Moderate sample. 382 vehicles on record. Figures are indicative — the specific vehicle's history matters more than these averages.
The 2003 Prius falls just short of the UK average with a 77.8% first-time pass rate, but the real concern is that 34.8% of these cars have experienced a dangerous defect at some point—nearly double the typical threshold for worry. This suggests age-related wear is catching up with the model, and potential buyers should factor in the elevated risk of serious faults.
At nearly 88,000 miles on average, these Priuses have covered reasonable mileage for their age, yet they're generating 4.3 failures and 23.0 advisories per vehicle—the advisories pointing to creeping wear across multiple systems rather than catastrophic breakdown. Before committing to one, get a full pre-purchase inspection focused on hybrid battery condition and brake performance, as these ageing hybrids can hide expensive repairs behind their economical reputation.
The 2003 Toyota Prius has a decent first-time pass rate (77.8%), 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 382 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.
