Renault Trucks Master 45 (2021)
2021 Renault Trucks Master 45
CarHunch analysed 126 real MOT records for the 2021 Renault Trucks Master 45. This breakdown of actual test outcomes — pass rates, defect profiles, mileage data — isn't published anywhere else.
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.
What to check before buying a 2021 Renault Trucks Master 45
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.
