    I've searched through a few threads, but one was linked to a bad trunk latch and one was linked to lights not being connected. That's not my issue. It's also not a case of the lights being dim.

    If I approach the car from the rear and open the trunk during a time when the car has been sleeping, the lights in the trunk don't turn on. If I wake the car by at least partially pressing on a door handle (the same thing I do to wake the car to allow me to disconnect the charging cable), and then open the trunk, the lights do turn on.

    I don't remember the car always behaving this way, but maybe I just wasn't paying attention before. Anyone else see this, and is it something that you remember being an issue for some time? Is this somehow linked to a software update?

    i'll have to check this out in the morning next time. the lighting in my garage is usually so that I don't need them anyway. i assume you've stuck your head inside and verified that no lights are on?

    I had a problem where one of the lights wasn't turning on randomly and mobile service came out to look at it - of course it was working when they showed up. They swapped the left and right trunk LED lights and they were still both working. The tech said he'd request some remote diagnostics and someone would get back to me. Well no one got back to me but I also haven't seen the problem come back.

    I realize that doesn't help you out much, just sharing my experience.

    Dark garage, or dark at night when returning to the car. If I open the trunk before doing something else like moving a door handle, I don't seem to see the trunk lights turn on. They're easy to see when they're on, and obviously not coming on when I'm loading the trunk in the dark outside. It's odd.

    i wonder if they're somehow connected to the ambient lighting profile. like when my SR+ suddenly had every light on the inside of the vehicle illuminate, even though they don't work on a normal basis. if the trunk is somehow set up in a "partial" profile, maybe it's not getting activated while the car is sleeping?

    I have the ambient lighting turned off, but that could be something to try. I'm more inclined to think that opening the trunk is one of the odd things that should wake the car that doesn't completely wake the car. It does allow me to remove the charge cable.

    My 13 year old was actually the one who found the pattern for me. I thought there was just something wrong with the lights, but he was able to tell me when they worked and when they didn't. Good think I make him load his own backpack and saxophone in the morning.

    The stock bulbs are so damned dim it's hard to tell if they're on or not. First thing I changed out on my car.

    Even if dim, there's a clear distinction between some light and no light. I'm looking to see if anyone else is seeing cases of no light when their car is waking up/still asleep with the trunk open.
