The 2004 Toyota Corolla's 78% first-time pass rate sits slightly below the UK average of 80%, suggesting modest reliability concerns for a vehicle now 20 years old. More troubling is that 35.1% of these cars have recorded a dangerous defect at some point, well above what you'd want to see and a genuine buyer concern that warrants a careful pre-purchase inspection.
These Corollas are running around 73,716 miles on average—reasonable for their age—but they're racking up 4.09 failures per test and 23.2 advisories, indicating wear across multiple systems rather than one critical weakness. If you're considering one, budget for ongoing maintenance and insist on a full diagnostic check; the high dangerous defect rate means skipping this step is false economy.
The 2004 Toyota Corolla has a decent first-time pass rate (78%), 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 25,786 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.
