FWIW all my Honda Link features work as they’re supposed to. The odo always reflects what the car has every time I turn it off. The find my car has always worked as long as my phone has internet access and the car has reception from the GPS satellites and has cell signal to find the HL server.
So it is possible to have it work w 100% functionality.
Remember, this is a free service and Honda is paying for all those packet data transmissions. I notice that my updates while charging are not real time but occur every 1 to 2 hours.
If yours is not updating, may I suggest checking the TCU signal displayed at shut down. And maybe delete and reinstall HL app. Make sure you’ve got the right HL app, there are several different ones available as I recall. Maybe even try the reset by disconnecting battery. And if all else fails take it to the dealer; they know everything about it. (Insert miniacal laughter here)
