I just got back from a trip to Toronto where I was trying to supercharge at the Sherway Gardens/Etobicoke supercharger. Plug in the car, cord doesn't seem to go all the way in, screen alerts say charging rate reduced, re-insert charge cable, something to that effect. Light is orange on the charge port, and no charging is happening. See a whole bunch of people pull into supercharger spots, try, and then move to another supercharger spot. Some leave in frustration, others keep trying different spots. I called Tesla support, because I've got a 200km trip to get back home, and I've got 100km of range left in the car (which is worth about 50km in real usage). Guy on the phone thinks it's something to do with my car, try power cycles, resets, trunk cord pull to no avail. Then I take a closer look at the supercharger plug, and notice that it looks like there's some ice stuck inside the port preventing the plug from going fully in. Check all of the un-used chargers (and try one other) and they all have various degrees of ice in the supercharger plug. Eventually see someone leaving after charging, and am able to plug in a "clean" supercharger plug into my car and all is well. During all of this, I notice that some of the supercharger cables are left hanging on the floor, others won't actually holster back into their holder. I think ultimately Tesla needs a better design for the plug holder, because it is quite flimsy and easily falls out (especially in the bitter cold). once you've got ice in the plug, I don't know how you'd get it out until the weather warms over freezing (I'm not sticking anything into that plug!!).
So just a PSA for all the Canadians who can't seem to get the supercharger to latch, it may not be your car, it may be the plug itself. Also try extra hard to make sure the plug is re-latched when you're done (but I honestly think this is a design issue, not a user issue). Saw one or two others struggling after I figured it out, tried to pass on the wisdom (after about 40min of phone calls/fiddling with supercharger plugs). Also, the supercharger rate appears to be permanently stuck on the high 49c/min rate for some reason... guess that's my thanks for figuring out why the superchargers don't work. I should charge Tesla a consulting fee hahahaha
