the most common failures at this mileage are transmission joint, belt or chain worn (48x the average) and suspension component damaged or corroded (11x). structural corrosion (10x) and fluid leak (8.4x) also appear frequently.
The shift from brake hoses perished or damaged at lower mileages to transmission joint, belt or chain worn 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 Sedici specialists and owners flag most frequently, drawn from manufacturer technical bulletins, workshop data, and verified owner reports.
Structural corrosion reducing rigidity Dangerous
The Sedici's bodyshell suffers from significant structural corrosion that compromises the rigidity of the main assembly. Affects GEN1; typical independent garage repair cost is £500–£2,000.
Brake hose ferrule corrosion Dangerous
The brake hose ferrules (the crimped metal connections where flexible hoses meet rigid brake pipes) suffer from excessive corrosion on the Sedici. Affects GEN1; typical independent garage repair cost is £150–£300.
Brake pipe corrosion Dangerous
The rigid brake pipes on the Sedici are highly susceptible to corrosion damage. Affects GEN1; typical independent garage repair cost is £200–£500.
Suspension component corrosion damage Major
Suspension components on the Sedici suffer from excessive corrosion damage, particularly affecting control arms, anti-roll bar links, and mounting hardware. Affects GEN1; typical independent garage repair cost is £300–£800.

What to check before buying a Fiat Sedici
Based on the MOT failure data and known issues above, here's what to prioritise when inspecting a Fiat Sedici:
Brakes — check for brake hoses perished or damaged, brake pipes corroded, parking brake inefficient. Suspension — check for suspension component damaged or corroded, subframe bushes or mounts worn. Exhaust & Emissions — check for fluid leak, emissions failure.
Beyond the MOT items, ask specifically about structural corrosion reducing rigidity and brake hose ferrule corrosion. These won't show up on a standard MOT but can be expensive to fix — repairs start from £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.

Fiat Sedici MOT FAQs
What are the most common MOT failures on a Fiat Sedici?
Based on 30,893 DVSA MOT tests, the most common failure is brake hoses perished or damaged — at 50x the national fleet average. Other frequent failures include suspension component damaged or corroded and fluid leak.
Is the Fiat Sedici reliable based on MOT data?
The Fiat Sedici has 14 MOT failure categories above the fleet average. Specialists also flag structural corrosion reducing 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 Fiat Sedici most commonly fails on transmission joint, belt or chain worn and suspension component damaged or corroded. Under 60,000 miles, the main issues are brake hoses perished or damaged and subframe bushes or mounts worn.
