Ford Expedition loud noise when turning ignition, new starter issues despite tested battery on Ford Expedition

Some Ford Expedition owners report experiencing a loud repetitive clicking or popping noise from the engine compartment when trying to start their vehicle, which may indicate a depleted battery that has enough charge to trigger the solenoid but not enough power for the starter. Others have noted that a high-pitched clicking noise could suggest a bad starter motor, often linked to low battery voltage. Additionally, some owners hear a buzzing sound from the starter relay, which may point to issues with the relay or related components. In colder weather, some Expeditions may have a frozen or stuck starter motor, leading to grinding noises during ignition attempts. Furthermore, problems with the ignition switch can prevent proper voltage supply to the starting circuit, causing the starter solenoid to partially engage and create grinding sounds. To resolve these issues, it is recommended that owners check battery health, inspect the starter motor, and ensure all connections are clean and secure, and consult a mechanic if problems persist.
