I'm one of the ones who was complaining about this issue last winter (and I believe I mentioned it in a service request).
What We've noticed:
- It happens in winter, not in summer.
- Seems to happen more often at night.
- It seems to be more likely to happen after failures of homelink to open the garage, which usually happens when our outdoor lights are on, which is usually at night time. Last winter I often had to turn off the outdoor lights (using the voice assist) to get homelink to work.
- However it still often happens even when homelink works first time.
- The last couple of weeks I've been able to reliably reproduce it about 80% of the time. I arrive home, use the car homelink to open the garage, drive in, get out, shut doors, walk down the driveway to the mailbox, walk back to the car, homelink triggers as soon as the car wakes up. Last night I decided to take a video given that I seem to be able to reproduce it fairly reliably.
- Doesn't seem to depend on what other cars are home.
I've shared the full video on swfeedback.
Attached is a low resolution 4x speed video to fit in the file limits in this forum.
I know that a couple of years ago Rivian had a similar issue where it would sometimes operate homelink when the car wakes up.
