What could be the reason for a Hyundai Sonata making a clicking noise but not starting?

If your Hyundai Sonata won't start and is making a clicking sound, it could be due to a dead battery or a malfunctioning alternator, which is responsible for charging the battery. When the clicking noise is electrical, it means the starter, which is powered by the battery to start the engine, is not receiving sufficient power. Ensure that the connections on your battery are secure and clean to avoid corrosion issues. If the engine starts but immediately dies, it indicates that the alternator is not effectively maintaining the battery's charge. If jump-starting the car works but it fails to start on its own power later, then a dead battery is likely the culprit. Most automobile parts retailers, such as Advance Auto Parts, provide complimentary testing for both the battery and alternator. Plus, these stores often offer free installation services for batteries purchased from them.
