Should I check the MOT history before buying a 2003 Hyundai Sonata?

Yes. Look for recurring advisories — slow-building issues like corrosion or brake wear patterns show up years before they become failures. A full MOT history analysis will highlight patterns that a single test result won't reveal.

What corrosion should I look for when inspecting a 2003 Hyundai Sonata?

Check brake pipes, sills, subframes, and chassis legs. Surface rust is normal at this age; structural rust is a serious problem that is expensive to fix and can fail an MOT.

How are tyres and brakes typically on a 2003 Hyundai Sonata?

Tyres and brakes are the most common advisory items on vehicles of this age. Budget for replacement if they are near the limit, and factor this into your offer price.

The 2003 Hyundai Sonata trails the UK average pass rate by 3.7 points at 76.3%, which is a modest shortfall but worth noting—and a quarter of these cars have recorded dangerous defects at some point, which is a genuine buyer concern that warrants a thorough pre-purchase inspection. These are older, relatively high-mileage examples (averaging 63,425 miles for their age), and they're picking up an average of 3.37 failures and 17.4 advisories per MOT, suggesting mounting wear across multiple systems rather than isolated weak points.

The high advisory count reflects typical degradation on a 20-year-old car rather than catastrophic reliability issues, but the dangerous defect rate does indicate this generation had some design or build vulnerabilities. If you're considering one, factor in the cost of addressing several small problems rather than banking on getting a clean bill of health.

The 2003 Hyundai Sonata passes its MOT first time at roughly the UK average rate (76.3%) — solid but worth checking this vehicle's history carefully.

⚠️ Over 1 in 5 of these vehicles have had a dangerous MOT failure at some point — usually tyres or brakes, and often a one-off issue rather than a persistent problem. The group stats won't tell you which one you're looking at.

For context

🔧 Average reliability. Passes at roughly the UK rate — not a standout, not a problem vehicle. Individual history makes all the difference.

🔧 Expect consumable spend. An average of 17.4 advisories per vehicle tells you wear items (tyres, brakes) get flagged regularly. Budget for them — they're not surprises.

🔍 The dangerous defect figure is real. Most are one-off tyre failures or brake issues — not structural problems. But it's exactly why checking the individual vehicle's history is essential, not optional.

These stats describe 584 vehicles as a group. The specific vehicle you're looking at could be the one good example or the one outlier. Run its registration to find out.
