That was a problem, but most EA chargers I've used since I bought the car have been reliable. The exception was at locations with physically broken connectors. They show up in apps as available, people go to that location thinking that there's no crowd, and there ends up being a long line. I don't know whether people are not reporting them or EA is not flagging them when reported.
A bigger problem as I see it is that EA decided to have far more locations, but with few chargers per location. That makes it impossible to plan a route and select EA chargers along the way and have any expectation that the availability you see in the app will have anything to do with what will be the case when you get there. And one charger down in a location that has four is a significant problem.
Tesla has fewer locations, but might have 100 chargers at a given freeway exit. So if it comes down to driving from one EA location to another, giving up and waiting in line for an hour, then a Supercharger will be faster. Plus, by not waiting around for someone to leave, you can go eat and come back when the car is charged.
Tesla is far from ideal.
