Porsche 911 Carrera vs BMW I4
Both cars' complete complaint records, side by side.
Read the totals carefully. NHTSA publishes no sales figures, so the car that sold more collects more complaints regardless of quality. The rows worth weighing are the proportions — the share of complaints that involved harm, and which part dominates.
