I was driving my 2015 S around Highway 101 near Broadway, in Burlingame, CA today and noticed that the GPS map does not correspond with the new actual upgraded exit/entrance ramps to the highway. Anyone know how often Tesla updates the GPS/maps?
About once a year. And then those maps are about a year old. (So your maps go from being one to almost 2 years old.)
However, Tesla is supposed to start rolling out a new navigation system this weekend, and the plan is that the maps will get updated much more often. (It is rumored that the initial maps will be dated January, 2018.)
The vehicles have onboard navigation maps covering huge areas (such as all of North America) - updating this data takes gigabytes of data, making it impractical for Tesla to frequently update this information - so Tesla appears to be updating the onboard map data every 12 to 24 months - which means that recent or current construction likely isn't included in the onboard map.
Can you tell us what version of the maps you have installed in your Tesla? Go into the Software tab on the Control Panel, and you'll see the version of both your TeslaOS and the Navigation Data.
