Should I check the MOT history before buying a 2026 BYD Seal U Boost Dm I PHEV Auto?

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 2026 BYD Seal U Boost Dm I PHEV Auto?

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 2026 BYD Seal U Boost Dm I PHEV Auto?

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.

Do I need an HPI check when buying a 2026 BYD Seal U Boost Dm I PHEV Auto?

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.

Too new to rate yet — worth knowing

Got a specific BYD Seal U Boost Dm I PHEV Auto you're checking out?

The real detail is in the individual vehicle report — MOT history, AI Hunches, mileage timeline, and defect patterns for that specific reg.

This 2026 BYD Seal U has a first-time MOT pass rate of just 0.2%, far below the UK average of 80%, which is a serious red flag for reliability—though the zero dangerous defects recorded is reassuring from a safety perspective. The median mileage of 301 miles suggests these vehicles are brand new or nearly unused at test, making this pass rate even more concerning since they haven't yet accumulated wear.

With an average of zero failures and zero advisories per vehicle, the extremely low pass rate doesn't reflect typical wear-and-tear issues but rather appears to point toward systemic manufacturing or specification problems specific to this model. If you're considering this vehicle, investigate whether there's a known recall or quality issue affecting the 2026 batch, and factor in the likelihood of early remedial work before making a purchase decision.
