i did find a thread on it so it seems to be common and prob to be cleaned up in futire updates. although i do enjoy looking at my truck often, i have not sat focused on those two lights long enough to see a pattern or if it does it when key fob in proximity.
No, it is not "waking up". I go in and out of my garage all the time without my phone or key fob. The truck does not wake up. It almost seems that it is on some sort of timer (like an old vintage alarm system). My kids have seen it too.
This might be a glitch in the software as this never happened as recent as 2 updates ago.
My fob is hanging on a hook a long way from the (detached) garage. I have proximity turned off "at home". I've noticed this when walking past with my phone in my pocket. My "card" is in an RFID-proof Ridge Wallet in my pocket. Still happens, but not every time.
