oops, my bad. I don't have the HQ, I have the original one as shown in your first photo. Have you also experienced this charge port problem?
My wifi is spotty at the Blink, so I easily could have missed a firmware update.
I personally have not as I have a Clipper Creek unit, but I have heard about it through MyNissanLeaf forums. The pre-2013 Leafs only charged at 3.8 kW so it wasn't a problem, but another member who went with a Tesla-powered RAV4 EV (which charges even higher than 30 amps) said that his charging handle actually melted.
This is one of the early incidents in 2012 shortly after the RAV4 EV came out. There are some nice pictures in the thread below.
Toyota paid to replace his charge port.
