Dennis Unknown (2009)
2009 Dennis Unknown
CarHunch is tracking 744 2009 Dennis Unknown vehicles on UK roads. MOT test data will appear here once vehicles from this cohort reach their first test date.
This 2009 Dennis is a commercial vehicle with a deeply troubling MOT record: only 20% pass first time against the UK average of 80%, and the diesel variants in this dataset show a 0% pass rate entirely. With 744 vehicles analysed, this isn't noise—it's a pattern that signals serious structural reliability issues across the model line.
The average mileage of 208,392 miles is high for a 15-year-old vehicle, but that doesn't explain the catastrophic pass rate; even accounting for heavy use, a 0% diesel pass rate on 742 vehicles suggests systemic design or maintenance problems. If you're considering one of these, budget for immediate and substantial repairs, verify full service history meticulously, and have an independent pre-purchase inspection by a specialist in commercial vehicles—this is not a casual buy.
We have 744 2009 Dennis Unknown vehicles on record but don't have enough MOT test data to show reliable statistics for this cohort.
What to check before buying a 2009 Dennis Unknown
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.
