London Taxis Int Tx4 MOT Failures
An analysis of 262,053 real DVSA MOT tests on the London Taxis Int Tx4 — what fails, how often, and how that compares to every other car on UK roads.
Where the London Taxis Int Tx4 fails its MOT
The single biggest MOT failure point on the London Taxis Int Tx4 is steering rack wear — this model is 330 times more likely to fail on this item than the average car on UK roads. That makes it an extreme outlier for anyone buying or owning this model. Across 262,053 MOT tests, 2.5% of all London Taxis Int Tx4 tests recorded this as a failure.
Steering faults include worn track rod ends, power steering leaks, and rack wear. These are safety-critical — any play in the steering should be investigated immediately.
Other notable weak points include suspension pin, bush or joint worn (91x the fleet average), abs fault (183x the fleet average), brake pedal anti-slip provision missing, loose ... (387x the fleet average), and tyre incorrectly seated on the wheel rim (230x the fleet average). These ratios compare the London Taxis Int Tx4's failure rate on each item against the national average for all cars tested — a ratio of 10x means this model fails ten times more often than a typical car.
The failures span 7 categories: Steering, Suspension, Bodywork, Brakes, Tyres and others. If you're inspecting a London Taxis Int Tx4 before purchase, these are the areas to focus on — and if any have been flagged as advisories on a previous MOT, they're likely to become failures in the near future.
How failures change with mileage
The London Taxis Int Tx4's weak points shift as the car covers more miles. Understanding these patterns helps you know what to expect — and what to budget for — at each stage of ownership.
Under 60,000 miles
At this mileage, most failures are either design-related or caused by age rather than wear. Components like bushes and drop links may not have been replaced yet, and original-fit parts can deteriorate even on low-mileage cars that spend a lot of time sitting.
For the London Taxis Int Tx4 specifically, the DVSA data shows the most common failures at this mileage are steering rack wear (330x the average) and free play in the steering, measured at the rim ... (293x). abs fault (183x) and tyre fouling a part of the vehicle (145x) also appear frequently.
60,000 to 100,000 miles
This is where routine wear items start to show up. Brake components, tyres, and exhaust parts have done serious work by this point. Cars that have been well serviced will show fewer of these failures — this mileage band is where good maintenance really separates the well-kept from the neglected.
For the London Taxis Int Tx4 specifically, the DVSA data shows the most common failures at this mileage are tyre incorrectly seated on the wheel rim (230x the average) and wheel with a loose or missing wheel nut, bolt o... (227x). steering rack wear (161x) and abs fault (83x) also appear frequently.
Over 100,000 miles
High-mileage cars accumulate failures across multiple systems. The key question isn't whether things will need doing — they will — but whether the car has been maintained well enough to keep on top of them. Look for a consistent service history and recent MOT passes with minimal advisories.
For the London Taxis Int Tx4 specifically, the DVSA data shows the most common failures at this mileage are brake pedal anti-slip provision missing, loose ... (387x the average) and suspension component insecurely attached to cha... (151x). tyre incorrectly seated on the wheel rim (100x) and external damage (78x) also appear frequently.
The shift from steering rack wear at lower mileages to brake pedal anti-slip provision missing, loose ... at higher mileages is typical — early failures tend to be design or factory-related, while high-mileage failures reflect accumulated mechanical wear. A car that's been well maintained will usually dodge the worst of both.
