WTF? Trunk opened by itself?

Yea, dealer was confused. What bothers me however is that this fix only helps if the car is locked. If the car is unlocked, like it is my garage, then it is still a single push of the trunk button. Might have to have it officially coded for a double press.

Lock the car in garage, problem solved

That would be a royal pain in the ass and something I've never done - nor had to, because my trunk never opened on its own.

Pain in the ass to touch the door handle which takes less than a sec ??
Moreover it's always good practice to lock car always

Only if I have the key with me -rarely do it - stays in the house. The pain is when going in and out to the car to get something out of it - and now, having to remember that IF I decide to keep the key on me, the trunk could still open.

And for those of you thinking about doing this update from the dealer, do note that my car has been returned as new - not one saved setting remains including seat memory, M buttons, short cuts, etc. Like a brand new car.

Chit.

Correct the software update removed all personal settings and i was pissed too as i thought the update will only be for the remote and SA was not aware of it until they made the update and i lost all settings

First I have never had the trunk open by itself on my 2016, coming up on 2 years in May, so not sure exactly what changed.

Second I always lock the car in the garage. I was told by dealer the electronics do not go into full sleep mode if it is not locked. So there is more drain on the battery.

It's probably because you pressed the button on the key by accident.

On the plus side, my iDrive now talks as a lady with an accent! Love it. Didn't know this was changeable!

I never had my trunk open in all of my years of driving BMWs. My M2 had the same remote as the M3 and my 650GC had the same remote, albeit heavier. There is something with the M3/3-series that is making this much easier to do (as witnessed by this thread).

Locking the door will put the car to sleep faster - for instance if you only do the one push, then it will shut it down. Worst case, the car stays alive for no more than 15 minutes after shut off and with the lithium ion battery in this car, there should not be a need to "lock it" to make it go to sleep faster.

I don't think anyone disagree with this - the mystery is why does it happen so easily with the M3/3-series key/software vs. other BMWs. As noted, been driving BMWs for a long time (continuously since 1995, with the exception of the dark Lexus period of 2001-2004, but we shant talk about that). Never has the trunk opened on me - with key in pocket.

Happens to me all the time. Super frustrating when you get out of the car and are running to the train.

I took mine to the dealer for a service and mentioned this issue. My advisor had the mechanic code my fob (two clicks to open trunk) and disable the kick swipe feature under the bumper. I have not had an issue since. According to my advisor it's a known issue so just take your car down to the dealer and have the code it.

[Evren]

very interesting. i have never seen this on my car.

[hyperspeed]

Shit keeps happening to me. It's so damn annoying. There's no way I'm triggering the key fob but the trunk has been opening once every 2 weeks or so. AT work!

While there was no way I was pushing the button, it was ONLY happening with the key in my pocket....

And as noted, it never happened with my previous cars...

[LucasElectrics]

Very interesting thread. I have had the trunk lid open problem several times, and driver's window open once. Took my car into my dealer this AM, and here is what I got back:

Connected battery charger, ran ISTA test, checked air for PUMA measures, found measure 63379954-06. Part backordered Germany.

PUMA is their name for a database of issues that various dealers around the world have resolved. Not sure what the part will be, except that it's electronic (surprise, surprise). I'm very curious how this will play out.

BTW, I am aware of the coding workaround. I am assuming I can do this myself with my copy of BimmerCode, but I don't really like that so-called solution.

[snareman]

It's odd that I'm on my 5th BMW and haven't had this problem on any of my previous ones. I'm going to try setting the fob delay to 3 or 5 seconds for now and see if I can get to the dealer to get the TSB done. Thankfully I don't usually have too much in my trunk, although sometimes I have a gun or two back there and I'd prefer to not have those stolen.

[instarand]

This has happened to me twice in the 5 weeks I've owned my '18 F80. It could have been the key fob in my pocket, but I didn't think that was the case.

Speaking about the trunk opening, does pressing the trunk release from driver's seat or the button make the trunk just un-latch or is it supposed to actually open? Mine only unlatches.

Open completely. You need to move the trunk springs to position 2 or 3.

I just saw the trunk was opened again. I get to the car, close the trunk . And I just get far away the car use key to lock the car. The car has been locked. That's so strange. It's kind of automatic open trunk. And my key are secured after first time. Anyone has same experience?

My trunk opened like 20times the keyfob in my pocket opens the trunk.
I just started to lock it in the glovebox with the switch

[paliknight]

So this was an issue for me constantly happening with my F82. When I got my F80 recently I bought one of those key covers. I tried pressing the trunk button thru the cover by applying pressure to confirm there is no way for it to press the trunk release button in my pocket. One day I took the key out of my pocket (while still in the key cover) and the trunk randomly popped open. It was very strange since the key was still in the key cover and I hadn't pressed any buttons nor was I close to the trunk to kick it open.

[Wah]

This happens to me occasionally... it happened on my 2015, and also happens on my 2018. It happens more frequently on my 2018. I run an RKP diffuser... I don't know if that has anything to do with it. I look like an idiot trying to close my trunk as it keeps popping open as if I left my keys in it. So dumb lol...
