You can no longer get Supercharging miles from your referrals of Tesla's vehicles and solar panels. A notice on the company's site states: "vehicle products and solar panels are no longer eligible for Referral awards" as of September 18. The only active referral program is for the Solar Roof, which gives referrers monetary rewards of up to US$500 and free Powerwalls.
With these programs axed, it isn't clear if the company will fulfill some of its bigger promises to referrers. Those promised Roadsters still haven't gotten them, and people have been complaining in online forums about not receiving free Powerwalls and other rewards from years ago.
