Should I check the MOT history before buying a 1998 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 1998 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 1998 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.

Is the 1998 Hyundai Sonata reliable?

Based on MOT data from 822 vehicles, the 1998 Hyundai Sonata has a first-time MOT pass rate of 68.7%, indicating average reliability for its class. Always check the full MOT history of any specific vehicle before buying.

What are common problems with the 1998 Hyundai Sonata?

These figures are based on actual MOT test records — search a specific registration on CarHunch to see its individual history.

Do I need an HPI check when buying a 1998 Hyundai Sonata?

Yes. The MOT history will not show outstanding finance, insurance write-offs, or stolen status. An HPI check covers these areas and should be part of any used car purchase.

This 1998 Hyundai Sonata has a 68.7% first-time pass rate, noticeably below the UK average of 80%, signalling that age and wear have taken their toll on this cohort. With 14.8% of vehicles having recorded a dangerous defect at some point, these are ageing cars that need careful inspection before purchase.

At 77,000 miles median mileage for a 26-year-old car, these Sonatas are relatively well-used but not excessively so. The average vehicle carries 2.07 failures and 6.1 advisories per test, pointing to steady degradation in brakes, suspension, and emissions systems—so budget for ongoing work and have a pre-purchase inspection focus on these areas.

The 1998 Hyundai Sonata has a below-average first-time pass rate (68.7% vs ~80% UK average) — check the specific vehicle's full MOT history carefully before buying.

⚠️ Around 1 in 8 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

⚠️ Below average. More vehicles in this cohort fail their first MOT than typical. Scrutinise this vehicle's history — look for recurring issues, not just the latest result.

🔧 Expect consumable spend. An average of 6.1 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 822 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.
