Klunk – Reliability Scores for Used Cars
Reliability scores on every used car listing
Klunk = a 0-100 reliability score for every model year of every car, built on NHTSA's owner-complaint database. What's different: • Per-year scoring (not averaged across a nameplate's lifetime) • Chrome extension overlays scores on Carvana/AutoTrader/Cars.com listings as you shop • Every score traces back to actual NHTSA complaint IDs • Free, no signup, no paywall Edmunds tells you "the Honda Civic is reliable." Klunk tells you which year of Civic actually is.
Hey PH 👋
I'm Dan, indie dev at PrimeStack Solutions. I started Klunk as a side project after going deep on NHTSA's owner-complaint data. Decades of owner-reported issues exist for every car you can buy, but nobody had
built a tool that turns all that signal into a single number you can compare across cars. So I built a pipeline that normalizes the data into a 0-100 score per make/model/year.
A few things that make it different from existing options:
• Scores every model year individually. "The Honda Civic is reliable" is useless when the 2016 has issues the 2017 doesn't. Klunk pinpoints the specific year to buy or avoid.
• The Chrome extension drops the score onto Carvana, AutoTrader, and Cars.com listings while you shop. No tab switching.
• Every score traces back to actual NHTSA complaints. You can click through and see what owners are reporting.
• No signup, no paywall.
I'm here to get real feedback from people who'll actually use it. Try it on a car you've owned, a car you're shopping right now, or drop a make/model/year in the comments and I'll pull the data for you live.
Happy to answer anything about the methodology, the scoring, the extension, whatever.
Dan
