Engine & cooling recalls

The engine assembly and its cooling circuit — blocks, heads, timing components, coolant pumps and radiators. Overheating and oil-leak defects often carry fire risk.

Campaigns by year issued

Counts are of campaigns received by NHTSA in each calendar year. They are not normalised by how many vehicles were on the road, so a taller bar does not by itself mean the system became less reliable.

Method & limitations

Campaigns are grouped by the first segment of NHTSA's component path and mapped to this system through a published alias table. Counts reflect campaigns in the VerifyTheVehicle index, which covers a subset of all US vehicles, and are not defect rates — we hold no registration or sales denominator that would make a rate honest.
