Kia Optima (2020)
2020 Kia Optima
CarHunch analysed 130 real MOT records for the 2020 Kia Optima. This breakdown of actual test outcomes — pass rates, defect profiles, mileage data — isn't published anywhere else.
The 2020 Kia Optima is more reliable than the UK average, with an 88.9% first-time pass rate against the typical 80%, and only 18.5% of vehicles showing dangerous defects—a manageable level for this age group. That said, owners should expect around 3.8 advisories per test, suggesting minor wear items crop up regularly.
At 46,196 miles median (54,410 average), these cars have been driven moderately and are still relatively young, so the 0.54 average failures per vehicle reflects normal ageing rather than systemic weakness. When you're viewing examples, focus your pre-purchase inspection on suspension components and exhaust systems—the two most common failure categories—and get a full diagnostic to confirm no hidden advisories are being overlooked.
What to check before buying a 2020 Kia Optima
Practical pre-purchase checks for this age and model.
- 📋 Check the full MOT history. Look for recurring advisories — slow-building issues like corrosion or brake wear patterns show up years before they become failures. Enter the reg below for a full AI analysis.
- 🔍 Inspect for corrosion in person. Brake pipes, sills, subframes, and chassis legs. Surface rust is normal at this age; structural rust is a serious problem that's expensive to fix and can fail an MOT.
- 🛞 Check tyres and brakes. The most common advisory items at this age. Budget for replacement if they're near the limit — factor this into your offer price.
- 📄 Run an HPI check. The MOT history won't show outstanding finance, insurance write-offs, or stolen status — an HPI check will.
