If you're looking in the Acknowledgements tab, that isn't customer emails and names, nor is it a bug.
These are individual acknowledgements of different software developers, github repositories and packages that Tesla is giving credit for using in their app.
You'll notice each of the entries generally includes the name of the software package/library/tool/etc, followed by their name, email address or website link.
This is an intentional "feature" of the app to credit those authors with their work, and has been in the Tesla app for a long time.
There's no "security risk" or anything here, this isn't confidential data or anything that violates CCPA. You don't need to bother contacting Tesla or reporting a bug unless somehow your Acknowledgements page isn't the same as everybody else's - maybe you can look up some images online of what the feature is supposed to look like - it's intentionally designed that way, and using a font that "looks" like code might. Overall it's a neat easter egg as a nod to the developers, and not much more.
