I have this problem too...even if I don't have android auto started if im in the car google maps keeps starting with no way for me to disable it. Its driving me crazy!

When I start my car I want Spotify to open in fullscreen, I don't need navigation for my commute. This is an extremely infuriating UX fail

I also wish this could be customizable. I honestly do not need Google Maps to open after plugging my phone in. Why do they think they know what we want?

Yea its eating up my data I'm going to see if i uninstall maps if it helps

Have this problem since the last update. Anyone know the option to disable?

Same here. Hella annoying

Same here, pissing me off. How do we stop it from starting

Same here.... Started with the last Android update.... Very annoying.... Suggestions welcome!

Same here. While I can afford the data, I cannot afford the battery drain.

The best way to stop most Google Apps like Maps starting and running automatically on an Android phone is to disable them. Go to 'manage Apps' and scroll down and press on Maps - then press disable. Problem is of course if too many do this then Google will remove the disable function on their Android system. But for noiw it works - do the same when you need to enable it.  Google makes money by selling information about users of its Android System and Google Apps - same for Facebook and Twitter and all others - that is the price we pay for using them - no free lunches/Apps.  Hate to say it, but Apple is far better at all that privacy and information marketing- but they cost far too much.
