I think we call it a known issue, but GM isn't too keen on addressing it. 
I rant, occassionally, about "old think" in GM's approach to cars. Especially in the leading edge Volt! I think the navgation is great for 2002, but it won't ever get a software upgrade due to productizing around model year. Teslas get OTA upgrades. They aren't held back by old paradigms of doing business.
My particular beef is when street names, for the street you need, won't show up no matter what zoom level you try. Just have to drive a half mile on and try again. And then usually you can make it work at a random zoom level. I use my Android phone for addresses not in my car address book, that I go to in familiar ways and want more than a miles-to-destination estimate.
