Just to clarify, two things.
Just to clarify, two things. First, the vast majority of Model S owners use the UMC to charge and don't own HPWCs. In fact, Tesla doesn't really recommend getting the HPWCs unless you regularly have the need to charge at faster than 30 miles per hour. Second, Tesla proved that the UMC wasn't to blame by pulling the logs from the car showing there was no variance in charging to the point the fire started. The problem was at the plug along which easily spread to boxes that were stacked near the plug. You can believe Tesla or not, but no further investigation is being done by either the fire investigators or Tesla at this point. The case is closed.
