Hyundai/Kia Theta II Engine: Complaint and Recall Record

NHTSA complaint counts are self-selected reports. They are not normalised for sales volume and they are not a reliability score. YearTell does not publish stars, “best year” lists or advice to avoid a vehicle.

Some Hyundai and Kia years in the snapshot are engine-heavy in the NHTSA file. This guide points at those year-pages. It does not rank engines and it does not tell you to avoid a nameplate.

Open the year-page for the campaign list and the narratives. Confirm open recalls at nhtsa.gov. Counts remain unadjusted for sales volume.

Engine-heavy years in this snapshot are a reason to read the ENGINE row and the related campaigns, not a reason to discard a nameplate from a phone listing. The car in front of you still needs an inspection.

Use the Tucson, Santa Fe, Sorento and related year-pages linked from those hubs. This guide does not keep a separate engine catalogue.

This page points at year-records where engine is the leading named system. It is not a list of engines to avoid.

How YearTell builds these numbers
