I have figured out part of the problem. It is a design flaw with the sunroof drains. They are routed with very flimsy drain hose through the window frames and down int the frame rail of the car. If you pull off the front left and right kick panels it will expose a junction box for the electrical cannon plugs. If you pull that away far enough by releasing the clips you will see an access opening with a block of foam rubber in it. that foam rubber is very thick an pinches the drain hose up against a structural ridge on the body of the car. This causes the hose to collapse over time. the minute the smallest amount of dirt or debris gets in, it will re-clog. This is a manufacturers design flaw but if you take it to them they will say it is a clogged drain and it's not covered
