Toyota Avensis MOT Failures
An analysis of 548,377 real DVSA MOT tests on the Toyota Avensis — what fails, how often, and how that compares to every other car on UK roads. Generations covered: T220 (1997–2003), T250 (2003–2009), T270 (2009–2018).
Where the Toyota Avensis fails its MOT
The single biggest MOT failure point on the Toyota Avensis is emissions failure — this model is 45 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 548,377 MOT tests, 5.44% of all Toyota Avensis tests recorded this as a failure.
Exhaust and emissions failures often point to catalytic converter degradation, lambda sensor faults, or — in diesel models — DPF problems. These can be expensive to fix and will cause an immediate MOT failure.
Other notable weak points include brake pipes corroded (25x the fleet average), suspension component fractured or (24x the fleet average), light unit fault (21x the fleet average), and transmission shaft bent or badly damaged (49x the fleet average). These ratios compare the Toyota Avensis'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 5 categories: Exhaust & Emissions, Brakes, Suspension, Lights & Electrics, Bodywork. If you're inspecting a Toyota Avensis 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 Toyota Avensis'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 Toyota Avensis specifically, the DVSA data shows the most common failures at this mileage are headlight fault (41x the average) and brake pipes corroded (25x). brake hoses perished or damaged (22x) and suspension component damaged or corroded (21x) 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 Toyota Avensis specifically, the DVSA data shows the most common failures at this mileage are transmission shaft bent or badly damaged (49x the average) and emissions failure (45x). suspension ball joints worn (31x) and suspension component fractured or (24x) 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 Toyota Avensis specifically, the DVSA data shows the most common failures at this mileage are component worn or corroded (298x the average) and transmission shaft bent or badly damaged (39x). tyre wear or damage (32x) and suspension component fractured or (20x) also appear frequently.
The shift from headlight fault at lower mileages to component worn or corroded 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 Toyota Avensis specialists and owners flag most frequently, drawn from manufacturer technical bulletins, workshop data, and verified owner reports.
Brake pipe corrosion (T220/T250/T270) Dangerous
Brake pipe corrosion is a documented safety critical issue on all Avensis generations, with MOT failure rates up to 25.3 times the fleet average. Affects T220, T250, T270; typical independent garage repair cost is £250–£600.
Suspension component corrosion and damage (T220/T250/T270) Major
Front suspension components including lower control arms, anti-roll bar links, and subframe mounting points are prone to accelerated corrosion on all Avensis generations. Affects T220, T250, T270; typical independent garage repair cost is £200–£800.
Petrol engine emissions system failures (T220/T250/T270) Major
Petrol Avensis models show exceptionally high emissions test failure rates, with MOT data recording up to This affects both catalyst efficiency and lambda sensor operation, particularly on 1.8-litre VVT-i and Valvematic engines. Affects T220, T250, T270; typical independent garage repair cost is £300–£1,200.
Electronic parking brake malfunction (T270) Major
Third-generation Avensis models equipped with electronic parking brake systems show failure rates 24.9 times the fleet average for parking brake malfunction indicator lights. Affects T270; typical independent garage repair cost is £300–£600.

What to check before buying a Toyota Avensis
Based on the MOT failure data and known issues above, here's what to prioritise when inspecting a Toyota Avensis:
Exhaust & Emissions — check for emissions failure. Brakes — check for brake pipes corroded, parking brake inefficient. Suspension — check for suspension component fractured or, suspension ball joints worn, suspension component damaged or corroded. Lights & Electrics — check for light unit fault.
Beyond the MOT items, ask specifically about brake pipe corrosion and suspension component corrosion and damage. These won't show up on a standard MOT but can be expensive to fix — repairs start from £250. 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.
