Your Tesla vehicle may have come with free unlimited Supercharging that is transferable to a future owner if you decide to sell the car if it was acquired before a specific date in 2017. However, it's unlikely that the car will have a Tesla free Supercharging transfer if you bought it after that date or if you bought a used Tesla. You can check the vehicle's manual or get in touch with Tesla customer care to find out if your Tesla has a transferable free unlimited Supercharging promotion. In addition, to view any available Supercharging credits or promotions for the vehicle, simply navigate to the "free Supercharging" menu on the touchscreen. In any case, when selling a Tesla, it's critical to be open and honest with prospective purchasers regarding the vehicle's free Tesla Supercharging status, as this can have a big impact on the car's attraction and value.
