I check the coolant levels, and it's fine. What could be causing this? Is it possible the coolant line isn't circulating the coolant properly?

It sounds like your thermostat may be sticking or needs replaced. Or maybe your water pump is shot. But I would check my thermostat first, or have that checked first. Thats my guess...
