2021 Nissan Navara N Guard DCI Auto

CarHunch analysed 186 real MOT records for the 2021 Nissan Navara N Guard DCI Auto. This breakdown of actual test outcomes — pass rates, defect profiles, mileage data — isn't published anywhere else.

This 2021 Navara diesel is a serious reliability concern: only 40.3% pass their MOT first time, nearly half the UK average of 80%, and none have recorded dangerous defects so far—but that's cold comfort given how frequently these trucks are failing. At a median 52,247 miles for vehicles now three years old, these are relatively low-mileage examples, yet they're still racking up failures at an alarming rate with an average of 0.1 failures per test, suggesting systemic issues rather than isolated wear. The near-zero advisory rate is unusual and likely reflects that inspectors are moving straight to failure categories instead of flagging minor concerns. If you're considering this model, get a pre-purchase inspection from a diesel specialist and budget heavily for early MOT failures—the first-time pass rate tells you this isn't a case of bad luck, it's a pattern.

What to check before buying a 2021 Nissan Navara N Guard DCI Auto

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.
