2006 Subaru B9 Tribeca

CarHunch analysed 157 real MOT records for the 2006 Subaru B9 Tribeca. This breakdown of actual test outcomes — pass rates, defect profiles, mileage data — isn't published anywhere else.

The 2006 Subaru B9 Tribeca passes its MOT first time in 78.1% of cases, just below the UK average of 80%, and carries a notable reliability concern: 27.4% of these vehicles have recorded a dangerous defect at some point, well above acceptable levels. This elevated hazard rate should give any prospective buyer pause.

These cars are sitting at a reasonable 65,935 miles median for their age, yet they're racking up 3.15 failures and 14.9 advisories per test on average—suggesting wear is catching up faster than mileage alone would predict. Before committing to one, have a pre-purchase inspection focus on the systems that commonly fail: suspension, cooling, and brake components are likely culprits given this advisory load.

What to check before buying a 2006 Subaru B9 Tribeca

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.
  • ⚠️ 27.4% of these vehicles have had a dangerous defect recorded. Enter the reg below — the full MOT history will show exactly what was flagged and whether it was resolved.
  • 📄 Run an HPI check. The MOT history won't show outstanding finance, insurance write-offs, or stolen status — an HPI check will.
