Why does the Roewe 550 still have power to the body after the key is removed?

It could be that the ignition lock's key detection switch occasionally malfunctions, causing the body computer to think the key is still inserted. Below are specific details about the Roewe 550: 1. Body dimensions: The wheelbase is 2705mm. The length, width, and height are 4648mm, 1827mm, and 1483mm respectively, with a fuel tank capacity of 62 liters. 2. Features: The Roewe 550 is equipped with a TST 6-speed oil-cooled dual-clutch automatic transmission system, Inkanet-3G digital intelligent network driving system, Start-Stop digital intelligent energy-saving start-stop system, EPB digital intelligent electronic parking system, and Configurable color-customizable digital instrument system.
I've been driving a Roewe 550 for several years and have encountered the issue of the car remaining powered after removing the key multiple times. Most cases involve the delayed power-off function being active—some models allow certain circuits to remain powered for 10 minutes after removing the key to prevent situations like forgetting to turn off the lights. This feature is useful, but accidental activation can drain the battery. It could also be a faulty ignition switch, where internal contacts get stuck and fail to disconnect the circuit; or a blown fuse causing system failure. Another possibility is a bug in the control module, such as a malfunctioning BCM (Body Control Module), which can cause the circuits to misbehave. I recommend first trying to disable the delayed function by adjusting the settings in the car's menu. If that doesn't work, visit a repair shop promptly to check the switch and wiring. Don't delay, as it could risk battery failure or even a fire hazard.
This issue is quite common on the Roewe 550. I think the main root cause lies in the electrical system malfunction. For example, my own car once had the cigarette lighter still powered after removing the key. After troubleshooting, it turned out to be a worn ignition lock cylinder – metal parts develop poor contact after prolonged use, failing to completely cut off the power. It could also be due to some modules' delayed sleep mode, where the car doesn't shut down immediately, causing the screen or audio system to remain active. A simple check of the fuse box to see if the corresponding marked fuse is blown might solve the problem if replaced. For older vehicles, aged wiring or short circuits could also be the culprits. In any case, don't ignore it; the safest approach is to promptly visit a 4S shop to read the fault codes, preventing potential breakdowns on the road. Safety first, after all.
The issue of the Roewe 550 remaining powered after removing the key is mostly caused by delayed power-off or switch failure. Delayed power-off is a designed feature that keeps the circuit powered for a short time, allowing you to close windows, etc. However, if it doesn't turn off at all, it might be due to incorrect settings or module conflicts. A faulty switch—where the ignition contacts stick—can cause continuous current flow. Sometimes, a blown fuse can also lead to signal confusion. The simplest solution is to restart the system: disconnect the battery for a few minutes and then reconnect it. If that doesn't work, have a technician check if the control module needs a software update. Avoid letting electrical components drain power unnecessarily, as it can damage the battery.
