If your car won’t turn off, there is likely an electrical issue, with the most common causes being a faulty ignition switch, a stuck relay, or electrical system malfunctions. For push-button start vehicles, the problem could also be a weak key fob battery or a malfunctioning brake pedal switch. As a temporary measure, you can try disconnecting the battery to reset the system, but for a permanent fix, you will need to have the car inspected by a mechanic to diagnose and repair the faulty component.
Common Causes
Ignition Switch Failure:
A worn or damaged ignition switch may fail to cut power to the engine, keeping it running even after you turn the key off.
Electrical System Issues:
Problems with wiring, a faulty relay, or a malfunctioning main electrical relay can prevent the engine from shutting down properly.
Stuck Relays:
A stuck fuel cut-off relay or a stuck starter solenoid can keep power flowing to the engine or fuel system, causing it to continue running.
Key Fob Malfunction:
In cars with push-button start, a weak or failing key fob battery can prevent the car from recognizing the command to turn off.
Malfunctioning Brake Pedal Switch:
On push-button start vehicles, a faulty brake pedal switch may fail to signal the car to shut down.
