There are several reasons why the music cannot be turned off after the car is turned off: 1. Reason one: There is a delay. The delay time varies for different cars. You can observe how long the car's audio system takes to automatically shut down after the engine is turned off. 2. Reason two: Whether the key is used to turn off the engine or not. The first scenario is a circuit malfunction that needs to be checked. The second scenario is normal—the key only turns off the engine but does not cut off the power completely. If the key is still inserted and the switch is not fully turned off, the battery continues to work. 3. Reason three: The audio system's power supply has two live wires. One is a constant power source that remains on to maintain memory functions, while the other is an ACC wire used to control the power on/off, so users don't have to press the switch every time. If both live wires are connected to the constant power source, the audio system will not turn off after the key is removed. In this case, take the car to an audio shop to correct the wiring.

I remember one time my car's audio system kept playing after the engine was turned off. At first, I thought the battery was dead, but later discovered the ignition switch was slightly stuck, preventing the power from fully cutting off. Some cars are designed to maintain power for the audio system for a while after removing the key - this is called the ACC mode delay function. However, if it lasts too long, it can drain the battery and prevent the car from starting. You can check if the dashboard warning lights are still on; if they are, it indicates an electrical issue, possibly a faulty relay or blown fuse. Additionally, modern vehicles have smart systems, and software bugs could cause control module malfunctions. In my case, it took me a while to realize the 'entertainment keep-alive' option was enabled in the settings, and turning it off solved the problem. It's advisable to periodically inspect the electrical system, especially in older cars prone to wiring harness aging. Timely maintenance at a repair shop can prevent bigger troubles.

It's really frustrating when the car turns off but the music won't stop, especially during summer when you want to park and enjoy some cool tunes but can't turn them off. A common reason is that the audio system's delayed shutdown feature is activated—some car models default to providing power for a few minutes after removing the key. Alternatively, the key might not be turned all the way, leaving the power on; in this case, try turning the ignition switch again. Poor wiring connections could also be the culprit—I once fixed it myself by tightening a loose plug. Weak batteries are prone to this issue, as unstable voltage can confuse the system. It's advisable to check the owner's manual to locate the corresponding fuse and temporarily disconnect it as a quick fix to avoid draining the battery. For peace of mind, manually turning off the music before parking is safer than relying on automatic features—this saves power and reduces the chance of malfunctions.

The audio system not turning off after the engine is shut down is usually caused by an electrical circuit or control system malfunction. First, the ignition switch may not be fully disconnected, maintaining partial power supply; second, the audio system's delay function may be activated; third, issues with relays or fuses may cause continuous power supply. Abnormalities may also arise from short circuits or loose connectors. Try checking the key position and performing a simple restart of the audio system. A professional repair shop can use diagnostic tools to measure voltage and check the status of control modules to resolve the issue.
