Reported problems
What owners actually complained about, which component failed, and at what mileage.
Public-record vehicle research
Every complaint, recall, defect investigation, manufacturer bulletin, crash rating and fuel-economy figure the US government holds for a model year, in one report.
What is in a report
What owners actually complained about, which component failed, and at what mileage.
Campaign numbers, the defect, the consequence, and the remedy the manufacturer offered.
Open NHTSA defect investigations, and the bulletins manufacturers sent their dealers.
NHTSA frontal, side and rollover results for each tested configuration.
EPA city, highway and combined figures for every engine and transmission.
The same measures across every year of a model, so a bad year stands out.

If you would rather look than search, the index lists every manufacturer with a complaint, recall or investigation filed against it, and every model underneath.
Complaint totals are reports submitted to NHTSA, not population-adjusted failure rates. A model that sold in large numbers will collect more complaints than a rare one that fails more often, so compare model years of the same car rather than different cars by raw count.
