As a Tesla owner of 5 years with a cross country road trip in the car, Teslas charging has never failed me. It’s rare to encounter a charging stall not working, but every location has multiple chargers and they repair stalls quickly.

Almost every location I’ve been to has at least 8 stalls if not more. The navigation in the car also keeps track of stalls in use, electricity prices, expected wait time and if any stalls are not working.
