The Peugeot 505 draws 1 complaints per production run against 3.72 for the average car — better than typical. Failures cluster at 0 years, so only 0% of them fall inside the 3-year basic warranty.
What actually fails
Systems by number of complaints, with the age at which each typically goes. The age column is the useful one — it tells you what to expect next on a car you already own, and what to inspect on one you are about to buy.
| System | Complaints | Typical age | Crash | Fire |
|---|---|---|---|---|
| Power Train | — | — | — | |
| Electrical System | — | — | 1 | |
| Fuel System | — | — | — | |
| Gasoline | — | — | — |
What else in this class
Same vehicle class, so the comparison is fair — an estate against an estate, not against a coupé.
Good year or bad year — the VIN settles it.
- Check any VIN against complaints for its exact build year and plant
- Exact value for that car, adjusted for its mileage
- Full research report as a PDF you can hand to a mechanic
- Alerts if a recall lands on a car in your garage
- No ads, on every page
- No ads, no tracking — and much more
How we measure it
Reliability scores usually arrive as a number out of five with no working shown. We publish the arithmetic instead, because two things about it are arguable and you should be able to argue with them.
Rate, not total. A model that sold three million units collects more complaints than one that sold thirty thousand, and that says nothing about either. So we divide by the number of production runs — the distinct first-eleven-character VIN prefixes on record. Across 1,100,006 complaints and 295,326 runs the market average works out at 3.72 per run.
Age, not year. Every complaint carries an incident date and a model year, so we can work out how old the car was when it failed. That is what the warranty question turns on, and it is why our «worst year» rankings exclude anything built in the last 6 years — those cars simply have not had time to break yet.
What this is not. A complaint to NHTSA is a deliberate act, so this measures serious faults, not paint that scratched. It says nothing about running costs or how nice a car is to own. And an absence of complaints on a rare model means an absence of owners, not excellence.
