How to Solve the Issue of BMW Trunk Opening Automatically?
2 Answers
It may be due to a stuck or adhered trunk switch button or other hardware issues. Below are relevant extended information: 1. Trunk switch button stuck or adhered: There are various buttons on the key, such as on the remote key, near the steering wheel, and on the trunk switch. If any button gets stuck or adhered, it can cause the trunk control program to receive incorrect commands, keeping the trunk lift motor in continuous operation. Solution: Have it checked at a 4S shop. 2. Other hardware failures: For example, the trunk module itself may be faulty, or there could be a lock block failure. Solution: After ruling out possible user errors, initialize the trunk program. If the issue persists, seek professional repair services.
I had this issue before with my old BMW—the trunk would open by itself out of nowhere, which really freaked me out. Thought it was haunted! Later, I looked into it and realized the key in my pocket was getting pressed by something. Now I’ve learned my lesson: keep the key separate, not in a bag where heavy items might squeeze it. Also, you could try resetting the remote’s battery or checking if there’s a software update in the BMW app—many newer cars have this issue due to system bugs. If that doesn’t work, head to the dealership ASAP to check the sensors or locking mechanism. Don’t delay, or you might risk losing stuff or even the car itself. A friend’s car had the same problem, and after fixing it, things got much better—way less hassle. Just remember to check the trunk’s status before driving.
