Many things can make this happen I would inspect all hoses to see if none are collasped Also change the thermostat and coolant if not done in the past two years. Flush the old coolant out with a flush kit made by Prestone or equivalant You may see a big change in performance. If not a blockage can be in the heater core or radiator but I don't think so for this vehicle is 4 years old only
