Is there not a way to just code this off with the i-drive? Or must it go to the dealer.

I had a short local driving before entering the highway. About 5 mins in the highway, the trunk just opened by itself. The car feels very noisy and hard to control (i was on a windy highway).

Fortunately, I did not have anything in the truck, otherwise they may just fall off and hit the car behind me! I existed the highway, stopped on a local street and closed the trunk.

This random opening also happened once in my garage (the car was parked and locked) one week ago.

With two random opening happened in one week, I am afraid of driving it. You never know when it will suddenly open again.

BMW, you need to fix this! I have drove several SUVs and never had this problem before!

Update 2/23. Today I test it and now know the reason. I let my wife slowly drive the car forward with all the doors locked. I use the kick open feature behind the car. The hatch opened, while the car is moving! I also have the key fob in my pocket. Did not test it without the key fob. So definitely, the hatch may open while the car is moving!

I guess, on the highway, some small rocks triggered the kick open sensor and once triggered, it will open the car no matter the car is moving or not!

Same here: happened to me couple of times - service did not find anything!
Check your key fob in the pocket, considering to put leather case on it (very sensitive buttons? Or real problem?)

The comfort access kick function requires the person to be at the rear of the vehicle with the key fob on them in close proximity to the rear of the vehicle. If the key is not detected near the rear of the vehicle then the kick function should not operate. The trunk would likely have opened some other way.

Totally, I’m glad I haven’t ordered mine with the kick sensor comfort opening. Anyone had the boot open on a vehicle without the comfort access?

I’ve just swapped from an X3 without comfort access to an m40i with it ,so I’m re visiting this thread but no updates for a while .
I had no issues before so I’m going to check mine again while on the move

My trunk won't open unless I'm at the back (like it should be) with the kick function. Kids tried to open the trunk while i was only at the side of the locked X3.

The trunk should not open when the car is over 0 mph period.
You guys are putting so much effort into testing for bmw which should be an easy problem for them to solve.

Update 12/10. Today I got contacted by National Highway Traffic Safety Administration. They are investigating the issue because several people have reported similar incidences to them. They also mentioned that BMW offered a software update recently that will prevent the tailgate to open when the car is moving above certain speed. My car was serviced two months ago and the dealer did mention that there was a required software update. If you experienced the same issue, please ask your dealer to do the update. Also report to NHTSA.

Dan_80 The NHTSA also contacted me today. They found my videos on YouTube showing the tailgate unexpectedly opening.

• Video 1.
• Video 2.

The software updates for the tailgate opening unexpectedly are covered by:

• TSB SIB 513016 / NHTSA ID: 10136344
• TSB SIB 662317 / NHTSA ID: 10135050

I will check with my dealer to see if my car needs the software updates in those TSBs.

I haven't experienced any recent problems with the tailgate opening because I had the dealership disable the kick-to-open sensor. I am going to ask them to install the software updates and enable the KTO sensor.

We've just bought a 2020 plate BMW X3 with the power tailgate. While parking at work today, the boot opened while i was reversing into a space and only stopped itself when it hit a wall. Considering i've only had it 4 days and now the boot door is all scratched i'm not incredibly happy... There didn't seem to be any way for me to stop it from the drivers seat when it started to open. I've made an appointment with the BMW dealership to have it back and wondered if anyone else had any issues with the dealerships fixing it under warranty? Any pointers would be greatly appreciated.

Sorry to hear that! I wonder if you tried closing the trunk by pulling the trunk door button by the driver door.

I've never experienced that problem but I always park at least the 1st green distance indicator (looking at the rear camera while parking) away from the wall or any other obstacle. By doing that if the car decides to open the trunk door on its own at least the door won't hit anything.

I 've observed the same phenomenon. The rear opened on its own twice, once while parked overnight. I am pretty sure I did not press the fob.

Another issue is the intermittent functionality of Comfort Access. The door would not unlock when I am pressing the handle groove.

I don't care about the door, but the spontaneous opening of the hatch is a concern. Difficult to troubleshoot, if the electronics malfunctions intermittently.

Hi,
Pressing the door handle groove - on inside edge of handle is only for locking.
Just pull on door handle to unlock and open the door with comfort access.
