Hyundai Sonata no power issue with failure to start and no security light on Hyundai Sonata

Some Hyundai Sonata owners report experiencing no power issues, where the vehicle fails to start and the security light does not illuminate. A common reason for this problem is a weak or dead battery, which can prevent the engine from cranking or cause it to crank slowly. Additionally, some owners have encountered electrical or wiring issues that contribute to the no-start condition. It is also recommended that owners check the starter motor to ensure it is turning over; if it is, the issue may lie with the fuel or ignition systems. Other potential causes for the starting failure include problems with the fuel system, ignition system, or alternator, as well as issues with the immobilizer light not activating, indicating a possible security system malfunction. Owners are advised to perform basic checks on the battery, electrical components, and starter motor, and to seek further diagnostics from a qualified mechanic if the problem persists.
