It opened once while in drive and stopped at a traffic light. I hadn't figured out that the driver door hatch switch will close it if you hold it up for a few seconds. I had to find a way off the road so I could stop, get out and close the hatch. It's getting annoying to go outside on my way to work and see the hatch open. I've also been shopping at the mall, came out and there it is, wide open. Fortunately nothing has been stolen yet but it's only a matter of time. Is anyone aware of a way to disable the key fob button for opening the hatch? I have no where else to carry my keys. I've checked the vehicle settings but found no way to isolate the rear hatch from the key fob button. VERY annoyed with this!
If you purchase the BMW key fob case, using it, you'll be able to prevent the buttons on the fob from being depressed while in your pocket. (This is based on my own experience.)
However, I think you'll find that the problem is not being caused (for the most part) due to the buttons on the fob being depressed. The issue is with the optical sensor - which BMW has acknowledged is hyper sensitive. I believe there is a fix for it...

Thanks RidinDirty. I had read the service bulletin and I'm more convinced in my case that it's the button being unintentionally depressed while in my pocket rather than an over sensitive smart opener sensor. There's nothing behind my car in my driveway and possibly cars going by too close in a mall parking lot with me now where near shouldn't cause it to open. I suppose a key fob case is the answer to my issue. I've had Z4's, 230s, M240 and a 440 without having this issue. I think I will take it over to the performance center and let them change out the smart opener sensor since it costs me nothing other than time out of my day. As we say in the south; thanks y'all.

If you are referring to the hands free operation, the tail gate sensor only work if the fob is close by like less than 1-2 feet. I have verified that if you placed the fob in the rear passenger seat, and then go outside to wave your feet below the rear bumper, the tail gate won't open. So, in most cases, the tail gate open is because the fob was unintentionally depressed by an object. Now, I removed all my other keys to a different key chain and leave the fob alone, and put them in separate pockets. Since then, I never experience the problem again. Hope this will help.

Test drove the new X3 recently - as demonstrated by my sales manager, tail-gate sensor works only if key fob is within 3 feet of sensor.

This is driving me nuts! I walked out of Home Depot yesterday and the rear hatch was open with my briefcase (with my laptop inside) was sitting there for anyone to take. Then last night I went out to the garage and the hatch was open again. I had parked a couple inches to the right, the hatch would have hit the bar coming down from the garage door opener and would have likely damaged the car. I had the same issue on my 2014 Chevy SS and they reprogrammed the system so that you had to hold the button down for three seconds. However, when you had tighter fitting pants on, the three second delay did not work. A couple of times I came out to find my trunk open while it was pouring rain.

Try to remove everything attached to your key fob, and make sure no other object can pinch the key fob and you will be OK. I have been doing it for almost a year and never had the tailgate open again by itself:-)

My husband no longer leaves the key in his pocket. That seemed to fix the problem for us.

In theory, a reasonable recommendation to make - but actually never addressed the problem for me. The BMW fob cover made no difference. BMW had no solution - other than to disable the functionality altogether.

Yeah, i have this problem too on my G01 X3. In fact I just dented the liftgate when it opened while in the garage and I opened the garage door without noticing it was open a few inches and pressed against the garage door. Then, the other day I went somewhere and when I walked out to the parking lot, the lift gate was fully open. I just ordered the below key fob cover to hopefully help. Both times it opened, the fob was in my pocket with other keys and stuff. I've also set off the alarm in my garage too so I'm pretty sure the buttons are just getting pressed. Hopefully this solves it.

BTW, if someone actually gets BMW to cover the repair of the lift gate, I'd love to know as that would be amazing. But I'm not terribly hopeful. Dented the lift gate and didn't even have 1000 miles on the car yet. Grr....

We were lucky as it only chipped the paint and no dents. Had it repaired and you would never know. My husband just bought a key fob cover from the dealer when we were in Denver.

Hopefully, it will fix the problem for you, but note that the material is fairly thin and flexible. If your pockets are tight, I wouldn't expect it to help much. You can still squeeze the middle and open the hatch. It's better than nothing, though.

The BMW cover is a lot stiffer and prevents button presses better, but a good squeeze in the right place can still open the hatch. It's also very thick (like 1" thick).

(I have both, and ended up using the BMW one, even though it's almost absurdly thick.)

I've been having the same problem finding the rear hatch open on occasion and just the other day while opening the garage door the hatch must have somehow opened during the previous evening. A small amount of paint scrape on the edge but no dents or dings. For this key fob controller what a piece if shiite design by the BMW engineers. We've had numerous minivans all with sliding doors and rear hatches and none of those no matter where the keys were placed ever inadvertently opened the doors.

A key fob case never solved the problem for me; I ended up just disconnecting the module behind the rear bumper. Although, I read on this forum that this "feature" can be coded out.

Mine even activates the Comfort Access option when hand washing by locking/unlocking the doors whenever a stream of water from the hose plays across the door handle(s).

That's normal across many brands, not just BMW.

Might be, but it doesn't make it any more acceptable.
