Possible Causes:
* Starter motor solenoid may be stuck. The starter motor solenoid is an electrical switch that engages the starter motor and turns the engine over. If it gets stuck in the engaged position, it will keep trying to start the engine even after it's already running.
* Ignition switch may be faulty. The ignition switch is what you turn to start the car. If it's faulty, it may not be sending the "off" signal to the starter motor when you turn it off.
* Wiring issue. There may be a loose or damaged wire that is causing the starter motor to get power even when it shouldn't.
Solutions:
* Stuck starter motor solenoid: You can try tapping the starter motor with a hammer to see if it will disengage. If this doesn't work, you will need to replace the starter motor.
* Faulty ignition switch: You will need to replace the ignition switch.
* Wiring issue: You will need to find the loose or damaged wire and fix it.
