The keys are original.
In that case, good luck pleading your case with the dealer...

There's a service information bulletin on this concern

Thanks. I'll tell my father to bring that to their attention. They actually claimed that they have never heard of self opening trunks and windows in any BMW.

SIB just came out last month, just stumbled across this old thread. Fix is a remote programming session to be done by BMWNA.

Thanks! I let him know and gave him the key phrase "remote programming".

As of last week, Dad's car had been at the dealer for a week with no end in sight. He took it in for the programming as described above. The delay was a battery diagnosed as bad and they were waiting on a replacement under warranty.

Annual lithium battery replacement at $1000+ is going to hurt when the car is outside the warranty.



EDIT:
The trunk of his loaner F30 320i popped while the key was hung on hook in the kitchen last week. Key location was verified by my mother when my father discovered the open trunk. A couple weeks ago, my father talked to a 435i owner at a gas station while fueling up his M3. When my father mentioned the autonomous trunk shenanigans, the 435i owner said his trunk opened itself a couple times as well.

Lithium Battery? I thought the normal battery was AGM. Expensive but no where near $1000. Hybrid or full electric would be lithium, but that still would not be the battery that operates the car electronics, just the electric drive system.

It has a lithium starting battery, probably lithium iron phosphate (LiFePO4) rather than lithium ion. LiFePO4 is is heavier than lithium ion but is much less explodey.

EDIT: It might be lithium ion.

I stand corrected on the battery. Guess it has to do with the auto stop/start functionality. But as this was working perfectly fine with AGM, what is BMW thinking when using such an expensive battery? If it lasts 10 years it might make sense, but that does not sound like the case.

The car is STILL waiting at the dealer for the lithium battery to arrive. These lithium batteries check all the wrong boxes to save those 30lbs.
- unreliable
- expensive
- long lead time for proprietary spares

Perhaps one of the curious and resourceful technicians around here can poke around in the programming options to see if an AGM battery can be selected for the F80/F82.

Same car, same problem, the trunk still occasionally opens by itself

Are there any updates for this problem?


The good news is that his carbon roof F80 now has roof rack capability.

2+ years of random unattended trunk popping and no fix is in sight. He was reluctant to lemon law the car and now he cannot because his state has a 2 year limit. He still has to hit the trunk lockout switch in the glovebox whenever the car is parked outside (basically anywhere he goes). Unfortunately, it sounds like he has basically accepted living with it so I don't think he will attempt any more troubleshooting. When I get my hand on the car in a year or five, there will be an update.
