The TX4's 75.3% first-time pass rate sits noticeably below the UK average of 80%, signalling below-average reliability for its age—but the real concern is that 54.8% of these vehicles have recorded dangerous defects at some point, substantially higher than typical, making thorough pre-purchase inspection essential. These are London taxis that have clocked up serious miles (median 151,133), and the 6.59 average failures per vehicle reflects the wear: you're looking at a car that demands attention.
With nearly 18 advisories per vehicle on average, the TX4 is prone to minor issues accumulating over time, though this partly reflects its intensive commercial past rather than catastrophic design flaws. Before committing to one, insist on a full independent mechanic's inspection focusing on its suspension, brakes, and emissions systems—the high dangerous-defect rate suggests these areas need particular scrutiny.
The 2012 London Taxis Int Tx4 has a decent first-time pass rate (75.3%), but a higher-than-average share of vehicles have had serious defects recorded — the individual vehicle's history matters a lot here.
These stats describe 842 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.
