Hyundai Sonata repeated engine failures, considering a fourth replacement on Hyundai Sonata

Some Hyundai Sonata owners report experiencing repeated engine failures, particularly in models from 2011 to 2016, which may include excessive oil consumption and stalling due to manufacturing defects or inadequate maintenance. These issues have led to recalls and extended warranties from Hyundai, aimed at reducing engine failures and fire incidents in newer models; however, older vehicles may still face unresolved problems without proper servicing. Additionally, some owners find that engine knocking and stalling can result from worn timing belts, faulty fuel systems, or transmission issues, potentially leading to complete engine failure and the need for costly replacements. Hyundai has committed to replacing engines in specific 2011-2019 Sonatas under certain conditions, but owners without the necessary software updates may not qualify for this assistance. Given the significant financial burden of engine replacements, estimated at around $6000 each, and the potential impact on a large number of vehicles, it is recommended that owners consult with Hyundai dealerships or authorized service centers to determine the underlying causes of these failures and explore effective resolutions.
