Hi all, We got our 2018 Clarity Plug in Hybrid since October with no problems until today. I stopped to fill up the gas tank and when I got in and started it the gas gauge didn't go up to the full mark. After a few moments it crept up to the top a little at a time. Problem is the range number didn't go up. So now I have a fully charged and gassed up car that says I only have a 256 mile range. I know it should be at least a hundred miles more. Any ideas or isit back to the dealership for service?
