I started to complete the online form. Then I stopped.
Four things raised flags for me.
1. There was at least one, maybe two, redirects. I would think that if Tesla was contacting me, it would do so by sending me to a page directly, not with redirections.
2. The redirections ended at a non-Tesla URL. If it were legitimate, why was I not landing on a Tesla page?
3. Tesla already has most of the information that the form requested, such as name, address, etc. Why would Tesla be asking me for information I have already given them?
4. Every Tesla owner has a Tesla app on a device. I would think that if it were a legitimate Tesla communication that it would come as some notification on the app.
