Problem overview

Some Hyundai Sonata owners report experiencing serious safety concerns, including engine fires and electrical failures after the vehicle self-shuts down while driving. There have been multiple incidents where these vehicles have caught fire, with flames observed near the engine area, posing risks to both occupants and other road users. Additionally, electrical faults, often related to issues with fuses, relays, and wiring, are frequently cited as causes for sudden shutdowns, which may lead to further electrical failures. Owners are advised to begin diagnostics by checking for stored trouble codes in the vehicle's system, which can help identify the underlying issues. In the event of a shutdown while driving, prioritizing safety by moving to the side of the road is crucial to prevent accidents. Regular maintenance and prompt repairs are essential for addressing known problems, including excessive oil consumption and stalling, particularly in Hyundai Sonata models from 2011 to 2016. Seeking professional assistance and addressing these concerns promptly is vital to mitigate the risks of engine fires and electrical failures.
