Citroen C3 Aircross MOT Failures
An analysis of 143,265 real DVSA MOT tests on the Citroen C3 Aircross — what fails, how often, and how that compares to every other car on UK roads.
Where the Citroen C3 Aircross fails its MOT
The single biggest MOT failure point on the Citroen C3 Aircross is exhaust system damage — this model is 11 times more likely to fail on this item than the average car on UK roads. That makes it worth watching for anyone buying or owning this model. Across 143,265 MOT tests, 2.49% of all Citroen C3 Aircross 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 brake hoses perished or damaged (14x the fleet average), transmission shaft constant velocity joint boot... (6.7x the fleet average), brake disc or drum significantly and worn (8.1x the fleet average), and brake pipes corroded (6.9x the fleet average). These ratios compare the Citroen C3 Aircross'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 3 categories: Bodywork, Brakes, Lights & Electrics. If you're inspecting a Citroen C3 Aircross 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 Citroen C3 Aircross'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 Citroen C3 Aircross specifically, the DVSA data shows the most common failures at this mileage are brake hoses perished or damaged (14x the average) and exhaust system damage (11x). brake disc or drum significantly and worn (8.1x) and brake pipes corroded (6.9x) 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.
The standout failure at this mileage is exhaust system damage at 6.4x the fleet average.
The shift from brake hoses perished or damaged at lower mileages to exhaust system damage 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.
What to check before buying a Citroen C3 Aircross
Based on the MOT failure data and known issues above, here's what to prioritise when inspecting a Citroen C3 Aircross:
Bodywork — check for exhaust system damage, transmission shaft constant velocity joint boot.... Brakes — check for brake hoses perished or damaged, brake disc or drum significantly and worn, brake pipes corroded.
Always check the car's full MOT history for patterns — recurring advisories often become failures within 12 months. Enter any reg into our free car check to see the complete picture.
