The 2016 Mazda CX-9 Sport is a somewhat easy vehicle to maintain. The parking light and the front turn signal are accessible by simply reaching behind the housing, allowing for reliable bulb changes. Monitoring the engine coolant will be simple given the open access to the reservoir. Changing the engine air filter won’t be a problem as the fasteners that secure the filter cover disengage without the use of tools.
However, the 2016 Mazda CX-9 Sport has quite a few difficulties. The wiper blades will be tedious to replace as they will require a tool or a cover removal in order to pry them off. Changing the non-LED tail lights may be a problem as they will first require tools to remove a panel or the entire bulb housing. Separate covers will need to be removed from underneath the vehicle in order to perform oil changes or coolant flushes.
