Is there a fix? Manufacturer service bulletins
The manufacturer has issued service bulletins covering body on this vehicle — documented repair instructions, service campaigns, or warranty extensions sent to dealers. A TSB isn't a recall (it's not a free safety remedy), but it's the manufacturer acknowledging the issue and how to fix it.

What owners are reporting 2 most recent
On 7/25/2023, I left my car keys inside the trunk. The 2015 BMW 320i xDrive does not have access from the cabin passenger to the trunk to open manually. Even the locksmith cannot open it. This is the bad design and may create safety issue. I called BMW road assistance and they cant help me instead told me to tow my car to dealership.
Can NHTSA enforce a recall on the well-known 'trunk opens on its own' defect on BMW 3 series, which my 2015 320i also has since I bought it in 2016? Please see attached 'to NHTSA on BMW series 3 defect.pdf'.
