Pontiac

3 generations across 2 models, built from 9,680 complaints that record mileage at failure.

Each strip places that generation’s mileage-tagged reports on a linear 0–200,000-mile scale: whisker = middle 80%, box = middle half, line = median. † marks recent generations — their fleets are young, so their reports can only have come at low mileages. Compare generations of similar age.
