Kia Sorento years to avoid — 96,685 MOT tests ranked

Inspect most carefully: 2004, 2012. Strongest in the data: 2017 or 2018. The ranking uses 96,685 MOT tests across 16 registration years (2023–2025) and compares each year with all UK cars of the same age.

Every Sorento 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 2004 and 2012 rank lower

The 2012 cohort passes 64.6% of tests (-6.6 points versus same-age cars) at a median 102,286 miles, with suspension the leading failure system. The 2004 cohort passes 56.2% of tests (-8.0 points versus same-age cars) at a median 115,498 miles, with suspension 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 2004 example beats a neglected 2017 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.
  • Scan before you pay. A 2-minute OBD scan reveals stored faults the dashboard hides — see our scanner guide.

FAQs

Which Sorento years should I avoid?

Based on 96,685 MOT tests adjusted against cars of the same age, 2004, 2012 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 Sorento year to buy used?

2017 and 2018 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 Sorento reliable overall?

Across 96,685 tests, the median age-adjusted index is 95.6 (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. Association is not proof of a model-year defect. DVSA anonymised data 2023–2025, OGL v3.0.
