The 2009 London Taxis Int TX4 passes its MOT first time only 73.3% of the time, notably below the UK average of 80%, and nearly half of all TX4s on record (47.4%) have suffered a dangerous defect at some point—a serious concern for prospective buyers. The diesel-only fleet shows no meaningful variation from this figure, so fuel type won't improve your odds here.

These cabs have covered substantial mileage for their age, sitting at a median of 187,566 miles, yet still rack up an average of 5.9 failures and 19.2 advisories per test, suggesting wear and deferred maintenance are endemic to the model. If you're considering a TX4, budget for active fault-finding and repairs before purchase; inspect service history carefully and have a pre-buy diagnostic done to catch dangerous defects early.

The 2009 London Taxis Int Tx4 has a below-average first-time pass rate (73.3% vs ~80% UK average) — check the specific vehicle's full MOT history carefully before buying.

⚠️ Over 1 in 5 of these vehicles have had a dangerous MOT failure at some point — usually tyres or brakes, and often a one-off issue rather than a persistent problem. The group stats won't tell you which one you're looking at.

For context
⚠️ Below average. More vehicles in this cohort fail their first MOT than typical. Scrutinise this vehicle's history — look for recurring issues, not just the latest result.
🔧 Expect consumable spend. An average of 19.2 advisories per vehicle tells you wear items (tyres, brakes) get flagged regularly. Budget for them — they're not surprises.
🔍 The dangerous defect figure is real. Most are one-off tyre failures or brake issues — not structural problems. But it's exactly why checking the individual vehicle's history is essential, not optional.

These stats describe 1,417 vehicles as a group. The specific vehicle you're looking at could be the one good example or the one outlier. Run its registration to find out.
