Why does the Subaru Outback dashboard warning light stay on after the engine is turned off?
2 Answers
Subaru Outback dashboard warning light stays on after the engine is turned off for the following reasons: Power not turned off: Although the engine is turned off, the power is not turned off, and the dashboard will also be on. At this time, you only need to turn off the power switch and the light switch. Dashboard standby function: After the engine is turned off and the power is also turned off, the dashboard will have a standby function. When the person gets out of the car and closes the door, the dashboard will automatically turn off. The instrument panel is used to install instruments and related devices on a rigid plate or structural part. According to the type, there are screen-type instrument panels, frame-type instrument panels, channel-type instrument panels, and cabinet-type instrument panels. The instrument panel can be equipped with external lighting, and can also be attached to the control console. There are various forms and specifications, and various instruments can be installed as needed. Various instrument panels can also be combined into a whole as needed.
I've encountered this issue a few times, especially with older Outback models. When the dashboard lights stay on after turning off the engine, it usually indicates the electrical system hasn't fully shut down. The most common causes are a stuck relay or the body control module continuing to operate post-shutdown, particularly minor glitches like the anti-theft system. Additionally, loose battery connections can cause this by creating abnormal current return paths, making warning lights mistakenly think the car is still running. If left unaddressed, the battery will gradually discharge until the car won't start. I recommend first opening the hood to check fuses and relays, especially those related to the dashboard, for any signs of melting or sticking. If that doesn't resolve it, drive straight to a Subaru dealership for specialized diagnostic equipment testing—it's affordable and saves hassle, as prolonged issues can affect the entire electrical system's lifespan.
