💡 What does the warranty cliff mean?
The Harley-davidson Iron 883 Xl N 13 actually sees a 50% decrease in failure rate after the warranty period. This is likely due to survivorship bias — unreliable cars are already off the road by this age. Peak failure occurs at age 3 (20.8% fail rate).
Note: pass rates may improve for very old vehicles due to survivorship bias — only well-maintained cars remain on the road.
