I've had a really alarming issue in my local Cleanfreak car wash on 2 separate occasions. I have a 2015 P85D and when I take it to the carwash the following happens. About 3/4 of the way through the carwash the car goes into park and gives me a "check charge port" warning. From what I can tell, the brush from the carwash hits the charge port and signals it to open, to which the car responds by immediately shifting into park and stopping in the middle of the wash. I can't put it in neutral or drive until I actually get out and close the charge port, which, if you've never gotten out of your car in the middle of a car wash, really stinks.

I couldn't find any other descriptions of this issue, so I thought it was a freak thing, and tried the car wash again. Same exact thing happened (the second time I had it in tow mode, made no difference).

Has this happened to anyone else?
Does anyone know of a way to disable the charge port from opening?
I know that tesla recommends against automatic carwashes. Could this be why?
