How do I report slow or non charging stations?

I believe there's a telephone number to call on the superchargers themselves. Before you do, realize that it's cold out there and that slows charge times. Also, as I recall, the stations in Quartzsite are not arranged normally as 1A, 1B, 2A, 2B... but rather 1A, 1B, 1C... 2A, 2B, 2C... So pay extra attention that you are not sharing a number if possible.

You can also call the customer support number on your mileage screen in the car
