Hyundai Sonata engine failure likely due to oil pump malfunction, replacement options available on Hyundai Sonata

Some Hyundai Sonata owners report experiencing engine failure potentially caused by an oil pump malfunction, leading to excessive oil consumption and possible engine damage. These issues may necessitate engine replacement due to mechanical failure or overheating. Owners often consider options such as replacing or rebuilding the engine when faced with these problems. Hyundai provides a free lifetime engine replacement warranty for certain models with 2.4-liter and 2.0-liter turbo Theta II engines, which can be accessed through local dealerships if eligible. Additionally, an extended warranty under the Hyundai service campaign T3G is available for knocking 2.0L turbo and 2.4L GDI engines in specific Sonata models, covering up to 10 years or 120,000 miles. Cost considerations for a new or refurbished engine vary based on the model year, with older models generally offering cheaper replacement options. Furthermore, the Theta II settlement addresses bearing failure for all 2.4 and 2.0 Theta II engines for a lifetime, regardless of ownership history. It is essential for owners to explore these replacement options and warranties to effectively address engine issues and ensure the vehicle's longevity.
