Recall distribution by component

5 component categories

Counts and shares use the vehicle-level recall records shown below. The horizontal bar is scaled to the largest category on this page.
Component	Campaigns	Share
SEAT BELTS	2	33.3%
TIRES	1	16.7%
SERVICE BRAKES, HYDRAULIC	1	16.7%
LATCHES/LOCKS/LINKAGES	1	16.7%
POWER TRAIN	1	16.7%

Component labels follow the source record's component field. Where the source includes a more detailed subcomponent after a colon, this distribution groups the record under the first component segment. Shares are calculated against 6 campaigns and rounded to one decimal place, so displayed percentages may not sum to exactly 100 percent.

Recall dates by calendar year

3 calendar years

These are recall notice dates, not vehicle model years.
Calendar year	Campaigns	Relative volume
2020	2
