URGENT UPDATE: Kia and Hyundai have just announced a significant recall affecting 333,590 vehicles due to a serious defect that may cause fuel tanks to melt. This alarming issue involves 250,547 Kia K5 models from 2021 to 2024 and 85,043 Hyundai Sonata vehicles from 2020 to 2023, all equipped with 1.6-liter turbocharged engines.

Dealers are prepared to conduct inspections and replace the faulty check valve at no cost to owners. They will also inspect the fuel tank assembly for damage and update the engine control unit software where necessary.
