Problem overview

Some Hyundai Sonata owners report experiencing starting issues despite the vehicle indicating that it is on. Common culprits include a faulty starter motor, which can prevent the engine from turning over, and a malfunctioning ignition switch that may hinder proper starting. Additionally, problems with the starter system, such as a faulty starter, starter relay, or ignition switch, could contribute to this issue. Loose or corroded connections in the starter system may also lead to a situation where power is present but the car fails to start. Furthermore, issues with the fuel system, such as insufficient fuel or a malfunctioning fuel pump, can result in a no-start condition. Owners have also noted that dirty battery connections, ignition system problems, or issues with the car's security system could be potential reasons for the starting failure, despite having a good battery. Accurate diagnosis of the specific cause is essential for effective resolution and to restore the Hyundai Sonata's functionality.
