I'm getting frequent inaccurate location as the same location, can I make this stop? My wife and I are both having this occur frequently, with the primary issue it brings up being that we often find ourselves getting directions to our desired location or searches for things nearby oriented in Mascoutah, IL when we are in fact about 45 miles away from there. 

I have an LG G3 running Android 5.0 and she has an LG G4 running Android 5.0. 

I'd like to figure out how to make this stop occurring, or at least occur significantly less.  I would have blamed WiFi locations, but I'm including a few screenshots of three different days of mine that show it is very unlikely I'm hitting a WiFi consistently with that location.
When this occurs, send feedback to Google from Google Maps, with your location enabled. 


Open Google Maps.
Touch the menu (three lines).
Touch 'Send feedback'. 
Touch 'Report location issues'. 


This is what Google requests that you do. 

More background:

The Washington Post reports that location as reported by your cellular provider can be inaccurate. This story includes a successful resolution for one person from Sprint, but a continuing battle for another person. Part of the trouble is that no one owns this problem. Reporting it to Google is a start, but may not actually solve your problem. 

It could also be a WiFi problem. Using alternate firmware like DD-WRT often resets the MAC and SSID to a common default; so it is definitely possible that there are access points at multiple, widely spaced locations that map to the same place. 

If you have the location accuracy of the bad location, this may also be hint as to the error source. WiFi will generally report errors in the 10s of meters, while cellular is generally in 100s of meters.
