Mazda Mazda3 Problem Report
Mazda Mazda3 Steering effort heavy due to power steering fluid leak
If the steering effort feels heavy, this can be caused by a power steering fluid leak. Some models may have burrs on the return port of the power steering reservoir that create a gap between the hose and the port. Sanding the burrs off the port and replacing the power steering return hose is the repair for this concern.
