Should I check the MOT history before buying a 2021 Renault Trucks Master 45?

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 2021 Renault Trucks Master 45?

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 2021 Renault Trucks Master 45?

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 2021 Renault Trucks Master 45?

This 2021 Renault Trucks Master 45 is a genuine concern: only 16% pass their MOT first time versus the UK average of 80%, and the median CarHunch score of 45 signals serious reliability problems across the fleet. With a 4% rate of dangerous defects, these vehicles carry real safety risks that demand careful pre-purchase inspection.

At 79,237 miles on average, these are heavy-use commercial vehicles, which explains the elevated failure rate—but the 0.15 failures and 0.6 advisories per vehicle still suggest this model develops issues faster than typical. If you're considering one, insist on a full pre-purchase inspection by a specialist familiar with Renault truck hydraulics and brake systems, and factor in regular servicing costs.
