Toyota Avensis years to avoid — 184,710 MOT tests ranked

Inspect most carefully: 2018. Strongest in the data: 2010 or 2011. The ranking uses 184,710 MOT tests across 18 registration years (2023–2025) and compares each year with all UK cars of the same age. Fuel-type signal: diesels show an average 5.0-point pass-rate deficit on this model. That may reflect mileage and use as well as the car itself, so inspect DPF and emissions history rather than treating fuel type as a verdict.

Every Avensis year, ranked

The age-adjusted MOT index sets 100 as the pass rate of all UK cars registered in the same year and tested in the same calendar year. Higher is better. This prevents an old car being labelled a “bad year” simply because it is old.

Why 2018 rank lower

The 2018 cohort passes 86.2% of tests (-0.2 points versus same-age cars) at a median 77,227 miles, with tyres the leading failure system. This is population-level evidence, not a known-fault list: service history, engine version and the individual MOT record can outweigh the registration-year average.

How to use this before buying

  • Rankings describe the cohort, not the car. A cherished 2018 example beats a neglected 2010 one — always run the specific reg through the free MOT history check.
  • Read the advisories. Repeated notes for the same component across years mean the owner has been ignoring it. Decode them in our advisory library.
  • Fuel matters on this model. The diesel deficit (5.0 points) usually traces to DPF and emissions kit on low-mileage use — check for P2463-type soot codes on the test drive.
  • Scan before you pay. A 2-minute OBD scan reveals stored faults the dashboard hides — see our scanner guide.

FAQs

Which Avensis years should I avoid?

Based on 184,710 MOT tests adjusted against cars of the same age, 2018 are the lower-scoring outliers. That is a prompt for closer inspection, not proof that every car from those years is bad.

What is the best Avensis year to buy used?

2010 and 2011 lead the age-adjusted MOT ranking. The score compares each registration year with all UK cars of the same age; the specific car's history and condition still take priority.

Is the Avensis reliable overall?

Across 184,710 tests, the median age-adjusted index is 104.1 (100 equals the pass rate of all cars registered in the same year). Use the spread between years as one signal, then check the individual registration.

Methodology: index = 100 + the model-year cohort’s MOT pass-rate difference versus all UK vehicles registered in the same year and tested in the same calendar year. Class 4 initial tests only; retests excluded; at least 1,500 tests per page. “Inspect” years are below both the same-age baseline and the model’s median index by at least 2 points.
