Tesla has been phasing out free unlimited access to its network of fast-chargers for a couple of years now. The last vestige of that program was a referral system that was supposed to expire at midnight Sunday. But it’s been given new life for at least one more day, and perhaps even longer to buyers in Europe.

On Monday, Tesla CEO Elon Musk announced via Twitter that the referral program would be extended until Tuesday night after customers reported technical problems. The extension is just for new Model S, Model X and Model 3 Performance buyers who receive a referral from an existing owner.
