Accepted Answer

The 2.4 GDI (Theta II) can suffer connecting rod bearing failure from manufacturing debris, causing knocking, loss of power, stalling and in some cases engine fire. Hyundai and Kia recalled vehicles, installed knock sensor detection software (KSDS) and extended engine warranties on many models.
