I purchased the S-VCM Controller in early January 2020, before leaving on a trip from Pennsylvania to Arizona for my 2012 Honda Pilot. It worked fine going across the country but yesterday my temp gauge has dropped to the lowest cold reading while driving at 40 mph with the outside air temp in the low 70's. It eventually returned to a normal reading but today while driving back to Tucson the gauge again dropped to the lowest level (where the needle would be with the key removed from the ignition) and stayed there for the entire trip home, about 45 minutes. The outside temperature in Tucson this past week has averaged in the low 70's. Has anybody ever had this happen to them with this controller or any other similar device?
