Reliability by Source

Each independent organization measures reliability differently. TÜV reports inspection defect rates by age band. ADAC reports pan-European breakdowns per 1,000 vehicles. NHTSA aggregates US consumer complaints. DVSA MOT data is the UK fleet's annual safety inspection — every car 3+ years old. Lower variance across sources = higher confidence in the composite.
