Not all, but certainly a more than just a few. At the time, our guess was probably because of the tropical storm that passed through the NYC / southern NJ area. But apparently it was the ongoing software updates on specific Phase I stations (article from June 2019).@Lumas - Good idea to call EA support team to make sure chargers are in working order. I did read an article that stated all EA chargers were shut down on the east coast corridor with no advance notice leaving a lot of EV owners stranded. I think I'll follow yours and @omegafiler set up in the car regarding navigation set up using Android. The plan is not to go below 20% on the road unless I'm close to my home, and to only use the 150 kw chargers.
In the NY/NJ area, IMO, EA is probably still the most reliable equipment/network offering ~150kW charging. Hopefully, the dealership extends that complimentary 1000kW from EA and you can try out their stations. I'm curious to see what your thoughts are on EA.
