Counts are not adjusted for sales. The more cars of a model there are on the road, the more complaints it draws, so the raw totals above say a lot about sales. Everything below compares shares of each model's own complaints, the mileage problems start at, recalls per model year and each model's years against its own median.

Share of each model's own complaints, with the count beside it. "Most in" links to the symptom sheet for the model year with the most reports of it, and the mileage is the median from reports that gave one.

When problems start

Accord owners report problems earlier. Half the Accord complaints that give a mileage come before 35,000 miles; for the K5 the halfway point is 45,000. 52% of K5 reports and 60% of Accord reports come before 50,000 miles. Older model years have had longer to reach high mileage, so a window that runs to recent years pulls both medians down.

Each bar is that model year's complaints for each year on the road, divided by the same figure for a typical year of the same model (the dashed line). Measuring each model against itself takes the sales gap between the two out of the picture, so they can share a scale. Years too new to judge are left out.

Recalls and investigations

The two draw recalls at about the same rate: 2.0 campaigns per model year for the K5 and 2.2 for the Accord. A recall counts once however many cars it covers, so this figure does not grow with sales the way complaint totals do.
