The Hyundai and Kia Theta II class action settlement is one of the largest engine-related consumer settlements in U.S. history. It covers connecting rod bearing failure across millions of 2.0L and 2.4L Theta II engines built between 2011 and 2019. This page walks through eligibility, the KSDS recall, the lifetime engine warranty, and exactly how to file a reimbursement claim if you have already paid for repairs.
If you own (or owned) a 2011-2019 Hyundai or Kia with a 2.0L or 2.4L Theta II and ever experienced engine knock, stalling, or replacement, you may qualify for free engine repair, lifetime warranty, or reimbursement of past out-of-pocket costs.
Once the KSDS software recall is performed, eligible VINs carry a lifetime warranty against engine seizure caused by rod bearing failure. Coverage transfers to subsequent owners with documented service.
