So this morning I start up and get the coolant low, add coolant display. It's a 2012. First time it's happened. I have no leaks. No smoke. When at operating temp upper hose is plyable when squeezed and a small amount of fluid can be seen going to reservoir and back out when I let go. Never a high temp, though it's been in the 30-40s. Fine this summer too. Never over 210degrees even pulling 10k in the summer.
