I also experienced the issue of the trunk opening automatically with my X3, which was quite alarming. That time, when I parked at the mall, the trunk inexplicably opened on its own, and items inside were almost stolen. After troubleshooting, I found it was a problem with the remote key—either the battery was weak or the switch was accidentally pressed. Replacing the coin battery fixed the issue. If the battery isn’t the problem, check if the trunk switch is stuck or if dust has entered, causing accidental signal activation. Additionally, dirty vehicle sensors might trigger this malfunction—try cleaning the dust around the trunk area. If the issue persists, it could be due to a control module or wiring short circuit; an OBD tool can help read error codes to diagnose the cause. Safety first—an unintended trunk opening not only risks theft but also increases hazards while driving. It’s best to address it promptly and seek professional repair at a service center to avoid greater losses.
